Description

Application

D(-)-2-Amino-5-phosphonopentanoic acid has been used to pretreat BNST (bed nucleus of the stria terminalis) in order to block the induction of anxiety by ORX-A (orexin-A) into the BNST.

Biochem/physiol Actions

NMDA antagonists have muscle relaxation property and are known to offer neuron protection against brain damage induced by ischemia. 2-Amino-5-phosphonopentanoic acid has been proved to block the iontophoresis induced depolarization of NMDA.

Anticonvulsant; potent and selective N-methyl-D-aspartate (NMDA) receptor antagonist; active enantiomer of 2-amino-5-phosphonopentanoic acid.
