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.

During suckling, the periodic and synchronous bursting activity of oxytocin neurons has been shown to be facilitated by oxytocin itself, acting via several target sites, including the magnocellular nuclei. To investigate the role of the endogenous oxytocin released within the

Oxytocin (OT) is a peptide involved in several physiological functions in the central nervous system including central cardiovascular regulation. To clarify the role of endogenous OT in cardiovascular control, one group of anesthetized rats received unilateral microinjections of the OT

Sodium chloride ingestion is stimulated during conditions of sodium deficiency to maintain body fluid and electrolyte balance. Recent studies have indicated that salt appetite in rats is often inversely related to peripheral and central secretion of the hormone oxytocin (OT).

The neuropeptide oxytocin (20-100 ng), induces penile erection when injected unilaterally into the caudal but not rostral mesencephalic ventral tegmental area (VTA) of male Sprague-Dawley rats. Such pro-erectile effect started 30 min after treatment and was abolished by the prior
