Novel polypeptides having thymic activity or an antagonistic activity and processes for their synthesis

Abstract

The invention is concerned with novel polypeptides and processes for the synthesis thereof. It is concerned with compounds having the sequence X-Gln-Gly-Gly-Y in which Y represents -Ser-Asn and X represents Ser-, Lys-Ser-, Ala-Lys-Ser-, Glx-Ala-Lys-Ser-; Glx representing Pyro-Glu or Gln; and when X represents Glx-Ala-Lys-Ser-, Y may in addition represent -Ser; as well as their derivatives comprising one or two modified amino acids, with the exception of the unmodified compound PyroGlu-Ala-Lys-Ser-Gln-Gly-Ser-Asn. These polypeptides are useful as medicines.
