Lys-(Des-Arg9, Leu8)-Bradykinin is a bradykinin B1 receptor antagonist (Ki = 0.43 nM for the rabbit aorta receptor).1 It is selective for the bradykinin B1 over the B2 receptor (Ki = >10 µM for the rabbit ileum receptor).2 Lys-(Des-Arg9, Leu8)-Bradykinin inhibits contractions induced by the bradykinin B1 receptor agonist Des-Arg9-bradykinin in isolated rabbit aortic rings (pA2 = 8.54).3 Intraperitoneal administration of Lys-(Des-Arg9, Leu8)-bradykinin (5 mg/kg per day for three days) reduces increases in paw edema in a rat model of arthritis induced by peptidoglycan-polysaccharide (PGPS).4
