Cytotoxic effects of 5-FU or PTX, CLZ, CPP2 and CPP2–thiazole conjugates on the viability of HT-29 (A) and PC-3 (B) cells, respectively. Cell viability was assessed by MTT assay after 48 h of exposure to each treatment. The results are expressed in the percentage of cell viability relative to untreated control cells. *, **, *** and **** indicate p < 0.05, p < 0.01, p < 0.001 and p < 0.0001, respectively, when compared with 5-FU or PTX. All data are presented as the mean ± SEM of three independent experiments.
