3-Hydroxy-2-methylpyridine-4,5-dicarboxylate
3-Hydroxy-2-methylpyridine-4,5-dicarboxylate is an intermediate in vitamin B6 metabolism(KEGG ID C04604). It is the third to last step in the synthesis of succinate semialdehyde, which is an intermediate in butanoate metabolism. 3-Hydroxy-2-methylpyridine-4,5-dicarboxylate is generated from 2-Methyl-3-hydroxy-5-formylpyridine-4-carboxylate and is then converted to 3-hydroxy-2-methylpyridine-5-carboxylate.

2-Amino-5-phosphonopentanoic acid
DL-AP5 (2-APV) is a competitive NMDA (N-methyl-D-aspartate) receptor antagonist. DL-AP5 shows significantly antinociceptive activity. DL-AP5 specifically blocks on channels in the rabbit retina[1][2][3].
4-hydroxy-3-nitrophenylacetate
4-hydroxy-3-nitrophenylacetate, also known as 3-nitro-4-hydroxyphenylacetic acid, is slightly soluble (in water). It is a mildly acidic compound. This metabolite is a member of the class of compounds known as nitrophenols. Nitrophenols are compounds containing a nitrophenol moiety, which consists of a benzene ring bearing both a hydroxyl group and a nitro group on two different ring carbon atoms. Free nitrotyrosine undergoes metabolism to form 3-nitro-4-hydroxyphenylacetic acid (NHPA) which is excreted in the urine (Wikipedia). However, it is not known whether NHPA is derived exclusively from metabolism of nitrotyrosine, or whether it can be formed by nitration of circulating para -hydroxyphenylacetic acid (PHPA), a metabolite of tyrosine (PMID: 12797864). Since the plasma concentration of PHPA is markedly higher than free nitrotyrosine (approx. 400-fold), the nitration of high-circulating endogenous PHPA to form NHPA becomes very significant and accounts for the majority of NHPA excreted in urine (PMID: 12797864).
vanillyl mandelate
Vanillyl mandelate, also known as 3-methoxy-4-hydroxymandelate or vanilmandelic acid, is a member of the class of compounds known as methoxyphenols. Methoxyphenols are compounds containing a methoxy group attached to the benzene ring of a phenol moiety. Vanillyl mandelate is soluble (in water) and a weakly acidic compound (based on its pKa). Vanillyl mandelate can be found in a number of food items such as brazil nut, feijoa, kiwi, and redcurrant, which makes vanillyl mandelate a potential biomarker for the consumption of these food products. Vanillylmandelic acid (VMA) is a chemical intermediate in the synthesis of artificial vanilla flavorings and is an end-stage metabolite of the catecholamines, epinephrine, and norepinephrine. It is produced via intermediary metabolites .
