D-LAP5

D-LAP5 (D-2-Amino-5-phosphonopentanoic acid) is a competitive antagonist of NMDA receptors, specifically targeting the glutamate binding site. It is used extensively in neuroscience research to investigate excitotoxicity, synaptic transmission, and neuroprotection. NMDA receptor overactivation is a hallmark of several neurodegenerative diseases, and D-LAP5 helps elucidate the role of glutamatergic signaling in neuronal injury. Its application in electrophysiological and behavioral studies provides insights into learning, memory, and neurodegenerative mechanisms.
