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.

Harboring MYD88 L265P mutation triggers tumors growth through the activation of NF-κB by interleukin-1 receptor associated kinase 4 (IRAK4) in diffuse large B-cell lymphoma (DLBCL), highlighting IRAK4 as a therapeutic target for tumors driven by aberrant MYD88 signaling. Herein, we report the design, synthesis, and structure?activity relationships of imidazo[1,2-b]pyridazines as potent IRAK4 inhibitors. The representative compound 5 exhibited excellent IRAK4 potency (IRAK4 IC50 = 1.3 nM) and favorable kinase selectivity profile. It demonstrated cellular selectivity for activated B cell–like (ABC) subtype DLBCL with MYD88 L265P mutation in cytotoxicity assay. The kinase inhibitory efficiency of compound 5 was further validated by Western blot analysis of phosphorylation of IRAK4 and downstream signaling in OCI-LY10 and TMD8 cells. Besides, combination of compound 5 and BTK inhibitor ibrutinib synergistically reduced the viability of TMD8 cells. These results indicated that compound 5 could be a promising IRAK4 inhibitor for the treatment of mutant MYD88 DLBCL.
