methyl (3ar,4r,10r,11ar)-10-(hydroxymethyl)-3-methylidene-4-[(2-methylpropanoyl)oxy]-2-oxo-3ah,4h,5h,8h,9h,10h,11h,11ah-cyclodeca[b]furan-6-carboxylate

Description

4-Epi-Melnerin A belongs to the class of organic compounds known as germacranolides and derivatives. These are sesquiterpene lactones with a structure based on the germacranolide skeleton, characterized by a gamma lactone fused to a 1,7-dimethylcyclodec-1-ene moiety. methyl (3ar,4r,10r,11ar)-10-(hydroxymethyl)-3-methylidene-4-[(2-methylpropanoyl)oxy]-2-oxo-3ah,4h,5h,8h,9h,10h,11h,11ah-cyclodeca[b]furan-6-carboxylate is found in Melampodium leucanthum. Based on a literature review very few articles have been published on 4-epi-Melnerin A.
