Английская Википедия:AP-7 (drug)
Шаблон:Chembox AP-7 is a selective NMDA receptor (NMDAR) antagonist that competitively inhibits the glutamate binding site and thus activation of NMDAR. It has anticonvulsant effects.[1]
AP-7 functions specifically as a NMDA recognition site blocker, in contrast with 7-chlorokynurenate, which acts as a glycine site modulation blocker.[2]
Animal studies
AP-7 injected directly into the dorsal periaqueductal grey (DPAG) of rats produced an anxiolytic effect, whereas direct injection outside of the DPAG did not elicit anxiolytic effects. This suggests that a portion of systemically taken NMDA antagonist's anxiolytic effects comes from the DPAG region of the brain, at least in rats.[3]
The DPAG of the brain is thought to deal with fear-like defensive behavior via NMDA and glycine B receptors.[4] These excitatory glutamate receptors work with the inhibitory GABA receptors to achieve equilibrium in the DPAG of the brain.[5]
AP-7 has been known to cause muscle rigidity and catalepsy in rats following bilateral microinjections (0.02-0.5 nmol) into the globus pallidus and ventral-posterior portions of the caudate-putamen.[6]
The optically pure D-(−)-2-amino-7-phosphonoheptanoic acid [D-AP7], has also been examined. In groups of hypoxia-treated rats, D-AP7 enhanced motility, exhibited anxiogenic-like effect and impaired consolidation in passive avoidance. Both AP-7 and D-AP7 function as potent, specific antagonists of the NMDA receptor.[7]
