A series of novel 4‐phenoxyquinoline derivatives containing the benzo[d]thiazole‐2‐yl urea moiety were synthesized and evaluated for their cytotoxicity against the HT‐29, MKN‐45, and H460 cell lines. The structures of the target compounds were confirmed by 1H NMR and MS spectra. Most of them showed moderate to excellent potency against the three tested cell lines. Especially, compound 23 was identified
合成了一系列含有苯并[d]噻唑-2-基脲部分的新型4-苯氧基喹啉衍生物,并评估了它们对HT-29、MKN-45和H460细胞系的细胞毒性。目标化合物的结构经1H NMR和MS谱确证。它们中的大多数对三种测试细胞系显示出中等至极好的效力。特别是,化合物 23 被鉴定为一种有前途的药物(c-Met IC50 = 17.6 nM),显示出最有效的抗癌活性,对 HT-29、MKN-45 和 H460 细胞系的 IC50 值为 0.18、0.06 和 0.01 µM , 分别。23 与 c-Met 激酶模型 3LQ8 的对接结果显示了配体和靶蛋白之间的特异性结合模式。
