The present invention relates to linker molecules of formula (1), X-Tb-Va-U-Y-Z (1) and a method for purifying peptides using said linker molecules. The linker molecule can be coupled to a purification resin via the moiety X and to a peptide via the moiety Y under the release of the leaving group Z. T is an optional spacer moiety and V is an optional electron withdrawing moiety. U is an aryl or 5- or 6-membered heteroaryl moiety bound to at least one electron withdrawing moiety V, W or E. The linker is stable under acidic conditions and releases the peptide upon addition of a reducing agent.
本发明涉及式(1)X-Tb-Va-U-Y-Z(1)的连接分子和使用所述连接分子纯化肽的方法。在离去基团 Z 的释放作用下,连接分子可通过分子 X 与纯化
树脂偶联,并通过分子 Y 与肽偶联。U 是一个芳基或 5 或 6 元杂芳基,与至少一个电子逸出基团 V、W 或 E 结合。
