Metabolite Identification
Common NameMitozolomide
Description3-(2-chloroethyl)-4-oxo-3H,4H-imidazo[4,3-d][1,2,3,5]tetrazine-8-carboxamide belongs to the class of organic compounds known as imidazotetrazines. These are organic polycyclic compounds containing an imidazole ring fused to a tetrazine ring. Imidazole is 5-membered ring consisting of three carbon atoms, and two nitrogen centers at the 1- and 3-positions. Tetrazine is a six-membered aromatic heterocycle made up of four nitrogen atoms and a two carbon atoms. Based on a literature review very few articles have been published on 3-(2-chloroethyl)-4-oxo-3H,4H-imidazo[4,3-d][1,2,3,5]tetrazine-8-carboxamide. This compound has been identified in human blood as reported by (PMID: 31557052 ). Mitozolomide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Mitozolomide 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.
