Description

General description

A cell-permeable aminopyrimidine compound that acts as potent, ATP-competitive, and highly selective GSK-3 inhibitor (IC₅₀ = 10 and 6.7 nM against GSK-3α and GSK-3β, respectively). Exhibits little or no activity toward 46 other enzymes (IC₅₀ >8.8 µM against 20 kinases and K_i ≥5 µM against 23 non-kinase enzymes) and shows only weak binding to 22 pharmacologically relevant receptors (K_d ~4 µM). This compound is orally available and is shown to effectively improve glucose metabolism in both murine and rat type 2 diabetes models in vivo. The solid form of this compound (Cat. No. 361559) is also available.
