New ‘legal high’, the dissociative ephenidine, displaces MK-801 binding.
Ephenidine, like ketamine, blocks NMDA receptor mediated synaptic potentials and plasticity.
Ephenidine, like ketamine, blocks the NMDA receptor in a highly voltage-dependent manner.
Ephenidine blocks long-term potentiation, LTP.
NMDA receptor antagonism likely underlies the psychoactive effects of ephenidine.
