Description

General description

A potent cell-permeable, reversible, and ATP-compatible inhibitor of glycogen synthase kinase-3β (IC₅₀ = 22 nM) and cyclin-dependent kinases (IC₅₀ = 180 nM for Cdk1 and 100 nM for Cdk5). Inhibits the proliferation of a large range of cells by arresting them in the G₂/M phase of the cell cycle. Inhibits Tau phosphorylation in vitro and in vivo at Alzheimer′s disease-specific sites. Also reported to inhibit the in vivo phosphorylation of DARPP-32 by Cdk5 on Thr⁷⁵.
