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].
Description
Eledoisin’s molecular weight is 1188.4 having an amino acid sequence of Glp-Pro-Ser-Lys-Asp-Ala-Phe-Ile-Gly-Leu-Met-NH2 and a molecular formula of C54H85N13O15S.
Background
Eledoisin is an undecapeptide formed in the venom gland of several species of octopuses and is used as a vasodilator and a contraction agent of extravascular smooth muscle.
