The invention discloses a method for the preparation of a peptide by liquid phase coupling of two fragments, an N-terminal fragment and a C-terminal fragment of the desired peptide, wherein the C-terminal fragment is protected on its C-terminal COOH by a psWang linker; the method is demonstrated with liraglutide wherein the C-terminal fragment carries the Palmitoyl-Glu-OtBu residue on the Lys(20).
本发明公开了一种通过液相偶联所需
多肽的两个片段(N-端片段和C-端片段)来制备
多肽的方法,其中C-端片段的C-端COOH受psWang连接体的保护;该方法用
利拉鲁肽进行了验证,其中C-端片段的Lys(20)上带有棕榈酰-Glu-OtBu残基。
