Zusammenfassung:To provide a novel method of enzymatically synthesizing GLP-1 or an analogue thereof, in particular Liraglutide or Semaglutide.SOLUTION: The invention relates to a method for synthesizing 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 nucleophile 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, where 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 functionalized with an amino acid or another functional group; Z is Arg or Lys.SELECTED DRAWING: None 【課題】GLP-1又はその類似体、特にリラグルチド又はセマグルチドを酵素的に合成する新規の方法を提供すること。【解決手段】本発明は、(a)配列His-X-Glu-Gly-Thr-Phe-Thr-Ser-Asp-Val-Ser-(チオ)エステルを含む第1のペプチド断片を含むペプチドC末端エステル又はチオエステルと、(b)配列H-Ser-Tyr-Leu-Glu-Gly-Gln-Ala-Ala-Y-Glu-Phe-Ile-Ala-Trp-Leu-Val-Z-Gly-Arg-Glyを含む第2のペプチド断片を含むN末端非保護アミンを有するペプチド求核剤とを酵素的にカップリングさせることを含む、配列His-X-Glu-Gly-Thr-Phe-Thr-Ser-Asp-Val-Ser-Ser-Tyr-Leu-Glu-Gly-Gln-Ala-Ala-Y-Glu-Phe-Ile-Ala-Trp-Leu-Val-Z-Gly-Arg-Glyを含むペプチドを合成するための方法に関し、ここで、XはAla又はα-アミノ-イソ酪酸(Aib)残基であり、YはLysであり、このLysは遊離側鎖ε-アミノ基を有するか、或いはLysの側鎖ε-アミノ基は保護基によって保護されているか、或いはLysの側鎖ε-アミノ基はアミノ酸又は別の官能基によって官能化されており、ZはArg又はLysである。【選択図】なし
