Description: Selective cell-permeable CK2 inhibitor
Alternative Names: NSC 231634
Chemical Name: 4,5,6,7-Tetrabromobenzotriazole
Purity: ≥98% (HPLC)
Biological Activity for TBB
TBB is a cell-permeable, selective inhibitor of casein kinase-2 (CK2) (IC50 = 0.9 and 1.6 μM for rat liver and human recombinant CK2 respectively). Exhibits modest discrimination between CK2 subunits, with Ki values ranging from 80 nM to 210 nM. Acts in an ATP/GTP-competitive manner and displays one to two orders of magnitude selectivity over a panel of 33 protein kinases.
Compound Libraries for TBB
TBB is also offered as part of the Tocriscreen 2.0 Max, Tocriscreen Kinase Inhibitor Library and Tocriscreen Antiviral Library. Find out more about compound libraries available from Tocris.
