5-Aminopentanoic acid
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). 5-aminopentanoic acid is a normal metabolite present in human saliva, with a tendency to elevated concentration in patients with chronic periodontitis.

5-Hydroxylysine
5-Hydroxylysine (Hyl), also known as hydroxylysine or 5-Hydroxy-L-lysine, belongs to the class of organic compounds known as L-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. 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. 5-Hydroxylysine is a hydroxylated derivative of the amino acid lysine that is present in certain collagens, the chief structural protein of mammalian skin and connective tissue. 5-Hydroxylysine arises from a post-translational hydroxy modification of lysine and is biosynthesized from lysine via oxidation by lysyl hydroxylase enzymes. 5-Hydroxylysine can then undergo further modification by glycosylation, giving rise to galactosyl hydroxylysine (GH) and glucosylgalactosyl hydroxylysine (GGH). These glycosylated forms of hydroxylysine contribute to collagen’s unusual toughness and resiliency. The monoglycosylated, galactosyl-hydroxylysine is enriched in bone compared with the disaccharide form, glucosyl-galactosyl-hydroxylysine, which is the major form in skin. 5-Hydroxylysine exists in all eukaryotes, ranging from yeast to humans. It was first discovered in 1921 by Donald Van Slyke. Free forms of hydroxylysine arise through proteolytic degradation of collagen. Urinary excretion of 5-Hydroxylysine and its glycosides can be used as an index of collagen degradation, with high levels being indicative of more rapid or extensive collagen degradation (often seen in patients with thermal burns, Pagets disease of bone or hyperphosphatasia) (PMID: 404321). One of the natural protein-bound amino acids. Occurs free in plant tissues, e.g. Medicago sativa (alfalfa)
Carnosine
Carnosine, which is also known as beta-alanyl-L-histidine) is a dipeptide consisting of the amino acids beta-alanine and histidine. It is found exclusively in animal tissues and is naturally produced in the body by the liver. Carnosine has a pKa value of 6.83, making it a good buffer for the pH range of animal muscles. Since beta-alanine is a non-proteogenic amino acid and is not incorporated into proteins, carnosine can be stored at relatively high concentrations (millimolar) in muscles, with concentrations as high as 17–25 mmol/kg (dry muscle). Carnosine is also highly concentrated in brain tissues. Carnosine has been shown to scavenge reactive oxygen species (ROS) as well as alpha-beta unsaturated aldehydes formed from peroxidation of fatty acids during oxidative stress. The antioxidant mechanism of carnosine is attributed to its chelating effect against divalent metal ions, superoxide dismutase (SOD)-like activity, as well as its ROS and free radicals scavenging ability (PMID: 16406688). Carnosine also buffers muscle cells, and acts as a neurotransmitter in the brain. Carnosine has the potential to suppress many of the biochemical changes that accompany ageing (e.g. protein oxidation, glycation, AGE formation, and cross-linking) and associated pathologies (PMID: 16804013). Some autistic patients take carnosine as a dietary supplement and attribute an improvement in their condition to it. Supplemental carnosine may increase corticosterone levels. This may explain the "hyperactivity" seen in autistic subjects at higher doses. A positive association between muscle tissue carnosine concentration and exercise performance has been found. β-Alanine supplementation is thought increase exercise performance by promoting carnosine production in muscle. Exercise has conversely been found to increase muscle carnosine concentrations, and muscle carnosine content is higher in athletes engaging in anaerobic exercise. Carnosine is also a biomarker for the consumption of meat. Elevated levels of urinary and plasma carnosine are associated with carnosinuria (also known as carnosinemia), which is an inborn error of metabolism. caused by a deficiency of the enzyme carnosinase. Carnosinas cleaves carnosine into its constituent amino acids: β-Alanine and histidine. Carnonsinemia results in an excess of carnosine in the urine, cerebrospinal fluid, blood, and nervous tissue. A variety of neurological symptoms have been associated with carnosinemia. They include: hypotonia, developmental delay, mental retardation, degeneration of axons, sensory neuropathy, tremors, demyelinization, gray matter anomalies, myoclonic seizures, and loss of purkinje fibers. [Spectral] Carnosine (exact mass = 226.10659) and L-Lysine (exact mass = 146.10553) were not completely separated on HPLC under the present analytical conditions as described in AC$XXX.

L-Homoserine
L-homoserine, also known as 2-amino-4-hydroxybutanoic acid or isothreonine, is a member of the class of compounds known as L-alpha-amino acids. L-alpha-amino acids are alpha amino acids which have the L-configuration of the alpha-carbon atom. L-homoserine is soluble (in water) and a moderately acidic compound (based on its pKa). L-homoserine can be found in common pea, which makes L-homoserine a potential biomarker for the consumption of this food product. L-homoserine can be found primarily in blood, feces, and urine, as well as in human prostate tissue. L-homoserine exists in all living species, ranging from bacteria to humans. In humans, L-homoserine is involved in the methionine metabolism. L-homoserine is also involved in several metabolic disorders, some of which include glycine n-methyltransferase deficiency, hypermethioninemia, cystathionine beta-synthase deficiency, and methylenetetrahydrofolate reductase deficiency (MTHFRD). Homoserine (also called isothreonine) is an α-amino acid with the chemical formula HO2CCH(NH2)CH2CH2OH. L-Homoserine is not one of the common amino acids encoded by DNA. It differs from the proteinogenic amino acid serine by insertion of an additional -CH2- unit into the backbone. Homoserine, or its lactone form, is the product of a cyanogen bromide cleavage of a peptide by degradation of methionine . Homoserine is a more reactive variant of the amino acid serine. In this variant, the hydroxyl side chain contains an additional CH2 group which brings the hydroxyl group closer to its own carboxyl group, allowing it to chemically react to form a five-membered ring. This occurs at the point that amino acids normally join to their neighbours in a peptide bond. Homoserine is therefore unsuitable for forming proteins and has been eliminated from the repertoire of amino acids used by living things. Homoserine is the final product on the C-terminal end of the N-terminal fragment following a cyanogen bromide cleavage. (wikipedia). Homoserine is also a microbial metabolite. L-Homoserine.

Pyrrole-2-carboxylic acid
Pyrrole-2-carboxylic acid was synthesized over a century ago, but its history as a compound of biological origin is rather recent. It was first identified as a degradation product of sialic acids, then as a derivative of the oxidation of the D-hydroxyproline isomers by mammalian D-amino acid oxidase. The latter relationship results from the lability of the direct oxidation product, A-pyrroline-4-hydroxy-2-carboxylic acid, which loses water spontaneously to form the pyrrole. A similar reaction is catalyzed by the more specific allohydroxy-D-proline oxidase of Pseudomonas. In whole animal observations, pyrrole-2-carboxylate (PCA) was identified in rat or human urine after administration of the D-isomers of hydroxyproline, a finding ascribable to the action of D-amino acid oxidase. (PMID:4430715). Urinary excretion of N-(pyrrole-2-carboxyl) glycine has been reported in a 5-year-old affected with type II hyperprolinemia; The child has mild developmental delay, recurrent seizures of the grand mal type and EEG alterations. The urinary excretion of the conjugate is stressed, since it appears that only one previous report in the literature described this compound in the urine of two patients affected by this disturbance (PMID 2383933).

Floxuridine is a extreamly potent inhibitor for S. aureus infection and induces cell apoptosis[1][2]. Floxuridine has antiviral effects against HSV and CMV[3].
Anserine
Anserine (beta-alanyl-N-3-methylhistidine) is a dipeptide containing beta-alanine and 3-methylhistidine. It is a derivative of carnosine, which had been methylated. The methyl group of anserine is added to carnosine by the enzyme S-adenosylmethionine: carnosine N-methyltransferase (PMID: 29484990). The enzyme is closely related to histamine N-methyltransferase and appears to be present in a majority of anserine-producing species (PMID: 23705015). Anserine is a generally a more metabolically stable derivative of carnosine. Anserine can be found in the skeletal muscle and brain of certain mammals (rabbits, cattle), migratory fish and birds. This dipeptide is normally absent from human tissues and body fluids, and its appearance there is usually an artifact of diet. Anserine can also arise from serum carnosinase deficiency. (OMIM 212200). Anserine was first discovered in goose muscle in 1929, and was named after this extraction (anser is Latin for goose). Anserine, which is water-soluble, is found at high levels in the muscles of different non-human vertebrates, with poultry, rabbit, tuna, plaice, and salmon having generally higher contents than other marine foods, beef, or pork (PMID: 31908682). An increase of urinary anserine excretion has been found in humans after the consumption of chicken, rabbit, and tuna and has been associated with intake of chicken, salmon, and, to a lesser extent, beef (PMID: 31908682). Anserine can undergo cleavage to give rise to 3-methylhistidine.(3-MH). The dipeptide balenine, common in some whales, cleaves to form 1-methylhistidine (1-MH) (PMID: 31908682). There is considerable confusion with regard to the nomenclature of the methylated nitrogen atoms on the imidazole ring of histidine and other histidine-containing peptides such as anserine. In particular, older literature (mostly prior to the year 2000) designated anserine (N-pi methylated) as beta-alanyl-N1-methyl-histidine, whereas according to standard IUPAC nomenclature, anserine is correctly named as beta-alanyl-N3-methyl-histidine. As a result, many papers published prior to the year 2000 incorrectly identified 1MH as a specific marker for dietary consumption of certain foods or various pathophysiological effects when they really were referring to 3MH or vice versa (PMID: 24137022). In particular balenine (a whale or snake-specific dipeptide with 1MH) was often confused with anserine (the poultry dipeptide with 3MH). An animal model study of Alzheimers disease using mice found that treatment with anserine reduced memory loss (PMID: 28974740). Anserine reduced glial inflammatory activity (particularly of astrocyte). The study also found that anserine-treated mice had greater pericyte surface area. The greater area of pericytes was commensurate with improved memory. The anserine-treated mice overall performed better on a spatial memory test (Morris Water Maze) (PMID: 28974740). A human study on 84 elderly subjects showed that subjects who took anserine and carnosine supplements for one year showed increased blood flow in the prefrontal cortex on MRI (PMID: 29896423).

Xanthosine
Xanthosine, also known as xanthine riboside, belongs to the class of organic compounds known as purine nucleosides. Purine nucleosides are compounds comprising a purine base attached to a ribosyl or deoxyribosyl moiety. Xanthosine is a nucleoside derived from xanthine and ribose. Xanthosine exists in all living species, ranging from bacteria to plants to humans. In plants xanthosine is the biosynthetic precursor to 7-methylxanthosine which is produced by the action of the enzyme known as 7-methylxanthosine synthase. 7-Methylxanthosine in turn is the precursor to theobromine (the active alkaloid in chocolate), which in turn is the precursor to caffeine, the active alkaloid in coffee and tea. Within humans, xanthosine participates in a number of enzymatic reactions. In particular, xanthosine can be biosynthesized from xanthylic acid; which is catalyzed by the enzyme cytosolic purine 5-nucleotidase. In addition, xanthosine can be converted into xanthine and ribose 1-phosphate; which is mediated by the enzyme purine nucleoside phosphorylase. Xanthosine monophosphate (XMP) is an intermediate in purine metabolism, formed from IMP (inosine monophosphate).

Beta-Alanine
beta-Alanine is the only naturally occurring beta-amino acid - an amino acid in which the amino group is at the beta-position from the carboxylate group. It is formed in vivo by the degradation of dihydrouracil and carnosine. It is a component of the naturally occurring peptides carnosine and anserine and also of pantothenic acid (vitamin B-5), which itself is a component of coenzyme A. Under normal conditions, beta-alanine is metabolized into acetic acid. beta-Alanine can undergo a transanimation reaction with pyruvate to form malonate-semialdehyde and L-alanine. The malonate semialdehyde can then be converted into malonate via malonate-semialdehyde dehydrogenase. Malonate is then converted into malonyl-CoA and enter fatty acid biosynthesis. Since neuronal uptake and neuronal receptor sensitivity to beta-alanine have been demonstrated, beta-alanine may act as a false transmitter replacing gamma-aminobutyric acid. When present in sufficiently high levels, beta-alanine can act as a neurotoxin, a mitochondrial toxin, and a metabotoxin. A neurotoxin is a compound that damages the brain or nerve tissue. A mitochondrial toxin is a compound that damages mitochondria and reduces cellular respiration as well as oxidative phosphorylation. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of beta-alanine are associated with at least three inborn errors of metabolism, including GABA-transaminase deficiency, hyper-beta-alaninemia, and methylmalonate semialdehyde dehydrogenase deficiency. beta-Alanine is a central nervous system (CNS) depressant and is an inhibitor of GABA transaminase. The associated inhibition of GABA transaminase and displacement of GABA from CNS binding sites can also lead to GABAuria (high levels of GABA in the urine) and convulsions. In addition to its neurotoxicity, beta-alanine reduces cellular levels of taurine, which are required for normal respiratory chain function. Cellular taurine depletion is known to reduce respiratory function and elevate mitochondrial superoxide generation, which damages mitochondria and increases oxidative stress (PMID: 27023909). Individuals suffering from mitochondrial defects or mitochondrial toxicity typically develop neurotoxicity, hypotonia, respiratory distress, and cardiac failure. beta-Alanine is a biomarker for the consumption of meat, especially red meat. Widely distributed in plants including algae, fungi and many higher plants. Flavouring ingredient β-Alanine. CAS Common Chemistry.

Homocarnosine
Homocarnosine is a normal human metabolite, the brain-specific dipeptide of gamma-aminobutyric acid (GABA) and histidine. (PMID 1266573). Increased concentration of CSF homocarnosine has been found in familial spastic paraplegia. (PMID 842287). Homocarnosinosis (an inherited disorder, OMIM 236130) is characterized by an elevated level of the dipeptide homocarnosine (Hca) in the Cerebrospinal fluid (CSF) and the brain and by carnosinuria and serum carnosinase deficiency, and can co-exist with paraplegia, retinitis pigmentosa, and a progressive mental deficiency. (PMID 3736769). In glial tumors of human brain the content of homocarnosine has been found to be lower than in brain tissue (PMID 1032224), while an increase in content of homocarnosine was observed in brain tissue of animals under experimental trauma of cranium.

Cyclopentanone
Cyclopentanone belongs to the class of organic compounds known as ketones. These are organic compounds in which a carbonyl group is bonded to two carbon atoms R2C=O (neither R may be a hydrogen atom). Ketones that have one or more alpha-hydrogen atoms undergo keto-enol tautomerization, the tautomer being an enol. Cyclopentanone is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Thus, cyclopentanone is considered to be an oxygenated hydrocarbon lipid molecule. Cyclopentanone is a cyclic ketone, structurally similar to cyclopentane, consisting of a five-membered ring containing a ketone functional group. Cyclopentanone is a colorless liquid organic compound with a peppermint-like odor. Cyclopentanone is found in various foods, including potato and tomato, and cooked foods, e.g. butter, meats, coffee, roasted peanut. Cyclopentanone is also used as a flavouring ingredient.

Dimercaprol
Dimercaprol is a traditional chelating agent developed by British biochemists at Oxford University during World War II. It was developed as an experimental antidote against the arsenic-based poison gas Lewisite. It has been used clinically since 1949 in arsenic, cadmium and mercury poisoning. In addition, it has in the past been used for the treatment of Wilsons disease, a genetic disorder in which the body tends to retain copper. Dimercaprol is a potentially toxic drug, and its use may be accompanied by multiple side effects.
