Bombesin acetate salt hydrate is widely used in biomedical research due to its role as a neuropeptide that interacts with G-protein-coupled receptors. It is particularly valuable in studies focused on understanding the regulation of appetite, gastrointestinal motility, and the release of gastrin and other hormones. Researchers utilize it to investigate its effects on cancer cell proliferation, as bombesin receptors are often overexpressed in certain tumors, such as those in the prostate, breast, and lung. Additionally, it serves as a tool in neuropharmacology to explore its involvement in stress responses and behavioral regulation. Its applications extend to experimental models for studying peptide-receptor interactions and developing targeted therapies for receptor-associated diseases.
