so far hampered pharmacological target validation and clinical drug development. Herein, we report, for the first time, the discovery of a series of 5‐(2‐(phenylamino)pyrimidin‐4‐yl)thiazole‐2(3H)‐one derivatives as Mnk inhibitors. Several derivatives demonstrate very potent Mnk2 inhibitory activity. The most active and selective compounds were tested against a panel of cancer cell lines, and the results
人类促分裂原激活蛋白激酶(MAPK)相互作用激酶(Mnks)对eIF4E的磷酸化对于人类肿瘤的发生和发展至关重要。靶向Mnks可能提供一种新颖的抗癌治疗策略。然而,迄今为止缺乏选择性的Mnk抑制剂已经阻碍了药理学靶标的验证和临床药物的开发。在此,我们首次报告了一系列5-(2-(苯基氨基)嘧啶-4-基)噻唑-2(3 H一种衍生物作为Mnk抑制剂。几种衍生物表现出非常强的Mnk2抑制活性。针对一组癌细胞系测试了最具活性和选择性的化合物,结果证实了这些Mnk抑制剂的细胞类型特异性作用。详细的细胞机制研究表明,Mnk抑制剂能够降低抗凋亡蛋白Mcl-1的表达水平,并能促进MV4-11急性髓性白血病细胞的凋亡。
