Metabolite Identification
Common Name(2R,4S,5R)-5-Ethyl-2-[(S)-hydroxy-(6-methoxyquinolin-4-yl)methyl]-1-azabicyclo[2.2.2]octan-5-ol
Description(2R,4S,5R)-5-Ethyl-2-[(S)-hydroxy-(6-methoxyquinolin-4-yl)methyl]-1-azabicyclo[2.2.2]octan-5-ol 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 (2R,4S,5R)-5-Ethyl-2-[(S)-hydroxy-(6-methoxyquinolin-4-yl)methyl]-1-azabicyclo[2.2.2]octan-5-ol. This compound has been identified in human blood as reported by (PMID: 31557052 ). (2r,4s,5r)-5-ethyl-2-[(s)-hydroxy-(6-methoxyquinolin-4-yl)methyl]-1-azabicyclo[2.2.2]octan-5-ol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (2R,4S,5R)-5-Ethyl-2-[(S)-hydroxy-(6-methoxyquinolin-4-yl)methyl]-1-azabicyclo[2.2.2]octan-5-ol 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.
