UBP 296 is a novel, potent and selective kainate receptor antagonist.
ChEBI: 2-[[3-(2-amino-2-carboxyethyl)-2,6-dioxo-1-pyrimidinyl]methyl]benzoic acid is an alpha-amino acid.
Selective and potent GluR5-subunit containing kainate receptor antagonist (apparent K D = 1.09 mM). 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 fibres.
