Amino Acid Sequence

(1-Mercaptocyclohexyl)acetyl-Tyr(O-Ethyl)-Phe-Val-Asn-Cys-Pro-Arg-Gly-NH2 [Disulfide Bridge: 1-6]

Application

[Beta-Mercapto-beta, beta-cyclopentamethylenepropionyl1, O-Et-Tyr2, Val4, Arg8]-Vasopressin is a potent V1a and V2 vasopressin receptor anatgonist, used for examining the impact of vasopressin V1receptor blockade in rats.The product was also be used for visualizing cell surface V1a receptors in rat hepatocytes by using high-affinity fluorescent linear antagonist, Rhm8 -PVA.

Biochem/physiol Actions

Vasopressin also known as antidiuretic hormone (ADH) or argipressin can stimulate three acid-base transporters and hence increases the capability of the cell to regulate pHi.ADH can induce reversible translocation of aquaporin-CD water channels from intracellular vesicles to apical plasma membrane, which in turn increases the water permeability of collecting duct cells.

Water diuresis was produced in rats after s.c. injections of d(CH2)5,D-Ile2,Ile4-AVP (compound 1) and d(CH2)5,Tyr(OEt)2Val4-AVP (compound 2). Compound 1 is known to be a more potent antagonist against the antidiuretic effect, while Compound 2 is a more potent antagonist against

We examined the hypothesis that V2-like receptors might contribute to the hemodynamic response seen after blockade of the vasoconstrictor (V1) effect of arginine vasopressin (AVP) in nonhypotensive hemorrhage. Seven chronically instrumented dogs were bled 15 ml/kg within 15 min on
