peptides containing two cysteines are described. These scaffolds contain a functionality with orthogonal reactivity to be used for labeling and ligation. This is illustrated by the chemical ligation of two dissimilar constrained peptides via oxime ligation or strain-promoted azide–alkyne cycloaddition in aqueous media.
描述了构象约束含有两个半胱氨酸的侧链未保护的线性肽的水溶性支架的合成和应用。这些支架包含具有正交反应性的功能,可用于标记和连接。这可以通过在水性介质中通过肟连接或应变促进的叠氮化物-炔烃环加成反应将两种不同的受约束肽进行化学连接来说明。
