EF24 inhibited liver cancer cell proliferation.

<p>(<b>A</b>). The topological structures of curcumin (diferuloylmethane) and EF24 (diphenyl difluoroketone). (<b>B</b>). EF24 treatment on proliferation of PLC/PRF/5, SK-HEP-1, Hep3B, HepG2, Huh 7 and LO2 cells. These cells were incubated with increasing doses of EF24 (0.5–8 µmol/L) for 48-h and 72-h periods and analyzed for cell proliferation using cell counting kit-8 assay.
