Biological Activity

Description TBB (4,5,6,7-tetrabromobenzotriazole) is a selective cell-permeable CK2 inhibitor with IC50 values of 0.9 and 1.6 μM for rat liver and human recombinant CK2 respectively.
Targets
CK2 [1]
(Cell-free assay)
CK1 [1]
(Cel-free assay)
0.4 μM(Ki) 47 μM(Ki)
In vitro
In vitro In the presence of 10 μM TBB (and 100 μM ATP) only CK2 was drastically inhibited (s85%) whereas three kinases (phosphorylase kinase, glycogen synthase kinase 3L and cyclin-dependent kinase 2/cyclin A) underwent moderate inhibition, with IC50 values one-two orders of magnitude higher than CK2 (IC50 = 0.9 μM). TBB discriminates between CK2 and CK1, being much more e¡ective with the former[1].
Cell Research Cell lines Jurkat cells
Concentrations 60 μM
Incubation Time 2 h
Method

Cell treatment was performed by incubation of cell suspension (~10×106 cells/ml) for 2 h at 37℃ in the presence of 2 μM okadaic acid (OA) with the addition of protein kinase inhibitors where indicated. After incubations, cells were centrifuged and lysed for 15 min in ice-cold buffer consisting of 20 mM Tris^HCl pH 7.4, 2 mM EDTA, 2 mM EGTA, 10 mM 2-mercaptoethanol, 10% (v/v) glycerol, 1 mM Na3VO4, 0.05% Nonidet P-40, protease inhibitor cocktail, 10 mM NaF, 1 μM OA. The lysate was cleared by centrifugation for 10 min at 14 000 rpm.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
