Metabolite Identification
Common NameDiaziquone
Descriptiondiaziquone, also known as AZQ or CI 904, belongs to the class of organic compounds known as p-benzoquinones. These are benzoquinones where the two C=O groups are attached at the 1- and 4-positions, respectively. Based on a literature review a significant number of articles have been published on diaziquone. This compound has been identified in human blood as reported by (PMID: 31557052 ). Diaziquone is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Diaziquone 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.
