compound introduction
N-(acid-PEG3)-N-bis(PEG3-azide) 是一种 PROTAC linker，属于 PEG 类。可用于合成 PROTAC 分子。N-(acid-PEG3)-N-bis(PEG3-azide) 是一种点击化学试剂。它含有 Azide 基团，可以和含有 Alkyne 基团的分子发生铜催化的叠氮-炔环加成反应（CuAAc)。还可以和含有 DBCO 或 BCN 基团的分子发生菌株促进的炔-叠氮环加成反应 (SPAAC)。 N-(acid-PEG3)-N-bis(PEG3-azide) is a branched PEG derivative with azide moieties and a terminal carboxylic acid. The azide groups enable PEGylation via Click Chemistry. The terminal carboxylic acid can be reacted with primary amine groups in the presence of activators (e.g. EDC, or DCC) to form a stable amide bond. The hydrophilic PEG linker increases the solubility of the compound in aqueous media.
