This compound is primarily used in neuroscience research as a selective antagonist for NMDA (N-methyl-D-aspartate) receptors. It helps in studying the role of these receptors in synaptic plasticity, learning, and memory processes. By blocking NMDA receptors, it allows researchers to investigate the mechanisms underlying excitatory neurotransmission and its impact on neurological disorders such as epilepsy, stroke, and neurodegenerative diseases. Additionally, it is utilized in experimental models to understand glutamate-mediated excitotoxicity and to explore potential therapeutic strategies targeting NMDA receptor dysfunction.
