Description

Amino Acid Sequence

Mpa-Tyr-Phe-Val-Asn-Cys-Pro-Arg-Gly-NH2

Application

[Deamino-Cys1, Val4, D-Arg8]-Vasopressin was used to prepare sample for qualitative detection of desmopressin in plasma by using liquid chromatography-electrospray tandem mass spectrometry.

Biochem/physiol Actions

[Deamino-Pen1, O-Me-Tyr2, Arg8]-Vasopressin is a V1 antagonist that stabilizes the cardiocirculatory function in normal human as well as in patients suffering from catecholamine-resistant vasodilatory shock.It can also stimulate three acid-base transporters and hence increases the capability of the cell to regulate pHi.

Preparation Note

[deamino-Cys1, Val4, D-Arg8]-Vasopressin dissolves in water at 1 mg/ml to yield a clear, colorless solution.
