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.

To investigate the role of arginine vasopressin (AVP) in the maintenance of blood pressure in deoxycorticosterone (DOC)-salt hypertension, the effects of specific pressor and antidiuretic antagonists of AVP were studied in conscious, freely moving rats with established malignant DOC-salt hypertension.

We report the solid-phase synthesis and some pharmacological properties of 12 position three modified analogues (peptides 1-12) of the potent non-selective antagonist of the antidiuretic (V2-receptor), vasopressor (V1a-receptor) responses to arginine vasopressin (AVP) and of the uterine contracting (OT-receptor) responses
