Talampanel (LY300164) is a non-competitive antagonist of AMPA-receptor   .
The α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPA receptor) is a ionotropic transmembrane receptor for glutamate, which is involved in fast synaptic transmission in the central nervous system (CNS) .
Talampanel (LY300164) is a non-competitive AMPA-receptor antagonist. In primary rat hippocampal cultures, LY300164 dose-dependently attenuated kainic acid (KA)-excitotoxicity with IC50 value of 4 μM .
In male Mongolian gerbils with bilateral carotid artery occlusion, LY300164 (10 mg/kg) orally administration reduced responses to AMPA by 68% but reduced responses to NMDA only by 9%. LY300164 (10 mg/kg) administered orally or intravenously immediately after the occlusion exhibited good protection with 24% and 20% of the neurones surviving, respectively . In mice with transient focal cerebral ischemia/reperfusion, talampanel significantly reduced the infarct size by 33.1%. Also, talampanel significantly reduced the amount of TUNEL-positive cells and caspase-3 active cells .
