生物活性

Oxytocin free acid (9-Deamidooxytocin) is an analog of oxytocin in which the glycinamide residue at position 9 in oxytocin has been replaced by a glycine residue. Oxytocin is a pleiotropic, peptide hormone with broad implications for general health, adaptation, development, reproduction, and social behavior[1][2].

Cell Assay
[1]

Single halved pituitary glands of female CFE rats weighing 100 to 150 g are preincubated for two hours in Krebs-Ringer-bicarbonate-glucose (2%) medium under 5% CO2 in O2, and then for one hour periods each with 300 ng. lysine vasopressin and the sample of vasopressin ring peptide Pressinoic Acid. The incubations are separated by a one hour ish period. The media from the pituitary incubations are added to rat adrenal quarters superfused for estimation of the steroidogenic response to the corticotrophin released. The steroidogenie effect of the unstimulated release of corticotrophin by the pituitary tissue and the possible steroidogenic effect of the peptide directly on the adrenal tissue are measured together by adding the peptide to the media from pituitary tissue incubated without peptide for one hour[1].
