Metabolite Identification
Common NameEtimizol
DescriptionEtimizol, also known as aethimizole or ethylnorantifeine, belongs to the class of organic compounds known as 2-heteroaryl carboxamides. 2-heteroaryl carboxamides are compounds containing a heteroaromatic ring that carries a carboxamide group. Based on a literature review very few articles have been published on Etimizol. This compound has been identified in human blood as reported by (PMID: 31557052 ). Etimizol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Etimizol 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.
