Beschreibung

Application

[Beta-Mercapto-beta,beta-cyclopentamethylenepropionyl¹, O-me-Tyr², Arg⁸]-Vasopressin was used to block Vasopressin (V1a) receptors and study the role of endothelin, vasopressin and angiotensin in regulating arterial pressure during anaesthesia in dogs. The product was used as a test compound for studying the impact of arginine vasopressin and atriopeptin on chloride uptake in cultured Type-I astrocytes.

Biochem/physiol Actions

[Beta-Mercapto-beta,beta-cyclopentamethylenepropionyl¹, O-me-Tyr², Arg⁸]-Vasopressin is a V1a vasopressin receptor antagonist also referred to as “Manning compound”. Vasopressin can stimulate three acid-base transporters and hence increases the capability of the cell to regulate pHi. It induces reversible translocation of aquaporin-CD water channels from intracellular vesicles to apical plasma membrane, which increases the water permeability of collecting duct cells.

Preparation Note

[Beta-Mercapto-beta,beta-cyclopentamethylenepropionyl1, O-me-Tyr2, Arg8] vasopressin dissolves in water at 1 mg/ml to yield a clear, colorless solution.
