improved efficiency. N-Phenyl-N-aceto-vinylsulfonamide exhibits higher reactivity and has emerged as an efficient reagent that has the ability to realize the selective modification of peptides and proteins at the N-terminus via aza-Michael addition. We showed that, after conjugation of peptides and proteins with the reagent containing a bioorthogonal functional group, the derivatives could be further
合成并筛选了许多乙烯基磺酰胺,以鉴定可用于在生物 pH 值和室温下以更高的效率修饰奥曲肽的试剂。N-Phenyl-N-aceto-vinylsulfonamide 表现出更高的反应性,并已成为一种有效的试剂,能够通过 aza-Michael 加成在 N 端实现肽和蛋白质的选择性修饰。我们表明,在肽和蛋白质与含有生物正交官能团的试剂缀合后,衍生物可以通过功能进一步标记,包括荧光标签、修饰药物和聚乙二醇 (PEG) 聚合物,而无需事先处理。生长抑素、溶菌酶和 RNaseA 在 N 端进行了选择性修饰,说明了该方法的应用。
