A series of 6,7-disubstituted-4-phenoxyquinoline derivatives bearing 4-oxo-3,4-dihydrophthalazine-1-carboxamide moieties were designed, synthesized and evaluated for their c-Met kinase inhibition and cytotoxicity against H460, MKN-45, HT-29 and MDA-MB-231 cancer cell lines in vitro. Most compounds displayed good to excellent potency against four tested cancer cell lines as compared with foretinib.
设计,合成并评估了一系列带有4-oxo-3,4-dihydrophthalazine-1-carboxamide部分的6,7-dipropyl-4-phenoxyquinoline衍生物,并评估了它们对c-Met激酶的抑制作用和对H460,MKN-45,体外HT-29和MDA-MB-231癌细胞系。与福瑞替尼相比,大多数化合物对四种测试的癌细胞系表现出良好至极佳的效力。SAR分析表明,在苯环的4位上具有卤素基团,尤其是氟基的化合物(B部分)比具有硝基或甲氧基的化合物更有效。在这项研究中, 鉴定出了有前途的化合物33(c-Met IC 50 = 1.63 nM),该化合物显示了用IC 50最有效的抗肿瘤活性 分别针对H460,MKN-45,HT-29和MDA-MB-231细胞系的0.055μM,0.071μM,0.13μM和0.43μM值。
