Abstract

Peptides having vasopressin antagonist activity are prepared by a peptide synthesizer to insert a N-methylarginine at the 7-position of the structure. An example of this series of compounds is [1-(.beta.-mercapto-.beta.,.beta.-cyclopentamethylenepropionic acid)-2-(O-ethyl-D-tyrosine)-4-valine-7-desproline-8-N-methylarginine-9-de sglycine]-vasopressin.
