A series of pyrrolo[2,3-b]pyridine derivatives bearing the 1,8-naphthyridin-2-one moiety were synthesized, and evaluated for their antiproliferative activity against four cancer cell lines (HT-29, A549, H460, and U87MG) and six tyrosine kinases (c-Met, Flt-3, PDGFR-β, VEGFR-2, EGFR, and c-Kit) inhibitory activities in vitro. Most compounds showed moderate to excellent potency, with the most promising
合成了一系列带有1,8-萘啶-2-酮部分的吡咯并[2,3- b ]吡啶衍生物,并评估了它们对四种癌细胞系(HT-29,A549,H460和U87MG)的抗增殖活性)和六种酪氨酸激酶(c-Met,Flt-3,PDGFR-β,VEGFR-2,EGFR和c-Kit)的体外抑制活性。大多数化合物显示出中等至极好的效价,最有前途的类似物32的Flt-3 / c-Met IC 50值为1.16 / 1.92 nM。构效关系研究表明,氢原子作为R 1基团具有较强的效力,苯环上的单电子吸电子基团(mono-EWGs)(如R 3 = 4-F)对抗增殖活性表现出更高的偏爱。
