Description

PF-670462 2HCl is a potent inhibitor of the CK1 isoforms CK1ε and CK1δ (IC50 = 7.7 and 14 nM, respectively). Inhibition of CKIepsilon yields a perturbation of oscillator function that forestalls light as a zeitgeber, and they demonstrate that pharmacological tools such as PF-670462 may yield valuable insight into clock function. Casein kinase Iepsilon (CKIepsilon) is an essential component of the biological clock, phosphorylating PER proteins, and in doing so regulating their turnover and nuclear entry in oscillator cells of the suprachiasmatic nucleus (SCN).

How to use

In Vitro:

PF-670462 is a potent and selective inhibitor of CKIε and CKIδ, with IC50s of 7.7 nM and 14 nM, respectively. PF-670462 shows less than 30-fold selevtivity for EGFR and SAPK2A/p38, with IC50s of 150 nM and 190 nM, respectively. PF-670462 also causes a redistribution of the GFP signal to the cytoplasm in a concentration-dependent manner, with an EC50 of 290 ± 39 nM in CKIε-transfected COS7 cells. PF-670462 is a potent inhibitor of Wnt/β-catenin signaling, with an IC50 of ∼17 nM. PF-670462 (1 μM) is a weak inhibitor of proliferation, and only modestly suppresses the growth of HEK293 and HT1080 cells. PF-670462 (100 nM) strongly inhibits CK1ε and CK1δ, consistent with its effect on Wnt/β-catenin signaling.

In Vivo:

PF-670462 (50 mg/kg, s.c.) produces robust phase delays, and the activity remains persistent, with no discernible correction in the absence of exogenous zeitgebers in rats. PF-670462 (25, 50, and 100 mg/kg, s.c.) induces dose-dependent phase shift[1]. PF-670462 (50 mg/kg; s.c.) significantly phase delays the rhythmic transcription of Bmal1, Per1, Per2 and Nr1d1 in both liver and pancreas by 4.5 ± 1.3 h and 4.5 ± 1.2 h, respectively, 1 day after administration. In the suprachiasmatic nucleus (SCN), the rhythm of Nr1d1 and Dbp mRNA expression is also delayed by 4.2 and 4 h, respectively.
