Pyrimidine 2-deoxyribonucleosides are compounds consisting of a pyrimidine linked to a ribose which lacks a hydroxyl group at position 2. Deoxythymidine is soluble (in water) and a very weakly acidic compound (based on its pKa). Deoxythymidine can be synthesized from thymine. Deoxythymidine is also a parent compound for other transformation products, including but not limited to, tritiated thymidine, alpha-tritiated thymidine, and 5,6-dihydrothymidine. Deoxythymidine can be found in a number of food items such as butternut squash, mammee apple, catjang pea, and climbing bean, which makes deoxythymidine a potential biomarker for the consumption of these food products. Deoxythymidine can be found primarily in most biofluids, including blood, amniotic fluid, cerebrospinal fluid (CSF), and urine, as well as throughout most human tissues. Deoxythymidine exists in all living species, ranging from bacteria to humans. In humans, deoxythymidine is involved in the pyrimidine metabolism. Deoxythymidine is also involved in few metabolic disorders, which include beta ureidopropionase deficiency, dihydropyrimidinase deficiency, MNGIE (mitochondrial neurogastrointestinal encephalopathy), and UMP synthase deficiency (orotic aciduria). Moreover, deoxythymidine is found to be associated with canavan disease and degenerative disc disease.

Deoxythymidine (or thymidine) is the DNA nucleoside T, which pairs with deoxyadenosine (A) in double-stranded DNA. Therefore, thymidine is essential to all life. Indeed, thymidine exists in all living species, ranging from bacteria to plants to humans. Within humans, thymidine participates in a number of enzymatic reactions. In particular, thymidine can be biosynthesized from 5-thymidylic acid through its interaction with the enzyme cytosolic purine 5-nucleotidase. In addition, thymidine can be converted into 5-thymidylic acid; which is catalyzed by the enzyme thymidine kinase. Deoxythymidine can be phosphorylated with one, two or three phosphoric acid groups, creating dTMP (deoxythymidine monophosphate), dTDP, or dTTP (for the di- and tri- phosphates, respectively). dTMP can be incorporated into DNA via DNA polymerases. In cell biology, thymidine can be used to synchronize the cells in S phase.

L-Tyrosine
Tyrosine (Tyr) or L-tyrosine is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. L-tyrosine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Tyrosine is found in all organisms ranging from bacteria to plants to animals. It is classified as a non-polar, uncharged (at physiological pH) aromatic amino acid. Tyrosine is a non-essential amino acid, meaning the body can synthesize it – usually from phenylalanine. The conversion of phenylalanine to tyrosine is catalyzed by the enzyme phenylalanine hydroxylase, a monooxygenase. This enzyme catalyzes the reaction causing the addition of a hydroxyl group to the end of the 6-carbon aromatic ring of phenylalanine, such that it becomes tyrosine. Tyrosine is found in many high-protein food products such as chicken, turkey, fish, milk, yogurt, cottage cheese, cheese, peanuts, almonds, pumpkin seeds, sesame seeds, soy products, lima beans, avocados and bananas. Tyrosine is one of the few amino acids that readily passes the blood-brain barrier. Once in the brain, it is a precursor for the neurotransmitters dopamine, norepinephrine and epinephrine, better known as adrenalin. These neurotransmitters are an important part of the bodys sympathetic nervous system, and their concentrations in the body and brain are directly dependent upon dietary tyrosine. Tyrosine is not found in large concentrations throughout the body, probably because it is rapidly metabolized. Folic acid, copper and vitamin C are cofactor nutrients of these reactions. Tyrosine is also the precursor for hormones, including thyroid hormones (diiodotyrosine), catecholestrogens and the major human pigment, melanin. Tyrosine is an important amino acid in many proteins, peptides and even enkephalins, the bodys natural pain reliever. Valine and other branched amino acids, and possibly tryptophan and phenylalanine may reduce tyrosine absorption. A number of genetic errors of tyrosine metabolism have been identified, such as hawkinsinuria and tyrosinemia I. The most common feature of these diseases is the increased amount of tyrosine in the blood, which is marked by decreased motor activity, lethargy and poor feeding. Infection and intellectual deficits may occur. Vitamin C supplements can help reverse these disease symptoms. Some adults also develop elevated tyrosine in their blood. This typically indicates a need for more vitamin C. More tyrosine is needed under stress, and tyrosine supplements prevent the stress-induced depletion of norepinephrine and can help aleviate biochemical depression. However, tyrosine may not be good for treating psychosis. Many antipsychotic medications apparently function by inhibiting tyrosine metabolism. L-Dopa, which is directly used in Parkinsons, is made from tyrosine. Tyrosine, the nutrient, can be used as an adjunct in the treatment of Parkinsons. Peripheral metabolism of tyrosine necessitates large doses of tyrosine, however, compared to L-Dopa (http://www.dcnutrition.com). In addition to its role as a precursor for neurotransmitters, tyrosine plays an important role for the function of many proteins. Within many proteins or enzymes, certain tyrosine residues can be tagged (at the hydroxyl group) with a phosphate group (phosphorylated) by specialized protein kinases. In its phosphorylated form, tyrosine is called phosphotyrosine. Tyrosine phosphorylation is considered to be one of the key steps in signal transduction and regulation of enzymatic activity. Tyrosine (or its precursor phenylalanine) is also needed to synthesize the benzoquinone structure which forms part of coenzyme Q10. L-tyrosine is an optically active form of tyrosine having L-configuration. It has a role as an EC 1.3.1.43 (arogenate dehydrogenase) inhibitor, a nutraceutical, a micronutrient and a fundamental metabolite. It is an erythrose 4-phosphate/phosphoenolpyruvate family amino acid, a proteinogenic amino acid, a tyrosine and a L-alpha-amino acid. It is functionally related to a L-tyrosinal. It is a conjugate base of a L-tyrosinium. It is a conjugate acid of a L-tyrosinate(1-). It is an enantiomer of a D-tyrosine. It is a tautomer of a L-tyrosine zwitterion. Tyrosine is a non-essential amino acid. In animals it is synthesized from [phenylalanine]. It is also the precursor of [epinephrine], thyroid hormones, and melanin. L-Tyrosine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). L-Tyrosine is the levorotatory isomer of the aromatic amino acid tyrosine. L-tyrosine is a naturally occurring tyrosine and is synthesized in vivo from L-phenylalanine. It is considered a non-essential amino acid; however, in patients with phenylketonuria who lack phenylalanine hydroxylase and cannot convert phenylalanine into tyrosine, it is considered an essential nutrient. In vivo, tyrosine plays a role in protein synthesis and serves as a precursor for the synthesis of catecholamines, thyroxine, and melanin. Tyrosine is an essential amino acid that readily passes the blood-brain barrier.

L-Methionine
Methionine (Met), also known as L-methionine, is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. Methionine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Methionine is found in all organisms ranging from bacteria to plants to animals. It is classified as an aliphatic, non-polar amino acid. Methionine is an essential amino acid (there are 9 essential amino acids), meaning the body cannot synthesize it, and it must be obtained from the diet. It is required for normal growth and development of humans, other mammals, and avian species. In addition to being a substrate for protein synthesis, methionine is an intermediate in transmethylation reactions, serving as the major methyl group donor in vivo, including the methyl groups for DNA and RNA intermediates. Methionine is a methyl acceptor for 5-methyltetrahydrofolate-homocysteine methyltransferase (methionine synthase), the only reaction that allows for the recycling of this form of folate, and is also a methyl acceptor for the catabolism of betaine. Methionine is the metabolic precursor for cysteine. Only the sulfur atom from methionine is transferred to cysteine; the carbon skeleton of cysteine is donated by serine (PMID: 16702340 ). There is a general consensus concerning normal sulfur amino acid (SAA) requirements. WHO recommendations amount to 13 mg/kg per 24 h in healthy adults. This amount is roughly doubled in artificial nutrition regimens. In disease or after trauma, requirements may be altered for methionine, cysteine, and taurine. Although in specific cases of congenital enzyme deficiency, prematurity, or diminished liver function, hypermethioninemia or hyperhomocysteinemia may occur, SAA supplementation can be considered safe in amounts exceeding 2-3 times the minimum recommended daily intake. Apart from some very specific indications (e.g. acetaminophen poisoning) the usefulness of SAA supplementation is not yet established (PMID: 16702341 ). Methionine is known to exacerbate psychopathological symptoms in schizophrenic patients, but there is no evidence of similar effects in healthy subjects. The role of methionine as a precursor of homocysteine is the most notable cause for concern. Acute doses of methionine can lead to acute increases in plasma homocysteine, which can be used as an index of the susceptibility to cardiovascular disease. Sufficiently high doses of methionine can actually result in death. Longer-term studies in adults have indicated no adverse consequences of moderate fluctuations in dietary methionine intake, but intakes higher than 5 times the normal amount resulted in elevated homocysteine levels. These effects of methionine on homocysteine and vascular function are moderated by supplements of vitamins B-6, B-12, C, and folic acid (PMID: 16702346 ). When present in sufficiently high levels, methionine can act as an atherogen and a metabotoxin. An atherogen is a compound that when present at chronically high levels causes atherosclerosis and cardiovascular disease. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of methionine are associated with at least ten inborn errors of metabolism, including cystathionine beta-synthase deficiency, glycine N-methyltransferase deficiency, homocystinuria, tyrosinemia, galactosemia, homocystinuria-megaloblastic anemia due to defects in cobalamin metabolism, methionine adenosyltransferase deficiency, methylenetetrahydrofolate reductase deficiency, and S-adenosylhomocysteine (SAH) hydrolase deficiency. Chronically elevated levels of methionine in infants can lead to intellectual disability and othe...

Ephedrine
Ephedrine is only found in individuals who have consumed this drug. Ephedrine is an alpha- and beta-adrenergic agonist that may also enhance release of norepinephrine. It has been used in the treatment of several disorders including asthma, heart failure, rhinitis, and urinary incontinence, and for its central nervous system stimulatory effects in the treatment of narcolepsy and depression. It has become less extensively used with the advent of more selective agonists. [PubChem] Ephedrine is similar in molecular structure to the well-known drugs phenylpropanolamine and methamphetamine, as well as to the important neurotransmitter epinephrine (adrenalin). Chemically, it is an alkaloid with a phenethylamine skeleton found in various plants in the genus Ephedra (family Ephedraceae). It works mainly by increasing the activity of norepinephrine (noradrenalin) on adrenergic receptors. It is most usually marketed as the hydrochloride or sulfate salt.

Angiotensin IV is one of the N-terminal angiotensin degradation products of angiotensin II. Angiotensin IV (AngIV) mediates important physiologic functions in the central nervous system, including blood flow regulation, processes underlying to learning and memory, and presents anticonvulsant activity. The presence of AngIV-specific binding sites has been identified in various mammalian tissues, including blood vessels, heart, kidney, and brain. Besides the presence of AngIV binding sites in the cardiovascular system, the major AngIV synthesizing enzymes aminopeptidase N (APN) and aminopeptidase B (APB) are also expressed in different cell types of this system. AngIV activates several protein kinases, including phosphatidylinositol 3 kinase, PI-dependent kinase-1, extracellular signal-related kinases (ERK), protein kinase B-α/Akt, and p70 ribosomal S6 kinase. AngIV could contribute to vascular damage, increasing the production of monocyte chemoattractant protein-1, the main chemokine involved in monocyte recruitment, and up-regulates the expression of the adhesion molecule intercellular adhesion molecule-1 that is involved in the attachment and transmigration of circulating cells into the damaged tissue.

N-Nitrosodimethylamine
N-Nitrosodimethylamine is found in pepper (Capsicum annuum). N-Nitrosodimethylamine is a food contaminant especially in cured meat products. N-Nitrosodimethylamine (NDMA), also known as dimethylnitrosamine (DMN), is a semi-volatile organic chemical that is highly toxic and is a suspected human carcinogen. The US Environmental Protection Agency has determined that the maximum admissible concentration of NDMA in drinking water is 7 ng L 1. The EPA has not yet set a regulatory maximum contaminant level (MCL) for drinking water. At high doses, it is a "potent hepatotoxin that can cause fibrosis of the liver" in rats. The induction of liver tumors in rats after chronic exposure to low doses is well-documented. Its toxic effects on humans are inferred from animal experiments but not well-established experimentally. NDMA is an industrial by-product or waste product of several industrial processes. It first came to attention as a groundwater contaminant in California in 1998 and 1999 at several sites that produced rocket fuel. Manufacturing of unsymmetrical dimethylhydrazine (UDMH), which is a component of rocket fuel that requires NDMA for its synthesis, proved to be the culprit in these cases. Of more general concern, water treatment via chlorination or chloramination of organic nitrogen-containing wastewater can lead to the production of NDMA at potentially harmful levels. Further, NDMA can form or be leached during treatment of water by anion exchange resins. Finally, NDMA is found at low levels in numerous items of human consumption including cured meat, fish, beer, and tobacco smoke, it is, however, unlikely to bioaccumulate CONFIDENCE standard compound; EAWAG_UCHEM_ID 3447 Food contaminant especies in cured meat products

Morpholine
Morpholine is a permitted (FDA) in edible coatings for fruit and vegetables. Morpholine is a food contaminant arising from its use as a boiler water additive Morpholine is a common additive, in ppm concentrations, for pH adjustment in both fossil fuel and nuclear power plant steam systems. Morpholine is used because its volatility is about the same as water, so once it is added to the water, its concentration becomes distributed rather evenly in both the water and steam phases. Its pH adjusting qualities then become distributed throughout the steam plant to provide corrosion protection. Morpholine is often used in conjunction with low concentrations of hydrazine or ammonia to provide a comprehensive all-volatile treatment chemistry for corrosion protection for the steam systems of such plants. Morpholine decomposes reasonably slowly in the absence of oxygen even at the high temperatures and pressures in these steam systems. Morpholine is an organic chemical compound having the chemical formula O(CH2CH2)2NH. This heterocycle, pictured at right, features both amine and ether functional groups. Because of the amine, morpholine is a base; its conjugate acid is called morpholinium. For example, when morpholine is neutralized by hydrochloric acid, one obtains the salt morpholinium chloride. Morpholine is widely used in organic synthesis. For example, it is a building block in the preparation of the antibiotic linezolid and the anticancer agent gefitinib (Iressa) Permitted (FDA) in edible coatings for fruit and vegetables.

Isosorbide Dinitrate is only found in individuals that have used or taken this drug. It is a vasodilator used in the treatment of angina pectoris. Its actions are similar to nitroglycerin but with a slower onset of action. [PubChem]Similar to other nitrites and organic nitrates, isosorbide dinitrate is converted to nitric oxide (NO), an active intermediate compound which activates the enzyme guanylate cyclase (atrial natriuretic peptide receptor A). This stimulates the synthesis of cyclic guanosine 3,5-monophosphate (cGMP) which then activates a series of protein kinase-dependent phosphorylations in the smooth muscle cells, eventually resulting in the dephosphorylation of the myosin light chain of the smooth muscle fiber. The subsequent release of calcium ions results in the relaxation of the smooth muscle cells and vasodilation.

[PubChem]Methacycline, a tetracycline antibiotic, is a protein synthesis inhibitors, inhibiting the binding of aminoacyl-tRNA to the mRNA-ribosome complex. Methacycline inhibits cell growth by inhibiting translation. It binds to the 16S part of the 30S ribosomal subunit and prevents the amino-acyl tRNA from binding to the A site of the ribosome. The binding is reversible in nature. Tetracyclines also have been found to inhibit matrix metalloproteinases. This mechanism does not add to their antibiotic effects, but has led to extensive research on chemically modified tetracyclines or CMTs (like incyclinide) for the treatmet of rosacea, acne, and various types of neoplasms.

Metyrosine
Metyrosine is only found in individuals that have used or taken this drug. It is an inhibitor of the enzyme tyrosine 3-monooxygenase, and consequently of the synthesis of catecholamines. It is used to control the symptoms of excessive sympathetic stimulation in patients with pheochromocytoma. (Martindale, The Extra Pharmacopoeia, 30th ed)Metyrosine inhibits tyrosine hydroxylase, which catalyzes the first transformation in catecholamine biosynthesis, i.e., the conversion of tyrosine to dihydroxyphenylalanine (DOPA). Because the first step is also the rate-limiting step, blockade of tyrosine hydroxylase activity results in decreased endogenous levels of catecholamines and their synthesis. This consequently, depletes the levels of the catecholamines dopamine, adrenaline and noradrenaline in the body,usually measured as decreased urinary excretion of catecholamines and their metabolites. One main end result of the catecholamine depletion is a decrease in blood presure.

Furan
Furan is a member of the class of compounds known as furans. These are molecules containing a heterocyclic organic group consisting of a five-membered aromatic ring with four carbon atoms and one oxygen. Furan is aromatic because one of the lone pairs of electrons on the oxygen atom is delocalized into the ring, creating a 4n+2 aromatic system similar to benzene. Because of the aromaticity, furan is flat and lacks discrete double bonds. Furan is a colourless, flammable, highly volatile liquid with a boiling point close to room temperature (31 °C). It is soluble in common organic solvents, including alcohol, ether, and acetone, but is insoluble in water. It has a strong ethereal odour. Furan is found in heat-treated (e.g. cooked, roasted, baked, pasteurized, and sterilized) commercial foods and is produced through thermal degradation of natural food constituents (PMID:22641279). It can be found in roasted coffee, instant coffee, and processed baby foods (PMID:22641279). In particular, the highest furan levels can be detected in coffee, with mean values between 42 and 3 660 ng/g for brewed coffee and roasted coffee beans. Furan can also be detected at levels between 0.2 and 3.2 ng/g in infant formula, from 22 to 24 ng/g in baked beans, from 13 to 17 ng/g in meat products, and from 23 to 24 ng/g in soups. In soy sauce, furan is detectable at 27 ng/g (PMID:26483883). Research has indicated that coffee made in espresso makers and, above all, coffee made from capsules, contains more furan than that made in traditional drip coffee makers, although the levels are still within safe health limits. Various pathways have been reported for the formation of furan: (1) thermal degradation and/or thermal rearrangement of carbohydrates in the presence of amino acids, (2) thermal degradation of certain amino acids (aspartic acid, threonine, alpha-alanine, serine, and cysteine), (3) oxidation of ascorbic acid at higher temperatures, and (4) oxidation of polyunsaturated fatty acids and carotenoids (PMID:26483883). Several studies have reported that furan formation occurs to a large extent during the Maillard reaction. The Maillard reaction involves the thermal degradation and rearrangement of carbohydrates (i.e. non-enzymatic browning reactions during food processing and cooking). Reducing hexoses often go through the Maillard reaction in the presence of amino acids and produce reactive intermediates such as 1-deoxy- and 3-deoxyosones, aldotetrose, and 2-deoxy-3-keto-aldotetrose. 2-Deoxy-3-keto-aldotetrose typically goes through retro-aldol cleavage leading to 3-deoxyosone which undergoes alpha-dicarbonyl cleavage, followed by oxidation and decarboxylation to form 2-deoxyaldotetrose, which is a direct precursor of furan. In addition to the formation of furan via carbohydrate degradation, furan can also be formed through thermal degradation of certain amino acids. Specifically, the amino acids that can form acetaldehyde and glycolaldehyde can produce furan by aldol condensation and cyclization (PMID:26483883). Furan is toxic and may be carcinogenic. In particular, furan is a potent hepatotoxin and hepatocarcinogen in rodents, causing hepatocellular adenomas and carcinomas in rats and mice, and high incidences of cholangiocarcinomas in rats at doses ≥ 2 mg/kg (PMID:22641279).

Cinobufotalin is a natural product found in Bufo and Bufo bufo with data available. Cinobufotalin is a bufadienolide isolated from toad venom and utilized in traditional Chinese medicine (TCM) for its cardiotonic, diuretic and hemostatic effects, with potential cytotoxic and antineoplastic activities. Upon administration and although the exact mechanism of action(s) (MoAs) through which this agent exerts its effects have yet to be fully discovered, cinobufotalin causes DNA fragmentation, decreases mitochondrial membrane potential (MMP), increases intracellular calcium (Ca2+) ion concentrations and reactive oxygen species (ROS) production, upregulates Fas protein and activates cytochrome C, various caspases, Bid and Bax. This causes cell cycle arrest, induces apoptosis and inhibits tumor cell growth and survival. In addition, cinobufotalin inhibits the activity of sphingosine kinase 1 (SphK1) and induces pro-apoptotic ceramide production, which further promotes tumor cell apoptosis. Cinobufotalin also induces mitochondrial protein cyclophilin D (Cyp-D)-dependent opening of the mitochondrial permeability transition pore (mPTP), which may contribute to cinobufotalin-induced non-apoptotic death of certain tumor cells.

Ketones that have one or more alpha-hydrogen atoms undergo keto-enol tautomerization, the tautomer being an enol. Thus, butanone is considered to be an oxygenated hydrocarbon lipid molecule. Butanone is soluble (in water) and an extremely weak acidic compound (based on its pKa). Butanone is an acetone, camphor, and ethereal tasting compound and can be found in a number of food items such as arctic blackberry, onion-family vegetables, sweet orange, and devilfish, which makes butanone a potential biomarker for the consumption of these food products. Butanone can be found primarily in blood, feces, saliva, and urine, as well as in human pancreas and stratum corneum tissues. Moreover, butanone is found to be associated with alcoholism. Butanone is a non-carcinogenic (not listed by IARC) potentially toxic compound.
