Cayman NVP-AAM077

NVP-AAM077 is an NMDA receptor antagonist (IC₅₀ = 0.008 µM). It is selective for NMDA receptors containing NR1A/NR2A subunits over NMDA receptors containing NR1A/NR2B subunits (IC₅₀s = 0.27 and 29.6 µM, respectively, in X. laevis oocytes expressing receptors containing the respective subunits). NVP-AAM077 inhibits seizures induced by maximal electroshock (MES) in mice with an ED₅₀ value of 23 mg/kg. It increases the activity of neuronal nitric oxide synthase (nNOS) in primary hippocampal neurons. NVP-AAM077 (10 mg/kg) inhibits proliferation of neural progenitor cells (NPCs) in the subventricular zone (SVZ) and in the subgranular zone (SGZ) of the hippocampal dentate gyrus of adult mice, an effect not seen in nNOS^-/- mice. It also increases the escape latency and decreases the percentage of time spent in the target quadrant in the Morris water maze.
