Used primarily in scientific research as a potent and selective antagonist for the neuropeptide Y (NPY) Y1 receptor. It helps investigate the role of NPY in various physiological processes such as appetite regulation, anxiety, cardiovascular function, and circadian rhythms. Due to its high selectivity, it is valuable in studies aiming to differentiate Y1 receptor activity from other NPY receptor subtypes. Commonly applied in neuropharmacology and behavioral studies, especially in animal models, to explore links between NPY signaling and conditions like obesity, hypertension, and stress-related disorders. Not intended for clinical or therapeutic use in humans.
