building block for Fmoc/tBu solid phase peptide synthesis (SPPS) of β-linked O-GlcNAcylated peptides. This building block carries acid labile silyl ether protecting groups, which are fully removed under TFA-mediated peptide cleavage conditions from the resin, thus requiring fewer synthetic steps and no intermediate purification as compared to other acid or base labile protecting group strategies.
在本报告中,我们介绍了一种用于 β-连接O -GlcNA 酰化肽的 Fmoc/ t Bu 固相肽合成 (SPPS) 的新型构建模块。该结构单元带有酸不稳定的甲硅烷基醚保护基,在 TFA 介导的肽裂解条件下从树脂中完全去除,因此与其他酸或碱不稳定的保护基策略相比,需要更少的合成步骤,并且无需中间纯化。
