Mechanism of Action

Targets/IC50/Ki
GSK-3β [1]
(Cell-free assay)
0.58 nM
GSK-3α [1]
(Cell-free assay)
0.65 nM
In vitro
CHIR-98014 inhibits human GSK-3β with Ki of 0.87 nM. This compound is very effective in preventing murine and rat GSK-3. Although it acts as a simple competitive inhibitor of ATP binding, it displays from 500-fold to >1000-fold selectivity for GSK-3 versus 20 other protein kinases including Cdc2, ERK2, Tie-2 and KDR. This inhibitor prevents Cdc2 with IC50 of 3.7 μM. However, it reveals similar potency against the highly homologous ɑ and β isoforms of GSK-3, it is noteworthy that it strongly discriminated between GSK-3 and its closest homologs CDC2 and ERK2. Exposure of insulin receptor-expressing CHO-IR cells or primary rat hepatocytes to increasing concentrations of this chemical results in a two- to three-fold stimulation of the GS activity ratio above basal. The concentrations giving rise to half-maximal GS stimulation (EC50) is 106 nM and 107 nM for CHO-IR and rat hepatocytes, respectively. [1]
Kinase Assay
Kinase assays
Polypropylene 96-well plates are filled with 300 μL/well buffer (50 mM tris HCl, 10 mM MgCl2, 1 mM EGTA, 1 mM dithiothreitol, 25 mM β-glycerophosphate, 1 mM NaF, 0.01% BSA, pH 7.5) containing kinase, peptide substrate, and any activators. CHIR-98014 or controls are added in 3.5 μL of DMSO, followed by 50 μL of ATP stock to yield a final concentration of 1 μM ATP in all cell-free assays. After incubation, triplicate 100-μL aliquots are transferred to Combiplate eight plates containing 100 μL/well 50 μM ATP and 20 mM EDTA. After 1 hour, the wells are rinsed five times with PBS, filled with 200 μL of scintillation fluid, sealed, left 30 min, and counted in a scintillation counter. All steps are performed at room temperature.
In vivo
GSK-3 inhibitor CHIR-98014 activates the GS activity ratio in isolated type I skeletal muscle from insulin-sensitive lean Zucker and from insulin-ressitant ZDF rats. Soleus muscle isolated from ZDF rats shows significant resistance to insulin for activation of GS but responded to 500 nM of this compound to the same extent (40% increase) as muscle from lean Zucker rats. Notably, GS activation by insulin plus this chemical is additive in muscle from lean Zucker rats and greater than additive in muscle from the ZDF rats. Total GS activity is not altered by either this inhibitor or insulin in these cells and muscles. Meanwhile, this compound does not influence the insulin dose-response in muscle from lean animals. The reduction in hyperglycemia and improved glucose disposal are not limited to db/db mice and ZDF rats, as similar results are observed with ob/ob mice, diet-induced diabetic C57BL/6 mice, and glucose-intolerant SHHF rats treated with this chemical. [1] Additionally, this compound decreases the phosphorylation (Ser396) of tau protein in the cortex and hippocampus of postnatal rats. [2]
