    摘要: Certain vasopressin-like peptides, which have an acyclic unit at position 1 and which have an .omega.-amino- or guanidinoalkyl substituent attached to the cysteine in the 6-position of the ring, have V.sub.1 -vasopressin and oxytocin antagonist activity. A species of this series of new compounds is [1-desaminopenicillamine-2-(O-ethyl-D-tyrosine)-8-(1,4-diaminobutane)-9-desglycinamide]-vasopressin.

    摘要: 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.
