General description

A cell-permeable indoloquinazolinone compound that acts as a potent, selective, and reversible CK2 inhibitor (IC50 = 390 nM with 100 M ATP) in an ATP- and GTP-competitive manner (Ki = 0.17 and 0.21 M, respectively). IQA exhibits much reduced activity against PI 3-Kα/β/γ (No inhibition at 20 M) and 48 commonly studied protein kinases (IC50 ≥10 M with 100 M ATP) and is more selective than TBB (Cat. Nos. 218697 and 218708) with respect to DYRK1a (IC50 = 8 and <1 M, respectively, with 100 M ATP).
