Metabolite Identification
Common Name4-[(2-Cyclobutylimidazo[4,5-b]pyrazin-3-yl)methyl]-7,8-difluoro-1H-quinolin-2-one
DescriptionKD7332, also known as klyp 961, belongs to the class of organic compounds known as hydroquinolones. Hydroquinolones are compounds containing a hydrogenated quinoline bearing a ketone group. Based on a literature review a significant number of articles have been published on KD7332. This compound has been identified in human blood as reported by (PMID: 31557052 ). 4-[(2-cyclobutylimidazo[4,5-b]pyrazin-3-yl)methyl]-7,8-difluoro-1h-quinolin-2-one is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4-[(2-Cyclobutylimidazo[4,5-b]pyrazin-3-yl)methyl]-7,8-difluoro-1H-quinolin-2-one 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.
