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.

S Ishikawa et al.
Kidney international, 30(1), 49-55 (1986-07-01)
Elevated levels of plasma arginine vasopressin (AVP) have been suggested to impair water excretion in congestive heart failure. In the present study, to determine a role for AVP in the impaired water excretion in rats with the inferior vena cava
S C Mah et al.
Peptides, 9(3), 595-600 (1988-05-01)
The interaction of an antagonist of arginine vasopressin (AVP), d(CH2)5-D-Tyr(Et)VAVP, with renal tubular V2 receptors were studied in medullary membrane preparations from kidneys of Sprague-Dawley and Brattleboro rats. In both rat strains, V2 receptors had comparable KD and Bmax values

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

We investigated the effects of angiotensin II (Ang II), microinjected into the supraoptic (SON) and paraventricular (PVN) nuclei of rats, on the urine outflow rate and underlying mechanisms. Ang II produced antidiuretic effects in a dose-dependent manner with ED50 values
J Filep et al.
The American journal of physiology, 253(5 Pt 2), F952-F958 (1987-11-01)
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.
