Biological Activity
Endogenous bradykinin receptor agonist that displays some selectivity for the B2 receptor (Ki values are 2.54 and 0.63 nM at human B1 and B2 receptors respectively). Hypotensive agent that reduces peripheral vascular resistance in vivo. Twice as potent as bradykinin (Cat No. 3004) in vivo.
