CGP 39551 is a potent, orally active, competitive N-methyl-D-aspartate (NMDA) receptor antagonist with potent anticonvulsant activity[1]. CGP 39551 shows measurable inhibitory activity at both L-[3H]-glutamate (Ki=8.4 μM)[2].

In Vitro	CGP 39551 inhibits the binding of the selective NMDA receptor antagonist, [3H]-CPP to rat brain postsynaptic densities (PSDs) with a Ki of 310 nM[2].
In Vivo	CGP 39551 exhibits maximal electroshock-induced seizures in mice with the ED50 of 4 mg/kg (p.o.)[2]. Following chronic neonatal treatment with CGP 39551, adult rats show increased behavioral responses to the D2 dopamine receptor stimulation[3].
