Casein Kinase I Inhibitor II, PF-670462 - CAS 950912-80-8 - Calbiochem

A cell-permeable tri-substituted imidazole compound that acts as a potent and reversible inhibitor of casein kinase Iε/δ (IC₅₀ = 7.7 and 14 nM, respectively) with modest to excellent selectivity over EGFR and p38 MAPK (IC₅₀ = 150 and 190 nM, respectively) and over 43 related kinases (IC₅₀ >0.3 to 30 µM), and a panel containing 116-receptors, transporters and other enzymes. Shown to inhibit PER3 nuclear translocation in GFP-PER3 and CKIε-cotransfected COS7 cells (EC₅₀ = 290 nM), and induce phase delays in circadian rhythms of monkeys & rats model (10 - 100 mg, s.c.); further, attenuate the locomotor stimulant response to methamphetamine.

Packaged under inert gas

Soluble in DMSO (<100 mM) or H2O ( <100 mM); aliquot & store at -20*C; stable for 6 months. Most likely to compete with ATP.
