cellular and enzymatic assays validated 34c (WY-135) as a promising ALK (IC50 = 1.4 nM) and ROS1 (IC50 = 1.1 nM) dual inhibitor superior to crizotinib and ceritinib. 34c showed significantly inhibitory activities on ALK-dependent cell lines KARPAS299 (IC50 = 21 nM) and H2228 (IC50 = 95 nM) as well as ROS1-positive cell line HCC78 (IC50 = 40 nM). In particular, 34c was potent against a variety of frequently
旨在探索新型的间变性淋巴瘤激酶(ALK)和原癌基因酪氨酸蛋白激酶ROS(ROS1)双重抑制剂,以克服耐克唑替尼的突变体,两个系列的带有噻唑或1,2的2,4-二芳基氨基嘧啶(DAAP)类似物, 3-三唑基部分被设计和基于ceritinib与ALK共晶体结构合成WT(PDB 4MKC)以及ceritinib与ALK结合模型G1202R。细胞和酶促测定证实34c(WY-135)是 优于crizotinib和ceritinib的有前景的ALK(IC 50 = 1.4 nM)和ROS1(IC 50 = 1.1 nM)双重抑制剂。34c对ALK依赖的细胞系KARPAS299(IC 50 = 21 nM)和H2228(IC 50 = 95 nM)以及ROS1阳性细胞系HCC78(IC 50 = 40 nM)表现出显着的抑制活性。特别是,34c对多种经常观察到的耐克唑替尼耐药的突变体有效,特别是被
