Metabolite Identification
Common Name2H-Benzo(a)quinolizin-2-ol, 2-ethyl-1,3,4,6,7,11b-hexahydro-9,10-dimethoxy-3-(2-methylpropyl)-
Description2-ethyl-9,10-dimethoxy-3-(2-methylpropyl)-1H,2H,3H,4H,6H,7H,11bH-pyrido[2,1-a]isoquinolin-2-ol belongs to the class of organic compounds known as tetrahydroisoquinolines. These are tetrahydrogenated isoquinoline derivatives. Based on a literature review very few articles have been published on 2-ethyl-9,10-dimethoxy-3-(2-methylpropyl)-1H,2H,3H,4H,6H,7H,11bH-pyrido[2,1-a]isoquinolin-2-ol. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2h-benzo(a)quinolizin-2-ol, 2-ethyl-1,3,4,6,7,11b-hexahydro-9,10-dimethoxy-3-(2-methylpropyl)- is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2H-Benzo(a)quinolizin-2-ol, 2-ethyl-1,3,4,6,7,11b-hexahydro-9,10-dimethoxy-3-(2-methylpropyl)- 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.
