Antisauvagine-30 is primarily used in neuroscience and endocrinology research due to its ability to act as a selective antagonist of the corticotropin-releasing factor (CRF) receptor, particularly the CRF1 subtype. It is employed to investigate the role of CRF in stress-related physiological and behavioral responses. By blocking CRF1 receptors, Antisauvagine-30 helps researchers study the impact of the CRF system on anxiety, depression, and HPA axis regulation. It is often used in animal models to evaluate potential treatments for stress disorders and to dissect the mechanisms underlying neuroendocrine responses. Its selectivity makes it a valuable tool for distinguishing CRF1-mediated effects from those involving other receptor subtypes.
