The 7-azaindole scaffold attracts attention due to its value in the design of inhibitors of diseases related protein kinases. However, this scaffold has not been evaluated against Haploid germ cell-specific nuclear protein kinase (Haspin). Herein, we report the synthesis of a select set of 7-azaindole derivatives and their evaluation against Haspin. The compounds were also evaluated against CDK9/Cyclin T kinase. The synthesis of 7-azaindole derivatives was achieved through Suzuki coupling using appropriate halogenated 7-azaindole and boronic acids. Seven of the screened compounds exhibited activity as CDK9/Cyclin T and/or Haspin inhibitors in a nanomolar to low micromolar range. The most promising dual inhibiting compound 18c, exhibited an inhibitory potential of 0.206 μM against CDK9/Cyclin T and 0.118 μM against Haspin. The dual inhibition of CDK9/Cyclin T and Haspin could afford a potentially potent antimitotic agent of value in further anticancer studies.

The use of covalent irreversible binding inhibitors is an established concept for drug development. Usually, the discovery of new irreversible kinase inhibitors occurs serendipitously, showing that efficient rational approaches for the rapid discovery of new drugs are needed. Herein, we report a virtual screening strategy that led to the discovery of irreversible inhibitors of FMS-like tyrosine kinase 3 (FLT3) involved in the pathogenesis of acute myeloid leukemia. A virtual screening library was designed to target the highly conserved Cys828 residue preceding the DFG motif by modification of reported reversible inhibitors with chemically reactive groups. Prospective covalent docking allowed the identification of two lead series, resulting in a massive increase in inhibition of kinase activity and cell viability by irreversible inhibitors compared to the corresponding reversible scaffolds. Lead compound 4b (BSc5371) displays superior cytotoxicity in FLT3-dependent cell lines to compounds in recent clinical trials and overcomes drug-resistant mutations.

Potent inhibitors of RIP1 kinase from three distinct series, 1-aminoisoquinolines, pyrrolo[2,3-b]pyridines, and furo[2,3-d]pyrimidines, all of the type II class recognizing a DLG-out inactive conformation, were identified from screening of our in-house ki
