The present invention provides an efficient synthetic strategy for the preparation of analogs that incorporate important structural elements of the marine natural product curacin A, the compositions and various uses of the compositions. The most active of these compounds at nanomolar concentrations inhibit tubulin polymerization, show growth inhibition activity, inhibited colchicines binding to tubulin and block mitotic progression. The compounds of the present invention represent some of the most potent synthetic curacin A analogs synthesized, with an activity profile rivaling that of the natural product despite the simplified structure, greater water solubility, and increased chemical stability.
本发明提供了一种有效的合成策略,用于制备包含海洋天然产物Curacin A的重要结构元素的类似物,以及这些类似物的组成和各种用途。其中,纳摩尔浓度下最活跃的化合物抑制微管聚合,显示生长抑制活性,抑制秋水仙碱结合到微管并阻碍有丝分裂进程。尽管化合物的结构简化、水溶性增加和化学稳定性提高,但本发明的化合物代表了一些最强效的合成Curacin A类似物之一,其活性谱与天然产物相媲美。
