NYX-2925 enhances synaptic plasticity, long-term potentiation, metaplasticity, structural plasticity, learning ability, memory capacity and circadian rhythm amplitude. NYX-2925 regulates the signaling pathways of Src kinase, EIF2, mTOR, CDK5 and protein kinase A (PKA). NYX-2925 increases the levels of PSD-95, GluA1, activated Src and synaptic GluN2B. NYX-2925 is used in the research of neuropathic pain, fibromyalgia, painful diabetic peripheral neuropathy, post-traumatic stress disorder, cognitive impairment, depression, age-related cognitive decline and NMDAR-mediated central nervous system diseases.

NYX-2925 potently activates human recombinant NMDAR NR2A-D subtypes expressed in human embryonic kidney cells with EC50 values of 0.028-55 pM[3].
NYX-2925 robustly facilitates NMDAR current and NMDAR-dependent LTP in brain slices by activating the NMDAR[6].
NYX-2925 (0.1 pM-30 nM; 30-60 min) increases synaptic GluN2B (measured by colocalization with PSD-95) via an NMDAR-dependent, ion flux-independent mechanism after 30 min co-treatment with glutamate in primary hippocampal neurons derived from embryonic day 18 Sprague-Dawley rat pups, while higher concentrations have no effect or reduce synaptic GluN2B with prolonged exposure[7].
NYX-2925 (1 pM-30 nM; 1 min) enhances NMDA-induced calcium transients in primary hippocampal neurons derived from embryonic day 18 Sprague-Dawley rat pups at 30 nM, while 1 pM and 1 nM NYX-2925 have no effect[7].
NYX-2925 (1 pM; 30 min) does not alter basal synaptic GluA1 levels but facilitates chemLTP-mediated synaptic GluA1 recruitment in primary hippocampal neurons derived from embryonic day 18 Sprague-Dawley rat pups, while NYX-2925 (30 nM; 30 min) increases basal synaptic GluA1 levels but does not further enhance chemLTP-mediated recruitment beyond chemLTP alone[7].
NYX-2925 (Varying concentrations; 15 min preincubation, 15 min with [3H] MK-801) acts as a functional glycine site agonist at human GluN1/GluN2A, GluN1/GluN2B, GluN1/GluN2C, and GluN1/GluN2D NMDA receptors expressed in HEK cells, with EC50 values ranging from 28 fM to 55 pM[8].
NYX-2925 shows no significant binding activity against 81 tested neuroactive receptors, demonstrating low off-target potential[3].
NYX-2925 (10 μM) shows no significant off-target binding to 81 tested CNS protein targets, indicating low potential for off-target activity[8].
NYX-2925 (1 pM; 30 min) modulates pathways linked to receptor stabilization and homeostatic plasticity in primary hippocampal neurons derived from embryonic day 18 Sprague-Dawley rat pups, while NYX-2925 (30 nM; 30 min) modulates pathways linked to synaptic long-term potentiation and receptor trafficking[7].

NYX-2925 (0.1-10 mg/kg; p.o.; single administration) significantly increases resting-state alpha-band quantitative electroencephalogram (qEEG) power, as well as 6-7 Hz electroencephalogram power during auditory tetanic stimulation; meanwhile, doses of 0.1 and 1 mg/kg enhance mismatch negativity (MMN), and doses of 1 and 10 mg/kg augment late long-term potentiation (aLTP), indicating that it promotes NMDAR-dependent synaptic plasticity in male Sprague-Dawley rats[4].

Additionally, NYX-2925 reverses pain-related affective disorders; these effects depend on NMDA receptors, and no efficacy is observed with intrathecal administration[5].

NYX-2925 (0.1-10 mg/kg; p.o.; single administration) exerts rapid and long-lasting analgesic effects in streptozotocin (STZ)-induced rat models of diabetic neuropathic pain, with the analgesic effects of the 3 mg/kg and 10 mg/kg doses persisting for up to 1 week[5].
NYX-2925 (0.1-10 mg/kg; p.o.; single administration) dose-dependently attenuates persistent pain responses in the formalin model of *Rattus norvegicus* (brown rat), with significant efficacy observed at doses of 1 and 10 mg/kg[5].
NYX-2925 (0.1-10 mg/kg; p.o.; single administration) exerts no analgesic effect in the rat tail-flick acute nociceptive pain model[5].
NYX-2925 (0.1-10 mg/kg; p.o.; single administration) dose-dependently increases non-rapid eye movement (NREM) sleep during the light period in both non-sleep-deprived and sleep-deprived Sprague-Dawley rats, with the effect induced by the 10 mg/kg p.o. dose lasting up to 3 days post-administration[6].
NYX-2925 (1 mg/kg; p.o.; single administration) reverses deficits in positive emotional learning, hedonic ultrasonic vocalizations (USVs), and play-seeking behaviors induced by sleep deprivation in Sprague-Dawley rats[6].
NYX-2925 (10 mg/kg; p.o.; single administration) enhances the amplitude and precision of circadian rhythms of spontaneous activity and positive affect, while inhibiting negative affect, in non-sleep-deprived Sprague-Dawley rats[6].
