DL-AP5 Sodium salt
Chemical Name: DL-2-Amino-5-phosphonopentanoic acid sodium salt
Biological ActivityDL-AP5 Sodium salt is the sodium salt of DL-AP5 (Cat. No. 0105) and a racemic mixture of the D- and L-isomers of AP5, a selective NMDA receptor antagonist that competes with glutamate binding and is commonly used to inhibit NMDA-dependent synaptic plasticity. D-AP5 (Cat. No. 0106) is the more active isomer and displays approximately 52-fold higher potency than the L-isomer, L-AP5 (Cat. No. 0107). In vitro D-AP5 reduces NMDA-induced depolarization of cortical neurons, with no effect on the response to L-Quisqualic acid (Cat. No. 0188) or Kainic acid (Cat. No. 0222). Following spinal injection of D-AP5, NMDA-response is rapidly reduced, with no effect seen on spontaneously active neurons.

DL-AP5 (40 micromolar) blocked spontaneous excitatory postsynaptic currents in an ex-vivo slice preparation.
This small molecule was used as NMDA glutamate site antagonist in ex-vivo patch clamp electrophysiology to investigate neuronal excitability.
