A variety of 5-alkyl-, 5-amino- and 5-hydroxy-6,8-diaryl-1,7-naphthyridines have been efficiently prepared by the treatment of suitable 2-azaallyl anions with diversely functionalized 2-halogenopyridines.

CAMKK2 is a serine/threonine kinase and an activator of AMPK whose dysregulation is linked with multiple diseases. Unfortunately, STO-609, the tool inhibitor commonly used to probe CAMKK2 signaling, has limitations. To identify promising scaffolds as starting points for the development of high-quality CAMKK2 chemical probes, we utilized a hinge-binding scaffold hopping strategy to design new CAMKK2 inhibitors. Starting from the potent but promiscuous disubstituted 7-azaindole GSK650934, a total of 32 compounds, composed of single-ring, 5,6-, and 6,6-fused heteroaromatic cores, were synthesized. The compound set was specifically designed to probe interactions with the kinase hinge-binding residues. Compared to GSK650394 and STO-609, 13 compounds displayed similar or better CAMKK2 inhibitory potency in vitro, while compounds 13g and 45 had improved selectivity for CAMKK2 across the kinome. Our systematic survey of hinge-binding chemotypes identified several potent and selective inhibitors of CAMKK2 to serve as starting points for medicinal chemistry programs.

JmjC domain-containing protein 6 (JMJD6) has been thought as a potential target for various diseases particularly cancer. However, few selective JMJD6 inhibitors have been reported. In this investigation, molecular docking and biological activity evaluation were performed to retrieve new JMJD6 inhibitors, which led to the identification of a hit compound, J2. Further structural optimization and structure–activity relationship (SAR) analysis towards J2 were carried out, which gave a new potent JMJD6 inhibitor, 7p. This compound showed an IC50 value of 0.681 μM against JMJD6, but displayed no activity against other tested JmjC domain-containing protein family members, indicating good selectivity (>100 fold). Collectively, this investigation offers a selective JMJD6 inhibitor, which could be taken as a lead compound for subsequent drug discovery targeting JMJD6.
