Metabolite Identification

Common Name

N-Methyl-N-nitroso-1H-purin-6-amine

Description

N-Methyl-N-nitroso-1H-purin-6-amine, also known as N(6)-(methylnitroso)adenosine, belongs to the class of organic compounds known as 6-alkylaminopurines. 6-alkylaminopurines are compounds that contain an alkylamine group attached at the 6-position of a purine. Purine is a bicyclic aromatic compound made up of a pyrimidine ring fused to an imidazole ring. Based on a literature review very few articles have been published on N-Methyl-N-nitroso-1H-purin-6-amine. This compound has been identified in human blood as reported by (PMID: 31557052 ). N-methyl-n-nitroso-1h-purin-6-amine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically N-Methyl-N-nitroso-1H-purin-6-amine 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.
