    Abstract: The invention provides a method of making a peptide comprising the amino acid sequence WDLYFEIVW (SEQ ID NO: 322) or a variant thereof, the method comprising (a) coupling the C-terminal amino acid of the peptide to a cleavable linking moiety bonded to a solid phase support material, wherein the alpha-amino group of the C-terminal amino acid that is to be coupled bears an Fmoc protecting group; (b) removing the Fmoc protecting group from the C-terminal amino acid that is coupled to the linking moiety; (c) successively coupling Fmoc-protected amino acids to the C-terminal amino acid, with attendant cleavage of the Fmoc protecting group prior to each successive amino acid addition, thereby producing an amino acid sequence bearing side chain protecting groups; and (d) removing the side chain protecting groups and cleaving the peptide from the solid phase support material.

    Abstract translation: 本发明提供了制备包含氨基酸序列WDLYFEIVW(SEQ ID NO:322)或其变体的肽的方法,所述方法包括(a)将肽的C-末端氨基酸与可键合到 固相载体材料,其中待偶联的C端氨基酸的α-氨基具有Fmoc保护基; (b)从与所述连接部分偶联的C末端氨基酸中除去Fmoc保护基团; (c)连续将Fmoc保护的氨基酸偶联至C-末端氨基酸,并在每次连续的氨基酸加入之前伴随着Fmoc保护基裂解,由此产生带有侧链保护基团的氨基酸序列; 和(d)除去侧链保护基团并从固相载体材料中切割肽。
