a Effect of concentration-dependent activity of ß-lap on the cell viability of Cal33 cells. b Cytotoxic effect of individual and combination with second chemotherapeutic agent, 5-FU at 3 different concentrations of 5–20 μg/ml, respectively. The cell viability was evaluated by MTT assay after 24 h of incubation. c Western blot analysis of NQO1 and Bcl-2 protein expression after treatment with individual and combination of 5-FU and ß-lap
