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[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.
