用途: Atosiban(RW22164; Tractocile) is a nonapeptide, desamino-oxytocin analogue, and a competitive vasopressin/oxytocin receptor antagonist (VOTra). Atosiban inhibits the oxytocin-mediated release of inositol trisphosphate from the myometrial cell membrane.IC50 value:Target: As a result, there is reduced release of intracellular, stored calcium from the sarcoplasmic reticulum of myometrial cells, and reduced influx of Ca2+ from the extracellular space through voltage gated channels. In addition, atosiban suppresses oxytocin-mediated release of PGE and PGF from the decidua.[1][2] In human pre-term labour, atosiban, at the recommended dosage, antagonises uterine contractions and induces uterine quiescence. The onset of uterus relaxation following atosiban is rapid, uterine contractions being significantly reduced within 10 minutes to achieve stable uterine quiescence. 物理化学性质: CAS号:90779-69-4 常用中文名:阿托西班 常用英文名:(Deamino-Cys1,D-Tyr(Et)2,Thr4,Orn8)-Oxytocin acetate salt 分子式:C43H67N11O12S2 分子量:994.189 密度:1.3±0.1 g/cm3 沸点:1469.0±65.0 °C at 760 mmHg 熔点:N/A 闪点:842.2±34.3 °C 储存条件:−20°C |
