Description

General description

A cell-permeable and potent inhibitor of GSK-3β (IC₅₀ = 30 nM). Binds to GSK-3β with high-affinity (K_d = 126 nM), leading to an increase in the level of β-catenin, a downstream substrate of GSK-3β in the Wnt signaling pathway. Shown to selectively induce neuronal differentiation in both pluripotent murine embryonal carcinoma cells (P19; 30-40% at 1 µM) and embryonic stem cells (D3; 50-60% at 400 nM).

A cell-permeable pyrrolopyrimidine compound that acts as a potent inhibitor of GSK-3β (IC₅₀ = 30 nM). Binds to GSK-3β with high-affinity (K_d = 126 nM) and increases the level of β-catenin, a downstream substrate of GSK-3β in the Wnt signaling pathway. Shown to selectively induce neuronal differentiation in both pluripotent murine embryonal carcinoma cells (P19; 30-40% at 1 µM) and embryonic stem cells (D3; 50-60% at 400 nM).
