Excessive phosphorylation of eukaryotic translation initiation factor 4E (eIF4E) plays a major role in the dysregulation of mRNA translation and the activation of tumor cell signaling. eIF4E is exclusively phosphorylated by mitogen-activated protein kinase interacting kinases 1 and 2 (MNK1/2) on Ser209. So, MNK1/2 inhibitors could decrease the level of p-eIF4E and regulate tumor-associated signaling pathways. A series of pyridone–aminal derivatives were synthesized and evaluated as MNK1/2 inhibitors. Several compounds exhibited great inhibitory activity against MNK1/2 and selected compounds showed moderate to excellent anti-proliferative potency against hematologic cancer cell lines. In particular, compound 42i (MNK1 IC50 = 7.0 nM; MNK2 IC50 = 6.1 nM) proved to be the most potent compound against TMD-8 cell line with IC50 value of 0.91 μM. Furthermore, 42i could block the phosphorylation level of eIF4E in CT-26 cell line, and 42i inhibited the tumor growth of CT-26 allograft model significantly. These results indicated that compound 42i was a promising MNK1/2 inhibitor for the potent treatment of colon cancer.

A set of forty-seven Akt1 inhibitors was used for the development of molecular docking based QSAR model by using nonlinear regression. The integration of docking scores, key interaction profiles and molecular descriptors remarkably improved the accuracy of the QSAR models, providing reasonable statistical parameters (Rtrain2 = 0.948, R test2 = 0.907 and Qcv2 = 0.794). The established MD-SVR model based structural modification of new 4-amino-pyrimidine derivatives was further performed, and six compounds 56a,b and 60a-d with good prediction activities were synthesized and biologically evaluated. All of these compounds exhibited promising Akt1 inhibitory and antiproliferative activities, suggesting the reliability and good application value of the established MD-SVR model in the development of Akt1 inhibitors.
