Metabolite Identification
Common NameIsrib
Description2-(4-chlorophenoxy)-N-(4-{[2-(4-chlorophenoxy)-1-hydroxyethylidene]amino}cyclohexyl)ethanimidic acid 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 2-(4-chlorophenoxy)-N-(4-{[2-(4-chlorophenoxy)-1-hydroxyethylidene]amino}cyclohexyl)ethanimidic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Isrib is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Isrib 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.
