Biological Activity

PF-4800567 is a selective, ATP competitive casein kinase 1ε inhibitor with IC50 values of 32 and 711 nM for CK1ε and CK1δ respectively. Casein kinase 1 epsilon (CK1epsilon) and casein kinase 1 delta (CK1delta) are closely related Ser-Thr protein kinases that serve as key clock regulators as demonstrated by mammalian mutations in each that dramatically alter the circadian period. PF-4800567 displays 22-fold greater potency towards CK1ε than CK1δ. PF-4800567 completely blocks CK1epsilon-mediated PER3 nuclear localization and PER2 degradation.

Method cell proliferation assay
Cell Lines HEK293 and HT1080 cell
Concentrations 1 μM
Incubation Time 24 h
Results We confirmed that PF480 selectively inhibited CK1ɛ using the in vivo autophosphorylation assay. PF480 was less effective than PF670 at inhibition of Wnt/β-catenin signaling
Cell Experiment
Cell lines COS-7 cells
Preparation method Nuclear Translocation.
CK1ϵ- and CK1δ-dependent PER3 nuclear translocation was run as described previously for CK1ϵ (Badura et al., 2007), with alterations as indicated below. CK1δ-dependent PER3 nuclear translocation was performed with human full-length CKIδ-pcDNA4/HisA cotransfected into COS-7 cells with the GFP-tagged murine PER3. The sensitivity of the assay was increased by incorporating an anti-GFP antibody-staining step. After the plates were fixed with 4% paraformaldehyde and washed in PBS, cells were blocked and permeabilized in PBS with 4% goat serum and 0.1% Triton X-100 for 1 h at room temperature. Blocking buffer was then replaced with a polyclonal anti-GFP antibody (Invitrogen), diluted 1:1000 in blocking buffer, and incubated for 2 h. After three washes in PBS, goat anti-rabbit Alexa Fluor 488 secondary antibody (Invitrogen), diluted 1:1000 in Hoechst staining solution, was added and incubated for 1 h before three final washes in PBS.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
