Common Name(6r)-6-[(1r)-1-[(1r,3as,3bs,5r,5ar,9ar,9bs,11as)-5,5a-dihydroxy-9a,11a-dimethyl-9-oxo-1h,2h,3h,3ah,3bh,4h,5h,6h,9bh,10h,11h-cyclopenta[a]phenanthren-1-yl]-2-hydroxyethyl]-3,4-dimethyl-5,6-dihydropyran-2-one
DescriptionWithametelin D 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. (6r)-6-[(1r)-1-[(1r,3as,3bs,5r,5ar,9ar,9bs,11as)-5,5a-dihydroxy-9a,11a-dimethyl-9-oxo-1h,2h,3h,3ah,3bh,4h,5h,6h,9bh,10h,11h-cyclopenta[a]phenanthren-1-yl]-2-hydroxyethyl]-3,4-dimethyl-5,6-dihydropyran-2-one is found in Datura metel. Based on a literature review very few articles have been published on Withametelin D.
