CHIR-98014
CHIR-98014 is a potent inhibitor of GSK-3α and GSK-3β with IC50 values of 0.65 nM and 0.58 nM, respectively [1]
GSK-3 (Glycogen synthase kinase 3) is a serine/threonine protein kinase and plays a pivotal role in a number of central intracellular signaling pathways, including cellular proliferation, migration, inflammation and immune responses, glucose regulation, and apoptosis. Recently, it has been reported that GSK-3 abnormally expressed in a variety of diseases, including Type II diabetes, Alzheimer's Disease, inflammation, cancer, and bipolar disorder [2, 3].
CHIR-98014 is a potent GSK-3α and GSK-3β inhibitor. When tested with insulin receptor-expressing CHO-IR cells or primary rat hepatocytes, CHIR-98014 stimulated the GS activity ratio as high as two- to three fold compared with basal in a dose dependent manner. Similarly, in isolated type 1 skeletal muscle from insulin-sensitive lean Zucker and from insulin-resistant ZDF rats, administration of CHIR-98014 activated GS activity ratio [1]. In mouse ES-D3 cells, CHIR-98014 treatment (48 and 72 hours later) resulted in a significant activation of the Wnt/beta-catenin pathway via inhibiting GSK-3 [4].
In markedly diabetic and insulin-resistant db/db mice model, oral administration of CHIR-98014 (30mg/kg) significantly reduced fasting hyperglycemia within 4 hours and improved glucose disposal during an ipGTT [1].
