Methyl 6,7-dimethoxy-4-ethyl-beta-carboline-3-carboxylate

Description

Methyl 6,7-dimethoxy-4-ethyl-beta-carboline-3-carboxylate belongs to the class of organic compounds known as beta carbolines. Beta carbolines are compounds containing a 9H-pyrido[3,4-b]indole moiety. Based on a literature review a significant number of articles have been published on Methyl 6,7-dimethoxy-4-ethyl-beta-carboline-3-carboxylate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Methyl 6,7-dimethoxy-4-ethyl-beta-carboline-3-carboxylate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Methyl 6,7-dimethoxy-4-ethyl-beta-carboline-3-carboxylate 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.
