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[1].
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[2].

The recombinant CK1ε phosphorylates Thr1479 of GST-LRP6 mini fragment in vitro, and TPA enhances CK1ε kinase activity. GST-LRP6 mini fragment fusion protein was incubated with recombinant CK1ε in the presence of 200 μM ATP with or without 160 μM TPA or 2 μM PF-670462 dihydrochloride as indicated. The detection of the phosphorylation of Thr1479 was performed by immunoblotting using an anti–phospho-LRP6 (Thr1479) antibody. Thr1479 phosphorylation levels were quantitated by densitometry and normalized to GST-LRP6 mini levels. Quantitated results are displayed (Right). The results showed that PF670462 (specific CK1 inhibitor) markedly suppresses CK1ε-triggered LRP6 phosphorylation at Thr1479. Phosphorylation of Thr1479 is indicated by an asterisk.

TPA rescued the inhibitory effect of PF-670462 dihydrochloride on the kinase activity of CK1ε. The GST-LRP6 mini fusion protein was incubated with CK1ε in the absence or presence of 2 μM PF-670462 dihydrochloride or the indicated amounts of TPA. Thr1479 phosphorylation of GST-LRP6 mini was measured by immunoblotting using anti–phospho-LRP6 (Thr1479) antibody, indicated by p-LRP6 (Thr1479). Phosphorylation of Thr1479 is indicated by an asterisk.

Protocolo
The CKIε kinase assay is performed in a 40-μL final volume in buffer containing 50 mM Tris, pH 7.5, 10 mM MgCl2, 5 mM dithiothreitol with 5 μM ATP, 3 nM CKIεΔ319, and 15 μM peptide substrate PLSRTLpSVASLPGL in the presence of 5 μL of CKIε inhibitor (PF-670462) or 5% dimethyl sulfoxide. The reaction is incubated for 3 h at 27°C; detection is carried out as described for the Kinase-Glo Assay. Luminescent output is measured[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Adult male CD rats (initial weight 175-225 g) are released into constant darkness (DD) for 2 weeks, and their individual free-running periods and times of activity onset are determined from the 7 to 10 days at the end of the 2-week period. Dosing of 50 mg/kg PF-670462 or vehicle (40% β-cyclodextrin) takes place at circadian time (CT)9 or 3 h before the predicted onset of activity; night vision goggles facilitated the subcutaneous administration. CT9 is chosen based on preliminary data demonstrating robust responses to CKIε inhibition at this circadian time. Animals are maintained under DD for an additional 4 to 5 days postdose, and the data from that time period are used in the estimation of the magnitude and direction of the putative phase shifts[1].
