Metabolite Identification
Common Name2-[(4s)-6-(4-Chlorophenyl)-8-Methoxy-1-Methyl-4h-[1,2,4]triazolo[4,3-A][1,4]benzodiazepin-4-Yl]-N-Ethylacetamide
Description2-[(4s)-6-(4-Chlorophenyl)-8-Methoxy-1-Methyl-4h-[1,2,4]triazolo[4,3-A][1,4]benzodiazepin-4-Yl]-N-Ethylacetamide, also known as i-bet compound or molibresib besylate, belongs to the class of organic compounds known as 1,4-benzodiazepines. These are organic compounds containing a benzene ring fused to a 1,4-azepine. Based on a literature review very few articles have been published on 2-[(4s)-6-(4-Chlorophenyl)-8-Methoxy-1-Methyl-4h-[1,2,4]triazolo[4,3-A][1,4]benzodiazepin-4-Yl]-N-Ethylacetamide. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-[(4s)-6-(4-chlorophenyl)-8-methoxy-1-methyl-4h-[1,2,4]triazolo[4,3-a][1,4]benzodiazepin-4-yl]-n-ethylacetamide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-[(4s)-6-(4-Chlorophenyl)-8-Methoxy-1-Methyl-4h-[1,2,4]triazolo[4,3-A][1,4]benzodiazepin-4-Yl]-N-Ethylacetamide 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.
