PEPA is an allosteric potentiator of AMPA desensitization. PEPA decreases the rate of onset of desensitization and potentiates steady-state equilibrium currents induced by Glu with splic variant and subunit selectivity. PEPA enhances post-ischemic memory impairment in rats post i.v. administration. AMPA is a transmembrane glutamate receptor composed of the subunits GluR-1,2,3,4. PEPA is an activator of GluR.
