WZ35 inhibits cell proliferation of colon cells. A. Chemical structures of WZ35 and curcumin. B, C. Effects of WZ35 or curcumin on the proliferation of colon cancer cells. HCT116, SW620, or CT26 cells were incubated with increasing doses of WZ35 or curcumin (1.25-20 μM) for 24 h, respectively. Cell viability was determined by MTT assay and the IC₅₀ values were calculated.
