Bombinakinin M

This small molecule is a highly potent and selective agonist for mammalian arterial smooth muscle bradykinin receptors, demonstrating approximately 50 times the potency of bradykinin. It induces dose-dependent contraction in guinea pig ileum smooth muscle (EC50 = 4.0 nM), making it a valuable tool for investigating bradykinin receptor function in vascular pharmacology and smooth muscle physiology research.
