GSK-3β Inhibitor VIII-CAS 487021-52-3-Calbiochem

C₁₂H₁₂N₄O₄S

MFCD08277040

A cell-permeable thiazole-containing urea compound that acts as a potent inhibitor of GSK-3. Shown to inhibit GSK-3β with high potency (IC₅₀ = 104 nM). Inhibition is competitive with respect to ATP (K_i = 38 nM). Specificity has been reported using a panel of 28 different kinases, including Cdk2 and Cdk5 (IC₅₀ >100 µM). Shown to prevent tau phosphorylation at a GSK-3-specific site. Also shown to protect neuronal cells against Aβ-mediated neurodegeneration in vitro and reduce tauopathy in mice in vivo (30 µmol/kg delivered with 40% PEG400 and 40% dimethylacetamide in water). Caution: Do not use delivering vehicles containing dimethylamine for in vivo studies, as it is highly toxic to animals. A 25 mM (5 mg/649 µl) solution of GSK-3β Inhibitor VIII (Cat. No. 361557) in DMSO is also available.
