Claim 1
Independent Claim
93 words
A peptide of the general formula ##STR5##wherein X represents Ser(Bu t ), Cys(Bu t ), Asp(OBu t ), Glu (OBu t ), Orn(Boc) or Lys(Boc) and Y is glycinamide or a NH-alkyl group wherein the alkyl radical contains 1 to 3 carbon atoms and may be substituted by OH groups or halogen atoms, or Y is the NH-cyclopropyl radical and wherein Trp may be substituted by pentamethylphenyl alanine, Ser by Ala or Thr, Tyr by Phe, Gly by D-amino acids corresponding to the naturally occuring L-amino acids, Arg by Orn, Lys or homoarginine.
