ABSTRACT
Acylaminoindazole-based inhibitors of CDKL2 were identified via analyses of cell-free binding and selectivity data. Compound 9 was selected as a CDKL2 chemical probe based on its potent inhibition of CDKL2 enzymatic activity, engagement of CDKL2 in cells, and excellent kinome-wide selectivity, especially when used in cells. Compound 16 was designed as a negative control to be used alongside compound 9 in experiments to interrogate CDKL2-mediated biology. A solved cocrystal structure of compound 9 bound to CDKL2 highlighted key interactions it makes within its ATP-binding site. Inhibition of downstream phosphorylation of EB2, a CDKL2 substrate, in rat primary neurons provided evidence that engagement of CDKL2 by compound 9 in cells resulted in inhibition of its activity. When used at relevant concentrations, compound 9 does not impact the viability of rat primary neurons or certain breast cancer cells nor elicit consistent changes in the expression of proteins involved in epithelial-mesenchymal transition.
