Bradykinin (1-6) is primarily used in research settings to study its role in inflammation, blood pressure regulation, and pain pathways. It serves as a truncated form of the full bradykinin peptide, allowing scientists to investigate the specific functions of its amino acid sequence. This compound is often utilized in pharmacological studies to understand receptor interactions and signaling mechanisms, particularly in relation to bradykinin receptors (B1 and B2). Additionally, it aids in the development of therapeutic agents targeting conditions like hypertension, chronic pain, and inflammatory diseases. Its application also extends to exploring its effects on vascular permeability and smooth muscle contraction.
