isomeric methoxy substitutions on the indole ring. Additionally, analogues containing a trimethoxyphenyl group in place of the pyridinyl moiety were evaluated for anticancer activity. The results demonstrate that the location of the methoxy group can alter both the potency and the mechanism of cell death. Remarkably, changing the methoxy from the 5-position to the 6-position switched the biological activity
某些吲哚基-吡啶基-丙烯酮类似物杀死已经对常规治疗药物产生抗性的胶质母细胞瘤细胞。这些类似物中的一些诱导了一种新形式的非凋亡性细胞死亡,称为变态,而其他类似物则主要引起微管破坏。当存在一个简单的甲氧基时,对5-吲哚取代的容易获得对这两种类型的机理都至关重要。现在,我们报告吲哚环上异构甲氧基取代的合成和生物学效应。另外,评估了含有三甲氧基苯基代替吡啶基部分的类似物的抗癌活性。结果表明,甲氧基的位置可以改变效力和细胞死亡的机制。值得注意的是 将甲氧基从5位更改为6位可将生物学活性从诱导变色转变为破坏微管。后者可以代表具有潜在治疗用途的新型有丝分裂抑制剂的原型。
