A potential microtubule destabilizing series of new thirty-five Pyrrol-2-one, Pyridazin-3(2H)-one and Pyridazin-3(2H)-one/oxime derivatives has been synthesized and tested for their antiproliferative activity against a panel of 60 human cancer cell lines. Compounds IVc, IVg and IVf showed a broad spectrum of growth inhibitory activity against cancer cell lines representing renal, cancer of lung, colon
一个潜在的微管不稳定系列新的 35 Pyrrol-2-one、Pyridazin-3(2 H )-one 和 Pyridazin-3(2 H )-one/肟衍生物已被合成并测试了它们对一组的抗增殖活性60 种人类癌细胞系。化合物IVc、IVg和IVf对代表肾癌、肺癌、结肠癌、中枢神经系统癌、卵巢癌和肾癌的癌细胞系显示出广谱的生长抑制活性。其中,发现化合物IVg对所测试的 9 个肿瘤亚组具有广谱抗肿瘤活性,在 GI 50水平上的选择性比率范围在 0.21 和 3.77 之间。体外分析揭示了所有活性化合物IVc、IVg和IVf 对微管蛋白聚合的抑制作用。对接研究的结果揭示了化合物IVc、IVf和IVg与微管蛋白中 CA-4 结合位点的良好拟合。与 CA-4 (-8.87 kcal/mol) 相比,这三种化合物对微管蛋白表现出高结合亲和力 (ΔG b = -12.49 至 -12.99 kcal
