Common Name(R)-4-(2-(2-(2-Methylpyrrolidin-1-yl)ethyl)benzofuran-5-yl)benzonitrile
Description(R)-4-(2-(2-(2-Methylpyrrolidin-1-yl)ethyl)benzofuran-5-yl)benzonitrile, also known as ABT 239, belongs to the class of organic compounds known as phenylbenzofurans. These are organic aromatic compounds that contain a phenyl group attached to a benzofuran moiety. Benzofuran is a bicyclic compound containing a benzene fused to a furan. Based on a literature review very few articles have been published on (R)-4-(2-(2-(2-Methylpyrrolidin-1-yl)ethyl)benzofuran-5-yl)benzonitrile. This compound has been identified in human blood as reported by (PMID: 31557052 ). (r)-4-(2-(2-(2-methylpyrrolidin-1-yl)ethyl)benzofuran-5-yl)benzonitrile is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (R)-4-(2-(2-(2-Methylpyrrolidin-1-yl)ethyl)benzofuran-5-yl)benzonitrile 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.
