WAY-607987 is primarily used in scientific research as a selective agonist for the 5-HT2C receptor, making it a valuable tool for studying serotonin signaling pathways in the central nervous system. It has been employed in preclinical studies to investigate the role of 5-HT2C receptors in regulating appetite, mood, and impulse control, which may have implications for developing treatments for obesity, depression, and addiction. Due to its selectivity, it helps researchers differentiate the effects of 5-HT2C activation from those of other serotonin receptor subtypes. Its use is currently restricted to laboratory and experimental settings, with no approved clinical applications in humans.
