CHIR 99021 trihydrochloride is hydrochloride of CHIR 99021, which inhibits GSK-3α and GSK-3β with IC50 values of 10 nM and 6.7 nM. GSK-3 is a serine/threonine kinase, responsible for phosphorylating either the serine or threonine residues of its substrates. This phosphorylation process is involved in various key biological processes, including gene transcription, protein synthesis, cell signaling, cellular transport, proliferation, apoptosis, intracellular communication and glucose regulation.

Cell lines
INS-1E cells
Reaction Conditions
0 ~ 20 μM CHIR 99021 for 24 h incubation
Applications
CHIR 99021 increased the rate of proliferation of INS-1E cells in a dose-dependent manner, with the rate of proliferation reaching a maximum in the presence of 2.5 ~ 10 μM CHIR 99021. Moreover, CHIR 99021 also dose-dependently counteracted INS-1E cell death induced by high glucose and high palmitate.
Animal models
Male ZDF rats with type 2 diabetes
Dosage form
16, 30 or 48 mg/kg
Orally
In ZDF rats with type 2 diabetes, a single oral dose of CHIR 99021 at 30 mg/kg rapidly lowered plasma glucose, with a maximal reduction of nearly 150 mg/dl 3 ~ 4 hours after administration, while plasma insulin remained at or below control levels. Moreover, oral administration of CHIR 99021 at 16 or 48 mg/kg 1 hour before oral glucose challenges in ZDF rats substantially improved glucose tolerance, with 14% and 33% reduction in plasma glucose.
