Amino Acid Sequence

β-Mercapto-β,β-Cyclopentamethylenepropionyl-MeTyr-Ile-Gln-Asn-Cys-Pro-Orn-Gly-NH2 [Disulfide Bridge: 1-6]

应用

[β-Mercapto-β,β-cyclopentamethylenepropionyl1, O-Me-Tyr2, Orn8]-Oxytocin has been used as an oxytocin receptor antagonist:
  • to study the influence of blockading the oxytocin receptors in the anterior cingulate cortex on helping behavior
  • to determine the receptors that mediate vasopressin-stimulated anion secretion across cultured porcine vas deferens epithelial cell monolayers
  • to study the influence of oxytocin receptors inhibition on intravenous and in situ oxytocin effects on the urinary bladder and cardiovascular activities in sham rats

生化/生理作用

Potent oxytocin antagonist.
[β-Mercapto-β,β-cyclopentamethylenepropionyl1, O-Me-Tyr2, Orn8]-also acts as an arginine vasopressin receptor 1A (AVPR1A) antagonist.

In order to provide further support for a role of central nitric oxide as a mediator of penile erection and yawning, the nitric oxide donors sodium nitroprusside, hydroxylamine, isoamyl nitrite and S-nitroso-N-acetyl-penicillamine were injected into the lateral ventricles (i.c.v.) or

The effect of three oxytocin receptor antagonists on the renal actions of oxytocin and vasopressin was investigated in conscious male rats infused with hypotonic saline. Infusion of oxytocin at 100 pg/min produced plasma concentrations of 12.7 +/- 3.3 pmol/l and

Oxytocin facilitates social recognition in rats and mice, onset of maternal behavior in virgin mice and formation of pair bonds without copulation in prairie voles. However, the relationship between this peptide and paternal behavior in primates remains largely unknown. We

Female rats with maternal experience display a shorter onset of maternal responsiveness compared to those with no prior experience. This phenomenon called 'maternal memory' is critically dependent on the nucleus accumbens (NA) shell. We hypothesized that activation of OT receptors
