Induction of apoptosis by beta-diketones in human tumor cells.


A variety of beta-diketones were evaluated for their cytotoxic profiles against oral human normal and tumor cells. Among 22 compounds (BD1-22) tested, the cytotoxicity of 3-formylchromone (BD17) (CC50=7.8 microg/mL) against human oral squamous cell carcinoma (HSC-2) cells was higher than that of curcumin (CC50=23.6 microg/mL). Tumor cell-specific… (More)
