Cyclooxygenase (COX) inhibitors Indomethacin and its structural analogs Sulindac exhibit cell growth inhibition and apoptosis inducing activities in various cancer cell lines via COX independent mechanisms. In this study, the molecular structures of Indomethacin and Sulindac were used as starting scaffolds to design novel analogs and their effects on the proliferation of human cancer cells were evaluated
环氧合酶(COX)抑制剂吲哚美辛及其结构类似物舒林酸通过COX独立机制在多种癌细胞系中表现出细胞生长抑制和凋亡诱导活性。在这项研究中,吲哚美辛和舒林酸的分子结构被用作起始支架来设计新的类似物,并评估了它们对人癌细胞增殖的影响。与吲哚美辛和舒林酸抑制癌细胞增殖(IC 50大于1 mM)相比,这些衍生物显示出显着增加的活性。尤其是,一种吲哚美辛类似物通过IC 50抑制了一系列癌细胞系的生长。大约为0.5 μM–3μM。机理研究表明,新的类似物实际上是微管蛋白抑制剂,尽管母体化合物吲哚美辛没有显示出任何微管蛋白抑制活性。微管蛋白聚合测定表明该化合物在高浓度下抑制微管蛋白组装,但在低浓度下促进该过程,这是非常独特的机制。使用分子对接模拟预测了该化合物在微管蛋白中的结合模式。
