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.

Actions biochimiques/physiologiques

[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.

Notes préparatoires

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

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

Valproic acid (VPA) has been used clinically as an anticonvulsant medication during pregnancy; however, it poses a neurodevelopmental risk due to its high teratogenicity. We hypothesized that midgestational (GD) exposure to VPA will lead to lasting deficits in social behavior

Neuroscience, 185, 85-96 (2011-04-05)
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).

Although it is known that moderate-to-high doses of the neurohypophysial hormones oxytocin and vasopressin are natriuretic, doubts remain over the identity of the receptors responsible. To address this issue, we have used highly selective antagonists of oxytocin and vasopressin receptors

The neuropeptide arginine vasotocin (AVT) is well known to modulate both aggression and affiliation, yet few studies relate individual behavioral state to a quantitative assessment of AVT distribution in the brain. Here, using a wild population of beaugregory damselfish, Stegastes
