  with the IC50 value of 0.18 μM against HT29 cells, which was significantly better than that of the reference drugs shikonin and CA-4. What's more, 6c could inhibit tubulin polymerization and compete with [3H] colchicine in binding to tubulin.

  设计并合成了一系列新的紫草素-苯并[b]呋喃衍生物作为微管蛋白聚合抑制剂，并对其生物学活性进行了评估。大多数化合物显示出与紫草素相当的抗癌细胞增殖活性，同时对非癌细胞具有较低的细胞毒性。其中，化合物6c对HT29细胞显示出强大的抗癌活性，IC50值为0.18μM，显着优于参考药物紫草素和CA-4。而且，6c可以抑制微管蛋白聚合，并与[3H]秋水仙碱竞争与微管蛋白的结合。进一步的生物学研究表明6c可以诱导细胞凋亡并使细胞线粒体去极化，调节HT29细胞中凋亡相关蛋白的表达。除了，6c激活了HT29细胞在G2 / M期的细胞周期停滞，并影响了细胞周期相关蛋白的表达。此外，6c显示出对细胞迁移和管形成的有效抑制，这有助于抗血管生成。这些结果促使我们将6c视为潜在的微管蛋白聚合抑制剂，值得进一步研究。
