Description and Uses

Glycogen synthase kinase 3 (GSK3) is a serine/threonine kinase that plays a key inhibitory role in both the insulin and Wnt signaling pathways. CHIR99021 is an aminopyrimidine derivative that inhibits GSK3α and GSK3β with IC₅₀ values of 10 and 6.7 nM, respectively. When tested against twenty different protein kinases, this inhibitor shows greater than 500-fold selectivity for GSK3. CHIR99021 activates glycogen synthesis in CHO-IR cells (EC₅₀ = 0.8 μM) and in isolated type 1 diabetic rat skeletal muscle. A single oral dose (30 mg/kg) of CHIR99021 enhances in vivo glucose metabolism in a rodent model of type 2 diabetes. CHIR99021 has also been shown to induce the reprogramming of murine and human somatic cells into stem cells.
