The subject matter of the present invention is peptide C α -amides which are precursors of peptide C α -thioesters, characterized in that they comprise the radical of general formula (I) in which X, R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , n and A are as defined in Claim 1. The subject matter of the present invention is also the use of these peptide C α -amides for obtaining peptide C α -thioesters. The subject matter of the present invention is also the use of these peptide C α -amides for obtaining peptides or proteins, in particular of therapeutic interest, by direct use as a crypto-thioester partner in NCL reactions. |
