Metabolite Identification
Common NameEmapunil
DescriptionEmapunil belongs to the class of organic compounds known as purinones. These are purines in which the purine moiety bears a C=O group. 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 Emapunil. This compound has been identified in human blood as reported by (PMID: 31557052 ). Emapunil is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Emapunil 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.
