In order to find high-efficiency antitumor drugs, a series of 2,4,6-trisubstituted pyrimidine derivatives containing benzothiazole moiety were designed, synthesized and evaluated for antitumor activities against four cancer cells (EC-109, human esophageal cancer cells; MGC-803, human gastric cancer cells; PC-3, human prostate cancer cells; HepG-2, human liver cancer cells), GES-1 (human normal gastric mucosal epithelial cells), and HEEC (human normal esophagus) using thiazolyl blue (MTT) method. The results showed that some compounds exhibited moderate to strong antitumor activities against MGC-803 and PC-3 cells. Among them, 2-(((4-(4-(pyridin-2-yl)piperazin-1-yl)-6-(trifluoromethyl)pyrimidin-2-yl)-thio)methyl)benzo[d]thiazole (13h) and 2-(((4-(4-(pyrimidin-2-yl)piperazin-1-yl)-6-(trifluoromethyl)pyrimidin-2-yl)thio)-methyl)benzo[d]thiazole (13i) showed the most potent antitumor activities against PC-3 cells with IC50 values of 3.82 and 2.29 μmol/L, respectively. The toxicities of compounds 13h and 13i to GES-1 cells were significantly lower than the positive control 5-fluorouracil.
