Description

General description

A cell-permeable, highly potent, ATP-competitive, reversible inhibitor of both GSK-3α and β (IC₅₀ = 650 and 580 pM, respectively).

A cell-permeable, brain permeant aminopyrimidine compound that acts as a potent, ATP-competitive and reversible inhibitor of both GSK-3α and β (IC₅₀ = 650 and 580 pM, respectively; K_i = 870 pM for human GSK-3β) and significantly affects downstream effects of GSK-3. Displays excellent selectivity over closely related Cdc2 and Erk2 (IC₅₀ = 3.7 µM & >10 µM, respectively). Does not affect the activity of several other protein kinases studied. Acutely sensitizes glycogen synthase activity in isolated skeletal muscle from insulin-sensitive lean Zucker and insulin-resistant Zucker diabetic fatty (ZDF) rats and can also augment insulin-stimulated glucose uptake in ZDF rats. However, it does not affect the basal glucose uptake rate. Induces a significant reduction in fasting hyperglycemia in diabetic and insulin-resistant db/db mice (~30 mg/kg, s.c.). Reduces Tau phosphorylation (Ser396) in the cortex and hippocampus of postnatal rats. Also shown to activate Wnt/β-catenin signaling and direct the differentiation of human pluripotent stem cells into cardiomyocytes.
