Metabolite Identification
Common NameAzepexole
DescriptionAzepexole, also known as b HT-933 or azepoxol, belongs to the class of organic compounds known as azepines. These are organic compounds containing an unsaturated seven-member heterocycle with one nitrogen atom replacing a carbon atom. Based on a literature review very few articles have been published on Azepexole. This compound has been identified in human blood as reported by (PMID: 31557052 ). Azepexole is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Azepexole 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.
