New series of [1,2,4]triazolo[4,3-a]quinoxalin-4(5H)-one and [1,2,4]triazolo[4,3-a]quinoxaline derivatives have been designed, synthesized, and biologically assessed for their anti-proliferative activities against two selected tumor cell lines MCF-7 and HepG2. Comparing to sorafenib (IC50 = 2.17 ± 0.13 and 3.51 ± 0.21 µM against MCF-7 and HepG2, respectively), compound 25d, 25e, 25i, and 27e exhibited
设计、合成了新系列的[1,2,4]三唑并[4,3 - a ]喹喔啉-4(5 H )-one和[1,2,4]三唑并[4,3- a ]喹喔啉衍生物,并对它们对两种选定的肿瘤细胞系 MCF-7 和 HepG2 的抗增殖活性进行了生物学评估。与索拉非尼相比( 分别对 MCF-7 和 HepG2 的IC 50 = 2.17 ± 0.13 和 3.51 ± 0.21 µM),化合物25d、25e、25i和27e对具有 IC 50的检查细胞系表现出最高的活性值从 4.1 ± 0.4 扩展到 11.7 ± 1.1 µM。此外,评估了所有合成化合物的 VEGFR-2 抑制活性,作为其抗增殖活性的潜在机制。化合物25d、25e、25i和27e对 VEGFR-2 激酶显示出显着的抑制效率,IC 50值范围为 3.4 ± 0.3 至 6.8 ± 0.5 nM。令人着迷的是,VEGFR-2 抑制试验的结果与细胞毒性
