Description

General description

A cell-permeable and reversible Alsterpaullone (Cat. No. 126870) derivative that acts as a highly potent, ATP-competitive, selective inhibitor of Cdk1/cyclin B and GSK-3β (IC₅₀ = 230 pM and 800 pM, respectively; [ATP] = 15 µM). Displays ~37-fold greater selectivity for Cdk1/cyclin B over Cdk5/p25 (IC₅₀ = 30 nM). Shown to inhibit other kinases in a commercially available testing screen panel (pIC₅₀ = −logIC₅₀[M]; pIC₅₀ = ~ 7.5, 7.0, 7.0, 6.5, 6.5, 6.0, and 6.0 for Cdk2/A, Cdk4/D1, GSK-3β, PDGFRβ, Src, VEGFR-2, and VEGFR-3, respectively; [ATP] = 1 µM).

A cell-permeable and reversible Alsterpaullone (Cat. No. 126870) derivative that acts as a highly potent and ATP-competitiveinhibitor of Cdk/GSK-3 family serine/threonine kinases (IC₅₀ = 230 pM and 800 pM for cdk1/cyclin B and Gsk-3β, respectively; [ATP] = 15 µM). Displays ~130-fold greater selectivity for Cdk1/cyclin B over Cdk5/p25 (IC₅₀ = 30 nM). Shown to inhibit tyrosine kinases only at higher concentrations (pIC₅₀ = −logIC₅₀[M]; pIC₅₀ ~7.5, 7.0, 7.0, 6.5, 6.5, 6.0, and 6.0 for Cdk2/A, Cdk4/D1, GSK-3β, PDGFRβ, Src, VEGFR-2, and VEGFR-3, respectively; [ATP] = 1 µM).
