Metabolite Identification
Common NameStemRegenin 1
DescriptionStemRegenin 1 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 a significant number of articles have been published on StemRegenin 1. This compound has been identified in human blood as reported by (PMID: 31557052 ). Stemregenin 1 is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically StemRegenin 1 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.
