(R,S)-ATPA is a selective and potent GluR5 kainate receptor agonist (1,2). It inhibits GluK2 kainate receptor-JNK3 protein pathway by activating GABA type A receptor in rat after cerebral ischemia-reperfusion injury (3). (R,S)-ATPA is a neuroprotective agent.
ChEBI: 2-amino-3-(5-tert-butyl-3-oxo-4-isoxazolyl)propanoic acid is an alpha-amino acid.
A selective and potent GluR5 kainate receptor agonist (K i = 4.3 nM), inactive at GluR6 (K i > 1 mM) and only weakly active at AMPA receptors (GluR1-4) and the kainate receptors KA-2 and GluR7 (K i values of 6 - 14 μ M). Also available as part of the Kainate Receptor Tocriset™ .
