Compound K induces cell death in HCT-116 cells. (a) HCT-116 cell viability following treatment with the indicated concentrations of compound K for 24 h was assessed using the MTT assay. *Significantly different from untreated control (P<0.05). (b) HCT-116 and FHC cell viability at the indicated times was assessed in the presence of compound K (20 μg/ml) using the MTT assay. *Significantly different from FHC cells (P<0.05)
