Introduction
CHIR99021 (≥98%,HPLC),casno:252917-06-9 is a potent and selective inhibitor of glycogen synthase kinase-3β (GSK3β, IC50 = 5 nM) and GSK3α (IC50 = 10 nM)1.possibly by blocking induction of C/EBPα and PPARγ, and mimics Wnt signaling in 3T3-L1 preadipocytes. CHIR99021 activates glycogen synthase in CHO-IR cells with EC50 of 763 nM. CHIR99201 does not exhibit cross-reactivity against cyclin-dependent kinases (CDKs) with 350-fold selectivity toward GSK-3β compared to CDKs. Induces osteoblastogenesis, increases
mineralization and inhibits adipogenesis in ST2 cells2. Promotes replication and survival of pancreatic beta cells3. CHIR-99021
enhances differentiation and reduces proliferation of adult human olfactory epithelium neural precursors4. Cell permeable and active
in vivo.

In vitro study
CHIR99021 (≥98%,HPLC),casno:252917-06-9 inhibits human GSK-3β with Ki values of 9.8nM.CHIR-99021 is a small organic molecule that inhibits GSK3α and GSK3β by competing for their ATP-binding sites.In vitro kinase assays reveal that CHIR-99021 specifically inhibits GSK3β(IC50=~5nM) and GSK3α(IC50=~10nM),with little effect on other kinases. In the presence of CHIR-99021 the viability of the ES-D3 cells is reduced by 24.7%at 2.5μM,56.3% at 5μM,61.9% at 7.5μM and 69.2% at 10μM CHIR-99021 with an IC50 of 4.9μM.

In vivo study
In ZDF rats, a single oral dose of CHIR99021,casno:252917-06-9 (16mg/kg or 48mg/kg) rapidly lowers plasma glucose, with a maximal reduction of nearly 150mg/dl3-4h after administration.CHIR99021 (2mg/kg) given once,4h before irradiation, significantly improvs survival after 14.5Gy
abdominal irradiation.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 4h.
