Metabolite Identification
Common Name6-Azauracil
Description6-azauracil belongs to the class of organic compounds known as 1,2,4-triazines. 1,2,4-triazines are compounds containing a triazine ring, which is a heterocyclic ring, similar to the six-member benzene ring but with three carbons replaced by nitrogen atoms, at ring positions 1, 2, and 4. 6-azauracil is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on 6-azauracil. This compound has been identified in human blood as reported by (PMID: 31557052 ). 6-azauracil is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 6-Azauracil 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.
