Metabolite Identification
Common NameEthaverine
Description1-[(3,4-diethoxyphenyl)methyl]-6,7-diethoxyisoquinoline, also known as ethquinol, belongs to the class of organic compounds known as benzylisoquinolines. These are organic compounds containing an isoquinoline to which a benzyl group is attached. Based on a literature review very few articles have been published on 1-[(3,4-diethoxyphenyl)methyl]-6,7-diethoxyisoquinoline. This compound has been identified in human blood as reported by (PMID: 31557052 ). Ethaverine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Ethaverine 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.
