(1r,2r,4s,6r,8s,9z,11s)-8-hydroxy-4,9-dimethyl-14-methylidene-13-oxo-5,12-dioxatricyclo[9.3.0.0⁴,⁶]tetradec-9-en-2-yl (2e)-2-methylbut-2-enoate

Description

Heliangin 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. (1r,2r,4s,6r,8s,9z,11s)-8-hydroxy-4,9-dimethyl-14-methylidene-13-oxo-5,12-dioxatricyclo[9.3.0.0⁴,⁶]tetradec-9-en-2-yl (2e)-2-methylbut-2-enoate is found in Calea jamaicensis and Helianthus annuus. (1r,2r,4s,6r,8s,9z,11s)-8-hydroxy-4,9-dimethyl-14-methylidene-13-oxo-5,12-dioxatricyclo[9.3.0.0⁴,⁶]tetradec-9-en-2-yl (2e)-2-methylbut-2-enoate was first documented in 2005 (PMID: 15921421). Based on a literature review a small amount of articles have been published on Heliangin (PMID: 35053238) (PMID: 28095354).
