Novel polypeptides, processes for their production, pharmaceutical compositions comprising said polypeptides and their use

摘要

Straight-chain and mono-cyclic polypeptides containing the basic sequence wherein X is an amino acid residue, the residues in the 1- and 6-positions being linked by an -S-S- bridge when the polypeptide is monocyclic, have pharmacological, in particular GH-, gastric- and pancreatic-secretion inhibiting activity.
