Biochem/physiol Actions

EU1794-27 is an N-methyl-d-aspartate (NMDA) receptor (NMDAR) positive allosteric modulator (PAM) toward GluN2A/B/C subtypes (EC50/Emax = 1.4 μM/130%/GluN2B, 2.8 μM/230%/GluN2C, 2.4 μM/250%/GluN2D with Glu/Gly = ECmax = 100/30 μM using xenopus oocytes co-expressing rat GluN1 and respective GluN2 subtype; EC50/Emax = 6.3 μM/400%/GluN2B, 5.0 μM/680%/GluN2C with Glu/Gly = 1/0.3 μM &,;2.4 μM/580%/GluN2D with Glu/Gly = 0.6/0.2 μM), while it exhibits Glu/Gly level-dependent GluN1-GluN2A-modulating activities (EC50/Emax = 7.4 μM/52%/GluN2A with Glu/Gly = 100/30 μM; 8.1 μM/340% with Glu/Gly = 2/0.6 μM).
NMDA receptor is important for glutamate neurotransmission. It is associated with learning ability and memory. NMDA receptor possesses two different subunits NMDAR1 and NMDAR2. Tyrosine phosphorylation controls the actions of NMDA receptors. It is also known to influence neuronal function.

N-methyl-d-aspartate receptors (NMDARs) are an important receptor in the brain and have been implicated in multiple neurological disorders. Many non-selective NMDAR-targeting drugs are poorly tolerated, leading to efforts to target NMDAR subtypes to improve the therapeutic index. We describe here
