Description

Eupachinilide C belongs to the class of organic compounds known as guaianolides and derivatives. These are diterpene lactones with a structure characterized by the presence of a gamma-lactone fused to a guaiane, forming 3,6,9-trimethyl-azuleno[4,5-b]furan-2-one or a derivative. (3ar,4r,6r,7r,9br)-6-(chloromethyl)-6,7-dihydroxy-9-methyl-3-methylidene-2-oxo-3ah,4h,5h,6ah,7h,9ah,9bh-azuleno[4,5-b]furan-4-yl (2e)-4-hydroxy-2-methylbut-2-enoate is found in Eupatorium chinense. (3ar,4r,6r,7r,9br)-6-(chloromethyl)-6,7-dihydroxy-9-methyl-3-methylidene-2-oxo-3ah,4h,5h,6ah,7h,9ah,9bh-azuleno[4,5-b]furan-4-yl (2e)-4-hydroxy-2-methylbut-2-enoate was first documented in 2004 (PMID: 15387644). Based on a literature review very few articles have been published on Eupachinilide C.
