Common NameVisnadin
Description10-(acetyloxy)-8,8-dimethyl-2-oxo-2H,8H,9H,10H-pyrano[2,3-h]chromen-9-yl 2-methylbutanoate belongs to the class of organic compounds known as angular pyranocoumarins. These are organic compounds containing a pyran (or a hydrogenated derivative) angularly fused to a coumarin moiety. Based on a literature review very few articles have been published on 10-(acetyloxy)-8,8-dimethyl-2-oxo-2H,8H,9H,10H-pyrano[2,3-h]chromen-9-yl 2-methylbutanoate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Visnadin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Visnadin 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.
