摘要: The invention pertains to analogs of neurohypophysial hormones evidencing inhibition effects of the chemical formula I ##STR1## where A is CH.sub.3 CO or H, V is a residue of penicilamine or cysteine, B is CH.sub.3 or H, X is a residue of isoleucine or phenylalanine, Y is a residue of penicilamine or cysteine, and Z is a residue of leucine or lysine.These analogues evidence inhibition effects towards certain biological activities of neurohypophysial hormones.

摘要: Vasopressin analogs of the formula ##STR1## wherein R.sup.1 is H, R.sup.2 is CH.sub.2 S and R.sup.3 is D-Arg,R.sup.1 is NH.sub.2, R.sup.2 is S-S and R.sup.3 is D-Arg or L-Orn are described. The described analogs resist enzymatic cleavage while retaining their effect on the central nervous system. These compounds lack a glycinamide residue in the 9 position and have the L-arginine in the 8 position replaced with its stereoisomeric form or with an ornithine residue. The compounds evidence little or no peripheral endocrine effects of natural vasopressin.
