Pyrrolopyrimidine, a novel scaffold, allows to adjust interactions within the S3 subsite of cathepsin K. The core intermediate 10 facilitated the P3 optimization and identified highly potent and selective cathepsin K inhibitors 11-20.

With the emergence of multidrug-resistant strains of Mycobacterium tuberculosis (MDR-TB) and extensive drug-resistant strains (XDR-TB), there is an urgent need to develop novel drugs for the treatment of tuberculosis. Here, we designed and synthesized a series of 5-methylpyrimidopyridone analogues as potential antitubercular agents. The most potent compound 6q exhibited a MIC value of 4 μM in vitro against Mycobacterium tuberculosis. The antitubercular activities of the synthesized compounds were impacted by the amantadine and 2-chlorophenyl groups, and were enhanced by the presence of 3-methyl(4-dimethylamino)piperidinylphenyl. Molecular modeling and binding studies suggest that PknB is the potential molecular target of 5-methylpyrimidopyridone compounds. This study provides insights for the future development of new antimycobacterial agents with novel mechanisms of action.

We describe the structural optimization of a lead compound 1 that exhibits dual inhibitory activities against FLT3 and CDK4. A series of pyrido[4′,3′:4,5]pyrrolo[2,3-d]pyrimidine derivatives was synthesized, and SAR analysis, using cell-based assays, led to the discovery of 28 (AMG 925), a potent and orally bioavailable dual inhibitor of CDK4 and FLT3, including many FLT3 mutants reported to date. Compound 28 inhibits the proliferation of a panel of human tumor cell lines including Colo205 (Rb +) and U937 (FLT3WT) and induced cell death in MOLM13 (FLT3ITD) and even in MOLM13 (FLT3ITD, D835Y), which exhibits resistance to a number of FLT3 inhibitors currently under clinical development. At well-tolerated doses, compound 28 leads to significant growth inhibition of MOLM13 xenografts in nude mice, and the activity correlates with inhibition of STAT5 and Rb phosphorylation.

Mps1, also known as TTK, is a mitotic checkpoint protein kinase that has become a promising new target of cancer research. In an effort to improve the lead-likeness of our recent Mps1 purine lead compounds, a scaffold hopping exercise has been undertaken.
