Amino Acid Sequence

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

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.

Arginine-vasopressin (AVP) is critical for the expression of a variety of social behaviors in many species. Previous studies have demonstrated that AVP regulates behaviors such as social communication and aggression in Syrian hamsters through the V1a receptor subtype. In male

The nonapeptides arginine vasopressin (AVP; including its non-mammalian homolog arginine vasotocin, AVT) and oxytocin (OT; including its non-mammalian homologs mesotocin, MT, and isotocin, IT) regulate social behavior, including aggression and reproduction, via receptors conserved across vertebrates.

The neuropeptide arginine vasopressin (AVP) modulates a variety of species-specific social behaviors. In socially monogamous male prairie voles, AVP acts centrally via vasopressin V1a receptor (V1aR) to facilitate mating induced partner preferences. The display of a partner preference requires at

Ion and water homeostasis in the CNS is subjected to a neuroendocrine control exerted by neuropeptides formed within the brain. In order to gain information on this neuroendocrine control of Cl- homeostasis, 36Cl- uptake was measured in cultured Type-I astrocytes

In the latero-anterior hypothalamus (LAH) increased glutamate and vasopressin (AVP) activity facilitate anabolic androgenic steroid (AAS)-induced offensive aggression. In addition, adolescent AAS treatment increases the strength of glutamate-mediated connections between the LAH and the brain nucleus of stria terminalis (BNST).
