Sequence	One Letter Code: XYITNCPXG Three Letter Code: Mpr-D-Tyr(Et)-Ile-Thr-Asn-Cys-Pro-Orn-Gly-NH2
Appearance	Solid powder
Activity	Antagonist
Biological Activity	Potent oxytocin receptor (OTR) antagonist. Inhibits oxytocin-induced increase in Ca2+ concentration in myometrial cells in vitro (IC50 = 5 nM) Activates NF-κB and MAPK pathways in human amnion via Gαi signaling, resulting in pro-inflammatory effects. Inhibits oxytocin-induced uterine contractions in vivo and in vitro. Effective in a rat preterm labor model.
Target	Oxytocin Receptor
