Used in neurological research for its potential neuroprotective properties, particularly in models of excitotoxicity and neurodegenerative conditions. Acts as a selective antagonist of the NMDA receptor, specifically targeting the GluN2B subunit, which helps modulate glutamate signaling without completely blocking NMDA receptor function. Investigated for possible therapeutic applications in stroke, traumatic brain injury, and chronic pain due to its ability to reduce neuronal damage linked to excessive glutamate activity. Also explored in psychiatric research for cognitive and mood-related disorders.
