In order to explore novel ALK and ROS1 dual inhibitors capable of overcoming crizotinib-resistant mutants, two series of 2,4-diarylaminopyrimidine derivatives were designed, synthesized and evaluated for their in vitro cytotoxic activity. In this work, we retained the 2,4-diarylaminopyrimidine scaffold and derivatize the DAAP scaffold with sulfonyl and acrylamide moieties to extend the structure-activity
为了探索能够克服耐克唑替尼的突变体的新型ALK和ROS1双重抑制剂,设计,合成并评估了两个系列的2,4-二芳基氨基嘧啶衍生物的体外细胞毒性活性。在这项工作中,我们保留了2,4-二芳基氨基嘧啶骨架,并用磺酰基和丙烯酰胺基团衍生了DAAP骨架,以扩展结构-活性关系(SAR)研究。令我们高兴的是,某些化合物在MTT分析中显示出优异的抑制活性,其纳摩尔浓度达到两位数。进一步选择了四种化合物进行酶分析,结果鉴定出了有效的ALK和ROS1双重抑制剂X-17,针对ALK,ALK的IC 50值为3.7nM,2.3nM,8.9nM和1.9nM。分别为L1196M,ALK G1202R和ROS1。最终,在X-17上进行的分子对接研究清楚地揭示了与ALK的合理和最佳结合相互作用。
