Description

9,10-dihydroxy-8,8-dimethyl-2H,8H,9H,10H-pyrano[2,3-h]chromen-2-one 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 9,10-dihydroxy-8,8-dimethyl-2H,8H,9H,10H-pyrano[2,3-h]chromen-2-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). (+)-cis-khellactone is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (+)-cis-Khellactone 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.
