Storage: Long-term: -20°C (sealed, desiccated); Short-term: Room temperature for up to 3 weeks; Reconstituted: 4°C for 2–7 days (avoid repeated freeze-thaw cycles)
Grade: Research Grade / Pharmaceutical Reference Standard (For laboratory use only; not for clinical use)
Atosiban is a synthetic nonapeptide analog of oxytocin and a potent, selective competitive antagonist of both oxytocin receptors (OTR) and vasopressin V1a receptors (V1aR)PMC. Developed by Ferring , it is widely recognized as a first-line tocolytic agent for delaying preterm labor in clinical settings, with well-characterized safety and efficacy profiles. As a research tool, it enables precise investigation of oxytocin/vasopressin signaling pathways, uterine contractility, and preterm birth mechanisms.
  • High Purity & Consistency: Manufactured via solid-phase peptide synthesis (SPPS) with rigorous RP-HPLC purification; batch-to-batch consistency validated by COA, MS, and amino acid analysis.
  • Dual Receptor Antagonism: Potently blocks OTR and V1aR, inhibiting oxytocin-induced uterine contractions and prostaglandin release (PGE/PGF) from the deciduaPMC.
  • Rapid Onset & Reversibility: Intravenous administration achieves rapid uterine quiescence (contractions reduced within 10 minutes) with minimal fetal/maternal cardiovascular effectsPMC.
  • Stable Formulation: Lyophilized powder format preserves stability; no additional excipients, ensuring reliable reconstitution and experimental reproducibility.
  • Versatile Applications: Suitable for reproductive biology, pharmacology, and development research; ideal for in vitro/in vivo studies of preterm labor and uterine function.
Atosiban competes with oxytocin for binding to OTR (a GPCR) on myometrial cells, blocking Gαq-PLC-Ca²⁺ signaling cascadesPMC. This reduces intracellular calcium release from the sarcoplasmic reticulum and inhibits calcium influx through voltage-gated channels, suppressing uterine contractionsPMC. It also antagonizes V1aR, further reducing oxytocin-mediated prostaglandin production and uterine sensitivity to oxytocinPMC.

Applications

  • Reproductive Biology Research: In vitro studies of myometrial contractility, oxytocin/vasopressin signaling, and preterm birth pathogenesis; in vivo animal models for evaluating tocolytic efficacy.
  • Pharmacology & Development: Lead compound for developing novel tocolytic agents; reference standard for OTR/V1aR binding assays and pharmacokinetic studies.
  • Biomedical Research: Investigation of uterine inflammation, prostaglandin metabolism, and calcium signaling in reproductive tissues.
