[Des-Arg9]-Bradykinin acetate is primarily used in research settings to study the role of bradykinin receptors, particularly the B1 receptor subtype. It serves as a selective agonist for the B1 receptor, making it valuable in understanding inflammatory processes, pain mechanisms, and vascular responses. This compound is often employed in pharmacological studies to investigate receptor signaling pathways and to develop potential therapeutic agents targeting inflammation and pain. Additionally, it is utilized in experimental models to explore conditions such as sepsis, arthritis, and other inflammatory diseases. Its application extends to in vitro and in vivo studies aimed at elucidating the physiological and pathological roles of the B1 receptor in various tissues and systems.
