GYKI 52466 is a 2,3-benzodiazepine that acts as an ionotropic glutamate receptor antagonist, which is a non-competitive AMPA receptor antagonist (IC50 values are 10-20, ~ 450 and >> 50 μM for AMPA-, kainate- and NMDA-induced responses respectively), orally-active anticonvulsant, and skeletal muscle relaxant.[1][2][3][4] Unlike conventional 1,4-benzodiazepines, GYKI 52466 and related 2,3-benzodiazepines do not act on GABAA receptors.[5] Like other AMPA receptor antagonists, GYKI 52466 has anticonvulsant and neuroprotective properties.[6]
