Biological Activity
Novel subtype-selective and weakly desensitizing AMPA receptor partial agonist (Ki 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 (EC50 values are 24.9 and 13.9 μM respectively) and is excitotoxic in vitro.
