Abstract

Protein kinases are important drug targets, especially in the area of oncology. This paper reports the synthesis and biological evaluation of new 7-azaindole derivatives bearing benzocycloalkanone motifs as potential protein kinase inhibitors. Four compounds 8g, 8h, 8i, and 8l were discovered to inhibit cyclin-dependent kinase 9 (CDK9/CyclinT) and/or Haspin Kinase in the micromolar to nanomolar range. 8l was identified as the most potent Haspin inhibitor (IC50 = 14 nM), while 8g and 8h acted as dual inhibitors of CDK9/CyclinT and Haspin. These novel compounds constitute a promising starting point for the discovery of dual protein kinase inhibitors that have potential to be developed as Anticancer agents, since both CDK9/CyclinT and Haspin are considered to be drug targets in oncology.
