Abstract
Abstract The invention relates to polypeptides of the formula I ##STR1## in which m denotes 0-50, n denotes 0-100 and R denotes the phenolic hydrogen or a phenol ester group, X represents identical or different residues of naturally occurring α-amino acids, Y denotes Val, Ile, Thr, Leu or Phe, and Z represents identical or different residues of naturally occurring α-amino acids, and in which the Cys residues are linked pairwise via disulfide bridges, to a process for preparing or obtaining them and to agents containing them.

Claim 2
Dependent Claim
54 words
A polypeptide of the formula I ##STR4## wherein R denotes the phenolic hydrogen or a phenol ester group, and Y denotes Val, Ile, Thr, Leu or Phe, and in which the six Cys residues at positions 5, 13, 15, 21, 27 and 38 are linked pairwise via disulfide bridges, and its physiologically tolerated salts.
Claim 3
Dependent Claim
18 words
