WAY-337530 is primarily used in scientific research as a potent and selective agonist for the 5-HT2C receptor, a subtype of serotonin receptor. Its main application lies in neuroscience and pharmacology studies, where it helps investigate the role of 5-HT2C receptor activation in regulating behaviors such as feeding, mood, and reward processing. Due to its selectivity, it is valuable in experiments aiming to differentiate 5-HT2C effects from those mediated by closely related receptors like 5-HT2A or 5-HT2B. It has been explored in preclinical models for potential therapeutic applications in obesity and substance use disorders, where modulation of serotonin pathways plays a critical role. However, it remains a research compound and is not used clinically.
