Demoxytocin, a heterodetic cyclic peptide, is an analog of oxytocin. Demoxytocin affects the permeability of the cell membrane, increasing the content of calcium ions in smooth muscle cells, increasing its contraction. Demoxytocin also stimulates the contraction of smooth muscles of the uterus. Demoxytocin has the function of oxytocin. Demoxytocin can be used to research stimulation of labor in cases of premature rupture[1].
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.
