The synthesis, cytotoxicity, inhibition of tubulin polymerization and anti-angiogenic effects of 15 analogs of 2-methoxyestradiol (1) are reported. The biological studies revealed that the position of nitrogen atom in the heterocyclic ring is important for inhibition of both tubulin polymerization and angiogenesis. The most potent inhibitors were compounds 11f and 13e, with a 6-substituted isoquinoline
报道了15种2-甲氧基雌二醇(1)类似物的合成,细胞毒性,微管蛋白聚合的抑制作用和抗血管生成作用。生物学研究表明,氮原子在杂环中的位置对于抑制微管蛋白聚合和血管生成均很重要。最有效的抑制剂是化合物11f和13e,在类固醇骨架的17位上带有6个取代的异喹啉环。此外,对于在10μM浓度下测试的类似物,观察到较低的雌激素活性。
