Used in research for its potent vasoactive and smooth muscle-contracting properties. Shows activity in cardiovascular studies due to its ability to modulate blood pressure and vascular tone. Investigated for potential use in understanding kinin receptor interactions and inflammatory pathways. Also applied in pharmacological assays to evaluate peptide stability and bioavailability, especially in models involving neuropeptides and signaling molecules. Its trifluoroacetate salt form enhances solubility for in vitro and in vivo testing.
