General description

An imidazolo-oxindole compound that acts as a potent, ATP-binding site directed inhibitor of PKR. Shown to effectively inhibit RNA-induced PKR autophosphorylation (IC50 = 210 nM) and rescue PKR-dependent translation block (IC50 = 100 nM). Inactive control is also available (Cat. No. 527455). Shown to increase the late phase of long-lasting synaptic potentiation, and enhance long-term memory in mice. Also available as a 50 mM solution in DMSO (Cat. No. 527451).
