CHEMO-ENZYMATIC SYNTHESIS OF SEMAGLUTIDE, LIRAGLUTIDE AND GLP-1

The invention relates to a method for synthesising a peptide comprising the sequence His-X-Glu-Gly-Thr-Phe-Thr-Ser-Asp-Val-Ser-Ser-Tyr-Leu-Glu-Gly-Gln-Ala-Ala-Y-Glu-Phe-lle-Ala-Trp-Leu-Val-Z-Gly-Arg-Gly, comprising enzymatically coupling (a) a peptide C-terminal ester or thioester comprising a first...

Zusammenfassung:	The invention relates to a method for synthesising a peptide comprising the sequence His-X-Glu-Gly-Thr-Phe-Thr-Ser-Asp-Val-Ser-Ser-Tyr-Leu-Glu-Gly-Gln-Ala-Ala-Y-Glu-Phe-lle-Ala-Trp-Leu-Val-Z-Gly-Arg-Gly, comprising enzymatically coupling (a) a peptide C-terminal ester or thioester comprising a first peptide fragment comprising the sequence His-X- Glu-Gly-Thr-Phe-Thr-Ser-Asp-Val-Ser-(thio)ester; and (b) a peptide nudeophile having an N-terminally unprotected amine comprising a second peptide fragment comprising the sequence H-Ser-Tyr-Leu-Glu-Gly-Gln-Ala -Ala-Y-Glu-Phe-lle-Ala-Trp-Leu-Val-Z- Gly-Arg-Gly wherein - X is Ala or an α-amino-isobutyric acid (Aib) residue - Y is Lys, which Lys has a free side-chain ε-amino group or of which Lys the side-chain ε-amino group is protected with a protective group or of which Lys the side-chain ε-amino group is functionalised with an amino acid or another functional group - Z is Arg or Lys.
