| Description | N-(7-((2R,3R,4S,5R)-3,4-Dihydroxy-5-methoxy-6,6-dimethyl-tetrahydro-2H-pyran-2-yloxy)-8-methyl-2-oxo-2H-chromen-3-yl)acetamide, also known as ku-32 compound, belongs to the class of organic compounds known as coumarin glycosides. These are aromatic compounds containing a carbohydrate moiety glycosidically bound to a coumarin moiety. Based on a literature review very few articles have been published on N-(7-((2R,3R,4S,5R)-3,4-Dihydroxy-5-methoxy-6,6-dimethyl-tetrahydro-2H-pyran-2-yloxy)-8-methyl-2-oxo-2H-chromen-3-yl)acetamide. This compound has been identified in human blood as reported by (PMID: 31557052 ). N-(7-((2r,3r,4s,5r)-3,4-dihydroxy-5-methoxy-6,6-dimethyl-tetrahydro-2h-pyran-2-yloxy)-8-methyl-2-oxo-2h-chromen-3-yl)acetamide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically N-(7-((2R,3R,4S,5R)-3,4-Dihydroxy-5-methoxy-6,6-dimethyl-tetrahydro-2H-pyran-2-yloxy)-8-methyl-2-oxo-2H-chromen-3-yl)acetamide 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. |
