Metabolite Identification
Common Name8-Azaguanine
Description8-Azaguanine, also known as guanazol or pathocidin, belongs to the class of organic compounds known as triazolopyrimidines. These are polycyclic aromatic compounds containing triazole ring fused to a pyrimidine ring. Triazole is a five-membered ring consisting of two carbon atoms and three nitrogen atoms. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. 8-Azaguanine exists in all living organisms, ranging from bacteria to humans. 8-Azaguanine 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 very few articles have been published on 8-Azaguanine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 8-azaguanine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 8-Azaguanine 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.
