一般說明
A cell-permeable halogenated benzimidazole compound that acts as a selective and ATP competitive inhibitor of casein kinase II (CK2, Ki = 70 nM for the active hetero-tetrameric form). However, its effect on free CK2a and CK2a′ subunits is significantly reduced (Ki = 510 and 400 nM, respectively). Reported to reduce viability and proliferation in HeLa, Jurkat, and HL-60 cells (at ˜25 µM). Also shown to disrupt the promoter activity of CYP24A1 and down-regulates its endogenous and 1, 25-Vitamin D3 (1,25-D3)-induced expression in PC3 cells. Synergistically enhances the anti-tumor effect of 1, 25-D3 in a PC3 xenograft murine model.

Vitamin D has broad range of physiological functions and antitumor effects. 24-Hydroxylase, encoded by the CYP24A1 gene, is the key enzyme for degrading many forms of vitamin D including the most active form, 1,25D(3). Inhibition of CYP24A1 enhances 1,25D(3) antitumor

Two ATP-competitive inhibitors-4,5,6,7-tetrabromo-benzotriazole (TBBt) and 4,5,6,7-tetrabromo-benzimidazole (TBBz) have been shown to decrease activity of CK2 holoenzyme. Surprisingly it occurs that TBBz contrary to TBBt does not inhibit free catalytic subunit CK2 [Formula: see text]. Both inhibitors are virtually inactive against

The development of selective cell-permeable inhibitors of protein kinase CK2 has represented an important advance in the field. However, it is important to not overlook the existence of discrete molecular forms of CK2 that arise from the presence of distinct

Like the previously reported 4,5,6,7-tetrabromobenzotriazole (TBBt), the structurally related 4,5,6,7-tetrabromobenzimidazole (TBBz) is a selective ATP-competitive inhibitor of protein kinase CK2 from such divergent sources as yeast, rat liver, Neurospora crassa and Candida tropicalis, with K(i) values in the range 0.5-1

Several halogeno benzimidazole riboside inhibitors of animal and plant protein kinases CK I and CK II (also known as casein kinases I and II), were found to be effective inhibitors of Saccharomyces cerevisiae CK II, but not of the 27-kDa
