Abstract
The ethyl acetate-soluble fraction from a MeOH extract of the roots of Ferula varia gave six new sesquiterpene lactones (1-6) and five known sesquiterpenes (7-11). Their structures were established on the basis of spectroscopic evidence. The cytotoxic activities of 1-11 were evaluated against selected human cancer cell lines. Compound 4 showed significant selective cytotoxicity against multidrug-resistant cancer cells (KB-C2). The cytotoxicities of compounds 1, 3, 5, 8, and 11 against KB-C2 cells were enhanced in the presence of nontoxic concentrations of colchicine.Entities:
