potencies against all cell lines compared to sorafenib (IC50 = 5.47–7.26 μM). Dual EGFR/VEGFR-2 inhibitory activities of the most active analogues (4, 11, and 20) were investigated. Compound 4 showed comparable EGFR/VEGFR-2 inhibitory activity to the used control drugs. Flow cytometric analysis indicates that the most potent analogue 4 stopped the cell cycle at the G1 phase and induced 46.53% total apoptosis
单分子的双重靶向已成为一种有前景的抗癌策略。在这项研究中,合成了一组新的2-thioquinazolin-4(3 H )-ones作为潜在的抗癌替代物,具有EGFR/VEGFR-2激酶双重抑制活性。针对一组四种癌细胞系评估了新合成的候选物4-27的抗肿瘤效力。准备好的候选药物4-27显示出与标准药物索拉非尼相当的活性。例如,与索拉非尼 (IC 50 = 5.47–7.26 μM) 相比,化合物4 (IC 50 = 1.50–5.86 μM) 和化合物20 (IC 50 = 4.42–6.39 μM) 对所有细胞系均表现出优异的效力。研究了最活跃的类似物( 4、11和20 )的双重 EGFR/VEGFR-2抑制活性。化合物4显示出与所用对照药物相当的EGFR/VEGFR-2抑制活性。流式细胞分析表明,最有效的类似物4将细胞周期终止于 G1 期,并诱导 HCT-116 细胞 46.53% 的总细胞凋亡,这比未处理的细胞(2
