Description

CHIR99021, CHIR-73911, also known as CT-99021, or CHIR-911, is an orally active and potent GSK3 inhibitor. CHIR-73911 exhibited GSK3 IC50 in the low nanomolar range and excellent selectivity. CHIR-73911 activates glycogen synthase in insulin receptorexpressing CHO-IR cells and primary rat hepatocytes.

How to use

In Vitro:

CHIR99021 inhibits human GSK-3β with Ki values of 9.8 nM[1]. CHIR99021 is a small organic molecule that inhibits GSK3α and GSK3β by competing for their ATP-binding sites.In vitro kinase assays reveal that CHIR99021 specifically inhibits GSK3β (IC50=~5 nM) and GSK3α (IC50=~10 nM), with little effect on other kinases. In the presence of CHIR99021 the viability of the ES-D3 cells is reduced by 24.7% at 2.5 μM, 56.3% at 5 μM, 61.9% at 7.5 μM and 69.2% at 10 μM CHIR99021 with an IC50 of 4.9 μM.

In Vivo:

In ZDF rats, a single oral dose of CHIR99021 (16 mg/kg or 48 mg/kg) rapidly lowers plasma glucose, with a maximal reduction of nearly 150 mg/dl 3-4 h after administration. CHIR99021 (2 mg/kg) given once, 4 h before irradiation, significantly improves survival after 14.5 Gy abdominal irradiation (ABI). CHIR99021 treatment significantly blocks crypt apoptosis and accumulation of p-H2AX+ cells, and improves crypt regeneration and villus height. CHIR99021 treatment increases Lgr5+ cell survival by blocking apoptosis, and effectively prevents the reduction of Olfm4, Lgr5 and CD44 as early as 4 h.
