This peptide is primarily utilized in research settings to study the renin-angiotensin system (RAS), particularly as a selective antagonist of the angiotensin II type 2 receptor (AT2R). It helps in understanding the role of AT2R in various physiological and pathological processes, such as blood pressure regulation, cardiovascular function, and tissue repair. Additionally, it is used to investigate the potential therapeutic effects of AT2R modulation in conditions like hypertension, heart failure, and kidney disease. Its application extends to exploring its effects on cell proliferation, inflammation, and fibrosis, contributing to advancements in drug development targeting the RAS pathway.
