palladium-mediated coupling and macrolactonization. The synthesis of these compounds is described and their in vitro biological activity is discussed with respect to their interactions with the tubulin/microtubule system and the inhibition of human cancer cell proliferation. The additional functional groups may be used to synthesize conjugates of epothilone derivatives with a variety of tumor-targeting moieties
埃博洛酮是有效的抗增殖剂,已成为成功发现抗癌药物的先导结构。然而,它们对肿瘤细胞的选择性的增加将极大地受益于它们的治疗功效,这可以通过与肿瘤靶向部分缀合来实现。使用基于钯介导的偶联和大环内酯化的策略合成了三个带有各种功能化的苯并咪唑侧链的新型埃坡霉素类似物。描述了这些化合物的合成,并讨论了它们与微管蛋白/微管系统的相互作用以及对人类癌细胞增殖的抑制作用。
