WAY-273170 is primarily used in neuroscience research as a potent and selective agonist for the ghrelin receptor (Growth Hormone Secretagogue Receptor, GHS-R1a). Its main application lies in studying appetite regulation, energy homeostasis, and metabolic functions. Researchers utilize WAY-273170 to investigate the role of the ghrelin signaling pathway in food intake and body weight control, making it a valuable tool in obesity and eating disorder studies. Additionally, it has been employed to explore cognitive functions and mood-related behaviors, as ghrelin receptors are present in brain regions linked to memory and stress response. Due to its selectivity, it helps isolate receptor-specific effects without significant off-target activity, supporting clean pharmacological profiling in preclinical models.
