The new halogenated 1H-triazolo[4,5-b]pyridines and 1H-imidazo[4,5-b]pyridines were synthesised as analogues of known CK2 inhibitors: 4,5,6,7-tetrabromo-1H-benzotriazole (TBBt) and 4,5,6,7-tetrabromo-1H-benzimidazole (TBBi). Their influence on the activity of recombinant human CK2α, CK2α’ and PIM1 kinases was determined. The most active inhibitors were di- and trihalogenated 1H-triazolo[4,5-b]pyridines (4a, 5a and 10a) with IC50 values 2.56, 3.82 and 3.26 μM respectively for CK2α. Furthermore, effect on viability of cancer cell lines MCF-7 (human breast adenocarcinoma) and CCRF-CEM (T lymphoblast leukemia) of all final compounds was evaluated. Finally, three crystal structures of complexes of CK2α1-335 with inhibitors 4a, 5a and 10a were obtained. In addition, new protocol was used to obtain high-resolution crystal structures of CK2α’Cys336Ser in complex with four inhibitors (4a, 5a, 5b, 10a).

Focal adhesion kinase (FAK) is considered as an attractive target for oncology, and small-molecule inhibitors are reported to be in clinical testing. In a surface plasmon resonance (SPR)-mediated fragment screening campaign, we discovered bicyclic scaffolds like 1H-pyrazolo[3,4-d]pyrimidines binding to the hinge region of FAK. By an accelerated knowledge-based fragment growing approach, essential pharmacophores were added. The establishment of highly substituted unprecedented 1H-pyrrolo[2,3-b]pyridine derivatizations provided compounds with submicromolar cellular FAK inhibition potential. The combination of substituents on the bicyclic templates and the nature of the core structure itself have a significant impact on the compounds FAK selectivity. Structural analysis revealed that the appropriately substituted pyrrolo[2,3-b]pyridine induced a rare helical DFG-loop conformation. The discovered synthetic route to introduce three different substituents independently paves the way for versatile applications of the 7-azaindole core.
