Bradykinin Fragment 1-7 is primarily used in research to study its role in the regulation of blood pressure and inflammation. It helps in understanding the mechanisms of bradykinin-related pathways, particularly its interaction with receptors in the cardiovascular system. This peptide fragment is also utilized in pharmacological studies to develop potential therapeutic agents targeting conditions like hypertension, pain, and inflammatory diseases. Additionally, it serves as a tool in biochemical assays to investigate peptide-receptor interactions and signal transduction processes.
