A series of 6,7-disubstituted-4-phenoxyquinoline derivatives bearing the 2-oxo-4-chloro-1,2-dihydroquinoline-3-carboxamide moiety were synthesized, and evaluated for their antiproliferative activity against 5 cancer cell lines (H460, HT-29, MKN-45, A549, and U87MG). Most compounds showed moderate to excellent potency, and compared to foretinib, the most promising analog 42 (c-Met/Flt-3 IC50 = 1.21/2
合成了一系列带有2-oxo-4-chloro-1,2,dihydroquinoline-3-carboxamide部分的6,7-di取代-4-phenoxyquinoline衍生物,并评估了它们对5种癌细胞系(H460, HT-29,MKN-45,A549和U87MG)。大多数化合物显示出中等至出色的效力,并且与foretinib相比,最有前途的类似物42(c-Met / Flt-3 IC 50 = 1.21 / 2.15 nM)在体外对H460细胞系的活性提高了6.1倍。在体外评估了化合物42的酶促测定(c-Met,VEGFR-2,Flt-3,PDGFR-β,c-Kit和EGFR)。对接分析表明,化合物42可以与c-Met形成三个氢键 结构与活性之间的关系研究表明,在苯环的4位上,水溶性更强的环状叔胺和吸电子基团有助于抗肿瘤活性。
