Metabolite Identification
Common NameFuro(3,4-b)pyridine-3-carboxylic acid, 1,4,5,7-tetrahydro-4-(2-(difluoromethoxy)phenyl)-2-methyl-5-oxo-, ethyl ester
Descriptionethyl 4-[2-(difluoromethoxy)phenyl]-2-methyl-5-oxo-1H,4H,5H,7H-furo[3,4-b]pyridine-3-carboxylate, also known as CGP 28 392, belongs to the class of organic compounds known as phenol ethers. These are aromatic compounds containing an ether group substituted with a benzene ring. Based on a literature review very few articles have been published on ethyl 4-[2-(difluoromethoxy)phenyl]-2-methyl-5-oxo-1H,4H,5H,7H-furo[3,4-b]pyridine-3-carboxylate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Furo(3,4-b)pyridine-3-carboxylic acid, 1,4,5,7-tetrahydro-4-(2-(difluoromethoxy)phenyl)-2-methyl-5-oxo-, ethyl ester is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Furo(3,4-b)pyridine-3-carboxylic acid, 1,4,5,7-tetrahydro-4-(2-(difluoromethoxy)phenyl)-2-methyl-5-oxo-, ethyl ester 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.
