Using methylated pyrroloxicam as a starting material and following the principles of drug design such as bioisosterism and active site binding, we designed and synthesized ten structurally novel target compounds, whose structures were characterized by 1H NMR and MS analysis. The in vitro antitumor activity of these title compounds was evaluated by measuring their inhibitory activity against pancreatic cancer cells Capan-1, leukemia cells L1210, and human liver cancer cells SMMC-7721. The results showed that compound 6f (IC50=4.8±0.5 μmol/L) exhibited good inhibitory activity against Capan-1 pancreatic cancer cells, that compound 6b (IC50=2.6±0.3 μmol/L) showed good inhibitory activity against L1210 leukemia cells, and that compound 6c (IC50=2.1±0.2 μmol/L) displayed good inhibitory activity against SMMC-7721 human liver cancer cells. These preliminary results from the antitumor activity experiments suggest that the introduction of benzothiazine derivatives plays a certain role in enhancing the antitumor activity of this class of compounds.
