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.

In freshly isolated rat hepatocyte multiplets, Ca2+ signals in response to vasopressin are highly organized. In this study we used specific probes to visualize, by fluorescence and confocal microscopy, the main signaling molecules involved in vasopressin-mediated Ca2+ responses. V1a receptors

Synthetic oxytocin and vasopressin agonists and antagonists have become important tools for research and were instrumental in the identification of the four known receptor subtypes, V1a, V2, V1b (V3) and oxytocin, of these peptide hormones. However, the relative lack of

To visualize cell surface V1a vasopressin receptors in rat hepatocytes in the absence of receptor-mediated endocytosis, we used a high-affinity fluorescent linear antagonist, Rhm8-PVA. Epifluorescence microscopy (3CCD camera) and fluorescence spectroscopy were used. Rhm8-PVA alone did not stimulate Ca2+ signals

The present study was undertaken to determine whether a non-peptide arginine vasopressin (AVP) antagonist [5-dimethylamino-1-(4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetra hydro-1H- benzazepine] (OPC-31260) improves the impaired water excretion in rats with experimental liver cirrhosis. Male Wistar rats weighing 200 to 250 g were injected in

We report the solid-phase synthesis of the D-Cys6 analogues of arginine-vasopressin (AVP), peptide 1, of the selective AVP vasopressor (V1a receptor) antagonist [1-(beta-mercapto-beta,beta-pentamethylenepropionic acid),2-O-methyltyrosine]arginine-vasopressin (d(CH2)5[Tyr(Me)2]-AVP, (A)), peptide 2, of the three nonselective antidiuretic/vasopressor (V2/V1a receptor) AVP antagonists d(CH2)5[Tyr(Et)2]VAVP (B), d(CH2)5[D-Tyr(Et)2]VAVP
