Twenty-two 7-fluoro (or 8-methoxy)-4-anilinoquinolines compounds were designed and synthesized as potentially potent and selective antitumor inhibitors. All the prepared compounds were evaluated for their in vitro antiproliferative activities against the HeLa and BGC823 cell lines. Ten compounds (1a–g; 2c; 2e and 2i) exhibited excellent antitumor activity superior to that of gefitinib. Among the ten compounds; seven (1a–c; 1e–1g and 2i) displayed excellent selectivity for BGC823 cells. In particular; 1f and 2i exhibited potent cytotoxic activities against HeLa cells and BGC823 cells with better IC50 values than gefitinib.
设计并合成了二十二种7-
氟(或8-甲氧基)-4-苯
氨基
喹啉化合物,作为潜在的强效和选择性的抗肿瘤
抑制剂。所有合成的化合物均在体外评估了其对HeLa和BGC823
细胞系的抗增殖活性。十种化合物(1a–g;2c;2e和2i)表现出优于
吉非替尼的优良抗肿瘤活性。在这十种化合物中,有七种(1a–c;1e–1g和2i)对BGC823细胞表现出优异的选择性。特别是,1f和2i对HeLa细胞和BGC823细胞展现出强效的细胞毒活性,其IC50值优于
吉非替尼。
