NMDA-IN-1 is primarily used in neuroscience research to study the role of NMDA receptors in various neurological processes. It acts as an inhibitor of NMDA receptors, which are crucial for synaptic plasticity and memory function. Researchers utilize this compound to investigate the mechanisms underlying conditions such as Alzheimer's disease, epilepsy, and neuropathic pain. By blocking NMDA receptor activity, NMDA-IN-1 helps in understanding how overactivation of these receptors contributes to excitotoxicity and neuronal damage. Additionally, it is employed in preclinical studies to explore potential therapeutic strategies for neurological disorders by modulating NMDA receptor function.
