Metabolite Identification
Common NameFadrozole
Description4-{5H,6H,7H,8H-imidazo[1,5-a]pyridin-5-yl}benzonitrile belongs to the class of organic compounds known as imidazopyridines. These are organic polycyclic compounds containing an imidazole ring fused to a pyridine ring. Imidazole is 5-membered ring consisting of three carbon atoms, and two nitrogen centers at the 1- and 3-positions. Pyridine is a 6-membered ring consisting of five carbon atoms and one nitrogen center. Based on a literature review very few articles have been published on 4-{5H,6H,7H,8H-imidazo[1,5-a]pyridin-5-yl}benzonitrile. This compound has been identified in human blood as reported by (PMID: 31557052 ). Fadrozole is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Fadrozole 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.
