| Hazard Information | Back Directory | [Uses]
Eledoisin (Eledone peptide) is a specific agonist of NK2 and NK3 receptors. | [Definition]
ChEBI: Eledoisin is a peptide. | [in vivo]
Eledoisin (Eledone peptide; 0.1-1 nmol/kg) injected into rats produces a biphasic cardiovascular response that consists of an initial fall of systemic blood pressure (8-15 mm Hg) followed by a rise (20-22 mm Hg). Intracerebroventricular injection of Eledoisin produces an enhancement of grooming and scratching behavior in mice[2]. | [IC 50]
