Metabolite Identification
Common NameWithanolide 1
Description15-[1-(4,5-dimethyl-6-oxo-3,6-dihydro-2H-pyran-2-yl)-1-hydroxyethyl]-6-hydroxy-2,16-dimethyl-3-oxo-8-oxapentacyclo[9.7.0.0²,⁷.0⁷,⁹.0¹²,¹⁶]octadec-4-en-10-yl acetate belongs to the class of organic compounds known as withanolides and derivatives. These are c28 steroids structurally characterized by an ergostane skeleton usually functionalized at carbons 1, 22 and 26 to form a lactone ring. 15-[1-(4,5-dimethyl-6-oxo-3,6-dihydro-2H-pyran-2-yl)-1-hydroxyethyl]-6-hydroxy-2,16-dimethyl-3-oxo-8-oxapentacyclo[9.7.0.0²,⁷.0⁷,⁹.0¹²,¹⁶]octadec-4-en-10-yl acetate is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Withanolide 1 is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Withanolide 1 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.
