Six series of novel 4-(2-fluorophenoxy)-3,3′-bipyridine derivatives conjugated with aza-aryl formamide/amine scaffords were designed and synthesized through a structure-based molecular hybridization approach. The target compounds were evaluated for c-Met kinase inhibitory activities and cytotoxicity against four cancer cell lines (HT-29, A549, MKN-45 and MDA-MB-231) in vitro. Most compounds exhibited
通过基于结构的分子杂交方法,设计合成了六种新颖的与氮杂芳基甲酰胺/胺骨架共轭的4-(2-氟苯氧基)-3,3'-联吡啶衍生物。评估了目标化合物在体外对四种癌细胞系(HT-29,A549,MKN-45和MDA-MB-231)的c-Met激酶抑制活性和细胞毒性。大多数化合物均表现出中等至出色的效力,最有前途的候选蛋白26c(c-Met激酶IC 50 = 8.2 nM)在体外对c-Met上瘾的MKN-45细胞系的细胞毒性增加了4.7倍(IC 50 = 3 nM),优于Foretinib(IC 50 = 23 nM)。初步的结构-活性关系表明,1 H-苯并[e] [1,3,4]噻二嗪-3-羧酰胺-4,4-二氧化物部分作为连接基有助于抗肿瘤作用。
