Used primarily in research, this compound serves as a selective antagonist for the melatonin MT2 receptor. It is instrumental in studies aimed at understanding the role of melatonin receptors in circadian rhythms and sleep regulation. By blocking MT2 receptors, it helps elucidate the specific functions and signaling pathways associated with this receptor subtype. This knowledge is crucial for developing targeted therapies for sleep disorders, depression, and other conditions influenced by circadian biology. Additionally, it aids in distinguishing the effects of MT2 receptors from those of MT1 receptors, providing deeper insights into their differential roles in physiological processes.
