New peptide amides of the formula I H-Tyr-D-Lys(For)-Gly-X (I) wherein For is formyl, X is alkylamino, dehydro-Phe or Phe-alkylamido having up to 6 carbon atoms in the alkyl moiety, which moiety may be substituted by hydroxy and/or phenyl, Phe-cycloalkylamide or Phe-cycloalkylene amide having up to 8 carbon atoms in the cycloalkyl or cyclalkylene moiety, 1 to 2 CH2 groups being optionally replaced by -NH-, -O-, -S- or -CO-, Phe-alkylene-cycloalkylamide having from 5 to 6 ring carbon atoms, which amide may be substituted by carbonamido,N-alkylcarbonamido or alkyl and 1 carbon atom whereof may be replaced by nitrogen, Phe-endo- or exo-norbornylamide or Phe-thiazolamide or Phe-thiazolidine-carboxylic acid amide, which may be substituted by 1 to 4 methyl groups each, and process for their manufacture are disclosed. These peptide amides are distinguished by an analgetic activity and suppress the motility of the ileum of the guinea pig. |
