Metabolite Identification
Common NameCanthin-6-one
Descriptioncanthin-6-one belongs to the class of organic compounds known as indolonaphthyridine alkaloids. These are a numerous and relatively straightforward subgroup of the b-carbolines, e.g. Canthin-6-one, in which an additional C3 unit is attached between C-1 and the indole nitrogen to form an additional ring. The group includes a few dimeric examples, such as Haplophytine. canthin-6-one is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a small amount of articles have been published on canthin-6-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). Canthin-6-one is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Canthin-6-one 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.
