Application

PEAQX tetrasodium hydrate has been used N-methyl-D-aspartate (NMDA) receptor 2A (NR2A) antagonist in rats and mice.

Biochem/physiol Actions

PEAQX is more specific for N-methyl-D-aspartate (NMDA) receptor 2A (NR2A) than N-methyl-D-aspartate (NMDA) receptor 2B (NR2B) and induces striatal apoptosis. It is less potent in activating caspase-3 than its stereomer NVP-AAM007.
NMDA receptor antagonist.

NMDA antagonists derived from 5-phosphonomethyl-1,4-dihydroquinoxaline-2,3-dione (3a) are potent anticonvulsant agents, and display strong protective effects in the electroshock-induced convulsion assay in mice. Their preference for the human NMDAR 1A/2A over 1A/2B subunit composition was optimized, leading to (1RS,1'S)-PEAQX (9r), which
