selective pharmacological Mnk inhibitors provides pharmacological target validation and offers a new strategy for cancer treatment. Herein, comprehensive in silico screening approaches were deployed, and three thieno[2,3-d]pyrimidine and pyrazolo[3,4-d]pyrimidine derivatives were identified as hit compounds. Further chemical modification of thieno[2,3-d]pyrimidine derivative 3 has given rise to a series
蛋白质合成失调是癌症中的常见事件。由于与MAPK相互作用的激酶(Mnks)在调节蛋白质合成中起关键作用,因此它们已成为新型的抗癌靶标。Mnks磷酸化真核起始因子4E(eIF4E),并促进eIF4E介导的致癌活性。鉴于Mnks的激酶活性对于肿瘤发生是必不可少的,但对于正常发育却是必不可少的,因此,有效且选择性的Mnk药理抑制剂的发现提供了药理学靶点验证,并为癌症治疗提供了新的策略。在这里,部署了全面的计算机筛选方法,并确定了三种噻吩并[2,3-d]嘧啶和吡唑并[3,4-d]嘧啶衍生物为命中化合物。Thieno的进一步化学修饰[2,
