Description

D4476 is a potent, selective and cell-permeable inhibitor of casein kinase 1(CK1) with an IC50 value of 0.3 μM in vitro.

IC50 & Target[1]

CK1

0.3 μM (IC50)

In Vitro

D4476 is a potent and rather selective inhibitor of CK1 in vitro and in cells. In H4IIE hepatoma cells, D4476 specifically inhibits the phosphorylation of endogenous forkhead box transcription factor O1a (FOXO1a) on Ser322 and Ser325 within its MPD, without affecting the phosphorylation of other sites. CK1δ assayed at 0.1 mM ATP using a phosphorylated peptide TFRPRTSpSNASTIS corresponding to residues 312–325 of FOXO1a is inhibited with an IC50 value of 0.3 μM. The IC50 value for CK1δ decreases progressively as the concentration of ATP is lowered, indicating that D4476 is an ATP-competitive inhibitor of CK1. CK1[1].

Cell Assay
[2]

D4476 is used for inhibition of Csnk1a1. D4476 is added to leukemia cells cultured in 96-well plates (5,000 cells per well) in medium supplemented with 10 ng/mL mIL-3. A D4476 dose titration is performed by adding 2.5 µM, 5 µM, 10 µM, 20 µM, and 40 µM D4476 to cell cultures in a final DMSO percentage of 0.4%. Similarly, D4476 is added to LSK cells cultured in SFEM medium supplemented with mTpo and mScf. The number of cells after 96 h of treatment is assessed with CountBright absolute counting beads using flow cytometry[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
