Abstract: A KISS1R agonist peptide compound capable of inducing ovulation in a female mammal is provided. The compound is a pseudopeptide having the C-terminal sequence: -Xaa?[Tz]Xaa2-Xaa3-Xaa4-NH2 (SEQ ID NO: 3), where ?[Tz] represents a 1,4-disubstituted 1,2,3-triazole group replacing the peptide bond between the Xaa1 residue and the Xaa2 residue, Xaa1 is Gly or Ala, Xaa2 is Leu or an aliphatic ?-aminoacyl analog residue, Xaa3 is Arg, Arg(Me) or a positively charged ?-aminoacyl analog residue, and Xaa4 is Tyr, Phe, Trp or an ?-aminoacyl analog residue such as aryl alanine; or an analog of the pseudopeptide in which the amide peptide bond between Xaa2 and Xaa3 and/or between Xaa3 and Xaa4 is replaced with an isosteric bond, or a salt thereof.

Abstract: The subject matter of the present invention is peptide C?-amides which are precursors of peptide C?-thioesters, characterized in that they comprise the radical of general formula (I) in which X, R1, R2, R3, R4, R5, R6, R7, R8, R9, n and A are as defined in Claim 1. The subject matter of the present invention is also the use of these peptide C?-amides for obtaining peptide C?-thioesters. The subject matter of the present invention is also the use of these peptide C?-amides for obtaining peptides or proteins, in particular of therapeutic interest, by direct use as a crypto-thioester partner in NCL reactions.
