APV ((2"R")-amino-5-phosphonovaleric acid; AP5, (2"R")-amino-5-phosphonopentanoate) is a selective NMDA receptor (NMDAR) antagonist that competitively inhibits the active site of NMDAR. [Morris RG. Synaptic plasticity and learning: selective impairment of learning rats and blockade of long-term potentiation in vivo by the N-methyl-D-aspartate receptor antagonist AP5. "Journal of Neuroscience". 1989 Sep;9(9):3040-57. PMID 2552039]

APV blocks the cellular analog of classical conditioning in the sea slug "Aplysia californica", and has similar effects on "Aplysia" long-term potentiation, since NMDA receptors are required for both. It is sometimes used in conjunction with the calcium chelator BAPTA to determine whether NMDARs are required for a particular cellular process.

APV is generally very fast acting within "in vitro" preparations, and can block NMDA receptor action at a reasonably small concentration. The active isomer of APV is considered to be the D configuration, although many preparations are available as a racemic mixture of D- and L-isomers. It is useful to isolate the action of other glutamate receptors in the brain, i.e. AMPA and kainate receptors.

APV can block the conversion of a silent synapse to an active one, since this conversion is NMDA receptor-dependent.

APV was developed by Jeff Watkins and Harry Olverman.
