Salicyluric acid
Salicyluric acid is an aryl glycine conjugate formed by the body to eliminate excess salicylates, including aspirin. Aspirin is rapidly hydrolysed to salicylic acid which is further metabolized to various compounds, including salicyluric acid (SU) as well as various acyl and phenolic glucuronides, and hydroxylated metabolites. SU is the major metabolite of SA excreted in urine and it is present in the urine of people who have not taken salicylate drugs, although it has no anti-inflammatory effects in humans or in animals. More salicyluric acid (SU) is excreted in the urine of vegetarians than in non-vegetarians, primarily because fruits and vegetables are important sources of dietary salicylates. However, significantly less (10-15X) SU is excreted by vegetarians than individuals taking low-dose aspirin (PMID: 12944546). The induction of the salicyluric acid formation is one of the saturable pathways of salicylate elimination. The formation of the methyl ester of salicyluric acid is observed during the quantitation of salicyluric acid and other salicylate metabolites in urine by high-pressure liquid chromatography. This methyl ester formation causes artificially low values for salicyluric acid and high values for salicylic acid. (PMID: 6101164, 6857178). Salicyluric acid has been found to be a microbial metabolite. Constituent of milk KEIO_ID H028 Salicyluric acid is an endogenous metabolite.
Dopaquinone
Dopaquinone, also known as o-dopaquinone or L-dopaquinone, 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. Dopaquinone is slightly soluble (in water) and a moderately acidic compound (based on its pKa). L-Dopaquinone is a metabolite of L-DOPA and a precursor of melanin. Melanin is synthesized from tyrosine by hydroxylation to dihydroxyphenylalanine (DOPA) and subsequent oxidation to dopaquinone. Both reactions are catalyzed by the enzyme tyrosinase, which is the rate-limiting step. Dopaquinone has an ortho-quinone ring, which is known to be neurotoxic and highly reactive with many other compounds (PMID: 413870). Dopaquinone typically combines with cysteine to form pheomelanin (a pigment-polymer). Alternatively, dopaquinone can be converted to leucodopachrome and eventually to eumelanin (also a pigment-polymer). Dopaquinone can be found in skin and feces. Within the cell, dopaquinone is primarily located in the cytoplasm. Dopaquinone is involved in several metabolic disorders, some of which include transient tyrosinemia, hawkinsinuria, tyrosinemia type I, and alkaptonuria. Chronically high levels of dopaquinone are associated with Parkinsons disease (PD). Many Parkinsons patients are treated with L-DOPA. However, long-term treatment with L-DOPA may actually worsen symptoms or result in neurotic and psychotic symptoms. These may be due to dopachrome and dopaquinone accumulating in the brain of L-DOPA treated patients (PMID: 19131041, PMID: 12373519). Dopaquinone is a substrate of enzyme monophenol monooxygenase [EC 1.14.18.1] in tyrosine metabolism pathway (KEGG). [HMDB]

Leucodopachrome
Leucodopachrome is an indolic intermediate in the melanogenesis pathway, the non-enzymatically product of dopaquinone through cyclization in a reaction whose operation is determined by a pH greater than 4 (melanin synthesis in human pigment cell lysates is maximal at pH 6.8). Leucodopachrome participates in redox exchange with dopaquinone to give the eumelanin precursor dopachrome plus dopa. Dopaquinone (the quinone intermediate resulting from tyrosinase-mediated oxidation of tyrosine, monophenol dihydroxyphenylalanine:oxygen oxidoreductase, EC 1.14.18.1) could be a toxic metabolite in melanin biosynthesis. (PMID: 6807981, 1445949, 413870, 11461115, 11171088, 12755639) [HMDB]. Leucodopachrome is found in many foods, some of which are chives, saffron, leek, and red beetroot. Leucodopachrome is an indolic intermediate in the melanogenesis pathway, the non-enzymatic product of dopaquinone through cyclization in a reaction whose operation is determined by a pH greater than 4 (melanin synthesis in human pigment cell lysates is maximal at pH 6.8).

Leucodopachrome
Indoline substituted with hydroxy groups at C-5 and -6 and a carboxy group at C-2, and with S stereochemistry at C-2.
Dopaquinone
An L-phenylalanine derivative in which the phenyl group of L-phenylalanine is replaced by a 3,4-dioxocyclohexa-1,5-dien-1-yl group.
3-hydroxyhippuric acid
COVID info from PDB, Protein Data Bank Corona-virus Coronavirus SARS-CoV-2 COVID-19 SARS-CoV COVID19 SARS2 SARS 3-Hydroxyhippuric acid is an acyl glycine. Acyl glycines are normally minor metabolites of fatty acids.
L-dopaquinone zwitterion
