应用
TBBz has been used as a CK2 inhibitor in HeLa cells and rat septal neurons.
生化/生理作用
Cell-permeable CK2 inhibitor.
TBBz is a cell-permeable Casein Kinase-2 (CK2) inhibitor. CK2 inhibitors, 4,5,6,7-tetrabromobenzotriazole (TBBt, Sigma Cat. # T0826) and rabromobenzimidazole (TBBz), the latter of which was shown to discriminate between different molecular forms of CK2 in yeast. TBBt, with a pK(a) ~5, exists in solution at physiological pH almost exclusively (>99%) as the monoanion; whereas TBBz, with a pKa ~9, is predominantly (>95%) in the neutral form, both of obvious relevance to their modes of binding. In vitro, TBBt inhibits different forms of CK2 with Ki values ranging from 80 to 210 nM. TBBz discriminates better between CK2 forms, with Ki values ranging from 70-510 nM. TBBz is more effective than TBBt in inducing apoptosis and to a lesser degree, necrosis in transformed human cell lines. Dvelopment of shRNA strategies for the selective knockdown of the CK2α and CK2α′ isoforms reinforces the foregoing results, indicating that inhibition of CK2 leads to attenuation of proliferation.
制备说明
TBBz is soluble in DMSO (60 deg C) at a concentration that is greater than 10 mg/ml.

The combination of bone morphogenetic protein 7 (BMP7) and neurotrophins (e.g. brain-derived neurotrophic factor, BDNF) protects septal neurons during hypoglycemic stress. We investigated the signaling mechanisms underlying this synergistic protection. BMP7 (5 nM) increased phosphorylation and nuclear translocation of BMP-responsive

Recently protein kinases have emerged as some of the most promising drug targets; and therefore, pharmaceutical strategies have been developed to inhibit kinases in the treatment of a variety of diseases. CK2 is a serine/threonine-protein kinase that has been implicated

Protein kinase CK2 has emerged as a promising candidate for the treatment of a number of cancers. This enzyme is comprised of two catalytic subunits (CK2 and/or CK2α') that form complexes with homodimers of regulatory CK2β subunits. While catalytic and

Despite the encouraging results of the innovative therapeutic treatments, complete remission is uncommon in patients affected by chronic lymphocytic leukaemia, which remains an essentially incurable disease. Recently, clinical trials based on BH3-mimetic drugs showed positive outcomes in subjects with poor

Hepatitis C virus (HCV) nonstructural protein 5A (NS5A) is a phosphoprotein with key functions in regulating viral RNA replication and assembly. Two phosphoisoforms are discriminated by their different apparent molecular weights: a basally phosphorylated (p56) and a hyperphosphorylated (p58) variant.
