Metabolite Identification
Common Name4-Nitrophenyl acetate
Description4-Nitrophenyl acetate, also known as p-nitrophenol acetic acid or 4-O2nc6H4oac, belongs to the class of organic compounds known as phenol esters. These are aromatic compounds containing a benzene ring substituted by a hydroxyl group and an ester group. Based on a literature review a significant number of articles have been published on 4-Nitrophenyl acetate. This compound has been identified in human blood as reported by (PMID: 31557052 ). 4-nitrophenyl acetate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4-Nitrophenyl acetate is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.

Enzymes

General function:
Not Available
Specific function:
Storage protein of tuber. Involved in protection against oxidative stress (Probable). Has carbonate dehydratase and weak trypsin inhibitor activity detected by measuring the dehydration of sodium bicarbonate and the inhibition of trypsin-catalyzed hydrolysis of N-benzoyl-L-arginine-4-nitro anilide, respectively (PubMed:10552514). Contrarily, no carbonate dehydratase or trypsin inhibitor activity detected by measuring the hydrolysis of 4-nitrophenyl acetate or the inhibition of bovine trypsin-catalyzed hydrolysis of N-benzoyl-L-arginine ethyl ester, respectively (PubMed:15047697). Has dehydroascorbate (DHA) reductase and monodehydroascorbate (MDA) reductase activities (Ref.5). Catalyzes the reactions of carbonate dehydratase and DHA reductase independently of zinc and glutathione (GSH). The coupled reaction is capable of recycling a plant antioxidant ascorbate using ubiquitous compounds H(2)O and CO(2) (By similarity). Exhibits antioxidant activity. Able to scavenge 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and hydroxyl radicals (PubMed:11600050). Exhibits immunomodulatory activity. Activates Toll-like receptor 4 signaling pathways by up-regulating the gene expression of proinflammatory cytokines, such as tumor necrosis factor alpha, interleukin-1 beta and interleukin-6, and chemokines RANTES and MCP-1, in mouse RAW 264.7 macrophages. Stimulates the phagocytosis of E.coli by the LPS-treated mouse macrophages (By similarity).
