Common NameEthylhydrocupreine
Description(6-ethoxyquinolin-4-yl)({5-ethyl-1-azabicyclo[2.2.2]octan-2-yl})methanol belongs to the class of organic compounds known as cinchona alkaloids. These are alkaloids structurally characterized by the presence of the cinchonan skeleton, which consists of a quinoline linked to an azabicyclo[2.2.2]octane moiety. Based on a literature review very few articles have been published on (6-ethoxyquinolin-4-yl)({5-ethyl-1-azabicyclo[2.2.2]octan-2-yl})methanol. This compound has been identified in human blood as reported by (PMID: 31557052 ). Ethylhydrocupreine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Ethylhydrocupreine 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.
