UBP 302 is an effective and selective GLUK5-subunit-containing kainate receptor antagonist (apparent Kd=402 nM) and displays very little affinity on GluK2 kainatereceptors.
CP-465022 Maleate is a potent, selective, noncompetitive AMPA receptor antagonist with anticonvulsant activity. It effectively counters the Kainate-induced response in rat cortical neurons, exhibiting an IC 50 of 25 nM. As such, CP-465022 Maleate presents a valuable instrument for studying the involvement of AMPA receptors in various physiological and pathophysiological processes [1] [2].
AMPA receptor antagonist with weak activity at NMDA receptors and little activity at kainatereceptors.This compound is unstable in powder form and other related salt forms are recommended.
N-Methyl-D-aspartate (NMDA) receptors are Ca2+ permeable ligand-gated channels of the central nervous system that are activated after binding of the co-agonists glutamate and glycine. CAY10608 is a propanolamine that potently, selectively, and non-competitively antagonizes the NR2B subunit of NMDA receptors (IC50 = 50 nM). It does not inhibit NR1, NR2A, NR2C, and NR2D subunits and has no significant effects on α-amino-3-hydroxy-5-methyl-4-isoxazolepropioinic acid (AMPA) or kainatereceptors. CAY10608 is neuroprotective, since it prevents NMDA-triggered release of lactate dehydrogenase from cultured cortical neurons. Also, CAY10608, when administered intraperitoneally, reduces brain infarct volume resulting from transient ischemia via carotid artery occlusion.
L-803087 TFA is a highly potent and selective agonist of the somatostatin sst4 receptor, exhibiting a Ki value of 0.7 nM. It displays a remarkable selectivity, being over 280-fold more preferential for the sst4 receptor compared to other somatostatin receptors. Furthermore, L-803087 TFA promotes AMPA-mediated synaptic responses in hippocampal preparations and enhances kainate-induced seizures in mice.
NBQX, also known as FG9202, is an AMPA receptor antagonist. NBQX blocks AMPA receptors in micromolar concentrations (~10–20 µM) and also blocks kainatereceptors. In experiments, it is used to counter glutamate excitotoxicity. NBQX was found to have anticonvulsant activity in rodent seizure models. As the disodium salt, NBQX is soluble in water at high concentrations (at least up to 100 mM).
