D-AP5

D-AP5 is a selective N-methyl-D-aspartate (NMDA) receptor antagonist (Kd = 1.4 µM) that competitively inhibits the glutamate binding site of NMDA receptors. Whereas D-AP5 is the active (-)-stereoisomer, its (+)-isomer (L-AP5) demonstrates considerably less potent NMDA receptor antagonist activity. AP5 has been widely used to study the activity of NMDA receptors particularly in regard to researching synaptic plasticity, learning, and memory.Formal Name: 5-phosphono-D-norvaline.
