A series of pyrrolo[2,3-b]pyridine derivatives bearing 4-oxoquinoline moiety were designed, synthesized and evaluated for the anti-proliferative on three cancer cell lines (A549, HepG2 and MCF-7) in vitro. Most of the compounds showed moderate to high potency. Some excellent compounds were tested for the inhibitory activity of c-Met kinase. Compound 34 (c-Met IC50 = 17 nM) was investigated the selectivity
设计,合成了一系列带有4-氧代喹啉部分的吡咯并[2,3-b]吡啶衍生物,并评估了它们在三种癌细胞系(A549,HepG2和MCF-7)上的抗增殖作用。大多数化合物显示出中等至高的效力。测试了一些优秀的化合物对c-Met激酶的抑制活性。研究了化合物34(c-Met IC50 = 17 nM)对Flt-3,c-Kit,VEGFR-2,ALK,PDGFR-β和RON的选择性。结构-活性关系研究表明,R,R1和R2上的氢,氟原子和单电子吸取基团(单EWG,例如R2 = F)有利于靶标的抗增殖活性化合物。此外,我们还通过分子对接进一步研究了化合物34与c-Met激酶之间的结合方式。
