Common Name5-O-Ethyl 3-O-methyl (4S)-2,6-dimethyl-4-(3-nitrophenyl)-3,4-dihydropyridine-3,5-dicarboxylate
Description5-ethyl 3-methyl 2,6-dimethyl-4-(3-nitrophenyl)-3,4-dihydropyridine-3,5-dicarboxylate belongs to the class of organic compounds known as dihydropyridinecarboxylic acids and derivatives. Dihydropyridinecarboxylic acids and derivatives are compounds containing a dihydropyridine moiety bearing a carboxylic acid group. Based on a literature review very few articles have been published on 5-ethyl 3-methyl 2,6-dimethyl-4-(3-nitrophenyl)-3,4-dihydropyridine-3,5-dicarboxylate. This compound has been identified in human blood as reported by (PMID: 31557052 ). 5-o-ethyl 3-o-methyl (4s)-2,6-dimethyl-4-(3-nitrophenyl)-3,4-dihydropyridine-3,5-dicarboxylate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 5-O-Ethyl 3-O-methyl (4S)-2,6-dimethyl-4-(3-nitrophenyl)-3,4-dihydropyridine-3,5-dicarboxylate 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.
