3a and 3i showed comparable cytotoxic activity with IC50 values of 1.22 and 1.24 μM compared to the reference drugs (IC50 = 0.932, 1.13 μM). Compound 3i was found to be the most effective VEGFR-2 inhibitor using in vitro testing of the synthesized compounds, with nearly 3-fold higher activity than Sorafenib (30 nM), with IC50 8.93 nM. Compound 3i significantly stimulated total apoptotic prostate cancer
由于VEGFR-2在肿瘤生长、血管生成和转移中发挥着至关重要的作用,因此它是癌症治疗的潜在靶点。在这项工作中,合成了一系列 3-苯基-4-(2-取代的苯基亚肼基)-1 H -吡唑-5(4 H )-酮 ( 3a–l ),并研究了它们对 PC-3 人的细胞毒性癌细胞系与作为参考药物的多柔比星和索拉非尼进行比较。与参比药物相比,两种化合物3a和3i显示出相当的细胞毒活性,IC 50值为 1.22 和 1.24 μM(IC 50 = 0.932、1.13 μM)。体外研究发现化合物3i是最有效的 VEGFR-2 抑制剂对合成的化合物进行测试,其活性比索拉非尼 (30 nM) 高近 3 倍,IC 50 8.93 nM。化合物3i显着刺激总凋亡性前列腺癌细胞死亡 55.2 倍(34.26%,对照的 0.62%),使细胞周期停滞在 S 期。参与细胞凋亡的基因也受到影响,促细胞凋亡基因上调,抗细胞凋亡基因
