叠氮基-PEG3-酸是基于PEG 的 PROTAC linker,可用于合成BI-3663 、BI-4216 和 BI-0319。N3-PEG3-CH2CH2COOH 同时也是一种不可降解 (non-cleavable) 的含 3 个单元 PEG 的 ADC linker,可用于合成抗体偶联活性分子 (ADC)。N3-PEG3-CH2CH2COOH 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)。 Azido-PEG3-acid is a PEG derivative containing an azide group with a terminal carboxylic acid. The terminal carboxylic acid can be reacted with primary amine groups in the presence of activators (e.g. EDC, or DCC) forming a stable amide bond. The azide group enables Click Chemistry. The hydrophilic PEG spacer increases solubility in aqueous media.
