A series of 6,7-disubstituted-4-phenoxyquinoline derivatives bearing the 1,8-naphthyridin-2-one moiety were designed, synthesized and evaluated for their biological activities. The target compounds exhibited moderate to high antiproliferative activity against three cancer cell lines (A549, HepG2 and MCF-7) and several compounds (25, 27, 33, 37, 41, 43, 49 and 53) were evaluated for the activity against
设计,合成和评估了一系列带有1,8-萘啶-2-酮部分的6,7-二取代-4-苯氧基喹啉衍生物。目标化合物表现出中度至对三名癌细胞系高的抗增殖活性(A549,HepG2和MCF-7)和几种化合物(25,27,33,37,41,43,49和53),用于针对c的活性进行了评估-Met激酶。最有前途的化合物33(IC 50 c-Met = 2.36 nM)对具有IC 50的A549,HepG2和MCF-7细胞系表现出优异的活性值分别为0.23μM,0.42μM和0.21μM,是阳性对照的1.5–2.1倍。此外,评估了化合物33对Flt3,PDGFR-α,PDGFR-β,c-Kit,Flt4,ALK和EGFR激酶的活性。结构活性关系研究表明, C部分4位的单EWG(例如R 2 = F)是提高抗肿瘤活性的关键因素。另外,对化合物33的进一步研究主要包括浓度依赖性,细胞凋亡(ac啶橙染色),细胞凋亡结果分析和分子对接。
