Catalog Number: 2078
Chemical Name: (RS)-1-(2-Amino-2-carboxyethyl)-3-(2-carboxybenzyl)pyrimidine-2,4-dione
Biological Activity
Selective GluR5-subunit containing kainate receptor antagonist (apparent KD = 1.09 μM). Displays ~ 90-fold selectivity over AMPA receptors and recombinant human GluR6- and KA2-containing kainate receptors. Has little or no action at NMDA or group I mGlu receptors. Selectively blocks kainate receptor-mediated LTP induction in rat hippocampal mossy fibers.

Active Enantiomer also available.
