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.

The invention relates to substituted pyrimidine compounds and an application thereof. The substituted pyrimidine compounds are compounds shown in a formula I (the specific structure is shown in the specification or claims), stereoisomers of the compounds or pharmaceutically acceptable salts of the compounds. An in-vitro activity test proves that the substituted pyrimidine compounds have cholinesterase inhibiting activity, metal ion chelation, inhibition of generation of metal ion induced free radicals, inhibition of metal ion induced Abeta aggregation and the like. Therefore, the substituted pyrimidine compounds are expected to be used for preparing Alzheimer's disease treating and/or preventing drugs.
