Abstract

Activity-guided fractionation of the stem bark of Annona senegalensis gave four bioactive ent-kaurenoids (1-4). Compound 2 showed selective and significant cytotoxicity for MCF-7 (breast cancer) cells (ED₅₀ 1.0 μg/mL), and 3 and 4 exhibited cytotoxic selectivity for PC-3 (prostate cancer) cells but with weaker potencies (ED₅₀ 17-18 μg/mL). The structure of the new compound, 3, was deduced from spectral evidence.
