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 CH.sub.2 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.
公开了化学式I H--Tyr--D--Lys(For)--Gly--X(I)的新肽酰胺,其中For为甲酰基,X为烷基氨基,脱氢苯丙氨基或苯丙氨基取代物,取代物在烷基部分中最多有6个碳原子,该部分可以被羟基和/或苯基取代,环烷基酰胺或环烷基亚烷基酰胺,其环烷基或环烷基亚烷基部分中最多有8个碳原子,1到2个CH.sub.2基团可以被--NH--,--O--,--S--或--CO--取代,Phe-烷基-环烷基酰胺,其环中有5至6个碳原子,该酰胺可以被碳酰胺基,N-烷基碳酰胺基或烷基取代,其中1个碳原子可以被氮原子取代,Phe-内-或外-去氢萘基酰胺或Phe-噻唑酰胺或Phe-噻唑烷羧酸酰胺,其可以被1到4个甲基基团取代,以及其制备方法。这些肽酰胺具有镇痛活性并抑制豚鼠回肠的运动性。
