CP-465022Maleate 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-465022Maleate presents a valuable instrument for studying the involvement of AMPA receptors in various physiological and pathophysiological processes [1] [2].
