Used as a potent antagonist for the neuropeptide Y (NPY) Y1 receptor in research settings, enabling studies on NPY-related physiological processes such as appetite regulation, anxiety, and cardiovascular function. It is commonly employed in in vitro and in vivo experiments to block Y1 receptor activity, helping to elucidate the role of this receptor in various biological systems. Due to its high selectivity and affinity, it serves as a valuable tool compound in neuroscience and pharmacology research, particularly in investigations related to feeding behavior, stress responses, and potential therapeutic targets for obesity and mood disorders.
