Beschreibung

Amino Acid Sequence

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

Anwendung

[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. Wirkung

Potent oxytocin antagonist.

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