This compound is primarily utilized in neuroscience research to study the function and regulation of N-methyl-D-aspartate (NMDA) receptors. It acts as an antagonist, blocking the activity of these receptors, which are crucial for synaptic plasticity and memory formation. By inhibiting NMDA receptor activity, researchers can investigate the role of these receptors in various neurological conditions, such as epilepsy, neurodegenerative diseases, and chronic pain. Additionally, it serves as a valuable tool in understanding the mechanisms underlying excitotoxicity, a process linked to neuronal damage in stroke and traumatic brain injury. Its application extends to pharmacological studies aimed at developing therapeutic agents targeting NMDA receptor dysfunction.
