ABSTRACT:
Compounds acting as antagonists of the antidiuretic activity of arginine vasopressin are those of the formula ##STR1## wherein X is methyl, ethyl, n-propyl, isopropyl or butyl; Tyr is D- or L-; W is Pro or .DELTA..sup.3 -Pro; and Z is L- or D- Arg. Related compounds in which X is H, methyl or ethyl; W is Pro and Val at the 4-position is replaced by Gln- have antivasopressor activity against arginine vasopressin. Compounds wherein D-Tyr is unetherified (X is H), W- is Pro and Z- is D- or L-Arg also act as antagonists of the antidiuretic activity of arginine vasopressin.
