A series of 4‐(2‐fluorophenoxy)quinoline derivatives bearing the 4‐oxo‐1,4‐dihydroquinoline‐3‐carboxamide moiety were designed, synthesized, and evaluated for their in vitro antitumor activity against the H460, HT‐29, MKN‐45, U87MG, and SMMC‐7721 cancer cell lines. Most of the tested compounds showed potent activity and high selectivity toward the HT‐29 and MKN‐45 cell lines. Furthermore, compounds
设计、合成了一系列带有 4-oxo-1,4-dihydroquinoline-3-carboxamide 部分的 4-(2-fluorophenoxy)quinoline 衍生物,并评估了它们对 H460、HT-29、MKN 的体外抗肿瘤活性‐45、U87MG 和 SMMC-7721 癌细胞系。大多数测试化合物对 HT-29 和 MKN-45 细胞系显示出有效的活性和高选择性。此外,进一步检查了化合物 21b、21c 和 21i 的 c-Met 激酶活性,并表现出强大的功效,IC50 值在个位数纳摩尔范围内,与阳性对照 foretinib 相当。最有希望的化合物 21c 显示出优异的细胞抑制活性,对所有测试细胞系的 IC50 值为 0.01 至 0.53 µM,因此比 foretinib 的活性高 1.7-2.2 倍。
