Metabolite Identification

Common Name

3',4',5',5,7-Pentamethoxyflavone

Description

3',4',5',5,7-Pentamethoxyflavone belongs to the class of organic compounds known as 7-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C7 atom of the flavonoid backbone. Thus, 3',4',5',5,7-pentamethoxyflavone is considered to be a flavonoid. Based on a literature review a significant number of articles have been published on 3',4',5',5,7-Pentamethoxyflavone. This compound has been identified in human blood as reported by (PMID: 31557052 ). 3',4',5',5,7-pentamethoxyflavone is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 3',4',5',5,7-Pentamethoxyflavone 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.
