A series of 2-substituted-4-phenoxypyridine derivatives were designed, synthesized, and evaluated for their antiproliferative activity against 4 cancer cell lines (A549, HT-29, H460, and U87MG) in vitro. Most compounds showed moderate to excellent potency. Nine tyrosine kinases (c-Met, Flt-3, ALK, VEGFR-2, VEGFR-3, PDGFR-α, PDGFR-β, c-Kit, and EGFR) were used to evaluate the inhibitory activities with
设计,合成了一系列2-取代的4-苯氧基吡啶衍生物,并在体外评估了它们对4种癌细胞系(A549,HT-29,H460和U87MG)的抗增殖活性。大多数化合物显示出中等至极好的效价。九种酪氨酸激酶(c-Met,Flt-3,ALK,VEGFR-2,VEGFR-3,PDGFR-α,PDGFR-β,c-Kit和EGFR)用于评估最有前途的类似物39的抑制活性。,显示Flt-3 / c-Met IC 50值为2.18 / 2.61 nM。构效关系研究表明,n-Pr作为R 1基团表现出更高的偏好性,而苯环上更强的单EWG(如R 2 = 4-F)则受益于其效价。
