描述：

CHIR98014是一种有效的GSK-3α/β抑制剂，无细胞试验中IC50为0.65 nM/0.58 nM，作用于GSK-3比作用于其最密切的同源物Cdc2 和 ERK2选择性高。

溶解性：DMSO :8 mg/mL (16.45 mM)

体外研究：

CHIR-98014 inhibits human GSK-3β with Ki of 0.87 nM. CHIR-98014 is very effective in preventing murine and rat GSK-3. Although CHIR-98014 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. CHIR-98014 prevents Cdc2 with IC50 of 3.7 μM. However, CHIR 98014 reveals similar ptoency against the highly homologous ɑ and β isoforms of GSK-3, it is noteworthy that it stronly 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 inhibitor CHIR98014 results in a two- to three-fold stimulation of the GS activity ratio above basal. The concentrations of CHIR-98014 giving rise to half-maximal GS stimulation (EC50) is 106 nM and 107 nM for CHO-IR and rat hepatocytes, respectively.

体内研究：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 CHIR-98014 to the same extent (40% increase) as muscle from lean Zucker rats. Notably, GS activation by insulin plus CHIR-98014 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 CHIR-98014 or insulin in these cells and muscles. Meanwhile, CHIR-98014 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 CHIR-98014. Additionally, CHIR-98014 decreases the phosphorylation (Ser396) of tau protein in the cortex and hippocampus of postnatal rats.
