inhibitor Indomethacin analogs exhibited more potent cancer cell growth inhibition and apoptosis inducing activities than the parental compound. The anti-proliferative mechanism investigation of the analogs revealed that they inhibited tubulin polymerization at high concentrations whereas enhanced polymerization at low concentrations. The two opposite activities might antagonize each other and impaired the
环氧合酶(COX)抑制剂吲哚美辛类似物比母体化合物显示出更有效的癌细胞生长抑制和凋亡诱导活性。对类似物的抗增殖机理研究表明,它们在高浓度下抑制微管蛋白的聚合,而在低浓度下则增强聚合。两种相反的活性可能彼此拮抗并最终损害了衍生物的抗增殖活性。在这项研究中,我们根据生成的结构活动关系(SAR)进一步进行了潜在客户优化。一种新的吲哚美辛衍生物化合物11 2-(4-(苄氧基)苯基)-N-(1-(4-溴苯甲酰基)-3-(2-(((2-(二甲氨基)乙基)氨基)-2-氧乙基)-2-甲基-1H-吲哚-5-基)乙酰胺}在亚微摩尔水平抑制一组癌细胞的增殖,其IC50值较高。进一步的研究表明,该化合物仅增强微管蛋白的聚合作用,并且是微管蛋白的稳定剂。
