A series of compounds bearing quinoline‐imidazole (8a–e, 9a–e, 10a–e, 11a–e, and 12a–e) not reported previously were designed and synthesized. The target compounds were evaluated for antitumor activity against A549, PC‐3, HepG2, and MCF‐7 cells by the MTT method, with NVP‐BEZ235 being the positive control. Most compounds showed moderate activity and compound 12a showed the best activity against HepG2
设计并合成了一系列以前未报道的含有
喹啉-
咪唑的化合物(8a-e、9a-e、10a-e、11a-e 和 12a-e)。通过M
TT方法评估目标化合物对A549、PC-3、HepG2和MCF-7细胞的抗肿瘤活性,
NVP-BEZ235为阳性对照。大多数化合物显示出中等活性,化合物 12a 对 HepG2、A549 和 PC-3 细胞显示出最佳活性,半数抑制浓度 (IC50) 值为 2.42 ± 1.02 µM、6.29 ± 0.99 µM 和 5.11 ± 1.00 µM,分别等于
NVP-BEZ235(0.54 ± 0.13 µM、0.36 ± 0.06 µM、0.20 ± 0.01 µM)。此外,12a 对
细胞系 WI-38(人胎肺成纤维细胞)的 IC50 值为 32.8 ± 1.23 µM,表明目标化合物对癌细胞具有选择性。所以,针对
PI3Kα 和 mTOR 评估了 11a 和 12a,以确定这些化合物是否通过
