Description

General description

A cell-permeable inhibitor of protein phosphatase 2A (PP2A; IC50 = 0.5-1 nM) and 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. Also known to prevent γ-radiation induced apoptosis in Burkitt’s lymphoma cell line BM13674. Also available as a 100 µM solution in DMSO (Cat. No. 508226).
