Used primarily in neuroscience research, this compound acts as a selective antagonist for the glycine site on the NMDA receptor. It helps in studying the role of NMDA receptors in various neurological processes, including synaptic plasticity, learning, and memory. Additionally, it is utilized in experimental models to investigate conditions like epilepsy, neurodegenerative diseases, and chronic pain, providing insights into potential therapeutic targets. Its application extends to pharmacological studies where it aids in understanding the modulation of excitatory neurotransmission.
