[Uses]

[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

[Biochem/physiol Actions]

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