In the search for new derivatives with anticancer activity that are able to induce a selective pro-apoptotic mechanism in cancer cells, we have designed, synthesized, and evaluated a series of new 2-(alkylsulfanyl)-N-alkylpyrido[2,3-d]pyrimidine-4-amine derivatives as cytotoxic and apoptosis inducers. The potential antitumor activity of the compounds was evaluated in vitro by examining their cytotoxic effects against human breast, colon, and bladder cancer-cell lines.
The IC(50)values of the compounds that showed cytotoxic activity were calculated. The cytotoxic compounds were then tested for their ability to induce caspase-3 activation and nuclear-chromatin degradation. Some compounds, such as 6c, 6d, 6e, 6j, 6o, and 6p, show significant in-vitro cytotoxicity in at least two of the three tested cell lines, induced apoptosis, and also produced a rapid dose-dependent increase in the caspase-3 level in some of the cell lines tested. In order to test the selectivity of the compounds, two non-tumoral human cell lines were used. Several compounds of the did not show cytotoxicity in these cell lines.
