GYKI 52466 dihydrochloride (GYKI 52466 2HCl) is a highly potent, orally active and selective AMPA/Kainate receptor antagonist with good blood-brain permeability and anticonvulsant activity that can be used to study neurological diseases such as Parkinson's and epilepsy.

SYM 2081 is a specific kainate receptor agonist with an IC50 value of 35 nM for [3H]-kainate binding. SYM 2081 depolarizes the muscle and reduces the EPSP amplitude.

cis-PDA (cis PDA) is a general ionotropic receptor antagonist. cis-PDA acts by blocking NMDA, AMPA, and kainate-mediated responses.

BPAM344 is a potent positive allosteric modulator (PAM) of the KAR subunits GluK1b, GluK2a, and GluK3a.

Fanapanel (ZK200775) is a quinoxalinedione derivative and potent competitive antagonist of AMPAR for cerebrovascular-related studies.

YM90K (6-(1H-imidazol-1-yl)-7-nitro-2,3(1H,4H)-) hydrochloride is an antagonist of AMPA receptor.

CNQX disodium is a competitive non-NMDA receptor antagonist and competitive AMPA/kainate receptor antagonist in neuronal cultures.

LY382884 is a selective and potent GluR5 kainate receptor antagonist with anxiolytic activity.LY382884 blocks blockade of mossy fibre LTP induction.

IEM 1754 2HBr (IEM 1754 dihydrobromide) is a selective AMPA/kainate receptor blockers for GluR1 and GluR3 with IC50 of 6 μM.

CP 465022 hydrochloride is a potent, and selective noncompetitive antagonist of AMPA receptor with anticonvulsant activity. CP 465022 hydrochloride inhibits Kainate-induced response with an IC50 of 25 nM in rat cortical neurons.

Unifiram is a nootropic agent.1It increases acetylcholine (ACh) release in the rat cerebral cortexin vivoand induces a long-lasting increase in the amplitude of field excitatory postsynaptic potentials (fEPSPs) in the rat hippocampal CA1 region (EC50= 27 nM). It does not bind to serotonin (5-HT), dopamine, muscarinic, nicotinic, adrenergic, glutamate, histamine, opioid, or GABA receptors at 1 μM. Unifiram (0.1 mg/kg) improves memory in non-memory-impaired rats in a social learning test.2It also prevents memory deficits induced by the anticholinergic agent scopolamine, nicotinic receptor antagonist mecamylamine, GABABreceptor agonist baclofen, or α2-adrenergic receptor agonist clonidine in the passive avoidance test in mice when administered at a dose of 0.01 mg/kg and prevents memory deficits induced by the AMPA/kainate glutamate receptor antagonist NBQX at 0.1 mg/kg.1 1.Romanelli, M.N., Galeotti, N., Ghelardini, C., et al.Pharmacological characterization of DM232 (unifiram) and DM235 (sunifiram), new potent cognition enhancersCNS Drug Rev.12(1)39-52(2006) 2.Ghelardini, C., Galeotti, N., Gualtieri, F., et al.The novel nootropic compound DM232 (unifiram) ameliorates memory impairment in mice and ratsDrug Develop.

CP-465022 Maleate is a potent, selective, noncompetitive AMPA receptor antagonist with anticonvulsant activity, effectively countering the Kainate-induced response in rat cortical neurons with an IC50 of 25 nM, making it a valuable instrument for studying the involvement of AMPA receptors in various physiological and pathophysiological processes [1] [2].

GluR5-containing kainate receptor antagonist

NS 3763 is a kainate receptor antagonist.

AMPA receptor antagonist with weak activity at NMDA receptors and little activity at kainate receptors

5-Iodowillardiine is a selective agonist for specific kainate receptor subunits that robustly activates GluK1 (GluR5) and GluK5 (KA2)-containing receptors while displaying minimal activity at AMPA receptors and no measurable agonism toward GluK2 (GluR6) subunits. Despite its excitotoxic neurotoxic activity in vivo, 5-Iodowillardiine remains a powerful experimental tool for dissecting kainate receptor subtype distribution, synaptic function, and excitatory neurotransmission in the brain and spinal cord.
