Novel analogs of epothilone A, epothilone B, and epothilone C are synthesized by Stille coupling thazole-stannanes to macrolactone intermediates. The synthetic epothilone analogs selectively prevent mitosis in cancer cells through the induction and stabilization of microtubulin assembly. Selected synthetic epothilone analogs are demonstrated to have greater bioactivity than their corresponding native compound.
