A series of hybrid anaplastic lymphoma kinase (ALK) inhibitors (Y1∼Y30) were designed by assembling aminoindazole of Entrectinib onto 2-position of 2,4-diarylaminopyrimidine (DAAP) fragment to serve as ATP dual-mimic agents. Under structure-based optimization, all conjugates were detected moderate to excellent cytotoxicity potency, among which the pyrrolidine analog Y28 exerted optimal antiproliferative
通过将恩曲替尼的氨基吲唑组装到 2,4-二芳基氨基嘧啶 (DAAP) 片段的 2 位上,作为 ATP 双重模拟剂,设计了一系列混合间变性淋巴瘤激酶 (ALK) 抑制剂 ( Y1 ∼ Y30 )。在基于结构的优化下,检测到所有偶联物均具有中等至优异的细胞毒性效力,其中吡咯烷类似物Y28对 ALK 成瘾细胞系发挥最佳抗增殖作用,IC 50值低于 20 nM。作为一种高效的 ALK 抑制剂(ALK WT,IC 50 = 1.6 nM),Y28还能够抑制 ALK 抗性突变,包括 ALK L1196M (0.71 nM) 和 ALKG1202R (1.3 纳米)。有趣的是,Y28以剂量依赖性方式有效抑制集落形成并抑制 H2228 细胞的细胞迁移。此外,流式细胞仪分析表明,Y28可以诱导细胞凋亡,使细胞周期停滞在G2期。值得注意的是,在 H2228 异种移植模型中,口服 50 mg/kg 的Y28可使肿瘤消退,肿瘤生长抑制值为
