Cyclizine is only found in individuals that have used or taken this drug. It is a histamine H1 antagonist given by mouth or parenterally for the control of postoperative and drug-induced vomiting and in motion sickness. (From Martindale, The Extra Pharmacopoeia, 30th ed, p935)Vomiting (emesis) is essentially a protective mechanism for removing irritant or otherwise harmful substances from the upper GI tract. Emesis or vomiting is controlled by the vomiting centre in the medulla region of the brain, an important part of which is the chemotrigger zone (CTZ). The vomiting centre possesses neurons which are rich in muscarinic cholinergic and histamine containing synapses. These types of neurons are especially involved in transmission from the vestibular apparatus to the vomiting centre. Motion sickness principally involves overstimulation of these pathways due to various sensory stimuli. Hence the action of cyclizine which acts to block the histamine receptors in the vomiting centre and thus reduce activity along these pathways. Furthermore since cyclizine possesses anti-cholinergic properties as well, the muscarinic receptors are similarly blocked.

Indole is an aromatic heterocyclic organic compound. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing pyrrole ring. The participation of the nitrogen lone electron pair in the aromatic ring means that indole is not a base, and it does not behave like a simple amine. Indole is a microbial metabolite and it can be produced by bacteria as a degradation product of the amino acid tryptophan. It occurs naturally in human feces and has an intense fecal smell. At very low concentrations, however, indole has a flowery smell and is a constituent of many flower scents (such as orange blossoms) and perfumes. As a volatile organic compound, indole has been identified as a fecal biomarker of Clostridium difficile infection (PMID: 30986230). Natural jasmine oil, used in the perfume industry, contains around 2.5% of indole. Indole also occurs in coal tar. Indole has been found to be produced in a number of bacterial genera including Alcaligenes, Aspergillus, Escherichia, and Pseudomonas (PMID: 23194589, 2310183, 9680309). Indole plays a role in bacterial biofilm formation, bacterial motility, bacterial virulence, plasmid stability, and antibiotic resistance. It also functions as an intercellular signalling molecule (PMID: 26115989). Recently, it was determined that the bacterial membrane-bound histidine sensor kinase (HK) known as CpxA acts as a bacterial indole sensor to facilitate signalling (PMID: 31164470). It has been found that decreased indole concentrations in the gut promote bacterial pathogenesis, while increased levels of indole in the gut decrease bacterial virulence gene expression (PMID: 31164470). As a result, enteric pathogens sense a gradient of indole concentrations in the gut to migrate to different niches and successfully establish an infection.

Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) widely marketed under various trademarks including Act-3, Advil, Brufen, Motrin, Nuprin, and Nurofen. It is used for relief of symptoms of arthritis, primary dysmenorrhoea, and fever; Ibuprofen is an NSAID which is believed to work through inhibition of cyclooxygenase (COX), thus inhibiting prostaglandin synthesis. There are at least 2 variations of cyclooxygenase (COX-1 and COX-2), ibuprofen inhibits both COX-1 and COX-2. It appears that its analgesic, antipyretic, and anti-inflammatory activity are achieved principally through COX-2 inhibition; whereas COX-1 inhibition is responsible for its unwanted effects on platelet aggregation and the GI mucosa. As with other NSAIDs, ibuprofen inhibits platelet aggregation, but is not used therapeutically for this action since it is a minor and reversible effect. -- Wikipedia.

Petroleum distillates are also irritating to the skin. Petroleum distillates are aspiration hazards and may cause pulmonary damage, central nervous system depression, and cardiac effects such as cardiac arrhythmias. They may also affect the blood, immune system, liver, and kidney. At high amounts, central nervous system depression may also occur, with symptoms such as weakness, dizziness, slow and shallow respiration, unconsciousness, and convulsions.  Gastric lavage, emesis, and the administration of activated charcoal should be avoided, as vomiting increases the risk of aspiration.  Treatment is mainly symptomatic and supportive. Volatile hydrocarbons are absorbed mainly through the lungs, and may also enter the body after ingestion via aspiration.

Stearic acid, also known as octadecanoic acid or C18:0, belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Stearic acid (its ester is called stearate) is a saturated fatty acid that has 18 carbons and is therefore a very hydrophobic molecule that is practically insoluble in water.  It exists as a waxy solid.  In terms of its biosynthesis, stearic acid is produced from carbohydrates via the fatty acid synthesis machinery wherein acetyl-CoA contributes two-carbon building blocks, up to the 16-carbon palmitate, via the enzyme complex fatty acid synthase (FA synthase), at which point a fatty acid elongase is needed to further lengthen it.  After synthesis, there are a variety of reactions it may undergo, including desaturation to oleate via stearoyl-CoA desaturase (PMID: 16477801).  Stearic acid is found in all living organisms ranging from bacteria to plants to animals.  It is one of the useful types of saturated fatty acids that comes from many animal and vegetable fats and oils. For example, it is a component of cocoa butter and shea butter.  It is used as a food additive, in cleaning and personal care products, and in lubricants.  Its name comes from the Greek word stear, which means ‚Äòtallow‚Äô or ‚Äòhard fat‚Äô.
Nortriptyline hydrochloride, the <i>N</i>-demethylated active metabolite of amitriptyline, is a dibenzocycloheptene-derivative tricyclic antidepressant (TCA). TCAs are structurally similar to phenothiazines. They contain a tricyclic ring system with an alkyl amine substituent on the central ring. In non-depressed individuals, nortriptyline does not affect mood or arousal, but may cause sedation. In depressed individuals, nortriptyline exerts a positive effect on mood. TCAs are potent inhibitors of serotonin and norepinephrine reuptake. Secondary amine TCAs, such as nortriptyline, are more potent inhibitors of norepinephrine reuptake than tertiary amine TCAs, such as amitriptyline. TCAs also down-regulate cerebral cortical &beta;-adrenergic receptors and sensitize post-synaptic serotonergic receptors with chronic use. The antidepressant effects of TCAs are thought to be due to an overall increase in serotonergic neurotransmission. TCAs also block histamine-H<sub>1</sub> receptors, &alpha;<sub>1</sub>-adrenergic receptors and muscarinic receptors, which accounts for their sedative, hypotensive and anticholinergic effects (e.g. blurred vision, dry mouth, constipation, urinary retention), respectively. See toxicity section below for a complete listing of side effects. Nortriptyline exerts less anticholinergic and sedative side effects compared to the tertiary amine TCAs, amitriptyline and clomipramine. Nortriptyline may be used to treat depression, chronic pain (unlabeled use), irritable bowel syndrome (unlabeled use), diabetic neuropathy (unlabeled use), post-traumatic stress disorder (unlabeled use), and for migraine prophylaxis (unlabeled use).

Butethal is only found in individuals that have used or taken this drug. It is a sedative and a hypnotic drug.Butethal binds at a distinct binding site associated with a Cl<sup>-</sup> ionopore at the GABA<sub>A</sub> receptor, increasing the duration of time for which the Cl<sup>-</sup> ionopore is open. The post-synaptic inhibitory effect of GABA in the thalamus is, therefore, prolonged. All of these effects are associated with marked decreases in GABA-sensitive neuronal calcium conductance (gCa). The net result of barbiturate action is acute potentiation of inhibitory GABAergic tone. Barbiturates also act through potent (if less well characterized) and direct inhibition of excitatory AMPA-type glutamate receptors, resulting in a profound suppression of glutamatergic neurotransmission.
Phenobarbital is only found in individuals that have used or taken this drug. It is a barbituric acid derivative that acts as a nonselective central nervous system depressant.Phenobarbital acts on GABAA receptors, increasing synaptic inhibition. This has the effect of elevating seizure threshold and reducing the spread of seizure activity from a seizure focus. Phenobarbital may also inhibit calcium channels, resulting in a decrease in excitatory transmitter release. The sedative-hypnotic effects of phenobarbital are likely the result of its effect on the polysynaptic midbrain reticular formation, which controls CNS arousal.
Methyclothiazide is only found in individuals that have used or taken this drug. It is a thiazide diuretic with properties similar to those of hydrochlorothiazide. (From Martindale, The Extra Pharmacopoeia, 30th ed, p825)Methyclothiazide appears to block the active reabsorption of chloride and possibly sodium in the ascending loop of Henle, altering electrolyte transfer in the proximal tubule. This results in excretion of sodium, chloride, and water and, hence, diuresis. As a diuretic, methyclothiazide inhibits active chloride reabsorption at the early distal tubule via the Na-Cl cotransporter, resulting in an increase in the excretion of sodium, chloride, and water. Thiazides like methyclothiazide also inhibit sodium ion transport across the renal tubular epithelium through binding to the thiazide sensitive sodium-chloride transporter. This results in an increase in potassium excretion via the sodium-potassium exchange mechanism. The antihypertensive mechanism of methyclothiazide is less well understood although it may be mediated through its action on carbonic anhydrases in the smooth muscle or through its action on the large-conductance calcium-activated potassium (KCa) channel, also found in the smooth muscle.
Sulfapyridine is only found in individuals that have used or taken this drug. It is an antibacterial, potentially toxic, used to treat certain skin diseases. [PubChem] Sulfapyridine is a competitive inhibitor of the bacterial enzyme dihydropteroate synthetase. The inhibited reaction is necessary in these organisms for the synthesis of folic acid by means of processing the substrate para-aminobenzoic acid (PABA). Dihydropteroate synthetase activity is vital in the synthesis of folate, and folate is required for cells to make nucleic acids, such as DNA or RNA. So if DNA molecules cannot be built, the cell cannot divide.

These are an aldehyde with a chain length containing between 6 and 12 carbon atoms. (2E)-2-Heptenal is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Thus, (2E)-2-heptenal is considered to be a fatty aldehyde lipid molecule. Uremic toxins such as 2-Heptenal are actively transported into the kidneys via organic ion transporters (especially OAT3). (2E)-2-Heptenal is an almond, and fatty tasting compound. (2E)-2-Heptenal is found, on average, in the highest concentration within safflowers. (2E)-2-Heptenal has also been detected, but not quantified, in several different foods, such as roselles, common grapes, cucumbers, garden tomato, and evergreen blackberries. (2E)-2-Heptenal is a potentially toxic compound. Uremic toxins tend to accumulate in the blood either through dietary excess or through poor filtration by the kidneys. As a uremic toxin, this compound can cause uremic syndrome. Chronic exposure to uremic toxins can lead to a number of conditions including renal damage, chronic kidney disease and cardiovascular disease. This seems to be mediated by the direct binding or inhibition by uremic toxins of the enzyme NADPH oxidase (especially NOX4 which is abundant in the kidneys and heart) (A7868). Shortness of breath from fluid buildup in the space between the lungs and the chest wall (pleural effusion) can also be present. It can also cause changes in mental status, such as confusion, reduced awareness, agitation, psychosis, seizures, and coma.

In humans, 2,3-butanediol is oxidized to acetyl-CoA via acetoin. 2,3-Butanediol is also found in cocoa butter. 2,3-Butanediol can also be found in Bacillus, Klebsiella and Serratia (PMID:21272631).
Camphor, also known as (+)-camphor or (+)-bornan-2-one, is a member of the class of compounds known as bicyclic monoterpenoids. Bicyclic monoterpenoids are monoterpenoids containing exactly 2 rings, which are fused to each other. Camphor is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Within the cell, camphor is primarily located in the membrane (predicted from logP). Camphor is a waxy, flammable, white or transparent solid with a strong aroma. It is a terpenoid with the chemical formula C10H16O. It is found in many plants, such as in the wood of the camphor laurel (Cinnamomum camphora), a large evergreen tree found in Asia (particularly in Sumatra and Borneo islands, Indonesia) and also of the unrelated Kapur tree, a tall timber tree from the same region. It also occurs in some other related trees in the laurel family, notably Ocotea usambarensis and in the oil in rosemary leaves (Rosmarinus officinalis). The mint family contains 10 to 20% camphor, while camphorweed (Heterotheca) only contains some 5%. Camphor can also be synthetically produced from oil of turpentine. It is used for its scent, as an ingredient in cooking (mainly in India), as an embalming fluid, for medicinal purposes, and in religious ceremonies. A major source of camphor in Asia is camphor basil (the parent of African blue basil) (Wikipedia).
Quinone is also called 1,4-benzoquinone or cyclohexadienedione. Quinones are oxidized derivatives of aromatic compounds and are often readily made from reactive aromatic compounds with electron-donating substituents such as phenols and catechols, which increase the nucleophilicity of the ring and contributes to the large redox potential needed to break aromaticity. Derivatives of quinones are common constituents of biologically relevant molecules. Some serve as electron acceptors in electron transport chains such as those in photosynthesis (plastoquinone, phylloquinone), and aerobic respiration (ubiquinone). Quinone is a common constituent of biologically relevant molecules (e.g. Vitamin K1 is phylloquinone). A natural example of quinones as oxidizing agents is the spray of bombardier beetles. Hydroquinone is reacted with hydrogen peroxide to produce a fiery blast of steam, a strong deterent in the animal world.

Ethanolamine (MEA), also known as monoethanolamine, aminoethanol or glycinol, belongs to the class of organic compounds known as 1,2-aminoalcohols (or simply aminoalcohols). These are organic compounds containing an alkyl chain with an amine group bound to the C1 atom and an alcohol group bound to the C2 atom. Ethanolamine is a colorless, viscous liquid with an odor reminiscent of ammonia. In pharmaceutical formulations, ethanolamine is used primarily for buffering or preparation of emulsions. Ethanolamine can also be used as pH regulator in cosmetics. Biologically, ethanolamine is an initial precursor for the biosynthesis of two primary phospholipid classes, phosphatidylcholine (PC) and phosphatidylethanolamine (PE). In this regard, ethanolamine is the second-most-abundant head group for phospholipids. Ethanolamine serves as a precursor for a variety of N-acylethanolamines (NAEs). These are molecules that modulate several animal and plant physiological processes such as seed germination, plant‚Äìpathogen interactions, chloroplast development and flowering (PMID: 30190434). Ethanolamine, when combined with arachidonic acid (C20H32O2; 20:4, œâ-6), can also form the endocannabinoid anandamide. Ethanolamine can be converted to phosphoethanolamine via the enzyme known as ethanolamine kinase. the two substrates of this enzyme are ATP and ethanolamine, whereas its two products are ADP and O-phosphoethanolamine. In most plants ethanolamine is biosynthesized by decarboxylation of serine via a pyridoxal 5'-phosphate-dependent l-serine decarboxylase (SDC). Ethanolamine exists in all living species, ranging from bacteria to plants to humans. Ethanolamine has been detected, but not quantified in, several different foods, such as narrowleaf cattails, mung beans, blackcurrants, white cabbages, and bilberries.
Prochlorperazine is only found in individuals that have used or taken this drug. It is a phenothiazine antipsychotic used principally in the treatment of nausea; vomiting; and vertigo. It is more likely than chlorpromazine to cause extrapyramidal disorders. (From Martindale, The Extra Pharmacopoeia, 30th ed, p612)The mechanism of action of prochlorperazine has not been fully determined, but may be primarily related to its antidopaminergic effects. Prochlorperazine blocks the D2 somatodendritic autoreceptor, resulting in the blockade of postsynaptic dopamine receptors in the mesolimbic system and an increased dopamine turnover. Prochlorperazine also has anti-emetic effects, which can be attributed to dopamine blockade in the chemoreceptor trigger zone. Prochlorperazine also blocks anticholinergic and alpha-adrenergic receptors, the blockade of alpha(1)-adrenergic receptors resulting in sedation, muscle relaxation, and hypotension.

Adipic acid is an important inudstrial dicarboxylic acid with about 2.5 billion kilograms produced per year. It is used mainly in the production of nylon. It occurs relatively rarely in nature. It has a tart taste and is also used as an additive and gelling agent in jello or gelatins. It is also used in some calcium carbonate antacids to make them tart. Adipic acid has also been incorporated into controlled-release formulation matrix tablets to obtain pH-independent release for both weakly basic and weakly acidic drugs. Adipic acid in the urine and in the blood is typically exogenous in origin and is a good biomarker of jello consumption. In fact, a condition known as adipic aciduria is actually an artifact of jello consumption (PMID: 1779643). However, certain disorders (such as diabetes and glutaric aciduria type I.) can lead to elevated levels of adipic acid snd other dicarboxcylic acids (such as suberic acid) in urine (PMID: 17520433; PMID: 6778884). Moreover, adipic acid is also found to be associated with 3-hydroxy-3-methylglutaryl-CoA lyase deficiency, carnitine-acylcarnitine translocase deficiency, malonyl-Coa decarboxylase deficiency, and medium Chain acyl-CoA dehydrogenase deficiency, which are inborn errors of metabolism.

Caproic acid, also known as hexanoic acid or C6:0, is a medium-chain fatty acid. Medium-chain fatty acids (MCFA) are fatty acids with aliphatic tails of 6 to 12 carbons, which can form medium-chain triglycerides. Caproic acid is a colourless oily liquid that smells like cheese with an overlying waxy or barnyard odor like that of goats or other barnyard animals. Its name comes from the Latin word capra, meaning "goat". Two other fatty acids are named after goats: caprylic acid (C8) and capric acid (C10). Along with caproic acid, they account for 15% of the fat in goat's milk. Caproic acid is a fatty acid found naturally in various animal fats and oils. While generally more abundant in animals, caproic acid is found in all organisms ranging from bacteria to plants to animals. Caproic acid is one of the chemicals that gives the decomposing fleshy seed coat of the ginkgo fruit its characteristic unpleasant odor. It is also one of the components of vanilla and cheese. Industrially, the primary use of caproic acid is in the manufacture of its esters for use as artificial flavors and in the manufacture of hexyl derivatives, such as hexylphenols. Caproic acid has been associated with medium chain acyl-CoA dehydrogenase deficiency, which is an inborn error of metabolism. As a relatively volatile organic compound, caproic acid has been identified as a fecal biomarker of Clostridium difficile infection (PMID: 30986230).

Amobarbital is only found in individuals that have used or taken this drug. It is a barbiturate with hypnotic and sedative properties (but not antianxiety). Adverse effects are mainly a consequence of dose-related CNS depression and the risk of dependence with continued use is high. (From Martindale, The Extra Pharmacopoeia, 30th ed, p565)Amobarbital (like all barbiturates) works by binding to the GABAA receptor at either the alpha or the beta sub unit. These are binding sites that are distinct from GABA itself and also distinct from the benzodiazepine binding site. Like benzodiazepines, barbiturates potentiate the effect of GABA at this receptor. This GABAA receptor binding decreases input resistance, depresses burst and tonic firing, especially in ventrobasal and intralaminar neurons, while at the same time increasing burst duration and mean conductance at individual chloride channels; this increases both the amplitude and decay time of inhibitory postsynaptic currents. In addition to this GABA-ergic effect, barbiturates also block the AMPA receptor, a subtype of glutamate receptor. Glutamate is the principal excitatory neurotransmitter in the mammalian CNS. Amobarbital also appears to bind neuronal nicotinic acetylcholine receptors.

It reacts at the NH nitrogen, attacking alkylating and acylating compounds. It is not particularly susceptible to electrophilic attacks at the carbon atoms, and most of these reactions are substitutions that keep the aromaticity intact. One can see from the resonance structure that the carbon-2 is the carbon most likely to have a nucleophile attack it, but in general nucleophilic substitutions are difficult with imidazole. Imidazole is incorporated into many important biological molecules. The most obvious is the amino acid histidine, which has an imidazole side chain. histidine is present in many proteins and enzymes and plays a vital part in the structure and binding functions of hemoglobin.

Oxazepam is only found in individuals that have used or taken this drug. It is an intermediate-acting benzodiazepine used to treat alcohol withdrawal and anxiety disorders. It is a metabolite of diazepam, prazepam, temazepam, and clorazepate, and has moderate amnesic, anxiolytic, anticonvulsant, hypnotic, sedative, and skeletal muscle relaxant properties compared to other benzodiazepines (Wikipedia). Like other benzodiazepines, oxazepam exerts its anxiolytic effects by potentiating the effect of gamma-aminobutyric acid (GABA) on GABA-A receptors through a cooperative mechanism of action. GABA receptors are ionotropic chloride-linked channel receptors that produce inhibitory postsynaptic potentials. When activated by GABA, the GABA receptor/chloride ionophore complex undergoes a conformational change that allows the passage of chloride ions through the channel. Benzodiazepines are believed to exert their effect by increasing the effect of GABA at its receptor. Benzodiazepine binding increases chloride conductance in the presence of GABA by increasing the frequency at which the channel opens. In contrast, barbiturates increase chloride conductance in the presence of GABA by prolonging the time in which the channel remains open. There are 18 subtypes of the GABA receptor subunits. The &alpha;<sub>2</sub> subunit of the &alpha;<sub>2</sub>&beta;<sub>3</sub>&gamma;<sub>2</sub> receptor complex is thought to mediate anxiolytic effects while the &alpha;<sub>1</sub> subunit of the &alpha;<sub>1</sub>&beta;<sub>2</sub>&gamma;<sub>2</sub> receptor complex is thought to mediate sedative, anticonvulsant, and anterograde amnesia effects.

Prednisolone is only found in individuals that have used or taken this drug. It is a glucocorticoid with the general properties of the corticosteroids. It is the drug of choice for all conditions in which routine systemic corticosteroid therapy is indicated, except adrenal deficiency states. [PubChem]Glucocorticoids such as Prednisolone can inhibit leukocyte infiltration at the site of inflammation, interfere with mediators of inflammatory response, and suppress humoral immune responses. The antiinflammatory actions of glucocorticoids are thought to involve phospholipase A2 inhibitory proteins, lipocortins, which control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes. Prednisolone reduces inflammatory reaction by limiting the capillary dilatation and permeability of the vascular structures. These compounds restrict the accumulation of polymorphonuclear leukocytes and macrophages and reduce the release of vasoactive kinins. Recent research suggests that corticosteroids may inhibit the release of arachidonic acid from phospholipids, thereby reducing the formation of prostaglandins. Prednisolone is a glucocorticoid receptor agonist. On binding, the corticoreceptor-ligand complex translocates itself into the cell nucleus, where it binds to many glucocorticoid response elements (GRE) in the promoter region of the target genes. The DNA bound receptor then interacts with basic transcription factors, causing an increase or decrease in expression of specific target genes, including suppression of IL2 (interleukin 2) expression.
It is used as a food additive .
Trans-octen-2-al, also known as (E)-2-octenal or 2-octenal, (E)-isomer, is a member of the class of compounds known as medium-chain aldehydes.

2-Methylhippuric acid is an acyl glycine. Acyl glycines are normally minor metabolites of fatty acids. However, the excretion of certain acyl glycines is increased in several inborn errors of metabolism. In certain cases, the measurement of these metabolites in body fluids can be used to diagnose disorders associated with mitochondrial fatty acid beta-oxidation. Acyl glycines are produced through the action of glycine N-acyltransferase (EC 2.3.1.13) which is an enzyme that catalyzes the chemical reaction: acyl-CoA + glycine <--> CoA + N-acylglycine. 2-Methylhippuric acid is a metabolite of xylene which is an aromatic hydrocarbon widely used as a solvant. Its level can be measured in the urine of workers exposed to xylene (PMID:8689499). 2-Methylhippuric acid is an endogenous phenolic acid metabolite detected after the consumption of whole grain.

Amobarbital is only found in individuals that have used or taken this drug. It is a barbiturate with hypnotic and sedative properties (but not antianxiety). Adverse effects are mainly a consequence of dose-related CNS depression and the risk of dependence with continued use is high. (From Martindale, The Extra Pharmacopoeia, 30th ed, p565)Amobarbital (like all barbiturates) works by binding to the GABAA receptor at either the alpha or the beta sub unit. These are binding sites that are distinct from GABA itself and also distinct from the benzodiazepine binding site. Like benzodiazepines, barbiturates potentiate the effect of GABA at this receptor. This GABAA receptor binding decreases input resistance, depresses burst and tonic firing, especially in ventrobasal and intralaminar neurons, while at the same time increasing burst duration and mean conductance at individual chloride channels; this increases both the amplitude and decay time of inhibitory postsynaptic currents. In addition to this GABA-ergic effect, barbiturates also block the AMPA receptor, a subtype of glutamate receptor. Glutamate is the principal excitatory neurotransmitter in the mammalian CNS. Amobarbital also appears to bind neuronal nicotinic acetylcholine receptors.

This could make 4-methyl-3-penten-2-one a potential biomarker for the consumption of these foods. With regards to humans, 4-Methyl-3-penten-2-one has been linked to the inborn metabolic disorder celiac disease.
Acetohexamide is only found in individuals that have used or taken this drug. It is a sulfonylurea hypoglycemic agent that is metabolized in the liver to 1-hydrohexamide. [PubChem]Sulfonylureas such as acetohexamide bind to an ATP-dependent K<sup>+</sup> channel on the cell membrane of pancreatic beta cells. This inhibits a tonic, hyperpolarizing outflux of potassium, which causes the electric potential over the membrane to become more positive. This depolarization opens voltage-gated Ca<sup>2+</sup> channels. The rise in intracellular calcium leads to increased fusion of insulin granulae with the cell membrane, and therefore increased secretion of (pro)insulin.

Butethal is only found in individuals that have used or taken this drug. It is a sedative and a hypnotic drug.Butethal binds at a distinct binding site associated with a Cl<sup>-</sup> ionopore at the GABA<sub>A</sub> receptor, increasing the duration of time for which the Cl<sup>-</sup> ionopore is open. The post-synaptic inhibitory effect of GABA in the thalamus is, therefore, prolonged. All of these effects are associated with marked decreases in GABA-sensitive neuronal calcium conductance (gCa). The net result of barbiturate action is acute potentiation of inhibitory GABAergic tone. Barbiturates also act through potent (if less well characterized) and direct inhibition of excitatory AMPA-type glutamate receptors, resulting in a profound suppression of glutamatergic neurotransmission.
Octadenol is a fatty alcohol present in human and is normally incorporated into plasmalogen lipids. Patients with the autosomal recessive form of rhizomelic chondrodysplasia punctata (AR-RCDP) have elevated octadenol levels, but tended to be normal in other generalized peroxisomal disorders such as neonatal adrenoleukodystrophy and Zellweger syndrome (peroxisomal disorders are deficient in the incorporation of fatty alcohol into plasmalogen lipids). (PMID:8373640). Sjogren-Larsson syndrome is defined by the triad of ichthyosis, mental retardation, and spasticity, and patients accumulate fatty alcohols such as Octadenol in the plasma and cultured fibroblasts. (PMID:2241202). Sjogren-Larsson syndrome (SLS) is an autosomal recessive disorder associated with reduced activity of the fatty alcohol: NAD+ oxidoreductase complex (FAO).

Benzaldehyde is occasionally found as a volatile component of urine. Benzaldehyde is an aromatic aldehyde used in cosmetics as a denaturant, a flavoring agent, and as a fragrance. Currently used in only seven cosmetic products, its highest reported concentration of use was 0.5% in perfumes. Benzaldehyde is a generally regarded as safe (GRAS) food additive in the United States and is accepted as a flavoring substance in the European Union. Because Benzaldehyde rapidly metabolizes to Benzoic Acid in the skin, the available dermal irritation and sensitization data demonstrating no adverse reactions to Benzoic Acid were considered supportive of the safety of Benzaldehyde. Benzaldehyde is absorbed through skin and by the lungs, distributes to all well-perfused organs, but does not accumulate in any specific tissue type. After being metabolized to benzoic acid, conjugates are formed with glycine or glucuronic acid, and excreted in the urine. Several studies have suggested that Benzaldehyde can have carcinostatic or antitumor properties. Overall, at the concentrations used in cosmetics, Benzaldehyde was not considered a carcinogenic risk to humans. Although there are limited irritation and sensitization data available for Benzaldehyde, the available dermal irritation and sensitization data and ultraviolet (UV) absorption and phototoxicity data demonstrating no adverse reactions to Benzoic Acid support the safety of Benzaldehyde as currently used in cosmetic products. (PMID:16835129, Int J Toxicol. 2006;25 Suppl 1:11-27.).

Aniline is an organic chemical compound, specifically a primary aromatic amine. It consists of a benzene ring attached to an amino group. Aniline is oily and, although colorless, it can be slowly oxidized and resinified in air to form impurities which can give it a red-brown tint. Its boiling point is 184 degree centigrade and its melting point is -6 degree centegrade. It is a liquid at room temperature. Like most volatile amines, it possesses a somewhat unpleasant odour of rotten fish, and also has a burning aromatic taste; it is a highly acrid poison. It ignites readily, burning with a large smoky flame. Aniline reacts with strong acids to form salts containing the anilinium (or phenylammonium) ion (C6H5-NH3+), and reacts with acyl halides (such as acetyl chloride (ethanoyl chloride), CH3COCl) to form amides. The amides formed from aniline are sometimes called anilides, for example CH3-CO-NH-C6H5 is acetanilide, for which the modern name is N-phenyl ethanamide. Like phenols, aniline derivatives are highly reactive in electrophilic substitution reactions. For example, sulfonation of aniline produces sulfanilic acid, which can be converted to sulfanilamide. Sulfanilamide is one of the sulfa drugs which were widely used as antibacterial in the early 20th century. Aniline was first isolated from the destructive distillation of indigo in 1826 by Otto Unverdorben. In 1834, Friedrich Runge isolated from coal tar a substance which produced a beautiful blue color on treatment with chloride of lime; this he named kyanol or cyanol. In 1841, C. J. Fritzsche showed that by treating indigo with caustic potash it yielded an oil, which he named aniline, from the specific name of one of the indigo-yielding plants, Indigofera anil, anil being derived from the Sanskrit, dark-blue.

The major progestational steroid that is secreted primarily by the corpus luteum and the placenta. Progesterone acts on the uterus, the mammary glands and the brain. It is required in embryo implantation, pregnancy maintenance, and the development of mammary tissue for milk production. Progesterone, converted from pregnenolone, also serves as an intermediate in the biosynthesis of gonadal steroid hormones and adrenal corticosteroids. Progesterone is a C-21 steroid hormone involved in the female menstrual cycle, pregnancy (supports gestation) and embryogenesis of humans and other species. Progesterone belongs to a class of hormones called progestagens, and is the major naturally occurring human progestagen. During implantation and gestation, progesterone appears to decrease the maternal immune response to allow for the acceptance of the pregnancy. Progesterone decreases contractility of the uterine smooth muscle. The fetus metabolizes placental progesterone in the production of adrenal mineralo- and glucosteroids. A drop in progesterone levels is possibly one step that facilitates the onset of labor. In addition progesterone inhibits lactation during pregnancy. The fall in progesterone levels following delivery is one of the triggers for milk production. Progesterone is found to be associated with pregnene hydroxylation deficiency, which is an inborn error of metabolism.

Phenylacetylglycine is an acyl glycine. Acyl glycines are normally minor metabolites of fatty acids. However, the excretion of certain acyl glycines is increased in several inborn errors of metabolism. In certain cases the measurement of these metabolites in body fluids can be used to diagnose disorders associated with mitochondrial fatty acid beta-oxidation. Acyl glycines are produced through the action of glycine N-acyltransferase (EC 2.3.1.13) which is an enzyme that catalyzes the chemical reaction:. acyl-CoA + glycine < -- > CoA + N-acylglycine. Phenylacetylglycine or PAG is a glycine conjugate of phenylacetic acid. Phenylacetic acid may arise from exposure to styrene (plastic) or through the consumption of fruits and vegetables. Phenylacetic acid is used in some perfumes, possessing a honey-like odour in low concentrations, and is also used in penicillin G production. PAG is a putative biomarker of phospholipidosis. Urinary PAG is elevated in animals exhibiting abnormal phospholipid accumulation in many tissues and may thus be useful as a surrogate biomarker for phospholipidosis. (PMID: 15764292) The presence of phenylacetylglycine in urine has been confirmed for dogs, rats and mice. However, the presence of this compound in human urine is controversial. GC-MS studies have not found this compound (PMID: 7492634) while NMR studies claimed to have identified it (PMID: 21167146). It appears that phenylacetylglycine may sometimes be mistaken for phenylacetylglutamine via NMR.

trans-Ferulic acid is a highly abundant phenolic phytochemical which is present in plant cell walls. Ferulic acid is a phenolic acid that can be absorbed by the small intestine and excreted through the urine. It is one of the most abundant phenolic acids in plants, varying from 5 g/kg in wheat bran to 9 g/kg in sugar-beet pulp and 50 g/kg in corn kernel. It occurs primarily in seeds and leaves both in its free form (albeit rarely) and covalently linked to lignin and other biopolymers. It is usually found as ester cross-links with polysaccharides in the cell wall, such as arabinoxylans in grasses, pectin in spinach and sugar beet, and xyloglucans in bamboo. It also can cross-link with proteins. Due to its phenolic nucleus and an extended side chain conjugation (carbohydrates and proteins), it readily forms a resonance-stabilized phenoxy radical which accounts for its potent antioxidant potential. Food supplementation with curcumin and ferulic acid is considered a nutritional approach to reducing oxidative damage and amyloid pathology in Alzheimer disease (PMID:17127365, 1398220, 15453708, 9878519).

This could make 3-methylheptane a potential biomarker for the consumption of these foods.
Ethosuximide is only found in individuals that have used or taken this drug. It is an anticonvulsant especially useful in the treatment of absence seizures unaccompanied by other types of seizures. [PubChem]Binds to T-type voltage sensitive calcium channels. Voltage-sensitive calcium channels (VSCC) mediate the entry of calcium ions into excitable cells and are also involved in a variety of calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, gene expression, cell motility, cell division and cell death. The isoform alpha-1G gives rise to T-type calcium currents. T-type calcium channels belong to the "low-voltage activated (LVA)" group and are strongly blocked by mibefradil. A particularity of this type of channels is an opening at quite negative potentials and a voltage-dependent inactivation. T-type channels serve pacemaking functions in both central neurons and cardiac nodal cells and support calcium signaling in secretory cells and vascular smooth muscle. They may also be involved in the modulation of firing patterns of neurons which is important for information processing as well as in cell growth processes.

Acetohexamide is only found in individuals that have used or taken this drug. It is a sulfonylurea hypoglycemic agent that is metabolized in the liver to 1-hydrohexamide. [PubChem]Sulfonylureas such as acetohexamide bind to an ATP-dependent K<sup>+</sup> channel on the cell membrane of pancreatic beta cells. This inhibits a tonic, hyperpolarizing outflux of potassium, which causes the electric potential over the membrane to become more positive. This depolarization opens voltage-gated Ca<sup>2+</sup> channels. The rise in intracellular calcium leads to increased fusion of insulin granulae with the cell membrane, and therefore increased secretion of (pro)insulin.
Isorhamnetin is the methylated metabolite of quercetin. Quercetin is an important dietary flavonoid with in vitro antioxidant activity. However, it is found in human plasma as conjugates with glucuronic acid, sulfate or methyl groups, with no significant amounts of free quercetin present. Isorhamnetin prevents endothelial cell injuries from oxidized LDL via inhibition of lectin-like ox-LDL receptor-1 upregulation, interference of ox-LDL-mediated intracellular signaling pathway (p38MAPK activation, NF-kappaB nuclear translocation, eNOS expression) and the antioxidant activity of isorhamnetin. Isorhamnetin prevents endothelial dysfunction, superoxide production, and overexpression of p47phox induced by angiotensin II. Isorhamnetin appears to be a potent drug against esophageal cancer due to its in vitro potential to not only inhibit proliferation but also induce apoptosis of Eca-109 cells.

Salicylic acid is a monohydroxybenzoic acid that is benzoic acid with a hydroxy group at the ortho position. It is obtained from the bark of the white willow and wintergreen leaves. It has a role as an antiinfective agent, an antifungal agent, a keratolytic drug, an EC 1.11.1.11 (L-ascorbate peroxidase) inhibitor, a plant metabolite, an algal metabolite and a plant hormone. It is a conjugate acid of a salicylate. It is a colorless solid, it is a precursor to and a metabolite of aspirin (acetylsalicylic acid). It is a plant hormone. The name is from Latin salix for willow tree. It is an ingredient in some anti-acne products. Salts and esters of salicylic acid are known as salicylates. Salicylic acid modulates COX1 enzymatic activity to decrease the formation of pro-inflammatory prostaglandins. Salicylate may competitively inhibit prostaglandin formation. Salicylate's antirheumatic (nonsteroidal anti-inflammatory) actions are a result of its analgesic and anti-inflammatory mechanisms. Salicylic acid works by causing the cells of the epidermis to slough off more readily, preventing pores from clogging up, and allowing room for new cell growth. Salicylic acid inhibits the oxidation of uridine-5-diphosphoglucose (UDPG) competitively with nicotinamide adenosine dinucleotide and noncompetitively with UDPG. It also competitively inhibits the transferring of glucuronyl group of uridine-5-phosphoglucuronic acid to the phenolic acceptor. The wound-healing retardation action of salicylates is probably due mainly to its inhibitory action on mucopolysaccharide synthesis. Salicylic acid is biosynthesized from the amino acid phenylalanine. In Arabidopsis thaliana, it can be synthesized via a phenylalanine-independent pathway.

Mexiletine is only found in individuals that have used or taken this drug. It is an antiarrhythmic agent pharmacologically similar to lidocaine. It may have some anticonvulsant properties. [PubChem]Mexiletine, like lidocaine, inhibits the inward sodium current required for the initiation and conduction of impulses, thus reducing the rate of rise of the action potential, Phase 0. It achieves this reduced sodium current by inhibiting sodium channels. Mexiletine decreases the effective refractory period (ERP) in Purkinje fibers in the heart. The decrease in ERP is of lesser magnitude than the decrease in action potential duration (APD), which results in an increase in the ERP/APD ratio. It does not significantly affect resting membrane potential or sinus node automaticity, left ventricular function, systolic arterial blood pressure, atrioventricular (AV) conduction velocity, or QRS or QT intervals
beta-Aminopropionitrile is a toxic amino-acid derivative. On an unusual case of the Cantrell-sequence in a premature infant with associated dysmelia, aplasia of the right kidney, cerebellar hypoplasia and circumscribed aplasia of the cutis, maternal history suggested an occupational exposure to aminopropionitriles prior to pregnancy. The characteristic features of the Cantrell-sequence--anterior thoraco-abdominal wall defect with ectopia cordis and diaphragm, sternum, pericardium, and heart defects--have been observed in animals following maternal administration of beta-aminopropionitrile. Some species of lathyrus (chickling pea, Lathyrus sativus- related), notably Lathyrus odoratus, are unable to induce human lathyrism but contain beta-aminopropionitrile, that induces pathological changes in bone ("osteolathyrism") and blood vessels ("angiolathyrism") of experimental animals without damaging the nervous system. The administration of beta-aminopropionitrile has been proposed for pharmacological control of unwanted scar tissue in human beings. beta-Aminopropionitrile is a reagent used as an intermediate in the manufacture of beta-alanine and pantothenic acid.

Citral has also been reported to be found in Cannabis sativa (PMID:6991645 , 26657499 ). Citral has a strong lemon (citrus) odor. Neral's lemon odor is less intense, but sweeter. Citral is therefore an aroma compound used in perfumery for its citrus effect. Citral is also used as a flavor and for fortifying lemon oil. It has strong antimicrobial qualities (PMID:28974979 ) and pheromonal effects in nematodes and insects (PMID:26973536 ). Citral is used in the synthesis of vitamin A, lycopene, ionone, and methylionone (a compound used to mask the smell of smoke).
Camphor, also known as (+)-camphor or (+)-bornan-2-one, is a member of the class of compounds known as bicyclic monoterpenoids. Bicyclic monoterpenoids are monoterpenoids containing exactly 2 rings, which are fused to each other. Camphor is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Within the cell, camphor is primarily located in the membrane (predicted from logP). Camphor is a waxy, flammable, white or transparent solid with a strong aroma. It is a terpenoid with the chemical formula C10H16O. It is found in many plants, such as in the wood of the camphor laurel (Cinnamomum camphora), a large evergreen tree found in Asia (particularly in Sumatra and Borneo islands, Indonesia) and also of the unrelated Kapur tree, a tall timber tree from the same region. It also occurs in some other related trees in the laurel family, notably Ocotea usambarensis and in the oil in rosemary leaves (Rosmarinus officinalis). The mint family contains 10 to 20% camphor, while camphorweed (Heterotheca) only contains some 5%. Camphor can also be synthetically produced from oil of turpentine. It is used for its scent, as an ingredient in cooking (mainly in India), as an embalming fluid, for medicinal purposes, and in religious ceremonies. A major source of camphor in Asia is camphor basil (the parent of African blue basil) (Wikipedia).
A study of the effects of chlorpyrifos on humans exposed over time showed that people exposed to high levels have autoimmune antibodies that are common in people with autoimmune disorders. There is a strong correlation to chronic illness associated with autoimmune disorders after exposure to chlorpyrifos. Among 50 farm pesticides studied, chlorpyrifos was one of two found to be associated with higher risks of lung cancer among frequent pesticide applicators than among infrequent or non-users. Pesticide applicators as a whole were found to have a 50% lower cancer risk than the general public, which is attributable to the nearly 50% lower smoking rate found among farm workers. However, applicators of chlorpyrifos had a 15% lower cancer risk than the general public, which the study suggests indicates a likely link between chlorpyrifos application and lung cancer. Chlorpyrifos (IUPAC name: O,O-diethyl O-3,5,6-trichloropyridin-2-yl phosphorothioate) is a crystalline organophosphate insecticide. It was introduced in 1965 by Dow Chemical Company and is known by many trade names (see table), including Dursban and Lorsban. It acts on the nervous system of insects by inhibiting acetylcholinesterase. Chlorpyrifos is an organophosphate, with potential for both acute toxicity at larger amounts and neurological effects in fetuses and children even at very small amounts. For acute effects, the EPA classifies chlorpyrifos as Class II: moderately toxic. The oral LD50 for chlorpyrifos in experimental animals is 32 to 1000 mg/kg.

(From AMA Drug Evaluations Annual, 1994, p378)Trimethadione reduces T-type calcium currents in thalamic neurons, including thalamic relay neurons. It does so via the inhibition of voltage dependent T-type calcium channels. This raises the threshold for repetitive activity in the thalamus, and inhibits corticothalamic transmission. Thus, the abnormal thalamocortical rhythmicity, which is thought to underlie the 3-Hz spike-and-wave discharge seen on electroencephalogram(EEG) with absence seizures, is dampened.

They contain a tricyclic ring system with an alkyl amine substituent on the central ring. In non-depressed individuals, desipramine does not affect mood or arousal, but may cause sedation. In depressed individuals, desipramine exerts a positive effect on mood. TCAs are potent inhibitors of serotonin and norepinephrine reuptake. Secondary amine TCAs, such as desipramine and nortriptyline, are more potent inhibitors of norepinephrine reuptake than tertiary amine TCAs, such as amitriptyline and doxepine. TCAs also down-regulate cerebral cortical &beta;-adrenergic receptors and sensitize post-synaptic serotonergic receptors with chronic use. The antidepressant effects of TCAs are thought to be due to an overall increase in serotonergic neurotransmission. TCAs also block histamine-H<sub>1</sub> receptors, &alpha;<sub>1</sub>-adrenergic receptors and muscarinic receptors, which accounts for their sedative, hypotensive and anticholinergic effects (e.g. blurred vision, dry mouth, constipation, urinary retention), respectively. See toxicity section below for a complete listing of side effects. Desipramine exerts less anticholinergic and sedative side effects compared to tertiary amine TCAs, such as amitriptyline and clomipramine.

Ethopropazine is only found in individuals that have used or taken this drug.Ethopropazine (also known as profenamine hydrochloride) is a medication derived from phenothiazine. It is primarily used as an antidyskinetic to treat parkinsonism. It is sold under the trade names Parsidol in the United States and Parsidan in Canada.Ethopropazine's antiparkinson action can be attributed to its anticholinergic properties. Ethopropazine partially blocks central (striatal) cholinergic receptors, thereby helping to balance cholinergic and dopaminergic activity in the basal ganglia; salivation may be decreased, and smooth muscle may be relaxed. Drug-induced extrapyramidal symptoms and those due to parkinsonism may be relieved, but tardive dyskinesia is not alleviated and may be aggravated by anticholinergic effects. Ethopropazine's local anesthetic effect is due to its antagonism of the NMDA glutamate receptor. Glutamate is recognized as an important transmitter in nociceptive pathways, and the N-methyl-D-aspartate (NMDA) subtype of the glutamate receptor, in particular, has been implicated in the mediation of neuropathic pain. Excessive release of glutamate at NMDA receptors on dorsal horn neurons of the spinal cord results in hyperactivation and hypersensitivity of these receptors (perceived as hyperalgesia), thought to be an integral feature of neuropathic pain.

Isocarboxazid is only found in individuals that have used or taken this drug. It is an MAO inhibitor that is effective in the treatment of major depression, dysthymic disorder, and atypical depression. It also is useful in the treatment of panic disorder and the phobic disorders. (From AMA, Drug Evaluations Annual, 1994, p311). Isocarboxazid works by irreversibly blocking the action of a chemical substance known as monoamine oxidase (MAO) in the nervous system. MAO subtypes A and B are involved in the metabolism of serotonin and catecholamine neurotransmitters such as epinephrine, norepinephrine, and dopamine. Isocarboxazid, as a nonselective MAO inhibitor, binds irreversibly to monoamine oxidase&ndash;A (MAO-A) and monoamine oxidase&ndash;B (MAO-B). The reduced MAO activity results in an increased concentration of these neurotransmitters in storage sites throughout the central nervous system (CNS) and sympathetic nervous system. This increased availability of one or more monoamines is the basis for the antidepressant activity of MAO inhibitors.

This colourless crystalline solid is used in peptide synthesis. It is well known to form hydrogen bonded structures somewhat related to the base-pairing mechanism found in RNA and DNA. It is also a classic case of a molecule that exists as tautomers. Some publications only focus one of the two possible patterns, and neglect the influence of the other. For example, to calculation of the energy difference of the two tautomers in a non-polar solution will lead to a wrong result if a large quantity of the substance is on the side of the dimer in an equilibrium. The direct tautomerisation is not energetically favoured, but a dimerisation followed by a double proton transfer and dissociation of the dimer is a self catalytic path from one tautomer to the other. Protic solvents also mediate the proton transfer during the tautomerisation.

Fischer esterification gives diethyl malonate: One of the principal uses of this compound is in the malonic ester synthesis. It occurs naturally in grapes and strawberries as a colourless liquid with an apple-like odour, and is used in perfumes. Malonic acid is a rather simple dicarboxylic acid, with the two carboxyl groups close together. The hydrogen atoms on a carbon adjacent to two carbonyl groups are even more acidic because the carbonyl groups help stabilize the carbanion resulting from the removal of that proton. Like many other esters, this compound can undergo the Claisen ester condensation. This alkylated 1,3-dicarbonyl compound (3) readily undergoes decarboxylation with loss of carbon dioxide, to give a substituted acetic acid, using Sodium ethoxide as the preferred base. The use of aqueous sodium hydroxide may give the base hydrolysis products: sodium malonate and ethanol.

A "cardboard-like" off-flavour is frequently associated with dehydrated milk products. This effect is highly correlated with the headspace concentration of hexanal. (Food Chemistry. Volume 107, Issue 1, 1 March 2008, Pages 558-569, PMID:17934948, 17487452).

Diethylpropion is only found in individuals that have used or taken this drug. It is a appetite depressant considered to produce less central nervous system disturbance than most drugs in this therapeutic category. It is also considered to be among the safest for patients with hypertension. (From AMA Drug Evaluations Annual, 1994, p2290)Diethylpropion is an amphetamine that stimulates neurons to release or maintain high levels of a particular group of neurotransmitters known as catecholamines; these include dopamine and norepinephrine. High levels of these catecholamines tend to suppress hunger signals and appetite. Diethylpropion (through catecholamine elevation) may also indirectly affect leptin levels in the brain. It is theorized that diethylpropion can raise levels of leptin which signal satiety. It is also theorized that increased levels of the catecholamines are partially responsible for halting another chemical messenger known as neuropeptide Y. This peptide initiates eating, decreases energy expenditure, and increases fat storage.

5-Aminopentanoic acid (or 5-aminovalerate) is a lysine degradation product.  It can be produced both endogenously or through bacterial catabolism of lysine.  5-aminovalerate is formed via the following multi-step reaction: L-lysine leads to cadverine leads to L-piperideine leads 5-aminovalerate (PMID:405455).  In other words it is a metabolite of cadaverine which is formed via the intermediate, 1-piperideine (PMID:6436440).  Cadaverine is a foul-smelling diamine compound produced by protein hydrolysis during putrefaction of animal tissue. High levels of 5-aminovalerate in biofluids may indicate bacterial overgrowth or endogenous tissue necrosis.  In most cases  endogenous 5-aminovalerate is thought to be primarily a microbial metabolite produced by the gut or oral microflora, although it can be produced endogenously.  5-aminovalerate is a normal metabolite present in human saliva, with a tendency to elevated concentration in patients with chronic periodontitis. Bacterial contamination and decomposition of salivary proteins is primarily responsible for elevated salivary levels (PMID 3481959). Beyond being a general waste product, 5-aminovalerate is also believed to act as a methylene homologue of gamma-aminobutyric acid (GABA) and functions as a weak GABA agonist (PMID:4031870). It is also known as an antifibrinolytic amino acid analog and so it functions as a weak inhibitor of the blood clotting pathway (PMID:6703712). 5- aminovalerate is an in vivo substrate of 4-aminobutyrate:2-oxoglutarate aminotransferase (PMID:4031870). It can be found in Corynebacterium (PMID:27717386).
Stigmasterol is a phytosterol, meaning it is steroid derived from plants. As a food additive, phytosterols have cholesterol-lowering properties (reducing cholesterol absorption in intestines), and may act in cancer prevention. Phytosterols naturally occur in small amount in vegetable oils, especially soybean oil. One such phytosterol complex, isolated from vegetable oil, is cholestatin, composed of campesterol, stigmasterol, and brassicasterol, and is marketed as a dietary supplement. Sterols can reduce cholesterol in human subjects by up to 15%. The mechanism behind phytosterols and the lowering of cholesterol occurs as follows : the incorporation of cholesterol into micelles in the gastrointestinal tract is inhibited, decreasing the overall amount of cholesterol absorbed. This may in turn help to control body total cholesterol levels, as well as modify HDL, LDL and TAG levels. Many margarines, butters, breakfast cereals and spreads are now enriched with phytosterols and marketed towards people with high cholesterol and a wish to lower it. Stigmasterol is found to be associated with phytosterolemia, which is an inborn error of metabolism.
Etiocholanedione is a 5-beta metabolite product of the catabolism of androgens. Etiocholanedione has been identified as a ketosteroid and isolated from the urine of healthy and diseased persons.

Etiocholanedione has been identified as a metabolite of 17alpha-hydroxyprogesterone in some patients affected by congenital adrenal hyperplasia, although it doesn't appear to account for the masculinization observed in congenital hyperplasia. Etiocholanedione can be the product of microbial contamination of urine since a few organisms are able to synthesize it using endogenous steroids as substrates. Human axillary bacteria are able to produce small amounts of etiocholanedione from testosterone. (PMID: 12161001, 13795320, 11161304, 2026727). Etiocholanedione has been found to be a metabolite of Corynebacterium (PMID: 11161304).

Citral is therefore an aroma compound used in perfumery for its citrus effect. Citral is also used as a flavor and for fortifying lemon oil. It has strong antimicrobial qualities (PMID:28974979 ) and pheromonal effects in nematodes and insects (PMID:26973536 ). Citral is used in the synthesis of vitamin A, lycopene, ionone, and methylionone (a compound used to mask the smell of smoke).
Ethopropazine is only found in individuals that have used or taken this drug.Ethopropazine (also known as profenamine hydrochloride) is a medication derived from phenothiazine. It is primarily used as an antidyskinetic to treat parkinsonism. It is sold under the trade names Parsidol in the United States and Parsidan in Canada.Ethopropazine's antiparkinson action can be attributed to its anticholinergic properties. Ethopropazine partially blocks central (striatal) cholinergic receptors, thereby helping to balance cholinergic and dopaminergic activity in the basal ganglia; salivation may be decreased, and smooth muscle may be relaxed. Drug-induced extrapyramidal symptoms and those due to parkinsonism may be relieved, but tardive dyskinesia is not alleviated and may be aggravated by anticholinergic effects. Ethopropazine's local anesthetic effect is due to its antagonism of the NMDA glutamate receptor. Glutamate is recognized as an important transmitter in nociceptive pathways, and the N-methyl-D-aspartate (NMDA) subtype of the glutamate receptor, in particular, has been implicated in the mediation of neuropathic pain. Excessive release of glutamate at NMDA receptors on dorsal horn neurons of the spinal cord results in hyperactivation and hypersensitivity of these receptors (perceived as hyperalgesia), thought to be an integral feature of neuropathic pain.

beta-Sitosterol, a main dietary phytosterol found in plants, may have the potential for prevention and therapy for human cancer. Phytosterols are plant sterols found in foods such as oils, nuts, and vegetables. Phytosterols, in the same way as cholesterol, contain a double bond and are susceptible to oxidation, and are characterized by anti-carcinogenic and anti-atherogenic properties (PMID:13129445, 11432711). beta-Sitosterol is a phytopharmacological extract containing a mixture of phytosterols, with smaller amounts of other sterols, bonded with glucosides. These phytosterols are commonly derived from the South African star grass, Hypoxis rooperi, or from species of Pinus and Picea. The purported active constituent is termed beta-sitosterol. Additionally, the quantity of beta-sitosterol-beta-D-glucoside is often reported. Although the exact mechanism of action of beta-sitosterols is unknown, it may be related to cholesterol metabolism or anti-inflammatory effects (via interference with prostaglandin metabolism). Compared with placebo, beta-sitosterol improved urinary symptom scores and flow measures (PMID:10368239). A plant food-based diet modifies the serum beta-sitosterol concentration in hyperandrogenic postmenopausal women. This finding indicates that beta-sitosterol can be used as a biomarker of exposure in observational studies or as a compliance indicator in dietary intervention studies of cancer prevention (PMID:14652381). beta-Sitosterol induces apoptosis and activates key caspases in MDA-MB-231 human breast cancer cells (PMID:12579296).

Naphthalene is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Inhalation of naphthalene vapor has been associated with headaches, nausea, vomiting and dizziness. Naphthalene is the most abundant single component of coal tar so most of it is now industrially derived from coal tar. Aside from coal tar, trace amounts of naphthalene are produced by magnolias and some species of deer, as well as the Formosan subterranean termite, possibly produced by the termite as a repellant against "ants, poisonous fungi and nematode worms."[23] Some strains of the endophytic fungus Muscodor albus produce naphthalene among a range of volatile organic compounds, while Muscodor vitigenus produces naphthalene almost exclusively (PMID:12427963).

Polyethylene glycol (PEG) is a polyether compound with many applications from industrial manufacturing to medicine. PEG is also known as polyethylene oxide (PEO) or polyoxyethylene (POE), depending on its molecular weight. PEG, PEO, or POE refers to an oligomer or polymer of ethylene oxide. Polyethylene glycol is produced by the interaction of ethylene oxide with water, ethylene glycol, or ethylene glycol oligomers. PEG is the basis of a number of laxatives (e.g. macrogol-containing products such as Movicol and polyethylene glycol 3350, or SoftLax, MiraLAX, or GlycoLax). Whole bowel irrigation with polyethylene glycol and added electrolytes is used for bowel preparation before surgery or colonoscopy. PEG is used as an excipient in many pharmaceutical products. Lower-molecular-weight variants are used as solvents in oral liquids and soft capsules, whereas solid variants are used as ointment bases, tablet binders, film coatings, and lubricants (Wikipedia). It has been shown that polyethylene glycol can improve healing of spinal injuries in dogs. Earlier findings that polyethylene glycol can aid in nerve repair came from the University of Texas (Krause and Bittner). Polyethylene glycol is commonly used to fuse B-cells with myeloma cells in monoclonal antibody production. PEG has recently been proven to give better results in constipation patients than tegaserod. Since PEG is a flexible, water-soluble polymer, it can be used to create very high osmotic pressures (tens of atmospheres). It also is unlikely to have specific interactions with biological chemicals. These properties make PEG one of the most useful molecules for applying osmotic pressure in biochemistry experiments, particularly when using the osmotic stress technique. Polyethylene glycol has been shown to exhibit excitant, anesthetic, radical scavenger, anti-microbial, and laxative functions (PMID: 10726226, 9485637, 11179847, 19089178, 20011352).

Dicumarol is only found in individuals that have used or taken this drug. It is an oral anticoagulant that interferes with the metabolism of vitamin K. It is also used in biochemical experiments as an inhibitor of reductases. [PubChem]Dicumarol inhibits vitamin K reductase, resulting in depletion of the reduced form of vitamin K (vitamin KH2). As vitamin K is a cofactor for the carboxylation of glutamate residues on the N-terminal regions of vitamin K-dependent proteins, this limits the gamma-carboxylation and subsequent activation of the vitamin K-dependent coagulant proteins. The synthesis of vitamin K-dependent coagulation factors II, VII, IX, and X and anticoagulant proteins C and S is inhibited. Depression of three of the four vitamin K-dependent coagulation factors (factors II, VII, and X) results in decresed prothrombin levels and a decrease in the amount of thrombin generated and bound to fibrin. This reduces the thrombogenicity of clots.

Stigmasterol is a phytosterol, meaning it is steroid derived from plants. As a food additive, phytosterols have cholesterol-lowering properties (reducing cholesterol absorption in intestines), and may act in cancer prevention. Phytosterols naturally occur in small amount in vegetable oils, especially soybean oil. One such phytosterol complex, isolated from vegetable oil, is cholestatin, composed of campesterol, stigmasterol, and brassicasterol, and is marketed as a dietary supplement. Sterols can reduce cholesterol in human subjects by up to 15%. The mechanism behind phytosterols and the lowering of cholesterol occurs as follows : the incorporation of cholesterol into micelles in the gastrointestinal tract is inhibited, decreasing the overall amount of cholesterol absorbed. This may in turn help to control body total cholesterol levels, as well as modify HDL, LDL and TAG levels. Many margarines, butters, breakfast cereals and spreads are now enriched with phytosterols and marketed towards people with high cholesterol and a wish to lower it. Stigmasterol is found to be associated with phytosterolemia, which is an inborn error of metabolism.

beta-Sitosterol, a main dietary phytosterol found in plants, may have the potential for prevention and therapy for human cancer. Phytosterols are plant sterols found in foods such as oils, nuts, and vegetables. Phytosterols, in the same way as cholesterol, contain a double bond and are susceptible to oxidation, and are characterized by anti-carcinogenic and anti-atherogenic properties (PMID:13129445, 11432711). beta-Sitosterol is a phytopharmacological extract containing a mixture of phytosterols, with smaller amounts of other sterols, bonded with glucosides. These phytosterols are commonly derived from the South African star grass, Hypoxis rooperi, or from species of Pinus and Picea. The purported active constituent is termed beta-sitosterol. Additionally, the quantity of beta-sitosterol-beta-D-glucoside is often reported. Although the exact mechanism of action of beta-sitosterols is unknown, it may be related to cholesterol metabolism or anti-inflammatory effects (via interference with prostaglandin metabolism). Compared with placebo, beta-sitosterol improved urinary symptom scores and flow measures (PMID:10368239).

DMSO is also employed as a rinsing agent in the electronics industry and, in its deuterated form (DMSO-d6), is a useful solvent in NMR due to its ability to dissolve a wide range of chemical compounds and its minimal interference with the sample signals. In cryobiology DMSO has been used as a cryoprotectant and is still an important constituent of cryoprotectant vitrification mixtures used to preserve organs, tissues, and cell suspensions. It is particularly important in the freezing and long-term storage of embryonic stem cells and hematopoietic stem cell, which are often frozen in a mixture of 10% DMSO and 90% fetal calf serum. As part of an autologous bone marrow transplant the DMSO is re-infused along with the patient's own hematopoietic stem cell. Dimethyl sulfoxide is a by-product of wood pulping. One of the leading suppliers of DMSO is the Gaylord company in the USA. DMSO is frequently used as solvent in a number of chemical reactions. In particular it is an excellent reaction solvent for SN2 alkylations: it is possible to alkylate indoles with very high yields using potassium hydroxide as the base and a similar reaction also occurs with phenols. DMSO can be reacted with methyl iodide to form a sulfoxonium ion which can be reacted with sodium hydride to form a sulfur ylide. The methyl groups of DMSO are somewhat acidic in character (pKa=35) due to the stabilization of the resultant anions by the sulfoxide group.

Picolinic acid is a metabolite of the tryptophan catabolism. Picolinic acid is produced under inflammatory conditions and a costimulus with interferon-gamma (IFNgamma) of macrophage (Mphi) effector functions, is a selective inducer of the Mphi inflammatory protein-1alpha (MIP-1alpha) and -1beta (MIPs), two chemokines/cytokines involved in the elicitation of the inflammatory reactions and in the development of the Th1 responses. IFNgamma and picolinic acid have reciprocal effects on the production of MIPs chemokines and the expression of their receptor. The concerted action of IFNgamma and picolinic acid on MIP-1alpha/beta chemokine/receptor system is likely to be of pathophysiological significance and to represent an important regulatory mechanism for leukocyte recruitment and distribution into damaged tissues during inflammatory responses. Picolinic acid has an effect on the production of L-arginine-derived reactive nitrogen intermediates in macrophages, by augmenting IFN-gamma-induced NO2- production, and acts synergistically with IFN-gamma in activating macrophages. Children with acrodermatitis enteropathica (AE) are treated with oral zinc dipicolinate (zinc-PA). The concentration of picolinic acid in the plasma of asymptomatic children with AE was significantly less than that of normal children. However, oral treatment with PA alone is ineffective. The results support the hypothesis that the genetic defect in AE is in the tryptophan pathway, although the role of PA in zinc metabolism remains to be defined. (PMID:15206716, 8473748, 1701787, 6694049).

Pyridoxine, also known vitamin B6, is commonly found in food and is used as a dietary supplement. Pyridoxine is an essential nutrient, meaning the body cannot synthesize it, and it must be obtained from the diet. Sources in the diet include fruit, vegetables, and grain. Although pyridoxine and vitamin B6 are still frequently used as synonyms, especially by medical researchers, this practice is sometimes misleading (PMID: 2192605). Technically, pyridoxine is one of the compounds that can be called vitamin B6 or it is a member of the family of B6 vitamins. Healthy human blood levels of pyridoxine are 2.1 - 21.7 ng/mL. Pyridoxine is readily converted to pyridoxal phosphate which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids and aminolevulinic acid. Pyridoxine assists in the balancing of sodium and potassium as well as promoting red blood cell production. Therefore pyridoxine is required by the body to make amino acids, carbohydrates, and lipids. It is linked to cancer immunity and helps fight the formation of homocysteine. It has been suggested that pyridoxine might help children with learning difficulties, and may also prevent dandruff, eczema, and psoriasis. In addition, pyridoxine can help balance hormonal changes in women and aid in immune system. Lack of pyridoxine may cause anemia, nerve damage, seizures, skin problems, and sores in the mouth (Wikipedia). Deficiency of pyridoxine, though rare because of widespread distribution in foods, leads to the development of peripheral neuritis in adults and affects the central nervous system in children (DOSE - 3rd edition). As a supplement pyridoxine is used to treat and prevent pyridoxine deficiency, sideroblastic anaemia, pyridoxine-dependent epilepsy, certain metabolic disorders, problems from isoniazid, and certain types of mushroom poisoning. Pyridoxine in combination with doxylamine is used as a treatment for morning sickness in pregnant women.

Propyl alcohol, also known as 1-propanol, n-propanol, or simply propanol, belongs to the class of organic compounds known as primary alcohols. Primary alcohols are compounds in which a hydroxy group is bonded to a primary carbon, with the general structure RCOH (R=alkyl, aryl). Propyl alcohol is a colourless, volatile liquid that is fully miscible with water. It has a sweet odour and an alcoholic, fermented, fusel taste. Propyl alcohol exists in all living species, ranging from bacteria to plants to humans. Propanol can be produced through fermentation of sugars by bacteria and yeast and small amounts are produced by gut microflora. Propanol has been identified as a fecal biomarker of Clostridium difficile infection (PMID: 30986230). When ingested, 1-propanol is metabolized by alcohol dehydrogenase to propionic acid leading to metabolic acidosis and an elevated anion gap (PMID: 18375643). It can be found in small amounts in alcoholic beverages such as wine. Industrially, the major use of 1-propanol is as a solvent as well as an intermediate in forming other industrially important compounds.  It is used as a carrier and extraction solvent for natural products, such as flavourings, vegetable oils, resins, waxes, and gums, and as a solvent for synthetic polymers, such as polyvinyl butyral, cellulose esters, lacquers, and PVC adhesives.  Other solvent applications include the use of 1-propanol in the polymerization and spinning of acrylonitrile, in flexographic printing inks, and in the dyeing of wool.  1-Propanol is used for both its solvent and antiseptic properties in drugs and cosmetics, such as lotions, soaps, and nail polishes (IPCS INCHEM, EHC 102). Both 1-propanol and 2-propanol are often used in hand disinfectants as they have excellent bactericidal activity.  1-Propanol is used less in industry than 2-propanol as it is more expensive and it is a toxicant that has a similar taste to ethanol, so 2-propanol is used as its unpleasant smell discourages abuse.
3-Hexanol, also known as fema 3351 or 3-hexyl alcohol, belongs to the class of organic compounds known as secondary alcohols.

Thiamylal is only found in individuals that have used or taken this drug. It is a barbiturate that is administered intravenously for the production of complete anesthesia of short duration, for the induction of general anesthesia, or for inducing a hypnotic state. (From Martindale, The Extra Pharmacopoeia, 30th ed, p919)Thiamylal binds at a distinct binding site associated with a Cl<sup>-</sup> ionopore at the GABA<sub>A</sub> receptor, increasing the duration of time for which the Cl<sup>-</sup> ionopore is open. The post-synaptic inhibitory effect of GABA in the thalamus is, therefore, prolonged.
beta-Sitosterol, a main dietary phytosterol found in plants, may have the potential for prevention and therapy for human cancer. Phytosterols are plant sterols found in foods such as oils, nuts, and vegetables. Phytosterols, in the same way as cholesterol, contain a double bond and are susceptible to oxidation, and are characterized by anti-carcinogenic and anti-atherogenic properties (PMID:13129445, 11432711). beta-Sitosterol is a phytopharmacological extract containing a mixture of phytosterols, with smaller amounts of other sterols, bonded with glucosides. These phytosterols are commonly derived from the South African star grass, Hypoxis rooperi, or from species of Pinus and Picea. The purported active constituent is termed beta-sitosterol. Additionally, the quantity of beta-sitosterol-beta-D-glucoside is often reported. Although the exact mechanism of action of beta-sitosterols is unknown, it may be related to cholesterol metabolism or anti-inflammatory effects (via interference with prostaglandin metabolism). Compared with placebo, beta-sitosterol improved urinary symptom scores and flow measures (PMID:10368239). A plant food-based diet modifies the serum beta-sitosterol concentration in hyperandrogenic postmenopausal women. This finding indicates that beta-sitosterol can be used as a biomarker of exposure in observational studies or as a compliance indicator in dietary intervention studies of cancer prevention (PMID:14652381). beta-Sitosterol induces apoptosis and activates key caspases in MDA-MB-231 human breast cancer cells (PMID:12579296).

Phenol, is a toxic, colourless crystalline solid with a sweet tarry odor that resembles a hospital smell. It is commonly used as an antiseptic and disinfectant. It is active against a wide range of micro-organisms including some fungi and viruses, but is only slowly effective against spores. It has been used to disinfect skin and to relieve itching. Phenol is also used in the preparation of cosmetics including sunscreens, hair dyes, and skin lightening preparations. It is also used in the production of drugs (it is the starting material in the industrial production of aspirin), weedkillers, and synthetic resins. Phenol can be found in areas with high levels of motor traffic, therefore, people living in crowded urban areas are frequently exposed to traffic-derived phenol vapor. The average (mean +/- SD) phenol concentration in urine among normal individuals living in urban areas is 7.4 +/- 2.2 mg/g of creatinine. Exposure of the skin to concentrated phenol solutions causes chemical burns which may be severe; in laboratories where it is used, it is usually recommended that polyethylene glycol solution is kept available for washing off splashes. Notwithstanding the effects of concentrated solutions, it is also used in cosmetic surgery as an exfoliant, to remove layers of dead skin (Wikipedia). In some bacteria phenol can be directly synthesized from tyrosine via the enzyme tyrosine phenol-lyase [EC:4.1.99.2]. It can be produced by Escherichia and Pseudomonas. Phenol has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821).

Desmosterol is an intermediate in the synthesis of cholesterol. Desmosterolosis is a rare autosomal recessive inborn errors of cholesterol synthesis that is caused by defective activity of desmosterol reductase which results in an accumulation of demosterol (DHCR24, EC 1.3.1.72), combines a severe osteosclerotic skeletal dysplasia and includes 2-3 toe syndactyly with Smith-Lemli-Opitz syndrome (SLOS; the biochemical block in SLOS results in decreased cholesterol levels and increased 7-dehydrocholesterol levels). Desmosterolosis is caused by mutation of the 24-dehydrocholesterol reductase gene (DHCR24). Many of the malformations in SLOS and desmosterolosis are consistent with impaired hedgehog function. The hedgehog proteins include Sonic hedgehog (SHH), which plays a major role in midline patterning and limb development. Desmosterolosis, caused by defective activity of desmosterol reductase, combines a severe osteosclerotic skeletal dysplasia. 7-dehydrocholesterol reductase (DHCR7, EC 1.3.1.21) reduces the C7-C8 double bond in the sterol B ring to form cholesterol or desmosterol depending upon the precursor. Desmosterol can be converted to cholesterol by DHCR24. Therefore, SLOS and Desmosterolosis patients invariably have elevated levels of cholesterol precursor's 7-dehydrocholesterol (and its spontaneous isomer 8-dehydrocholesterol) and absent desmosterol. (PMID: 14631207, 16207203).
Pyrocatechol, often known as catechol or benzene-1,2-diol, is a benzenediol, with formula C6H4(OH)2. It was first prepared in 1839 by H. Reinsch by distilling catechin (the juice of Mimosa catechu).

Its sulfonic acid is often present in the urine of many mammals. Small amounts of catechol occur naturally in fruits and vegetables, along with the enzyme polyphenol oxidase. Upon mixing the enzyme with the substrate and exposure to oxygen (as when a potato or apple is cut), the colorless catechol oxidizes to reddish-brown benzoquinone derivatives. The enzyme is inactivated by adding an acid, such as lemon juice, or by refrigeration. Excluding oxygen also prevents the browning reaction. Catechol melts at 28 °C and boils at 250 °C. It is employed in medicine as an expectorant. The dimethyl ether or veratrol is also used in medicine. Many other pyrocatechin derivatives have been suggested for therapeutic application.

Glycine is involved in the body's production of DNA, phospholipids and collagen, and in release of energy. Glycine levels are effectively measured in plasma in both normal patients and those with inborn errors of glycine metabolism. (http://www.dcnutrition.com/AminoAcids/) Nonketotic hyperglycinaemia (OMIM 606899) is an autosomal recessive condition caused by deficient enzyme activity of the glycine cleavage enzyme system (EC 2.1.1.10). The glycine cleavage enzyme system comprises four proteins: P-, T-, H- and L-proteins (EC 1.4.4.2, EC 2.1.2.10 and EC 1.8.1.4 for P-, T- and L-proteins). Mutations have been described in the GLDC (OMIM 238300), AMT (OMIM 238310), and GCSH (OMIM 238330) genes encoding the P-, T-, and H-proteins respectively. The glycine cleavage system catalyses the oxidative conversion of glycine into carbon dioxide and ammonia, with the remaining one-carbon unit transferred to folate as methylenetetrahydrofolate. It is the main catabolic pathway for glycine and it also contributes to one-carbon metabolism. Patients with a deficiency of this enzyme system have increased glycine in plasma, urine and cerebrospinal fluid (CSF) with an increased CSF: plasma glycine ratio. (PMID 16151895).

Methyl acetate, also known as acetic acid methyl ester or methyl ethanoate, is a clear, flammable liquid with a characteristic, not unpleasant smell like certain glues or nail polish removers. Methyl acetate has characteristics very similar to its analog ethyl acetate. Methyl acetate is used as a solvent in glues, paints, and nail polish removers, in chemical reactions, and for extractions. Methyl acetate is a non-polar (lipophilic) to weakly polar (hydrophilic) aprotic solvent. Methyl acetate has a solubility of 25% in water at room temperature. At elevated temperature its solubility in water is much higher. Methyl acetate is not stable in the presence of strong aqueous bases or acids. The conversion of methyl acetate back into its components, by an acid, is a first-order reaction with respect to the ester. The reaction of methyl acetate and a base, for example sodium hydroxide, is a second-order reaction with respect to both reactants

In medicine, mannitol is used as a diuretic and renal diagnostic aid. Mannitol has little significant energy value as it is largely eliminated from the body before any metabolism can take place. It can be used to treat oliguria associated with kidney failure or other manifestations of inadequate renal function and has been used for determination of glomerular filtration rate. Mannitol is also commonly used as a research tool in cell biological studies, usually to control osmolarity. Mannitol has a tendency to lose a hydrogen ion in aqueous solutions, which causes the solution to become acidic. For this, it is not uncommon to add a weak base, such as sodium bicarbonate, to the solution to adjust its pH. Mannitol is a non-permeating molecule i.e., it cannot cross biological membranes.

The major progestational steroid that is secreted primarily by the corpus luteum and the placenta. Progesterone acts on the uterus, the mammary glands and the brain. It is required in embryo implantation, pregnancy maintenance, and the development of mammary tissue for milk production. Progesterone, converted from pregnenolone, also serves as an intermediate in the biosynthesis of gonadal steroid hormones and adrenal corticosteroids. Progesterone is a C-21 steroid hormone involved in the female menstrual cycle, pregnancy (supports gestation) and embryogenesis of humans and other species. Progesterone belongs to a class of hormones called progestagens, and is the major naturally occurring human progestagen. During implantation and gestation, progesterone appears to decrease the maternal immune response to allow for the acceptance of the pregnancy. Progesterone decreases contractility of the uterine smooth muscle. The fetus metabolizes placental progesterone in the production of adrenal mineralo- and glucosteroids. A drop in progesterone levels is possibly one step that facilitates the onset of labor. In addition progesterone inhibits lactation during pregnancy. The fall in progesterone levels following delivery is one of the triggers for milk production. Progesterone is found to be associated with pregnene hydroxylation deficiency, which is an inborn error of metabolism.

It is a metabolite of diazepam, prazepam, temazepam, and clorazepate, and has moderate amnesic, anxiolytic, anticonvulsant, hypnotic, sedative, and skeletal muscle relaxant properties compared to other benzodiazepines (Wikipedia). Like other benzodiazepines, oxazepam exerts its anxiolytic effects by potentiating the effect of gamma-aminobutyric acid (GABA) on GABA-A receptors through a cooperative mechanism of action. GABA receptors are ionotropic chloride-linked channel receptors that produce inhibitory postsynaptic potentials. When activated by GABA, the GABA receptor/chloride ionophore complex undergoes a conformational change that allows the passage of chloride ions through the channel. Benzodiazepines are believed to exert their effect by increasing the effect of GABA at its receptor. Benzodiazepine binding increases chloride conductance in the presence of GABA by increasing the frequency at which the channel opens. In contrast, barbiturates increase chloride conductance in the presence of GABA by prolonging the time in which the channel remains open. There are 18 subtypes of the GABA receptor subunits. The &alpha;<sub>2</sub> subunit of the &alpha;<sub>2</sub>&beta;<sub>3</sub>&gamma;<sub>2</sub> receptor complex is thought to mediate anxiolytic effects while the &alpha;<sub>1</sub> subunit of the &alpha;<sub>1</sub>&beta;<sub>2</sub>&gamma;<sub>2</sub> receptor complex is thought to mediate sedative, anticonvulsant, and anterograde amnesia effects.

Cotinine is an alkaloid found in tobacco (Nicotiana tabacum). Cotinine belongs to the class of organic compounds known as pyrrolidinylpyridines. Pyrrolidinylpyridines are compounds containing a pyrrolidinylpyridine ring system, which consists of a pyrrolidine ring linked to a pyridine ring. It is also the predominant human metabolite of nicotine (when nicotine is inhaled or absorbed). In humans, about 70 to 80% of nicotine that is inhaled or absorbed is converted to cotinine. This transformation involves two steps. The first is mediated by a cytochrome P450 system (mainly CYP2A6 and CYP2B6) to produce nicotine iminium ion. The second step is catalyzed by aldehyde oxidase (AOX). A number of cotinine metabolites have also been structurally characterized. Indeed, it appears that most of the reported urinary metabolites of nicotine are derived from cotinine. Cotinine is widely used as a biomarker for exposure to tobacco smoke. Cotinine has an in vivo half-life of approximately 20 hours, and is typically detectable for several days (up to one week) after the use of tobacco. Similar to nicotine, cotinine binds to, activates, and desensitizes neuronal nicotinic acetylcholine receptors, though at much lower potency in comparison. It has demonstrated nootropic and antipsychotic-like effects in animal models. Cotinine treatment has also been shown to reduce depression, anxiety, and fear-related behavior as well as memory impairment in animal models of depression, PTSD, and Alzheimer's disease.

Squalene is an unsaturated aliphatic hydrocarbon (carotenoid) with six unconjugated double bonds found in human sebum (5%), fish liver oils, yeast lipids, and many vegetable oils (e.g. palm oil, cottonseed oil, rapeseed oil). Squalene is a volatile component of the scent material from Saguinus oedipus (cotton-top tamarin monkey) and Saguinus fuscicollis (saddle-back tamarin monkey) (Hawley's Condensed Chemical Reference). Squalene is a component of adult human sebum that is principally responsible for fixing fingerprints (ChemNetBase). It is a natural organic compound originally obtained for commercial purposes primarily from shark liver oil, though there are botanical sources as well, including rice bran, wheat germ, and olives. All higher organisms produce squalene, including humans. It is a hydrocarbon and a triterpene. Squalene is a biochemical precursor to the whole family of steroids. Oxidation of one of the terminal double bonds of squalene yields 2,3-squalene oxide which undergoes enzyme-catalyzed cyclization to afford lanosterol, which is then elaborated into cholesterol and other steroids. Squalene is a low-density compound often stored in the bodies of cartilaginous fishes such as sharks, which lack a swim bladder and must therefore reduce their body density with fats and oils. Squalene, which is stored mainly in the shark's liver, is lighter than water with a specific gravity of 0.855 (Wikipedia) Squalene is used as a bactericide. It is also an intermediate in the manufacture of pharmaceuticals, rubber chemicals, and colouring materials (Physical Constants of Chemical Substances).

Gamma-Elemene, also known as g-elemene, belongs to the class of organic compounds known as sesquiterpenoids. Sesquiterpenoids are terpenes that contain 15 carbon atoms and are comprised of three isoprene units. The biosynthesis of sesquiterpenes is known to occur mainly through the mevalonic acid pathway (MVA), in the cytosol. However, recent studies have found evidence of pathway crosstalk with the methyl-erythritol-phosphate (MEP) pathway in the cytosol. Farnesyl diphosphate (FPP) is a key intermediate in the biosynthesis of cyclic sesquiterpenes. FPP undergoes several cyclization reactions to yield a diverse number of cyclic arrangements. More formally, gamma-elemene is a cyclohexane substituted at positions 1, 1, 2, and 4 by methyl, vinyl, isopropenyl and isopropylidene groups, respectively. There are four known elemene isomers including ≈í¬±-, ≈í‚â§-, ≈í‚â•-, and ≈í¬•-elemene. The elemenes contribute to the floral aromas of some plants and are used as pheromones by some insects. Gamma-elemene is found in many essential plant oils including wormwood leaf oil, peppermint oil, pepper tree leaf oil, parsley leaf oil, orange peel oil, lime oil, juniper berry oil, hinoki leaf oil, angelica root oil, and angelica seed oil. Gamma-elemene has been shown to exhibit good insecticidal activity against the crop pest Spodoptera litura (tobacco cutworm or cotton leafworm) and could be useful as an eco-friendly biopesticide (PMID:28634795).

Amitriptyline hydrochloride is a dibenzocycloheptene-derivative tricyclic antidepressant (TCA). TCAs are structurally similar to phenothiazines. They contain a tricyclic ring system with an alkyl amine substituent on the central ring. In non-depressed individuals, amitriptyline does not affect mood or arousal, but may cause sedation. In depressed individuals, amitriptyline exerts a positive effect on mood. TCAs are potent inhibitors of serotonin and norepinephrine reuptake. Tertiary amine TCAs, such as amitriptyline, are more potent inhibitors of serotonin reuptake than secondary amine TCAs, such as nortriptyline. TCAs also down-regulate cerebral cortical &beta;-adrenergic receptors and sensitize post-synaptic serotonergic receptors with chronic use. The antidepressant effects of TCAs are thought to be due to an overall increase in serotonergic neurotransmission. TCAs also block histamine-H<sub>1</sub> receptors, &alpha;<sub>1</sub>-adrenergic receptors and muscarinic receptors, which accounts for their sedative, hypotensive and anticholinergic effects (e.g. blurred vision, dry mouth, constipation, urinary retention), respectively. See toxicity section below for a complete listing of side effects. Amitriptyline may be used to treat depression, chronic pain (unlabeled use), irritable bowel syndrome (unlabeled use), diabetic neuropathy (unlabeled use), post-traumatic stress disorder (unlabeled use), and for migraine prophylaxis (unlabeled use).

Benzaldehyde is occasionally found as a volatile component of urine. Benzaldehyde is an aromatic aldehyde used in cosmetics as a denaturant, a flavoring agent, and as a fragrance. Currently used in only seven cosmetic products, its highest reported concentration of use was 0.5% in perfumes. Benzaldehyde is a generally regarded as safe (GRAS) food additive in the United States and is accepted as a flavoring substance in the European Union. Because Benzaldehyde rapidly metabolizes to Benzoic Acid in the skin, the available dermal irritation and sensitization data demonstrating no adverse reactions to Benzoic Acid were considered supportive of the safety of Benzaldehyde. Benzaldehyde is absorbed through skin and by the lungs, distributes to all well-perfused organs, but does not accumulate in any specific tissue type. After being metabolized to benzoic acid, conjugates are formed with glycine or glucuronic acid, and excreted in the urine. Several studies have suggested that Benzaldehyde can have carcinostatic or antitumor properties. Overall, at the concentrations used in cosmetics, Benzaldehyde was not considered a carcinogenic risk to humans. Although there are limited irritation and sensitization data available for Benzaldehyde, the available dermal irritation and sensitization data and ultraviolet (UV) absorption and phototoxicity data demonstrating no adverse reactions to Benzoic Acid support the safety of Benzaldehyde as currently used in cosmetic products. (PMID:16835129, Int J Toxicol. 2006;25 Suppl 1:11-27.).

Diclofenac is only found in individuals that have used or taken this drug. It is a non-steroidal anti-inflammatory agent (NSAID) with antipyretic and analgesic actions. It is primarily available as the sodium salt. [PubChem]The antiinflammatory effects of diclofenac are believed to be due to inhibition of both leukocyte migration and the enzyme cylooxygenase (COX-1 and COX-2), leading to the peripheral inhibition of prostaglandin synthesis. As prostaglandins sensitize pain receptors, inhibition of their synthesis is responsible for the analgesic effects of diclofenac. Antipyretic effects may be due to action on the hypothalamus, resulting in peripheral dilation, increased cutaneous blood flow, and subsequent heat dissipation.
beta-Sitosterol, a main dietary phytosterol found in plants, may have the potential for prevention and therapy for human cancer. Phytosterols are plant sterols found in foods such as oils, nuts, and vegetables. Phytosterols, in the same way as cholesterol, contain a double bond and are susceptible to oxidation, and are characterized by anti-carcinogenic and anti-atherogenic properties (PMID:13129445, 11432711). beta-Sitosterol is a phytopharmacological extract containing a mixture of phytosterols, with smaller amounts of other sterols, bonded with glucosides. These phytosterols are commonly derived from the South African star grass, Hypoxis rooperi, or from species of Pinus and Picea. The purported active constituent is termed beta-sitosterol. Additionally, the quantity of beta-sitosterol-beta-D-glucoside is often reported. Although the exact mechanism of action of beta-sitosterols is unknown, it may be related to cholesterol metabolism or anti-inflammatory effects (via interference with prostaglandin metabolism). Compared with placebo, beta-sitosterol improved urinary symptom scores and flow measures (PMID:10368239). A plant food-based diet modifies the serum beta-sitosterol concentration in hyperandrogenic postmenopausal women. This finding indicates that beta-sitosterol can be used as a biomarker of exposure in observational studies or as a compliance indicator in dietary intervention studies of cancer prevention (PMID:14652381). beta-Sitosterol induces apoptosis and activates key caspases in MDA-MB-231 human breast cancer cells (PMID:12579296).

1-Octanol, also known as octan-1-ol, is the organic compound with the molecular formula CH3(CH2)7OH. It is a fatty alcohol. Many other isomers are also known generically as octanols. Octanol is mainly produced industrially by the oligomerization of ethylene using triethylaluminium followed by oxidation of the alkylaluminium products. This route is known as the Ziegler alcohol synthesis. Octanol also occurs naturally in the form of esters in some essential oils. Octanol and water are immiscible. The distribution of a compound between water and octanol is used to calculate the partition coefficient (logP) of that molecule. Water/octanol partitioning is a good approximation of the partitioning between the cytosol and lipid membranes of living systems. Octanol is a colorless, slightly viscous liquid used as a defoaming or wetting agent. It is also used as a solvent for protective coatings, waxes, and oils, and as a raw material for plasticizers. It is also one of many compounds derived from tobacco and tobacco smoke and shown to increase the permeability of the membranes of human lung fibroblasts (PMID 7466833).

Menadione is a synthetic naphthoquinone without the isoprenoid side chain and biological activity, but can be converted to active vitamin K2, menaquinone, after alkylation in vivo. -- Pubchem; Despite the fact that it can serve as a precursor to various types of vitamin K, menadione is generally not used as a nutritional supplement. Large doses of menadione have been reported to cause adverse outcomes including hemolytic anemia due to G6PD deficiency, neonatal brain or liver damage, or neonatal death in some cases. Moreover, menadione supplements have been banned by the FDA because of their high toxicity. It is sometimes called vitamin K3, although derivatives of naphthoquinone without the sidechain in the 3-position cannot exert all the functions of the K vitamins. Menadione is a vitamin precursor of K2 which utilizes alkylation in the liver to yield menaquinones (MK-n, n=1-13; K2 vitamers), and hence, is better classified as a provitamin. -- Wikipedia.

Naphthalene is found, on average, in the highest concentration within a few different foods, such as black walnuts, corns, and cloves. Naphthalene has also been detected, but not quantified, in several different foods, such as green bell peppers, orange bell peppers, rices, yellow bell peppers, and red bell peppers. This could make naphthalene a potential biomarker for the consumption of these foods. Naphthalene was once the primary ingredient in mothballs, though its use has largely been replaced in favor of alternatives such as 1,4-dichlorobenzene. Naphthalene is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Inhalation of naphthalene vapor has been associated with headaches, nausea, vomiting and dizziness. Naphthalene is the most abundant single component of coal tar so most of it is now industrially derived from coal tar. Aside from coal tar, trace amounts of naphthalene are produced by magnolias and some species of deer, as well as the Formosan subterranean termite, possibly produced by the termite as a repellant against "ants, poisonous fungi and nematode worms."[23] Some strains of the endophytic fungus Muscodor albus produce naphthalene among a range of volatile organic compounds, while Muscodor vitigenus produces naphthalene almost exclusively (PMID:12427963).

Hippuric acid is an acyl glycine formed from the conjugation of benzoic acid with glycine. Acyl glycines are produced through the action of glycine N-acyltransferase (EC 2.3.1.13) which is an enzyme that catalyzes the chemical reaction: acyl-CoA + glycine < -- > CoA + N-acylglycine. Hippuric acid is a normal component of urine and is typically increased with increased consumption of phenolic compounds (tea, wine, fruit juices). These phenols are converted into benzoic acid which is then converted into hippuric acid and excreted in the urine. Hippuric acid is the most frequently used biomarker in the biological monitoring of occupational exposure to toluene. This product of solvent biotransformation may be also found in the urine of individuals who have not been exposed to the solvent. A smaller fraction of the absorbed toluene is oxidized into aromatic compounds including ortho-cresol, which is not found in the urine of nonexposed individuals in a significant amount. The concentration of hippuric acid in the urine of individuals exposed to a low toluene concentration does not differ from that of individuals not exposed to the solvent. This has led to the conclusion that hippuric acid should not be utilized in the biological monitoring of occupational exposure to low levels of toluene in the air. Protein-bound organic acids such as hippuric acid are markedly accumulated in uremic plasma and produce defective protein binding of drugs (PMID: 9120876 , 8734460). Hippuric acid has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821). Hippuric acid is also found to be associated with phenylketonuria, propionic acidemia, and tyrosinemia I, which are inborn errors of metabolism. Hippuric acid is an endogenous phenolic acid metabolite detected after the consumption of whole grain.

Androstenedione is a delta-4 19-carbon steroid that is produced not only in the testis, but also in the ovary and the adrenal cortex. Depending on the tissue type, androstenedione can serve as a precursor to testosterone as well as estrone and estradiol. It is the common precursor of male and female sex hormones. Some androstenedione is also secreted into the plasma and may be converted in peripheral tissues to testosterone and estrogens. Androstenedione originates either from the conversion of dehydroepiandrosterone or from 17-hydroxyprogesterone. It is further converted to either testosterone or estrone. The production of adrenal androstenedione is governed by ACTH, while the production of gonadal androstenedione is under control by gonadotropins.

Biologically, ethanolamine is an initial precursor for the biosynthesis of two primary phospholipid classes, phosphatidylcholine (PC) and phosphatidylethanolamine (PE). In this regard, ethanolamine is the second-most-abundant head group for phospholipids. Ethanolamine serves as a precursor for a variety of N-acylethanolamines (NAEs). These are molecules that modulate several animal and plant physiological processes such as seed germination, plant‚Äìpathogen interactions, chloroplast development and flowering (PMID: 30190434). Ethanolamine, when combined with arachidonic acid (C20H32O2; 20:4, œâ-6), can also form the endocannabinoid anandamide. Ethanolamine can be converted to phosphoethanolamine via the enzyme known as ethanolamine kinase. the two substrates of this enzyme are ATP and ethanolamine, whereas its two products are ADP and O-phosphoethanolamine. In most plants ethanolamine is biosynthesized by decarboxylation of serine via a pyridoxal 5'-phosphate-dependent l-serine decarboxylase (SDC). Ethanolamine exists in all living species, ranging from bacteria to plants to humans. Ethanolamine has been detected, but not quantified in, several different foods, such as narrowleaf cattails, mung beans, blackcurrants, white cabbages, and bilberries.

11-Deoxycorticosterone (also called desoxycortone, 21-hydroxyprogesterone, DOC, or simply deoxycorticosterone) is a steroid hormone produced by the adrenal gland that possesses mineralocorticoid activity and acts as a precursor to aldosterone. It is classified as a member of the 21-hydroxysteroids. 21-hydroxysteroids are steroids carrying a hydroxyl group at the 21-position of the steroid backbone. Deoxycorticosterone is very hydrophobic, practically insoluble (in water), and relatively neutral. Deoxycorticosterone can be synthesized from progesterone by 21-beta-hydroxylase and is then converted to corticosterone by 11-beta-hydroxylase. Corticosterone is then converted to aldosterone by aldosterone synthase. Deoxycorticosterone stimulates the collecting tubules in the kidney to continue to excrete potassium in much the same way that aldosterone does. Deoxycorticosterone has about 1/20 of the sodium retaining power of aldosterone and about 1/5 the potassium excreting power of aldosterone (Wikipedia). Deoxycorticosterone can be found throughout all human tissues and has been detected in amniotic fluid and blood. When present in sufficiently high levels, deoxycorticosterone can act as a hypertensive agent and a metabotoxin. A hypertensive agent increases blood pressure and causes the production of more urine. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels.  Chronically high levels of deoxycorticosterone are associated with congenital adrenal hyperplasia (CAH) and with adrenal tumors producing deoxycorticosterone (PMID: 20671982). High levels of this mineralocorticoid are associated with resistant hypertension, which can result in polyuria, polydipsia, increased blood volume, edema, and cardiac enlargement. Deoxycorticosterone can be used to treat adrenal insufficiency. In particular, desoxycorticosterone acetate (DOCA) is used as replacement therapy in Addison's disease.

Trimethadione is only found in individuals that have used or taken this drug. It is an anticonvulsant effective in absence seizures, but generally reserved for refractory cases because of its toxicity. (From AMA Drug Evaluations Annual, 1994, p378)Trimethadione reduces T-type calcium currents in thalamic neurons, including thalamic relay neurons. It does so via the inhibition of voltage dependent T-type calcium channels. This raises the threshold for repetitive activity in the thalamus, and inhibits corticothalamic transmission. Thus, the abnormal thalamocortical rhythmicity, which is thought to underlie the 3-Hz spike-and-wave discharge seen on electroencephalogram(EEG) with absence seizures, is dampened.

delta-Hexanolactone is the lactone of 5-hydroxyhexanoic acid. Lactones are internal esters that exist in equilibrium between their closed (lactone) and open (hydroxy acid) forms in an aqueous environment. The lactone/hydroxy acid ratio at equilibrium is pH-dependent, with the closed form being favored at lower pH values, and can be greatly influenced by structural features of the lactone such as the ring size, substituents on the ring and the presence of double bonds within the ring. Many drugs and endogenous compounds are lactones or hydroxy acids and an enzyme capable of catalyzing the interchange between the open and closed forms in vivo could have pronounced effects upon their biological activity and/or distribution. delta-Hexanolactone is the substrate of paraoxonases (PON) in humans.

Stigmasterol is a phytosterol, meaning it is steroid derived from plants. As a food additive, phytosterols have cholesterol-lowering properties (reducing cholesterol absorption in intestines), and may act in cancer prevention. Phytosterols naturally occur in small amount in vegetable oils, especially soybean oil. One such phytosterol complex, isolated from vegetable oil, is cholestatin, composed of campesterol, stigmasterol, and brassicasterol, and is marketed as a dietary supplement. Sterols can reduce cholesterol in human subjects by up to 15%. The mechanism behind phytosterols and the lowering of cholesterol occurs as follows : the incorporation of cholesterol into micelles in the gastrointestinal tract is inhibited, decreasing the overall amount of cholesterol absorbed. This may in turn help to control body total cholesterol levels, as well as modify HDL, LDL and TAG levels. Many margarines, butters, breakfast cereals and spreads are now enriched with phytosterols and marketed towards people with high cholesterol and a wish to lower it. Stigmasterol is found to be associated with phytosterolemia, which is an inborn error of metabolism.

The conversion of the natural C19 steroids, testosterone and androstenedione into estrone is dependent on a complex key reaction catalyzed by the cytochrome P450 aromatase (EC 1.14.14.1, unspecific monooxygenase), which is expressed in many tissues of the adult human (e.g. ovary, fat tissue), but not in the liver. The ovaries after menopause continue to produce androstenedione and testosterone in significant amounts and these androgens are converted in fat, muscle, and skin into estrone. When women between the ages of 45 and 64 years have prophylactic oophorectomy (when hysterectomy is performed for benign disease to prevent the development of ovarian cancer), evidence suggests that oophorectomy increases the subsequent risk of coronary heart disease (CHD) and osteoporosis. Whereas 14,000 women die of ovarian cancer every year nearly 490,000 women die of heart disease and 48,000 women die within 1 year after hip fracture. Therefore, the decision to perform prophylactic oophorectomy should be approached with great caution for the majority of women who are at low risk of developing ovarian cancer. Steroid sulfatase (EC 3.1.6.2, STS) hydrolyzes steroid sulfates, such as estrone sulfate to estrone which can be converted to steroids with potent estrogenic properties, that is, estradiol; STS activity is much higher in breast tumors and high levels of STS mRNA expression in tumors are associated with a poor prognosis. The biological roles of estrogens in tumorigenesis are certainly different between the endometrium and breast, although both are considered "estrogen-dependent tissues". 17beta-hydroxysteroid dehydrogenases (EC 1.1.1.62, 17-HSDs) are enzymes involved in the formation of active sex steroids. estrone is interconverted by two enzymes 17-HSD types. Type 1 converts estrone to estradiol and Type 2 catalyzes the reverse reaction. (PMID: 17653961, 17513923, 17470679, 17464097).
Tyramine is a monoamine compound derived from the amino acid tyrosine. Tyramine is metabolized by the enzyme monoamine oxidase. In foods, it is often produced by the decarboxylation of tyrosine during fermentation or decay. Foods containing considerable amounts of tyramine include fish, chocolate, alcoholic beverages, cheese, soy sauce, sauerkraut, and processed meat. A large dietary intake of tyramine can cause an increase in systolic blood pressure of 30 mmHg or more. Tyramine acts as a neurotransmitter via a G protein-coupled receptor with high affinity for tyramine called TA1. The TA1 receptor is found in the brain as well as peripheral tissues including the kidney. An indirect sympathomimetic, Tyramine can also serve as a substrate for adrenergic uptake systems and monoamine oxidase so it prolongs the actions of adrenergic transmitters. It also provokes transmitter release from adrenergic terminals. Tyramine is a biomarker for the consumption of cheese
Benzocaine is a surface anesthetic that acts by preventing transmission of impulses along nerve fibers and at nerve endings. Benzocaine is a local anesthetic commonly used as a topical pain reliever. It is the active ingredient in many over-the-counter analgesic ointments. Benzocaine is an ester, a compound made from the organic acid PABA (para-aminobenzoic acid) and ethanol. The process in which this ester is created is known as Fischer esterification.
Benzoic acid, C6H5COOH, is a colourless crystalline solid and the simplest aromatic carboxylic acid.

Tetrahydrofuran (THF) is a cyclic ether. It is a colorless, water-miscible organic liquid with low viscosity and a smell similar to diethyl ether. At low concentrations it has a faint, fruity aroma. It is one of the most polar ethers. THF is naturally present in coffee aroma, floured chickpeas, and cooked chicken. It is used in the manufacture of polymers as well as agricultural, pharmaceutical, and commodity chemicals. Because of its widespread use (industrially) and its presence in many foods, THF is a contaminant of exposure and can appear in human biofluids. THF oxidizes readily, which can lead to instability and result in cytotoxicity. In chemical synthesis applications, THF is often used for hydroborations used to synthesize primary alcohols. THF is frequently used as a solvent for Grignard reagents because of the oxygen atom's ability to coordinate to the magnesium ion component of the Grignard reagent (an organometallic chemical reaction involving alkyl- or aryl-magnesium halides). THF is often used in polymer science. For example, it can be used to dissolve rubber prior to determining its molecular mass using gel permeation chromatography. THF tends to form peroxides on storage in air. (PMID: 16999122, 12742700, 14619948). THF can be degraded by certain strains of Rhodococcus bacteria (PMID: 19230656).

Pyruvic acid or pyruvate is a simple alpha-keto acid. It is a three-carbon molecule containing a carboxylic acid group and a ketone functional group. Pyruvate is the simplest alpha-keto acid and according to official nomenclature by IUPAC, it is called alpha-keto propanoic acid. Like other keto acids, pyruvic acid can tautomerize from its ketone form to its enol form, containing a double bond and an alcohol. Pyruvate is found in all living organisms ranging from bacteria to plants to humans. It is intermediate compound in the metabolism of carbohydrates, proteins, and fats. Pyruvate is a key intermediate in several metabolic pathways throughout the cell. In particular, pyruvic acid can be made from glucose through glycolysis, converted back to carbohydrates (such as glucose) via gluconeogenesis, or to fatty acids through a reaction with acetyl-CoA. Pyruvic acid supplies energy to cells through the citric acid cycle (TCA or Krebs cycle) when oxygen is present (aerobic respiration), and alternatively ferments to produce lactate when oxygen is lacking (lactic acid). In glycolysis, phosphoenolpyruvate (PEP) is converted to pyruvate by pyruvate kinase. This reaction is strongly exergonic and irreversible. In gluconeogenesis, it takes two enzymes, pyruvate carboxylase and PEP carboxykinase, to catalyze the reverse transformation of pyruvate to PEP. Pyruvic acid is also a metabolite of Corynebacterium (PMID: 27872963).

Phenyl acetate (or phenylacetate) is a carboxylic acid ester that has been found in the biofluids of patients with nephritis and/or hepatitis as well as patients with phenylketonuria (PKU), an inborn error of metabolism. Phenyl acetate has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821). Excess phenylalanine in the body can be disposed of through a transamination process leading to the production of phenylpyruvate. The phenylpyruvate can be further metabolized into a number of products. Decarboxylation of phenylpyruvate gives phenylacetate, while a reduction reaction gives phenyllactate. The phenylacetate can be further conjugated with glutamine to give phenylacetyl glutamine. All of these metabolites can be detected in serum and urine of PKU patients. Phenyl acetate is also produced endogenously as the metabolite of 2-Phenylethylamine, which is mainly metabolized by monoamine oxidase to form phenyl acetate. 2-phenylethylamine is an "endogenous amphetamine" which may modulate central adrenergic functions, and the urinary phenyl acetate levels have been postulated as a marker for depression.

Propyl alcohol, also known as 1-propanol, n-propanol, or simply propanol, belongs to the class of organic compounds known as primary alcohols. Primary alcohols are compounds in which a hydroxy group is bonded to a primary carbon, with the general structure RCOH (R=alkyl, aryl). Propyl alcohol is a colourless, volatile liquid that is fully miscible with water. It has a sweet odour and an alcoholic, fermented, fusel taste. Propyl alcohol exists in all living species, ranging from bacteria to plants to humans. Propanol can be produced through fermentation of sugars by bacteria and yeast and small amounts are produced by gut microflora. Propanol has been identified as a fecal biomarker of Clostridium difficile infection (PMID: 30986230). When ingested, 1-propanol is metabolized by alcohol dehydrogenase to propionic acid leading to metabolic acidosis and an elevated anion gap (PMID: 18375643). It can be found in small amounts in alcoholic beverages such as wine. Industrially, the major use of 1-propanol is as a solvent as well as an intermediate in forming other industrially important compounds.  It is used as a carrier and extraction solvent for natural products, such as flavourings, vegetable oils, resins, waxes, and gums, and as a solvent for synthetic polymers, such as polyvinyl butyral, cellulose esters, lacquers, and PVC adhesives.  Other solvent applications include the use of 1-propanol in the polymerization and spinning of acrylonitrile, in flexographic printing inks, and in the dyeing of wool.  1-Propanol is used for both its solvent and antiseptic properties in drugs and cosmetics, such as lotions, soaps, and nail polishes (IPCS INCHEM, EHC 102). Both 1-propanol and 2-propanol are often used in hand disinfectants as they have excellent bactericidal activity.  1-Propanol is used less in industry than 2-propanol as it is more expensive and it is a toxicant that has a similar taste to ethanol, so 2-propanol is used as its unpleasant smell discourages abuse.
Isopropyl 2-methylpropanoate is found in pineapple. Isopropyl 2-methylpropanoate is used in fruit flavouring.
Phenol, is a toxic, colourless crystalline solid with a sweet tarry odor that resembles a hospital smell. It is commonly used as an antiseptic and disinfectant. It is active against a wide range of micro-organisms including some fungi and viruses, but is only slowly effective against spores. It has been used to disinfect skin and to relieve itching. Phenol is also used in the preparation of cosmetics including sunscreens, hair dyes, and skin lightening preparations. It is also used in the production of drugs (it is the starting material in the industrial production of aspirin), weedkillers, and synthetic resins. Phenol can be found in areas with high levels of motor traffic, therefore, people living in crowded urban areas are frequently exposed to traffic-derived phenol vapor. The average (mean +/- SD) phenol concentration in urine among normal individuals living in urban areas is 7.4 +/- 2.2 mg/g of creatinine. Exposure of the skin to concentrated phenol solutions causes chemical burns which may be severe; in laboratories where it is used, it is usually recommended that polyethylene glycol solution is kept available for washing off splashes. Notwithstanding the effects of concentrated solutions, it is also used in cosmetic surgery as an exfoliant, to remove layers of dead skin (Wikipedia). In some bacteria phenol can be directly synthesized from tyrosine via the enzyme tyrosine phenol-lyase [EC:4.1.99.2]. It can be produced by Escherichia and Pseudomonas. Phenol has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821).

This colourless crystalline solid is used in peptide synthesis. It is well known to form hydrogen bonded structures somewhat related to the base-pairing mechanism found in RNA and DNA. It is also a classic case of a molecule that exists as tautomers. Some publications only focus one of the two possible patterns, and neglect the influence of the other. For example, to calculation of the energy difference of the two tautomers in a non-polar solution will lead to a wrong result if a large quantity of the substance is on the side of the dimer in an equilibrium. The direct tautomerisation is not energetically favoured, but a dimerisation followed by a double proton transfer and dissociation of the dimer is a self catalytic path from one tautomer to the other. Protic solvents also mediate the proton transfer during the tautomerisation.

17a-Hydroxypregnenolone is a 21-carbon steroid that is converted from pregnenolone by cytochrome P450 17alpha hydroxylase/C17,20 lyase (CYP17, EC 1.14.99.9). 17a-Hydroxypregnenolone is an intermediate in the delta-5 pathway of biosynthesis of gonadal steroid hormones and the adrenal corticosteroids. The first, rate-limiting and hormonally regulated step in the biosynthesis of all steroid hormones is the conversion of cholesterol to pregnenolone. The conversion of cholesterol to pregnenolone is accomplished by the cleavage of the cholesterol side chain, catalyzed by a mitochondrial cytochrome P450 enzyme termed P450scc where scc designates Side Chain Cleavage. All steroid hormones are made from the pregnenolone produced by P450scc; thus, the presence or absence of each of the activities of CYP17 directs this pregnenolone towards its final metabolic pathway. While all cytochrome P450 enzymes can catalyze multiple reactions on a single active site, CYP17 is the only one described to date in which these multiple activities are differentially regulated by a physiologic process. 17a-Hydroxypregnenolone is converted to dehydroepiandrosterone by the 17,20 lyase activity of CYP17. The ratio of the 17,20 lyase to 17 alpha-hydroxylase activity of CYP17 determines the ratio of C21 to C19 steroids produced. This ratio is regulated post-translationally by at least three factors: the abundance of the electron-donating protein P450 oxidoreductase, the presence of cytochrome b5, and the serine phosphorylation of CYP17.

Bromodichloromethane, also known as dichlorobromomethane or monobromodichloromethane, is classified as a member of the trihalomethanes. Trihalomethanes are organic compounds in which exactly three of the four hydrogen atoms of methane (CH4) are replaced by halogen atoms. Bromodichloromethane is a colorless, nonflammable liquid. Small amounts are formed naturally by algae in the oceans. Some of it will dissolve in water, but it readily evaporates into air. Only small quantities of bromodichloromethane are produced in the United States. The small quantities that are produced are used in laboratories or to make other chemicals. However, most bromodichloromethane is formed as a by-product when chlorine is added to drinking water to kill bacteria. Bromodichloromethane has been formerly used as a flame retardant, and a solvent for fats and waxes and because of its high density for mineral separation. Now it is only used as a reagent or intermediate in organic chemistry. Bromodichloromethane can also occur in municipally-treated drinking water as a by-product of the chlorine disinfection process.

Naphthalenes are compounds containing a naphthalene moiety, which consists of two fused benzene rings. Naphthalene is possibly neutral. Naphthalene is a dry, pungent, and tar tasting compound. Naphthalene is found, on average, in the highest concentration within a few different foods, such as black walnuts, corns, and cloves. Naphthalene has also been detected, but not quantified, in several different foods, such as green bell peppers, orange bell peppers, rices, yellow bell peppers, and red bell peppers. This could make naphthalene a potential biomarker for the consumption of these foods. Naphthalene was once the primary ingredient in mothballs, though its use has largely been replaced in favor of alternatives such as 1,4-dichlorobenzene. Naphthalene is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Inhalation of naphthalene vapor has been associated with headaches, nausea, vomiting and dizziness. Naphthalene is the most abundant single component of coal tar so most of it is now industrially derived from coal tar. Aside from coal tar, trace amounts of naphthalene are produced by magnolias and some species of deer, as well as the Formosan subterranean termite, possibly produced by the termite as a repellant against "ants, poisonous fungi and nematode worms."[23] Some strains of the endophytic fungus Muscodor albus produce naphthalene among a range of volatile organic compounds, while Muscodor vitigenus produces naphthalene almost exclusively (PMID:12427963).

Indole is an aromatic heterocyclic organic compound. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing pyrrole ring. The participation of the nitrogen lone electron pair in the aromatic ring means that indole is not a base, and it does not behave like a simple amine. Indole is a microbial metabolite and it can be produced by bacteria as a degradation product of the amino acid tryptophan. It occurs naturally in human feces and has an intense fecal smell. At very low concentrations, however, indole has a flowery smell and is a constituent of many flower scents (such as orange blossoms) and perfumes. As a volatile organic compound, indole has been identified as a fecal biomarker of Clostridium difficile infection (PMID: 30986230). Natural jasmine oil, used in the perfume industry, contains around 2.5% of indole. Indole also occurs in coal tar. Indole has been found to be produced in a number of bacterial genera including Alcaligenes, Aspergillus, Escherichia, and Pseudomonas (PMID: 23194589, 2310183, 9680309). Indole plays a role in bacterial biofilm formation, bacterial motility, bacterial virulence, plasmid stability, and antibiotic resistance. It also functions as an intercellular signalling molecule (PMID: 26115989). Recently, it was determined that the bacterial membrane-bound histidine sensor kinase (HK) known as CpxA acts as a bacterial indole sensor to facilitate signalling (PMID: 31164470). It has been found that decreased indole concentrations in the gut promote bacterial pathogenesis, while increased levels of indole in the gut decrease bacterial virulence gene expression (PMID: 31164470). As a result, enteric pathogens sense a gradient of indole concentrations in the gut to migrate to different niches and successfully establish an infection.
11-Ketoetiocholanolone is an endogenous anabolic androgenic steroid. The concentration ratio of 11&#61538;-hydroxyetiocholanolone/11&#61538;-hydroxyandrosterone is increased in patients with uterine leiomyomas, and it appears to be caused by a decrease in patients' metabolite of steroids. The concentration of 11-Ketoetiocholanolone is significantly higher in these patients. There is a relationship between urinary endogenous steroid metabolites and lower urinary tract function related to the residual volume in uroflowmetry in postmenopausal women. (PMID: 15808004, 14698830, 12728469).

Chlordiazepoxide is only found in individuals that have used or taken this drug. It is an anxiolytic benzodiazepine derivative with anticonvulsant, sedative, and amnesic properties. It has also been used in the symptomatic treatment of alcohol withdrawal. [PubChem]Chlordiazepoxide binds to stereospecific benzodiazepine (BZD) binding sites on GABA (A) receptor complexes at several sites within the central nervous system, including the limbic system and reticular formation. This results in an increased binding of the inhibitory neurotransmitter GABA to the GABA(A) receptor.BZDs, therefore, enhance GABA-mediated chloride influx through GABA receptor channels, causing membrane hyperpolarization. The net neuro-inhibitory effects result in the observed sedative, hypnotic, anxiolytic, and muscle relaxant properties.

Estrone is a major mammalian estrogen. The conversion of the natural C19 steroids, testosterone and androstenedione into estrone is dependent on a complex key reaction catalyzed by the cytochrome P450 aromatase (EC 1.14.14.1, unspecific monooxygenase), which is expressed in many tissues of the adult human (e.g. ovary, fat tissue), but not in the liver. The ovaries after menopause continue to produce androstenedione and testosterone in significant amounts and these androgens are converted in fat, muscle, and skin into estrone. When women between the ages of 45 and 64 years have prophylactic oophorectomy (when hysterectomy is performed for benign disease to prevent the development of ovarian cancer), evidence suggests that oophorectomy increases the subsequent risk of coronary heart disease (CHD) and osteoporosis. Whereas 14,000 women die of ovarian cancer every year nearly 490,000 women die of heart disease and 48,000 women die within 1 year after hip fracture. Therefore, the decision to perform prophylactic oophorectomy should be approached with great caution for the majority of women who are at low risk of developing ovarian cancer. Steroid sulfatase (EC 3.1.6.2, STS) hydrolyzes steroid sulfates, such as estrone sulfate to estrone which can be converted to steroids with potent estrogenic properties, that is, estradiol; STS activity is much higher in breast tumors and high levels of STS mRNA expression in tumors are associated with a poor prognosis. The biological roles of estrogens in tumorigenesis are certainly different between the endometrium and breast, although both are considered "estrogen-dependent tissues". 17beta-hydroxysteroid dehydrogenases (EC 1.1.1.62, 17-HSDs) are enzymes involved in the formation of active sex steroids. estrone is interconverted by two enzymes 17-HSD types. Type 1 converts estrone to estradiol and Type 2 catalyzes the reverse reaction. (PMID: 17653961, 17513923, 17470679, 17464097).
N-Acetylarylamine is an odourless solid chemical of leaf or flake-like appearance.

Environmental pollutant arising from the degradation of nonionic surfactants in sewage Nonoxynol-9, one of the APEs, is used as a surfactant in cleaning and cosmetic products, and as a spermicide in contraceptives. Nonylphenol is an organic compound of the wider family of alkylphenols. It is a product of industrial synthesis formed during the alkylation process of phenols, particularly in the synthesis of polyethoxylate detergents. Because of their man-made origins, nonylphenols are classified as xenobiotics. In nonylphenols, a hydrocarbon chain of nine carbon atoms is attached to the phenol ring in either the ortho (2), meta (3), or para (4) position, with the most common ring isomers being ortho or para (e.g. figure 1 para-nonylphenol). Moreover, the alkyl chains can exist as either linear n-alkyl chains, or complex branched chains. Nonylphenol is commonly obtained as a mixture of isomers, and is thus usually found as a pale yellow liquid at room temperature with a freezing point of -10Â°C and a boiling point of 295-320Â°C. However, pure isomers of nonylphenol crystallize readily at room temperatures and for example, para-n-nonylphenol, forms white crystals at room temperature. Nonylphenol, and a related compound tert-octylphenol, were first detected as an air pollutant in New York City and New Jersey, probably due to its evaporation from the Hudson river and other smaller rivers in the region that routinely receive municipal wastewaters. It is possible that the atmosphere is a destructive sink for nonylphenol as it is probably reactive with atmospheric radicals and/or is photoactive.

Approximately 95% of nitrobenzene is consumed in the production of aniline, which is a precursor to rubber chemicals, pesticides, dyes, explosives, and pharmaceuticals. Nitrobenzene is an organic compound with the chemical formula C6H5NO2. It is a water-insoluble pale yellow oil with an almond-like odor. It freezes to give greenish-yellow crystals. It is produced on a large scale from benzene as a precursor to aniline. In the laboratory, it is occasionally used as a solvent, especially for electrophilic reagents. Nitrobenzene is prepared by nitration of benzene with a mixture of concentrated sulfuric acid, water, and nitric acid. This mixture is sometimes called 'mixed acid.' The production of nitrobenzene is one of the most dangerous processes conducted in the chemical industry because of the exothermicity of the reaction ( delta H = 117 kJ/mol).
Nicotinic acid, also known as niacin or vitamin B3, is a water-soluble vitamin whose derivatives such as NADH, NAD, NAD+, and NADP play essential roles in energy metabolism in the living cell and DNA repair. The designation vitamin B3 also includes the amide form, nicotinamide or niacinamide. Severe lack of niacin causes the deficiency disease pellagra, whereas a mild deficiency slows down the metabolism decreasing cold tolerance. The recommended daily allowance of niacin is 2-12 mg a day for children, 14 mg a day for women, 16 mg a day for men, and 18 mg a day for pregnant or breast-feeding women. It is found in various animal and plant tissues and has pellagra-curative, vasodilating, and antilipemic properties. The liver can synthesize niacin from the essential amino acid tryptophan, but the synthesis is extremely slow and requires vitamin B6; 60 mg of tryptophan are required to make one milligram of niacin. Bacteria in the gut may also perform the conversion but are inefficient.

2-(2-Methylpropyl)thiazole is found in garden tomato. Tomato volatile and flavouring ingredient. Liq. with tomato leaf odou
1,1,1-Trichloroethane is generally considered as a polar solvent. Owing to its unsymmetrical structure, it is a superior solvent for organic compounds that do not dissolve well in hydrocarbons such as hexane. It is an excellent solvent for many organic materials and also one of the least toxic of the chlorinated hydrocarbons. Prior to the Montreal Protocol, it was widely used for cleaning metal parts and circuit boards, as a photoresist solvent in the electronics industry, as an aerosol propellant, as a cutting fluid additive, and as a solvent for inks, paints, adhesives and other coatings. 1,1,1-Trichloroethane is marketed with stabilizers since it is unstable with respect to dehydrochlorination and attacks some metals. Stabilizers comprise up to 8% of the formulation, including acid scavengers (epoxides, amines) and complexants. The Montreal Protocol targeted 1,1,1-trichloroethane as one of those compounds responsible for ozone depletion and banned its use beginning in 1996. Since then, its manufacture and use has been phased out throughout most of the world. The organic compound 1,1,1-trichloroethane, also known as methyl chloroform, is a chloroalkane.

Aniline is an organic chemical compound, specifically a primary aromatic amine. It consists of a benzene ring attached to an amino group. Aniline is oily and, although colorless, it can be slowly oxidized and resinified in air to form impurities which can give it a red-brown tint. Its boiling point is 184 degree centigrade and its melting point is -6 degree centegrade. It is a liquid at room temperature. Like most volatile amines, it possesses a somewhat unpleasant odour of rotten fish, and also has a burning aromatic taste; it is a highly acrid poison. It ignites readily, burning with a large smoky flame. Aniline reacts with strong acids to form salts containing the anilinium (or phenylammonium) ion (C6H5-NH3+), and reacts with acyl halides (such as acetyl chloride (ethanoyl chloride), CH3COCl) to form amides. The amides formed from aniline are sometimes called anilides, for example CH3-CO-NH-C6H5 is acetanilide, for which the modern name is N-phenyl ethanamide. Like phenols, aniline derivatives are highly reactive in electrophilic substitution reactions. For example, sulfonation of aniline produces sulfanilic acid, which can be converted to sulfanilamide. Sulfanilamide is one of the sulfa drugs which were widely used as antibacterial in the early 20th century. Aniline was first isolated from the destructive distillation of indigo in 1826 by Otto Unverdorben. In 1834, Friedrich Runge isolated from coal tar a substance which produced a beautiful blue color on treatment with chloride of lime; this he named kyanol or cyanol. In 1841, C. J. Fritzsche showed that by treating indigo with caustic potash it yielded an oil, which he named aniline, from the specific name of one of the indigo-yielding plants, Indigofera anil, anil being derived from the Sanskrit, dark-blue.

Niacinamide, also known as nicotinamide (NAM), is a form of vitamin B3 found in food and used as a dietary supplement and medication. Niacinamide belongs to the class of organic compounds known as nicotinamides. These are heterocyclic aromatic compounds containing a pyridine ring substituted at position 3 by a carboxamide group. Its primary significance is in the prevention and/or cure of blacktongue and pellagra. The structure of nicotinamide consists of a pyridine ring to which a primary amide group is attached in the meta position. It is an amide of nicotinic acid. As an aromatic compound, it undergoes electrophilic substitution reactions and transformations of its two functional groups. Niacinamide and phosphoribosyl pyrophosphate can be converted into nicotinic acid mononucleotide and phosphate by the enzyme nicotinamide phosphoribosyltransferase. In humans, niacinamide is involved in the metabolic disorder called the nad+ signalling pathway (cancer). Niacinamide is an odorless tasting compound. Outside of the human body, niacinamide is found, on average, in the highest concentration within a few different foods, such as common sages, cow milk, and cocoa beans and in a lower concentration in common pea. Niacinamide has also been detected, but not quantified in several different foods, such as yardlong beans, roselles, apples, oyster mushrooms, and swiss chards. Niacinamide occurs in trace amounts mainly in meat, fish, nuts, and mushrooms, as well as to a lesser extent in some vegetables. It is commonly added to cereals and other foods. Many multivitamins contain 20–30 mg of vitamin B3 and it is also available in higher doses. Most animals cannot manufacture this compound in amounts sufficient to prevent nutritional deficiency and it therefore must be supplemented through dietary intake.

Because it is not hygroscopic, ethyl acetate also keeps the insect soft enough to allow proper mounting suitable for a collection. In a killing jar charged with ethyl acetate, the vapors will kill the collected (usually adult) insect quickly without destroying it. In organic and in natural products chemistry ethyl acetate is often used as a solvent for reactions or extractions. Ethyl acetate is a potentially toxic compound. Ethyl acetate, with regard to humans, has been found to be associated with several diseases such as perillyl alcohol administration for cancer treatment, crohn's disease, nonalcoholic fatty liver disease, and pervasive developmental disorder not otherwise specified; ethyl acetate has also been linked to the inborn metabolic disorder celiac disease.

Sulfamethoxazole is only found in individuals that have used or taken this drug. It is a bacteriostatic antibacterial agent that interferes with folic acid synthesis in susceptible bacteria. Its broad spectrum of activity has been limited by the development of resistance. (From Martindale, The Extra Pharmacopoeia, 30th ed, p208)Sulfonamides inhibit the enzymatic conversion of pteridine and p-aminobenzoic acid (PABA) to dihydropteroic acid by competing with PABA for binding to dihydrofolate synthetase, an intermediate of tetrahydrofolic acid (THF) synthesis. THF is required for the synthesis of purines and dTMP and inhibition of its synthesis inhibits bacterial growth. Pyrimethamine and trimethoprim inhibit dihydrofolate reductase, another step in THF synthesis, and therefore act synergistically with the sulfonamides.

It is oxidized by chromic acid to isovaleraldehyde, and it forms crystalline addition compounds with calcium chloride and tin(IV) chloride. When pure, it is nontoxic, while the impure product is toxic.
The excellent tolerability of therapeutic doses of paracetamol (acetaminophen) is a major factor in the very wide use of the drug. The major problem in the use of paracetamol is its hepatotoxicity after an overdose. Hepatotoxicity has also been reported after therapeutic doses, but critical analysis indicates that most patients with alleged toxicity from therapeutic doses have taken overdoses. Importantly, prospective studies indicate that therapeutic doses of paracetamol are an unlikely cause of hepatotoxicity in patients who ingest moderate to large amounts of alcohol (PMID: 15733027). Single doses of paracetamol are effective analgesics for acute postoperative pain and give rise to few adverse effects (PMID: 14974073). Acetaminophen (AAP) overdose and the resulting hepatotoxicity is an important clinical problem. In addition, AAP is widely used as a prototype hepatotoxin to study mechanisms of chemical-induced cell injury and to test the hepatoprotective potential of new drugs and herbal medicines. Because of its importance, the mechanisms of AAP-induced liver cell injury have been extensively investigated and controversially discussed for many years (PMID: 16863451).

Urocanic acid (CAS: 104-98-3) is a breakdown (deamination) product of histidine. In the liver, urocanic acid is an intermediate in the conversion of histidine to glutamic acid, whereas, in the epidermis, it accumulates and may be both a UV protectant and an immunoregulator. Urocanic acid (UA) exists as a trans isomer (t-UA, approximately 30 mg/cm2) in the uppermost layer of the skin (stratum corneum). t-UA is formed as the cells of the second layer of the skin become metabolically inactive. During this process, proteins and membranes degrade, histidine is released, and histidase (histidine ammonia lyase) catalyzes the deamination of histidine to form t-UA. t-UA accumulates in the epidermis until removal by either the monthly skin renewal cycle or sweat. Upon absorption of UV light, the naturally occurring t-UA isomerizes to its cis form, c-UA. Because DNA lesions (e.g., pyrimidine dimers) in the lower epidermis can result from UV-B absorption, initial research proposed that t-UA acted as a natural sunscreen absorbing UV-B in the stratum corneum before the damaging rays could penetrate into lower epidermal zones. Researchers have found that c-UA also suppresses contact hypersensitivity and delayed hypersensitivity, reduces the Langerhans cell count in the epidermis, prolongs skin-graft survival time, and affects natural killer cell activity. (E)-Urocanic acid is found in mushrooms. It has been isolated from Coprinus atramentarius (common ink cap) and Phallus impudicus (common stinkhorn).

Naphthalene has also been detected, but not quantified, in several different foods, such as green bell peppers, orange bell peppers, rices, yellow bell peppers, and red bell peppers. This could make naphthalene a potential biomarker for the consumption of these foods. Naphthalene was once the primary ingredient in mothballs, though its use has largely been replaced in favor of alternatives such as 1,4-dichlorobenzene. Naphthalene is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Inhalation of naphthalene vapor has been associated with headaches, nausea, vomiting and dizziness. Naphthalene is the most abundant single component of coal tar so most of it is now industrially derived from coal tar. Aside from coal tar, trace amounts of naphthalene are produced by magnolias and some species of deer, as well as the Formosan subterranean termite, possibly produced by the termite as a repellant against "ants, poisonous fungi and nematode worms."[23] Some strains of the endophytic fungus Muscodor albus produce naphthalene among a range of volatile organic compounds, while Muscodor vitigenus produces naphthalene almost exclusively (PMID:12427963).

Dimethyl sulfoxide (DMSO) is a key dipolar aprotic solvent. It is less toxic than other members of this class: dimethylformamide, dimethylacetamide, N-methyl-2-pyrrolidone, HMPA. Dimethyl sulfoxide is the chemical compound (CH3)2SO. This colorless liquid is an important "dipolar aprotic solvent." It is readily miscible in a wide range of organic solvents as well as water. It has a distinctive property of penetrating the skin very readily, allowing the handler to taste it. Some describe it as an "oyster-like" taste, others claim it tastes like garlic. DMSO is also employed as a rinsing agent in the electronics industry and, in its deuterated form (DMSO-d6), is a useful solvent in NMR due to its ability to dissolve a wide range of chemical compounds and its minimal interference with the sample signals. In cryobiology DMSO has been used as a cryoprotectant and is still an important constituent of cryoprotectant vitrification mixtures used to preserve organs, tissues, and cell suspensions. It is particularly important in the freezing and long-term storage of embryonic stem cells and hematopoietic stem cell, which are often frozen in a mixture of 10% DMSO and 90% fetal calf serum. As part of an autologous bone marrow transplant the DMSO is re-infused along with the patient's own hematopoietic stem cell. Dimethyl sulfoxide is a by-product of wood pulping. One of the leading suppliers of DMSO is the Gaylord company in the USA. DMSO is frequently used as solvent in a number of chemical reactions. In particular it is an excellent reaction solvent for SN2 alkylations: it is possible to alkylate indoles with very high yields using potassium hydroxide as the base and a similar reaction also occurs with phenols. DMSO can be reacted with methyl iodide to form a sulfoxonium ion which can be reacted with sodium hydride to form a sulfur ylide. The methyl groups of DMSO are somewhat acidic in character (pKa=35) due to the stabilization of the resultant anions by the sulfoxide group.
Dimethyl fumarate is a fungal growth inhibitor for tomato juice Dimethyl fumarate is an ester and an , -unsaturated electrophilic compound, undergoing reactions typical to them. It is also a diene acceptor in the ordinary Diels-Alder reaction, where the reactivity of its vinylidenic bond is enchanced by the two electron-withdrawing ester groups. Due to the geometry of the starting ester, the Diels-Alder product will have a trans configuration. Dimethyl fumarate is used to treat psoriasis. It is a lipophilic, highly mobile molecule in human tissue. However, as an , -unsaturated ester, dimethyl fumarate reacts rapidly with the detoxifying agent glutathione by Michael addition. When administered orally, it does not survive long enough to be absorbed into blood

It is classified as a member of the 21-hydroxysteroids. 21-hydroxysteroids are steroids carrying a hydroxyl group at the 21-position of the steroid backbone. Deoxycorticosterone is very hydrophobic, practically insoluble (in water), and relatively neutral. Deoxycorticosterone can be synthesized from progesterone by 21-beta-hydroxylase and is then converted to corticosterone by 11-beta-hydroxylase. Corticosterone is then converted to aldosterone by aldosterone synthase. Deoxycorticosterone stimulates the collecting tubules in the kidney to continue to excrete potassium in much the same way that aldosterone does. Deoxycorticosterone has about 1/20 of the sodium retaining power of aldosterone and about 1/5 the potassium excreting power of aldosterone (Wikipedia). Deoxycorticosterone can be found throughout all human tissues and has been detected in amniotic fluid and blood. When present in sufficiently high levels, deoxycorticosterone can act as a hypertensive agent and a metabotoxin. A hypertensive agent increases blood pressure and causes the production of more urine. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels.  Chronically high levels of deoxycorticosterone are associated with congenital adrenal hyperplasia (CAH) and with adrenal tumors producing deoxycorticosterone (PMID: 20671982). High levels of this mineralocorticoid are associated with resistant hypertension, which can result in polyuria, polydipsia, increased blood volume, edema, and cardiac enlargement. Deoxycorticosterone can be used to treat adrenal insufficiency. In particular, desoxycorticosterone acetate (DOCA) is used as replacement therapy in Addison's disease.

Androsterone is an inactive breakdown metabolite of testosterone, the product of a reaction mediated by the enzyme oxidative 17beta-hydroxysteroid dehydrogenase (EC 1.1.1.51, 17beta-HSD). Androsterone can also be metabolized from other adrenal androgens such as dehydroepiandrosterone, dihydrotestosterone, or androstenedione, and is considered an inactive end product. However, it can be a physiological effector in its own right. Androsterone might be converted back to dihydrotestosterone. Humans (and other primates) are unique among mammals in having high levels of circulating androsterone glucuronide, a process that is the major role of uridine-diphospho-glucuronosyltransferase enzymes (EC 2.4.1.17, UGT) for glucuronidation of steroid metabolism in humans. Conjugation of androsterone is a pathway found in all vertebrates and it is widely recognized that the liver is a major site of glucuronidation. However, it is now clear that extrahepatic tissues are also involved in the conjugation of compounds to which these tissues are exposed. High levels of androsterone glucuronide found in the human prostate, breast cyst fluid, and ovary follicular fluid suggest that glucuronidation of 5alpha-reduced C19 steroids occurs in these tissues as well. In doping control, the ratio of androsterone/etiocholanolone provides valuable information that allows the assignment of a urine specimen to a particular person or the identification of urine samples with identical steroid profiles; this is particularly important to detect attempts of urine manipulation including urine alteration and substitution (PMID: 9188497, 17017935, 14643063, 12943709, 9699884, 17260133).

Pyrrolidinylpyridines are compounds containing a pyrrolidinylpyridine ring system, which consists of a pyrrolidine ring linked to a pyridine ring. It is also the predominant human metabolite of nicotine (when nicotine is inhaled or absorbed). In humans, about 70 to 80% of nicotine that is inhaled or absorbed is converted to cotinine. This transformation involves two steps. The first is mediated by a cytochrome P450 system (mainly CYP2A6 and CYP2B6) to produce nicotine iminium ion. The second step is catalyzed by aldehyde oxidase (AOX). A number of cotinine metabolites have also been structurally characterized. Indeed, it appears that most of the reported urinary metabolites of nicotine are derived from cotinine. Cotinine is widely used as a biomarker for exposure to tobacco smoke. Cotinine has an in vivo half-life of approximately 20 hours, and is typically detectable for several days (up to one week) after the use of tobacco. Similar to nicotine, cotinine binds to, activates, and desensitizes neuronal nicotinic acetylcholine receptors, though at much lower potency in comparison. It has demonstrated nootropic and antipsychotic-like effects in animal models. Cotinine treatment has also been shown to reduce depression, anxiety, and fear-related behavior as well as memory impairment in animal models of depression, PTSD, and Alzheimer's disease.

Rutin is a flavonoid known to have a variety of biological activities including antiallergic, anti-inflammatory, antiproliferative, and anticarcinogenic properties. A large number of flavonoids, mostly O-glycosides, are polyphenolic compounds of natural origin that are present in most fruits and vegetables. The average intake of the compounds by humans on a normal diet is more than 1 g per day. Although flavonoids are devoid of classical nutritional value, they are increasingly viewed as beneficial dietary components that act as potential protectors against human diseases such as coronary heart disease, cancers, and inflammatory bowel disease. Rutin acts as a quercetin deliverer to the large intestine; moreover, quercetin is extensively metabolized in the large intestine, which suggests that quercetin liberated from rutin and/or its colonic metabolites may play a role. Rutin's anti-inflammatory actions are mediated through a molecular mechanism that underlies the quercetin-mediated therapeutic effects: quercetin-mediated inhibition of tumor necrosis factor-alpha (TNF-alpha)-induced nuclear factor kappa B (NFkB) activation. TNF-alpha-induced NFkB activity plays a central role in the production of pro-inflammatory mediators involved in progression of gut inflammation. (PMID:16132362).

Indole is an aromatic heterocyclic organic compound. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing pyrrole ring. The participation of the nitrogen lone electron pair in the aromatic ring means that indole is not a base, and it does not behave like a simple amine. Indole is a microbial metabolite and it can be produced by bacteria as a degradation product of the amino acid tryptophan. It occurs naturally in human feces and has an intense fecal smell. At very low concentrations, however, indole has a flowery smell and is a constituent of many flower scents (such as orange blossoms) and perfumes. As a volatile organic compound, indole has been identified as a fecal biomarker of Clostridium difficile infection (PMID: 30986230). Natural jasmine oil, used in the perfume industry, contains around 2.5% of indole. Indole also occurs in coal tar. Indole has been found to be produced in a number of bacterial genera including Alcaligenes, Aspergillus, Escherichia, and Pseudomonas (PMID: 23194589, 2310183, 9680309). Indole plays a role in bacterial biofilm formation, bacterial motility, bacterial virulence, plasmid stability, and antibiotic resistance. It also functions as an intercellular signalling molecule (PMID: 26115989). Recently, it was determined that the bacterial membrane-bound histidine sensor kinase (HK) known as CpxA acts as a bacterial indole sensor to facilitate signalling (PMID: 31164470). It has been found that decreased indole concentrations in the gut promote bacterial pathogenesis, while increased levels of indole in the gut decrease bacterial virulence gene expression (PMID: 31164470). As a result, enteric pathogens sense a gradient of indole concentrations in the gut to migrate to different niches and successfully establish an infection.

Pentane is absorbed following inhalation and ingestion, and to a small extent from dermal exposure.
The chemical properties of the toluidines are quite similar to those of aniline and toluidines have properties in common with other aromatic amines. Due to the amino group bonded to the aromatic ring, the toluidines are weakly basic. None of the toluidines is very soluble in pure water, but will become soluble if the aqueous solution is acidic due to formation of ammonium salts, as usual for organic amines. At room temperature and pressure, ortho- and meta-toluidines are viscous liquids, but para-toluidine is a flaky solid. This can be explained by the fact that the p-toluidine molecules are more symmetrical and fit into a crystalline structure more easily. p-Toluidine can be obtained from reduction of p-nitrotoluene. p-Toluidine reacts with formaldehyde to form Troger's base.

Promazine is only found in individuals that have used or taken this drug. It is a phenothiazine with actions similar to chlorpromazine but with less antipsychotic activity. It is primarily used in short-term treatment of disturbed behavior and as an antiemetic. [PubChem]Promazine is an antagonist at types 1, 2, and 4 dopamine receptors, 5-HT receptor types 2A and 2C, muscarinic receptors 1 through 5, alpha(1)-receptors, and histamine H1-receptors. Promazine's antipsychotic effect is due to antagonism at dopamine and serotonin type 2 receptors, with greater activity at serotonin 5-HT2 receptors than at dopamine type-2 receptors. This may explain the lack of extrapyramidal effects. Promazine does not appear to block dopamine within the tubero-infundibular tract, explaining the lower incidence of hyperprolactinemia than with typical antipsychotic agents or risperidone. Antagonism at muscarinic receptors, H1-receptors, and alpha(1)-receptors also occurs with promazine.
Ethinyl estradiol. A semisynthetic alkylated estradiol with a 17-alpha-ethinyl substitution. It has high estrogenic potency when administered orally, and is often used as the estrogenic component in oral contraceptives. -- Pubchem; estradiol (17-beta estradiol) (also oestradiol) is a sex hormone. Labelled the "female" hormone but also present in males it represents the major estrogen in humans. Critical for sexual functioning, estradiol also supports bone growth. -- Wikipedia; One of the fascinating twists to mammalian sexual differentiation is that estradiol is one of the two active metabolites of testosterone in males (the other being dihydrotestosterone). estradiol cannot be transferred readily from the circulation into the brain. Since fetuses of both sexes are exposed to similarly high levels of maternal estradiol, it can play little role in prenatal sexual differentiation. However, testosterone enters the central nervous system more freely and significant amounts are aromatized to estradiol within the brain of most male mammals, including humans. There is now much evidence that the programming of adult male sexual behavior in "lower mammals," (such as mounting rather than lordosis behavior), is largely dependent on estradiol produced in the central nervous system during prenatal life and early infancy from testosterone. We do not yet know whether this process plays a minimal or significant part in human sexual behaviors. -- Wikipedia; A synthetic form of estradiol, called ethinyl estradiol is a major component of hormonal contraceptive devices. Combined oral contraceptives contain ethinyl estradiol and a progestin, which both contribute to the inhibition of GnRH, LH, and FSH. The inhibition of these hormones accounts for the ability of combined oral contraceptives or birth control pills to prevent ovulation and thus prevent pregnancy. Other types of hormonal birth control contain only progestins and no ethinyl estradiol. -- Wikipedia.

These are 3-hydroxylated C19 steroid hormones. Epitestosterone is an endogenous steroid and a C-17 epimer of the androgen sex hormone testosterone. It is a weak competitive antagonist of the androgen receptor (AR) and a potent 5alpha-reductase inhibitor. Structurally, epitestosterone differs from testosterone only in the configuration at the hydroxy-bearing carbon, C17. Epitestosterone is believed to form in a similar way to testosterone with 50% of epitestosterone production in human males taking place in the testis. Epitestosterone levels are typically highest in young males; however, by adulthood, most healthy males exhibit a testosterone to epitestosterone ratio (T/E ratio) of about 1:1 (PMID: 11901061). A study of Australian athletes found that the mean T/E ratio in the study was 1.15:1. Another study found that the max T/E ratio for the 95th percentile of athletes was 3.71:1, and the max T/E ratio for the 99th percentile was 5.25:1. Epitestosterone has not been shown to enhance athletic performance, although administration of epistestosterone can be used to mask a high level of testosterone if the standard T/E ratio test is used. As such, epitestosterone is banned by many sporting authorities as a masking agent for testosterone. Interestingly, small amounts of ethanol can elevate T/E values, with women being more susceptible (PMID: 28671321).

Diethyl malonate, also known as dicarbethoxymethane or ethyl propanedioate, belongs to the class of organic compounds known as dicarboxylic acids and derivatives. These are organic compounds containing exactly two carboxylic acid groups. Diethyl malonate is a sweet, apple, and fruity tasting compound. Diethyl malonate has been detected, but not quantified, in a few different foods, such as alcoholic beverages, evergreen blackberries, and fruits. Like other esters, this compound can undergo bromination at the alpha position. Fischer esterification gives diethyl malonate: One of the principal uses of this compound is in the malonic ester synthesis. It occurs naturally in grapes and strawberries as a colourless liquid with an apple-like odour, and is used in perfumes. Malonic acid is a rather simple dicarboxylic acid, with the two carboxyl groups close together. The hydrogen atoms on a carbon adjacent to two carbonyl groups are even more acidic because the carbonyl groups help stabilize the carbanion resulting from the removal of that proton. Like many other esters, this compound can undergo the Claisen ester condensation. This alkylated 1,3-dicarbonyl compound (3) readily undergoes decarboxylation with loss of carbon dioxide, to give a substituted acetic acid, using Sodium ethoxide as the preferred base. The use of aqueous sodium hydroxide may give the base hydrolysis products: sodium malonate and ethanol.

This could make 1,3-diaminopropane a potential biomarker for the consumption of these foods.
Ethyl formate, also known as areginal or ethyl methanoate, belongs to the class of organic compounds known as carboxylic acid esters. These are carboxylic acid derivatives in which the carbon atom from the carbonyl group is attached to an alkyl or an aryl moiety through an oxygen atom (forming an ester group). Ethyl formate is an alcohol, bitter, and cognac tasting compound. Ethyl formate has been detected, but not quantified, in several different foods, such as citrus, pineapples, apples, fruits, and pomes. This could make ethyl formate a potential biomarker for the consumption of these foods. It occurs naturally in the body of ants and in the stingers of bees. Ethyl formate has the characteristic smell of rum and is also partially responsible for the flavor of raspberries. The U.S. National Institute for Occupational Safety and Health (NIOSH) also considers a time-weighted average of 100 ppm over an eight-hour period as the recommended exposure limit. Ethyl formate is an ester formed when ethanol (an alcohol) reacts with formic acid (a carboxylic acid). According to the U.S Occupational Safety and Health Administration (OSHA), ethyl formate can irritate eyes, skin, mucous membranes, and the respiratory system of humans and other animals; it is also a central nervous system depressant. Ethyl formate has been identified in dust clouds in an area of the Milky Way galaxy called Sagittarius B2 and it is among 50 molecular species identified using the 30 metre IRAM radiotelescope.

Benzaldehyde is occasionally found as a volatile component of urine. Benzaldehyde is an aromatic aldehyde used in cosmetics as a denaturant, a flavoring agent, and as a fragrance. Currently used in only seven cosmetic products, its highest reported concentration of use was 0.5% in perfumes. Benzaldehyde is a generally regarded as safe (GRAS) food additive in the United States and is accepted as a flavoring substance in the European Union. Because Benzaldehyde rapidly metabolizes to Benzoic Acid in the skin, the available dermal irritation and sensitization data demonstrating no adverse reactions to Benzoic Acid were considered supportive of the safety of Benzaldehyde. Benzaldehyde is absorbed through skin and by the lungs, distributes to all well-perfused organs, but does not accumulate in any specific tissue type. After being metabolized to benzoic acid, conjugates are formed with glycine or glucuronic acid, and excreted in the urine. Several studies have suggested that Benzaldehyde can have carcinostatic or antitumor properties. Overall, at the concentrations used in cosmetics, Benzaldehyde was not considered a carcinogenic risk to humans. Although there are limited irritation and sensitization data available for Benzaldehyde, the available dermal irritation and sensitization data and ultraviolet (UV) absorption and phototoxicity data demonstrating no adverse reactions to Benzoic Acid support the safety of Benzaldehyde as currently used in cosmetic products. (PMID:16835129, Int J Toxicol. 2006;25 Suppl 1:11-27.).

Stigmasterol is a phytosterol, meaning it is steroid derived from plants. As a food additive, phytosterols have cholesterol-lowering properties (reducing cholesterol absorption in intestines), and may act in cancer prevention. Phytosterols naturally occur in small amount in vegetable oils, especially soybean oil. One such phytosterol complex, isolated from vegetable oil, is cholestatin, composed of campesterol, stigmasterol, and brassicasterol, and is marketed as a dietary supplement. Sterols can reduce cholesterol in human subjects by up to 15%. The mechanism behind phytosterols and the lowering of cholesterol occurs as follows : the incorporation of cholesterol into micelles in the gastrointestinal tract is inhibited, decreasing the overall amount of cholesterol absorbed. This may in turn help to control body total cholesterol levels, as well as modify HDL, LDL and TAG levels. Many margarines, butters, breakfast cereals and spreads are now enriched with phytosterols and marketed towards people with high cholesterol and a wish to lower it. Stigmasterol is found to be associated with phytosterolemia, which is an inborn error of metabolism.

Ethopropazine is only found in individuals that have used or taken this drug.Ethopropazine (also known as profenamine hydrochloride) is a medication derived from phenothiazine. It is primarily used as an antidyskinetic to treat parkinsonism. It is sold under the trade names Parsidol in the United States and Parsidan in Canada.Ethopropazine's antiparkinson action can be attributed to its anticholinergic properties. Ethopropazine partially blocks central (striatal) cholinergic receptors, thereby helping to balance cholinergic and dopaminergic activity in the basal ganglia; salivation may be decreased, and smooth muscle may be relaxed. Drug-induced extrapyramidal symptoms and those due to parkinsonism may be relieved, but tardive dyskinesia is not alleviated and may be aggravated by anticholinergic effects. Ethopropazine's local anesthetic effect is due to its antagonism of the NMDA glutamate receptor. Glutamate is recognized as an important transmitter in nociceptive pathways, and the N-methyl-D-aspartate (NMDA) subtype of the glutamate receptor, in particular, has been implicated in the mediation of neuropathic pain. Excessive release of glutamate at NMDA receptors on dorsal horn neurons of the spinal cord results in hyperactivation and hypersensitivity of these receptors (perceived as hyperalgesia), thought to be an integral feature of neuropathic pain.

Butanal is an apple, bready, and chocolate tasting compound. Outside of the human body, Butanal is found, on average, in the highest concentration within cow milk and carrots. Butanal has also been detected, but not quantified in several different foods, such as hard wheats, borages, ostrich ferns, skunk currants, and fennels. This could make butanal a potential biomarker for the consumption of these foods. The dominant technology involves the use of rhodium catalysts derived from the water-soluble ligand Tppts. Butyraldehyde is produced almost exclusively by the hydroformylation of propylene:CH3CHCH2 + H2 + CO → CH3CH2CH2CHO. Traditionally, hydroformylation was catalyzed by cobalt carbonyl and later rhodium complexes of triphenylphosphine. At one time, it was produced industrially by the catalytic hydrogenation of crotonaldehyde, which is derived from acetaldehyde. Butyraldehyde can be produced by the catalytic dehydrogenation of n-butanol. This compound is the aldehyde derivative of butane. An aqueous solution of the rhodium catalyst converts the propylene to the aldehyde, which forms a lighter immiscible phase. About 6 billion kilograms are produced annually by hydroformylation. It is a colourless flammable liquid with an unpleasant smell.
