Polypeptides, a process for their preparation, their use, and a process for the purification of polypeptides

摘要

Polypeptides of the formula I V-X-D-Trp-Y-D-Trp-Leu-Z-NH2 wherein V represents a naturally occurring aminoacid or a physiologically acceptable acid radical, X represents a naturally occurring aminoacid or a single bond, Y represents one of the aminoacids, Phe, Ile, Val, Tyr and L-p-Cl-Phe, and Z represents the aminoacids Met or Nle, and salts thereof, in particular pharmaceutically acceptable salts thereof, a process for the preparation of these polypeptides and pharmaceutical products which contain these compounds. The invention also relates to a process for the purification of polypeptides by column chromatography.
