Abstract

Certain cyclic vasopressin-like peptides, which have an .omega.-amino- or guanidinoalkyl substituent attached to the cysteine in the 6-position of the ring, have vasopressin antagonist activity. A species of this series of new compounds is [1-(.beta.-mercapto-.beta.,.beta.-cyclopentamethylenepropionic acid)-2-(O-ethyl-D-tyrosine)-4-valine-8-(1,5-diaminopentane)-8-desarginine -9-desglycinamide]-vasopressin.
