Antagonism at NMDA receptor
By Sergiy Sylantyev on 11/29/2020
Application: Species: Human

PMPA was in use as an NMDA receptor antagonist affecting glutamate site, to study (possible) competition of dopamine for this site. Application of PMPA and dopamine mixtures in different ratios resulted in a decrease of single-channel NMDA receptor openings recorded from outside-out neuron membrane patches. No problem with dissolution in water up to 10 mM concentration.
