A new series of bis([1,2,4]triazolo)[4,3-a:3',4'-c]quinoxaline derivatives were designed and synthesized to have the main essential pharmacophoric features of VEGFR-2 inhibitors. VEGFR-2 inhibitory activities were assessed for the designed compounds. In addition, cytotoxic activity was evaluated for all derivatives against two human cancer cell lines namely, HepG-2 and MCF-7. The most cytotoxic compound
设计并合成了一系列新的双([1,2,4]三唑并)[4,3- a :3',4'- c ]喹喔啉衍生物,它们具有 VEGFR-2 抑制剂的主要基本药效特征。评估了设计化合物的 VEGFR-2 抑制活性。此外,评估了所有衍生物对两种人类癌细胞系,即 HepG-2 和 MCF-7 的细胞毒活性。对细胞毒性最强的化合物20h进行了进一步的生物学研究,包括细胞周期、细胞凋亡、caspase-3、caspase-9、BAX 和 Bcl-2 分析。进行了不同的计算机模拟研究,如对接、ADMET 和毒性。结果表明,化合物 20b、20e、20h 和 20m 显示出有希望的 VEGFR-2 抑制活性,IC 50 值分别为 5.7、6.7、3.2 和 3.1 µM。此外,与索拉非尼(分别针对 HepG2 和 MCF-7 的IC 50 = 2.17 和 3.43 µM)相比,这些有前途的成员对两种细胞系表现出最高的抗增殖活性,IC
