Application

Quinalizarin has been used:
  • as a casein kinase II (CKII) inhibitor to study its effect on CKII-mediated phosphorylation of importin α on subcellular scaling in sperm chromosomes and egg extract
  • as a CKII inhibitor to study its ability to block parasite multiplication in a [3H]-hypoxanthine incorporation assay
  • to study its effect on colorectal cancer (CRC) cell cycle arrest, cell apoptosis, and reactive oxygen species (ROS) generation in SW480 and HCT-116 cell lines

Biochem/physiol Actions

Quinalizarin is a potent (IC50 = 110 nM), ATP-competitive, and highly selective (IC50 >1μM against CK1 and 72 other kinases) casein Kinase II (CK2) inhibitor.
Studies show that quinalizarin can prevent the in vitro activity of recombinant Plasmodium falciparum casein kinase 2α (PfCK2α) catalytic subunit with an IC50 of 2μM.

It has been proposed that dual inhibitors of protein kinases CK2 and PIM-1 are tools particularly valuable to induce apoptosis of cancer cells, a property, however, implying cell permeability, which is lacking in the case of selective CK2/PIM-1 inhibitors developed

Protein kinase CK2 is a pleiotropic tetrameric enzyme, regulating numerous biological processes from cell proliferation to stress response. This study demonstrates for the first time that CK2 is involved in the regulation of metal uptake and toxicity in neuronal cells.
