Metabolite Identification
Common Name2-Amino-6-methoxypurine
Description2-Amino-6-methoxypurine, also known as O-(6)-methylguanine or 6-methoxy-1H-purine-2-amine, belongs to the class of organic compounds known as hypoxanthines. Hypoxanthines are compounds containing the purine derivative 1H-purin-6(9H)-one. Purine is a bicyclic aromatic compound made up of a pyrimidine ring fused to an imidazole ring. Based on a literature review a small amount of articles have been published on 2-Amino-6-methoxypurine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-amino-6-methoxypurine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-Amino-6-methoxypurine 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.
