Abstract
Vasopressin derivatives having V.sub.1 and oxytocin antagonist activity whose structures are characterized by a Mpa unit at position 1 and a des-Pro unit at position 7 are prepared by standard peptide synthetic methods also using an oxidative cyclization of a dimercaptan. Representative species are [1-deaminopenicillamine-2-(O-methyl)-tyrosine-7-desproline-8-arginine-9-de sglycine]vasopressin or [1-.beta.-mercaptopropionic acid-2-D-(O-ethyl)tyrosine-3-isoleucine-4-threonine-7-desproline-8-arginin e-9-desglycine]-vasopressin.
