Metabolite Identification
Common Name3,4-Dehydrocilostazol
Description6-[4-(1-cyclohexyl-1H-1,2,3,4-tetrazol-5-yl)butoxy]-1,2-dihydroquinolin-2-one 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 very few articles have been published on 6-[4-(1-cyclohexyl-1H-1,2,3,4-tetrazol-5-yl)butoxy]-1,2-dihydroquinolin-2-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). 3,4-dehydrocilostazol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 3,4-Dehydrocilostazol 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.
