Novel quinoline derivatives bearing acyclic semicarbazones were prepared and their chemical structures as well as the relative stereochemistry were confirmed. All the synthesized compounds were evaluated for their c‐Met kinase inhibitory activity and their cytotoxicity against the cell lines HT‐29, MKN‐45, and MDA‐MB‐231 in vitro. Several potent compounds were further evaluated against A549 cells.
制备了带有无环缩氨基脲的新型喹啉衍生物,并确定了它们的化学结构和相对立体化学。在体外评估了所有合成化合物的 c-Met 激酶抑制活性和对细胞系 HT-29、MKN-45 和 MDA-MB-231 的细胞毒性。针对 A549 细胞进一步评估了几种有效化合物。大多数化合物显示出中等至极好的活性,结构-活性关系研究确定了最有希望的化合物 35 作为选择性 c-Met 激酶抑制剂 (IC50 = 4.3 nM)。与 foretinib 相比,化合物 35 在体外对 HT-29 和 A549 细胞的细胞毒性分别增加了 3.5 倍和 18.8 倍。
