Alkyne-PEG3-COOH is a bifunctional triethyleneglycol derivative bearing a carboxy group, and an alkyne moiety. The former can be activated with peptide coupling reagents like PyBOP or carbodiimides like EDC to form a stable amide linkage with amines. The alkyne group can be coupled with azides in a CuAAc reaction.

PEGs are hydrophilic linkers that are useful in the synthesis of water soluble conjugates.

Alkyne-PEG3-COOH 是一种带有羧基和炔烃部分的双功能三甘醇衍生物。 前者可以用肽偶联试剂(如 PyBOP)或碳二亚胺(如 EDC)活化,与胺形成稳定的酰胺键。 炔基可以在 CuAAc 反应中与叠氮化物偶联。
