Description4,7,8-trimethoxyfuro[2,3-b]quinoline belongs to the class of organic compounds known as furanoquinolines. Furanoquinolines are compounds containing a furan ring fused to a quinoline. 4,7,8-trimethoxyfuro[2,3-b]quinoline is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review very few articles have been published on 4,7,8-trimethoxyfuro[2,3-b]quinoline. This compound has been identified in human blood as reported by (PMID: 31557052 ). Skimmianine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Skimmianine 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.
