Metabolite Identification
Common Name4-hydroxy-3-nitrophenylacetate
Description4-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 ).
