Novel subtype-selective and weakly desensitizing AMPA receptor partial agonist (K i values are 44, 109, 223, 1890 and 2090 nM at GluR5, GluR1, GluR2, GluR3 and GluR4 receptors respectively). Exhibits potent agonist activity at GluR1 and GluR2 subunit-containing AMPA receptors (EC 50 values are 24.9 and 13.9 μM respectively) and is excitotoxic in vitro .
