vasopressin

Vasopressin (argipressin), a cyclic nine-peptide synthesized by hypothalamic neurons, is one of the hormones involved in peptide prohormone synthesis. Vasopressin is involved in the regulation process of hypothalamic-pituitary-adrenal axis, increasing the amount of solute free water reabsorbed from the renal tubule's colate back into the circulation, narrowing arteries to increase pressure, enhancing the stimulating effect of corticotropin releasing factor to regulate pituitary corticotropin secretion. Vasopressin acts as a neurotransmitter during nerve conduction by binding to specific G-protein-coupled receptors.

Vasopressin acetate, a cyclic nonapeptide, is synthesized centrally in the hypothalamus. Vasopressin acetate acts as a neurotransmitter, exerting its action by binding to specific G protein-coupled receptors.

Dp[Tyr(Me)2,Arg8]-Vasopressin is a non-selective antagonist of the peptide arginine vasopressin V1b receptor [1].

Vasopressin Dimer (parallel) TFA, a parallel dimer of Vasopressin, has the capability to activate four G protein-coupled receptors—namely, V1aR, V1bR, V2R, and OTR [1].

Vasopressin Dimer (anti-parallel) TFA, an anti-parallel dimer form of vasopressin, has the capability to activate four G protein-coupled receptors: V1aR, V1bR, V2R, and OTR [1].

[Deamino-Pen1,Val4,D-Arg8]-vasopressin (AVP-A) is an antagonist of arginine-vasopressin (AVP) that effectively reduces plasma aldosterone concentration in rats and is used to study the growth and steroidogenic capacity of the rat adrenal zona glomerulosa [1].

Selective vasopressin V1A receptor antagonist. Inhibits vasopressin and oxytocin-induced increases in intracellular calcium concentrations in vitro (IC50 values are 5 and 30 nM respectively). Exhibits potent and prolonged antivasopressor activity and indu

LIT-001 improves social interaction in a mouse model of autism.It is the first nonpeptide oxytocin receptor agonist with EC50 of 55 nM and Ki of 226 nM.

Atosiban (RW22164) is an inhibitor of the hormones oxytocin and vasopressin. It is used as an intravenous medication as a labour repressant (tocolytic) to halt premature labor. Atosiban inhibits the oxytocin-mediated release of inositol trisphosphate from the myometrial cell membrane. 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. In human pre-term labor, atosiban, at the recommended dosage, antagonizes 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.
