Common NameLefradafibanum
Descriptionmethyl 2-(2-{[(4'-{amino[(methoxycarbonyl)imino]methyl}-[1,1'-biphenyl]-4-yl)oxy]methyl}-5-hydroxy-3,4-dihydro-2H-pyrrol-4-yl)acetate belongs to the class of organic compounds known as biphenyls and derivatives. These are organic compounds containing to benzene rings linked together by a C-C bond. Based on a literature review very few articles have been published on methyl 2-(2-{[(4'-{amino[(methoxycarbonyl)imino]methyl}-[1,1'-biphenyl]-4-yl)oxy]methyl}-5-hydroxy-3,4-dihydro-2H-pyrrol-4-yl)acetate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Lefradafibanum is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Lefradafibanum 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.
