Metabolite Identification
Common NameAbexinostat
DescriptionAbexinostat belongs to the class of organic compounds known as benzofurans. These are organic compounds containing a benzene ring fused to a furan. Furan is a five-membered aromatic ring with four carbon atoms and one oxygen atom. Based on a literature review very few articles have been published on Abexinostat. This compound has been identified in human blood as reported by (PMID: 31557052 ). Abexinostat is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Abexinostat 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.
