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.

Twelve novel conformationally constrained homologues of glutamic acid have been synthesized and pharmacologically characterized at ionotropic glutamate receptors (iGluRs). Synthesis of the target compounds involved 1,3-dipolar cycloaddition of nitrile oxides to suitable dipolarophiles. The structure to the compounds has been

Activation of beta-adrenergic receptors (beta-ARs) enhances hippocampal memory consolidation and long-term potentiation (LTP), a likely mechanism for memory storage. One signaling pathway linked to beta-AR activation is the cAMP-PKA pathway. PKA is critical for the consolidation of hippocampal long-term memory

Excitation in neural circuits must be carefully controlled by inhibition to regulate information processing and network excitability. During development, cortical inhibitory and excitatory inputs are initially mismatched but become co-tuned or balanced with experience. However, little is known about how
