derivatives were evaluated to assess their anticancer activity against three human cancer cell lines, including HepG2, HCT-116, and MCF-7. The results of the in vitro anticancer evaluation study revealed the moderate to excellent cytotoxicity of 6c, 6e, 6g, and 7b, with IC50 values in the low micromolar range. The inhibitory activity of VEGFR-2 was investigated for 16 of the designed compounds. The enzyme
在设计的化合物中,新的接头以片段的形式插入,该片段具有经验证的 VEGFR-2 抑制潜力,包括 α、β-不饱和酮片段、吡唑和嘧啶。此外,新的远端疏水部分连接到这些接头上,预计会增加与 VEGFR-2 的疏水相互作用,从而增加亲和力。这些结构优化使我们将新型二氢吡唑衍生物 6e 鉴定为有前途的命中分子。评估了所有新衍生物以评估它们对三种人类癌细胞系的抗癌活性,包括 HepG2、HCT-116 和 MCF-7。体外抗癌评估研究的结果显示,中度至极好的细胞毒性6c、6e、6g和7b, IC 50值在低微摩尔范围内。研究了 16 种设计化合物的 VEGFR-2 抑制活性。将新化合物的酶测定结果与索拉非尼作为参考 VEGFR-2 抑制剂的结果进行了比较。所得结果表明我们的衍生物是有效的 VEGFR-2 抑制剂。最有效的衍生物6 c、6 e、6 g和7 b显示 IC 50值在 0.11–0.22 µM
