Beschreibung

Allgemeine Beschreibung

Cell-permeable protein phosphatase 2A (PP2A) inhibitor (IC₅₀ = 0.5-1.0 nM). Also inhibits protein phosphatase 1 (PP1; IC₅₀ = 2 nM). A non-phorbol ester type tumor promoter that induces oxidative DNA damage. Selectively increases the efficacy of AMPA receptor-mediated synaptic transmission at excitatory synapses. Recently, it has been used to study the regulation of Ca²⁺-activated K⁺ channels in smooth muscle and to correlate shape changes in fibroblasts with the degree of protein phosphorylation. Also known to prevent γ-radiation induced apoptosis in Burkitt′s lymphoma cell line BM13674.
