Description

General description

A cell-permeable pyrazolopyrimidinylamino compound that acts as a potent, ATP-competitive and reversible inhibitor of CKIε with ~22-fold greater potency over CKIδ (IC₅₀ = 32 and 711 nM, respectively) and displays excellent selectivity among 50-kinases, with the only exception of EGFR (69% inhibition at 1 µM). Shown to preferentially block PER3 (PERIOD3) nuclear translocation in COS7-GFP-PER3-CKIε cells over CKIδ-transfected cells (IC₅₀ = 0.13 and 2.65 µM, respectively), and PER2 degradation in COS7-GFP-PER2-CKIε cells. Unlike Casein Kinase I Inhibitor II, PF-670462 (Cat. No. 218716), PF-4800567 exerts only marginal effect on circadian clock under similar conditions.
