Application: D-Arg-[Hyp³,Thi⁵,⁸,D-Phe⁷]-Bradykinin is a potent synthetic antagonist of the bradykinin B2 receptor. Incorporation of D-amino acids and thioether substitutions enhances receptor selectivity and resistance to enzymatic degradation. By selectively inhibiting B2 receptor-mediated signaling, this peptide is widely used to investigate bradykinin effects in vascular tone regulation, inflammation, edema, pain signaling, and cardiovascular physiology. It serves as a valuable pharmacological tool for differentiating B2-dependent pathways from inducible B1 receptor responses and for studying kinin receptor function in acute inflammatory and vascular disease models.
