  • ATP/GTP-competitive cell permeable casein kinase II (CK2) inhibitor (IC50=0.9µM for rat liver. Less potently inhibits CCK2/cyclin A, GSK3β and phosphorylase kinase (IC50=15.6, 11.2 and 8.7µM, respectively). Binds to the Val66 residue of CK2 and inhibits the binding of ATP/GTP.
  • Moderate DYRK1A inhibitor (IC50=4.4µM).
  • Induces caspase-dependent apoptosis and degrades hematopoietic lineage cell-specific protein 1 (HS1) in Jurkat cells.
