Abstract:
AIMTo test the antiepileptic effect of phencynonate hydrochloride and investigate its antiepileptic mechanism.
METHODSThrough establishment of different epilepsy models, antiepileptic effects of phencynonate hydrochloride and other drugs were examined. Besides, the effect of phencynonate hydrochloride and other compounds against NMDA-induced lethality in mice, NMDA-induced injury in rat primary hippocampal neuronal cultures and NMDA-induced current were also observed.
RESULTSPhencynonate hydrochloride produced a significant anticonvulsant effect on different epilepsy models. Furthermore, phencynonate hydrochloride also exerted its obvious protection against the lethal effects of NMDA in mice, antagonized the NMDA-induced injury in rat primary hippocampal neuronal cultures and blocked NMDA-induced current in a dose-dependent manner.
CONCLUSIONPhencynonate hydrochloride had a notable anticonvulsant effect on typical epilepsy models, its antiepileptic mechanism might relate to its antagonism against NMDA receptor.
