A novel amidation strategy using electrophilic sulfonium, which is soluble and stable in aqueous conditions, was developed. The sulfoniums could activate thioacid and carboxyl acid to efficiently react with amines to afford amides. This method enables applications in amidation in both aqueous media and solid-phase peptide synthesis, peptide/protein modifications, and reactive lysines of a proteome
开发了一种使用亲电锍的新型酰胺化策略,该锍在水性条件下可溶且稳定。锍可以活化硫代酸和羧酸,有效地与胺反应生成酰胺。该方法可用于水介质和固相肽合成中的酰胺化、肽/蛋白质修饰以及在 pH 10 的蛋白质组的反应性赖氨酸以及基于活性的蛋白质分析。还使用这种方法对 USP7-UBL2 结构域进行了肽配体定向标记。
