D-AP5 (D-APV) is a selective and competitive NMDA receptor antagonist with a Kd of 1.4 μM. D-AP5 (D-APV) inhibits the glutamate binding site of NMDA receptors[1][2].

IC50 & Target


In Vivo

D-AP5 is a NMDA receptor antagonist. Chronic intraventricular infusion of D-AP5 causes a parallel dose-dependent impairment of spatial learning and long-term potentiation (LTP) in vivo. Intracerebral concentrations of D-AP5 fail to induce any measurable sensorimotor disturbance when spatial learning is prevented[2].
D-AP5 infusion is associated with a progressive reduction in swim speed over trials. D-AP5 causes sensorimotor disturbances in the spatial task, but these gradually worsened as the animals fail to learn. Rats treated with D-AP5 show a delay-dependent deficit in spatial memory in the delayed matching-to-place protocol for the water maze[3].
