Three novel pyrazolo-[4,3-e][1,2,4]triazolopyrimidine derivatives (1, 2, and 3) were designed, synthesized, and evaluated for their in vitro biological activity. All three compounds exhibited different levels of cytotoxicity against cervical and breast cancer cell lines. However, compound 1 showed the best antiproliferative activity against all tested tumor cell lines, including HCC1937 and HeLa cells
设计、合成了三种新型吡唑并 [4,3-e][1,2,4] 三唑并嘧啶衍生物(1、2 和 3),并评估了它们的体外生物活性。所有三种化合物对宫颈癌细胞系和乳腺癌细胞系都表现出不同水平的细胞毒性。然而,化合物 1 对所有测试的肿瘤细胞系显示出最佳的抗增殖活性,包括 HCC1937 和 HeLa 细胞,它们表达高水平的野生型表皮生长因子受体 (EGFR)。蛋白质印迹分析表明,化合物 1 分别在 7 µM 和 11 µM 的浓度下抑制了乳腺癌和宫颈癌细胞中 EGFR、蛋白激酶 B (Akt) 和细胞外信号调节激酶 (Erk)1/2 的激活。EGFR对接实验的结果表明化合物1在EGFR的ATP结合位点结合。此外,化合物3(7-(4-溴苯基)-9-(吡啶-4-基)-7H-吡唑并[4,3-e][1,2,4]三唑并[1,5-c]的晶体结构嘧啶)通过单晶 X 射线分析确定。我们的工作代表了开发一系列针对 EGFR
