| Catalog No.GC15642 |
Le trichlorhydrate de laduviglusib (CHIR-99021) est un puissant et sélectif GSK-3α/β inhibiteur avec des CI50 de 10 nM et 6,7 nM. Le trichlorhydrate de CHIR 99021 montre une sélectivité > 500 fois pour GSK-3 par rapport À CDC2, ERK2 et d'autres protéines kinases. Le trichlorhydrate de CHIR 99021 est également un puissant activateur de la voie de signalisation Wnt/β-caténine. Le trichlorhydrate de CHIR 99021 améliore l'auto-renouvellement des cellules souches embryonnaires de souris et humaines. Le trichlorhydrate de CHIR 99021 induit l'autophagie.

CHIR-99021 trihydrochloride (CT99021 trihydrochloride) is a GSK-3α/β inhibitor with IC50 of 10 nM/6.7 nM; >500-fold selectivity for GSK-3 versus its closest homologs CDC2 and ERK2, as well as other protein kinases.
CHIR-99021 inhibits human GSK-3β with Ki values of 9.8 nM[1]. 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=~5 nM) and GSK3α (IC50=~10 nM), with little effect on other kinases[2]. In the presence of CHIR-99021 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 CHIR-99021 with an IC50 of 4.9 μM[3].
In ZDF rats, a single oral dose of CHIR-99021 (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[1]. 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[4].
