Fanapanel hydrate is a highly selective antagonist of AMPA kainate with little activity against NMDA(Ki of 3.2 nM, 100 nM, and 8.5 μM against quisqualate, kainate, and NMDA, respectively).
UBP 302 is an effective and selective GLUK5-subunit-containing kainate receptor antagonist (apparent Kd=402 nM) and displays very little affinity on GluK2 kainate receptors.
GYKI-52466 is a selective non-competitive AMPA receptor antagonist (IC50 values are 10-20, ~ 450 and >50 μM for AMPA-, kainate- and NMDA-induced responses, respectively) used as a Skeletal muscle relaxant, orally active anticonvulsant, neuroprotective and
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].
