Anwendung

DMAT has been used as a casein kinase 2 (CK2) inhibitor:
  • to study its effects on parasite multiplication in a [3H]-hypoxanthine incorporation assay
  • to study its effects on the intracellular response in prostate cancer cells
  • to study its effects on cell division cycle 25C (cdc25C) phosphatase levels in prostate cancer cells

Biochem./physiol. Wirkung

Casein kinase II inhibitor II (Ck2 Inhibitor II) is a high affinity ATP-competitive inhibitor of casein kinase II. Ck2 Inhibitor II inhibits CK2 in rat liver with 1,300-fold greater selectivity for CK2 than for CK1 (IC50 = 140 nM and >200 μM respectively). Ki = 40 nM; In Jurkat human T-cell leukemia cells, Ck2 Inhibitor II does not display side effects on mitochondria polarization at concentrations up to 10 μM; Ck2 Inhibitor II is useful for in vivo studies due to cell permeability and high efficacy in cultured cells and has implications in research and treatment of neoplasia and infective diseases, in which CK2 plays a role and is highly active constitutively.
DMAT is an ATP-competitive (Ki = 40 nM) casein kinase 2 (CK2) inhibitor (IC50 = 140 nM; rat liver CK2, [ATP] = 20 nM) with greatly improved potency and selectivity than its structure analog TBB. With the exception of DYRK1a (IC50 = 120 nM), DMAT is reported to exhibit no CK1 inhibitiory potency up to 200 μM (50% inhibition by 29 μM TBB) and little or no activity against a panel of 32 other protein kinases, nor PI3K α and γ. When tested in Jurkat cultures, DMAT is shown to be a superior apoptosis inducer than TBB (DC50 = 2.7 μM/DMAT vs. 17 μM/TBB).

Benzimidazole derivatives of 5,6-dichlorobenzimidazole 1-β-D-ribofuranoside (DRB) comprise the important class of protein kinase CK2 inhibitors. Depending on the structure, benzimidazoles inhibit CK2 with different selectivity and potency. Besides CK2, the compounds can inhibit, with similar activity, other classical eukaryotic protein

Protein kinase CK2 is implicated in the regulation of the cell cycle. In addition to a variety of functions, CK2 has anti-apoptotic properties. So far the role of CK2 linking both pathways in the cell is not clear. Some years

Casein kinase 2 (CK2) is a ubiquitous, essential, and highly pleiotropic protein kinase whose abnormally high constitutive activity is suspected to underlie its pathogenic potential in neoplasia and infective diseases. Thus, CK2 inhibitors designed to dissect the signaling pathways affected

Protein kinase CK2 is a highly pleiotropic enzyme whose high constitutive activity is suspected to be instrumental to the enhancement of the tumour phenotype and to the propagation of infectious diseases. Here we describe a novel compound, 2-dimethylamino-4,5,6,7-tetrabromo-1H-benzimidazole (DMAT), which
