According to a study published by "BMC complementary medicine and therapies", Piptadeniastrum africanum stembark (PASB) showed the highest cytotoxicity on brine shrimps with an LC50 of 1.58 μg/mL compared to vincristine sulphate which had an LC50 of 2.24 μg/mL. In cell viability assays, the extracts produced significant (p < 0.05) growth inhibitory effects against all tested cell lines in a dose-dependent manner. The PASB extract exhibited a 2-fold selectivity toward MCF-7 cancer cells relative to normal lung fibroblast (MRC-5) cells. This extract also significantly inhibited cell migration and colony formation in MCF-7-treated cells in dose-dependent manners. Considerable amounts of phenolics, flavonoids, and proanthocyanidins were detected in the extracts, advocating for the development of PASB as a potential chemotherapeutic agent.
