Laduviglusib trihydrochloride CHIR-99021 trihydrochloride; CT99021 trihydrochloride

产品介绍

Laduviglusib (CHIR-99021) trihydrochloride 是一种有效的选择性 GSK-3α/β 抑制剂，IC₅₀ 为 10 nM 和 6.7 nM。CHIR-99021 trihydrochloride 对 GSK-3 的选择性比 CDC2，ERK2 和其他蛋白激酶高 500 倍以上。Laduviglusib trihydrochloride 还是一种有效的 Wnt/β-catenin 信号通路激活剂。Laduviglusib trihydrochloride 可增强小鼠和人类胚胎干细胞的自我更新。Laduviglusib trihydrochloride 能诱导细胞自噬 (autophagy)。

生物活性

Laduviglusib (CHIR-99021) trihydrochloride is a potent and selective GSK-3α/β inhibitor with IC₅₀s of 10 nM and 6.7 nM. Laduviglusib trihydrochloride shows >500-fold selectivity for GSK-3 over CDC2, ERK2 and other protein kinases. Laduviglusib trihydrochloride is also a potent Wnt/β-catenin signaling pathway activator. Laduviglusib trihydrochloride enhances mouse and human embryonic stem cells self-renewal. Laduviglusib trihydrochloride induces autophagy.

体外研究

Laduviglusib trihydrochloride inhibits human GSK-3β with K_i values of 9.8 nM. Laduviglusib trihydrochloride is a small organic molecule that inhibits GSK3α and GSK3β by competing for their ATP-binding sites.In vitro kinase assays reveal that Laduviglusib trihydrochloride specifically inhibits GSK3β (IC₅₀=~5 nM) and GSK3α (IC₅₀=~10 nM), with little effect on other kinases^[4]. In the presence of Laduviglusib trihydrochloride 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 Laduviglusib trihydrochloride with an IC₅₀ of 4.9 μM.

体内研究

In ZDF rats, a single oral dose of Laduviglusib (16 mg/kg or 48 mg/kg) trihydrochloride rapidly lowers plasma glucose, with a maximal reduction of nearly 150 mg/dl 3-4 h after administration. Laduviglusib (2 mg/kg) trihydrochloride given once, 4 h before irradiation, significantly improves survival after 14.5 Gy abdominal irradiation (ABI). Laduviglusib trihydrochloride treatment significantly blocks crypt apoptosis and accumulation of p-H2AX⁺ cells, and improves crypt regeneration and villus height. Laduviglusib trihydrochloride treatment increases Lgr5⁺ cell survival by blocking apoptosis, and effectively prevents the reduction of Olfm4, Lgr5 and CD44 as early as 4 h^[5].
