Metabolite Identification
Common NameCinnoline
DescriptionCinnoline, also known as 1,2-benzodiazine or benzopyridazine, belongs to the class of organic compounds known as cinnolines. These are organic aromatic compounds containing a benzene fused to a pyridazine ring. Based on a literature review a significant number of articles have been published on Cinnoline. This compound has been identified in human blood as reported by (PMID: 31557052 ). Cinnoline is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Cinnoline 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.
