专利号:US-2023391818-A1 优先权日:2020-11-05 标 题:Peptide synthesis method for suppressing defect caused by diketopiperazine formation 发明人:NOMURA KENICHI; KAGE MIRAI; TAMIYA MINORU; KANAZAWA JUNICHIRO 权利人:CHUGAI PHARMACEUTICAL CO LTD 摘要:Solid-phase synthesis of a peptide has a problem that a desired elongation reaction is prevented from proceeding by diketopiperazine and a 6-membered diamine skeleton compound formed when a protective group at the N-terminal is removed. The present inventors have found that when in production of a peptide by a solid-phase method, a peptide in which an amino group at the N-terminal is protected with a protective group having an Fmoc skeleton is treated in a specific solvent with a base having a pKa of 23 or more in acetonitrile as a conjugate acid, and a peptide chain is then elongated, it is possible to solve the problem described above.

The inventors have discovered that it is possible to solve said problem during peptide production by treating a peptide protected by an N-terminated amino group in a protective group having an Fmoc skeleton by using a base which has a pKa of 23 or higher in an acetonitrile of a conjugate acid in a specific solvent, and next, performing peptide chain elongation.
