Metabolite Identification
Common Name4-(2-Aminoethyl)benzenesulfonyl fluoride
Description4-(2-Aminoethyl)benzenesulfonyl fluoride, also known as AEBSF or pefabloc, belongs to the class of organic compounds known as phenethylamines. Phenethylamines are compounds containing a phenethylamine moiety, which consists of a phenyl group substituted at the second position by an ethan-1-amine. Based on a literature review very few articles have been published on 4-(2-Aminoethyl)benzenesulfonyl fluoride. This compound has been identified in human blood as reported by (PMID: 31557052 ). 4-(2-aminoethyl)benzenesulfonyl fluoride is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4-(2-Aminoethyl)benzenesulfonyl fluoride 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.
