A novel series of BPU analogues were synthesized and evaluated for antitumor activity. In particular, BPU sulfur analogues 6n and 7d were shown to possess up to10-fold increased potency, when compared to I (NSC-639829), against cancer cell lines. 6n was more effective than I in causing apoptosis of MCF-7 cells. When compared to other drugs with a similar mechanism of action, 6n retained significant ability to inhibit tubulin assembly, with an IC50 of 2.1 mu M.
