Abstract: Deregulation of protein synthesis is a common event in cancer. As MAPK-interacting kinases (Mnks) play critical roles in regulation of protein synthesis, they have emerged as novel anti-cancer targets. Mnks phosphorylate eukaryotic initiation factor 4E (eIF4E) and promote eIF4E-mediated oncogenic activity. Given that the kinase activity of Mnks is essential for oncogenesis but is dispensable for normal development, the discovery of potent and 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 of highly potent Mnk2 inhibitors that could be potential leads for the treatment of acute myeloid leukemia.
