Three new series of phenyl dihydropyridazinone derivatives 4b–8i have been designed, synthesized and evaluated for their anticancer activity against different cancer cell lines. Nine compounds showed strong inhibitory activity, among which compound 8b exhibited potent activity against PC-3 cell line with IC50 value of 7.83 µM in comparison to sorafenib (IC50 11.53 µM). Compounds 6a, 6c, 7f-h and 8a-d
已经设计,合成和评估了三个新系列的苯基二氢哒嗪酮衍生物4b – 8i对不同癌细胞系的抗癌活性。九种化合物显示出强大的抑制活性,其中化合物8b对PC-3细胞系表现出有效的活性,与索拉非尼(IC 50 11.53 µM)相比,IC 50值为7.83 µM 。进一步筛选化合物6a,6c,7f-h和8a-d的B-Raf抑制活性,其中七个化合物7f-h和8a-d在IC 50范围内显示出高的B-Raf抑制作用与索拉非尼(IC 50 44.05 nM)相比,分别为70.65–84.14 nM和24.97–44.60 nM 。在测试的化合物中,8b是最有效的B-Raf抑制剂,IC 50值为24.79 nM。用8b处理的MCF-7细胞的细胞周期分析显示,细胞周期停滞在G2-M期,具有明显的凋亡作用。进行了分子建模研究,以了解最具活性的合成化合物与B-Raf酶的结合模式。
