Abstract

Four new withanolides (2-5), together with 4β,7β,20-trihydroxy-1-oxowitha-2,5,24-trienolide (1), were isolated from the aerial parts of Eriolarynx iochromoides. The antiproliferative activity of all compounds purified from E. iochromoides together with four withaphysalins and four physangulidines isolated previously from three Deprea species were evaluated against human solid tumor cell lines. Four withanolides showed antiproliferative activity comparable in potency to cisplatin. Selectivity toward Cancer cells and interaction with P-glycoprotein of the active withanolides were evaluated.
