在继续我们先前的研究中,设计,合成了带有哒嗪酮部分的八个系列的吡咯并[2,3- b ]吡啶和吡咯并[2,3- d ]嘧啶衍生物,并评估了其对四种癌细胞的体外抗肿瘤活性。线(A549,HepG2,MCF-7和PC-3)。评估了一些选定的化合物(22f,22g,26c和26e)的抗c-Met激酶活性,并根据激酶抑制活性的结果,进一步评估了化合物22g的其他四种酪氨酸激酶(Flt-3,VEGFR -2,c-Kit和EGFR)来测试基于酶的选择性。最有希望的化合物,22克与Foretinib相比,其针对A549,HepG2,MCF-7和PC-3细胞系表现出优异的活性,IC 50值分别为2.19±0.45μM,1.32±0.26μM,6.27±1.04μM和4.63±0.83μM。结构-活性关系(SARs)和对接研究表明,带有4-氧代-哒嗪酮部分的吡咯并[2,3- b ]吡啶衍生物优于带有6-氧代-吡咯并[2
epithelial transition factor (MET) has been implicated in several human cancers and is an attractive target for small molecule drug discovery. Herein, a series of 6,7-disubstituted-4-phenoxyquinoline derivativesbearing pyridazinone derivatives were designed, synthesized and evaluated for their enzymatic inhibitory activity against c-Met kinase and cellular potency against A549, HepG2, and MCF-7 cell lines

that simultaneously inhibits multiple targets has been widely used in cancer treatment to overcome complicated dose design and anti-cancer resistance. Inspired by the synergistic effects between c-Met and HDAC in tumor development, a novel series of c-Met/HDAC bifunctional inhibitors was designed and synthesized by merging the pharmacophores of HDAC inhibitor into a c-Met inhibitor. All the target compounds
We disclosed the preparation and biological evaluation of a series of [1,2,4]triazolo[4,3-a]pyrazine derivatives bearing 4-oxo-pyridazinone moieties, which demonstrated potent inhibition of c-Met kinase, culminating in the discovery of 22i.
