Metabolite Identification
Common Name(-)-Kawain
Description4-methoxy-6-(2-phenylethenyl)-5,6-dihydro-2H-pyran-2-one belongs to the class of organic compounds known as kavalactones. These are lactones, which is structurally characterized by a benzene ring and a pyranone moiety, linked to each other to form a 4-methoxy-6-(2-phenylethyl)-2H-pyran-2-one skeleton. Based on a literature review very few articles have been published on 4-methoxy-6-(2-phenylethenyl)-5,6-dihydro-2H-pyran-2-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). (-)-kawain is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (-)-Kawain 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.
