Description

General description

Mixture of two isomers. Potent inhibitor of protein phosphatases and useful for studies involving protein phosphorylation. Inhibits protein phosphatase 1 (IC₅₀ = 1 nM), protein phosphatase 2A (IC₅₀ = 10 nM), and smooth muscle endogenous phosphatase (IC₅₀ = 6 nM). Higher concentrations are needed to inhibit protein phosphatase 2B. Does not inhibit protein phosphatase 2C or phorbol dibutyrate binding. Does not activate protein kinase C or inhibit myosin light chain kinase.
