New bioactive diterpene polyesters from Euphorbia decipiens

J Nat Prod. 2003 Sep;66(9):1221-4. doi: 10.1021/np020186a.

Abstract

A reinvestigation with a modified extraction procedure of Euphorbia decipiens resulted in the isolation and structure elucidation of three new myrsinane-type diterpene esters (1-3). The structures of compounds 1-3 were elucidated by spectroscopic data interpretation. Compound 1 showed inhibitory activity against prolyl endopeptidase (PEP), whereas compound 2 exhibited DNA-damaging activity in a mutant yeast bioassay.
