Pregnane, coumarin and lupane derivatives and cytotoxic constituents from Helicteres angustifolia.
2alpha,7beta,20alpha-Trihydroxy-3beta,21-dimethoxy-5-pregnene (1), 6,7,9alpha-trihydroxy-3,8,11alpha-trimethylcyclohexo-[d,e]-coumarin (2), 3beta-hydroxy-27-benzoyloxylup-20(29)-en-28-oic acid (3), and 3beta-hydroxy-27-benzoyloxylup-20(29)-en-28-oic acid methyl ester (4), along with 24 known compounds were isolated and structurally characterized from roots and aerial parts of Helicteres angustifolia (Sterculiaceae). In a preliminary bioassay, the two cucurbitacin derivatives, cucurbitacin D and J exhibited significant inhibitory activities against the growth of both hepatocellular carcinoma BEL-7402 cells and malignant melanoma SK-MEL-28 cells in vitro.
