Application

GYKI 52466 hydrochloride has been used as an α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor selective antagonist in cell viability assays to evaluate the specificity of kainate (KA) effect on cerebellar granule cells (CGCs). It has also been used as an AMPA blocker to study the function of glutamate in neuroadapted sindbis virus (NSV) -induced motor neuron death.

Biochem/physiol Actions

GYKI 52466 serves as an antagonist of several processes, mediated by glutamate.
Selective allosteric AMPA receptor antagonist; anti­convulsant; skeletal muscle relaxant.

Whole-cell recordings were used to study the antagonism of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-preferring and kainate-preferring receptors by 2,3-benzodiazepines. Current through kainate-preferring receptors was recorded in rat dorsal root ganglion (DRG) neuron-s, whereas AMPA receptor current was measured in cultured neurons from

Allosteric regulators of alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionate (AMPA) receptors include 2,3-benzodiazepines such as GYKI 52466 and GYKI 53655 and the chaotropic anion thiocyanate that inhibit, and benzothiadiazines such as cyclothiazide that potentiate AMPA receptor currents. Here we sought to determine whether the allosteric

In whole-cell voltage-clamp recordings from cultured rat hippocampal neurons, the 2,3-benzodiazepine GYKI 52466 was a potent antagonist of kainate- and AMPA-activated currents (IC50 values, 7.5 and 11 microM, respectively), but was inactive against N-methyl-D-aspartate (NMDA) or gamma-aminobutyric acid responses.
