Second-generation CK2 alpha inhibitors targeting the alpha D pocket.
Chem Sci, 9:3041-3049, 2018

PubMed Abstract: CK2 is a critical cell cycle regulator that also promotes various anti-apoptotic mechanisms. Development of ATP-non-competitive inhibitors of CK2 is a very attractive strategy considering that the ATP binding site is highly conserved among other kinases. We have previously utilised a pocket outside the active site to develop a novel CK2 inhibitor, . Whilst bound to this new pocket it was also interacting with the ATP site: herein, we describe an example of a CK2α inhibitor that binds completely outside the active site. This second generation αD-site binding inhibitor, compound (IC = 7 μM, GI = 10.0 ± 3.6 μM), has numerous advantages over the previously reported , including a reduction in the number of rotatable bonds, the absence of amide groups susceptible to the action of proteases and improved cellular permeability. Unlike with , there was no need to facilitate cellular uptake by making a prodrug. Moreover, displayed no drop off between its ability to inhibit the kinase (IC) and the ability to inhibit cell proliferation (GI).
