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.

Mechanism of Action

Targets/IC₅₀/Ki	CK2 ^[1] (Cell-free assay) 0.4 μM(Ki) CK1 ^[1] (Cel-free assay) 47 μM(Ki)
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). This compound discriminates between CK2 and CK1, being much more e¡ective with the former^[1].
