Application

GYKI-53655 hydrate has been used as a calcium-permeable α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPA) receptor antagonist in single-particle tracking experiments.

Biochem/physiol Actions

GYKI-53655 also inhibits the kainate GluK3 homomeric and GluK2/3 heteromeric receptors. It exhibits anti-ischemic, anti-convulsant, and acute neuroprotective activity.
GYKI-53655 is an AMPA antagonist and noncompetitive negative allosteric modulator.
