Azido-PEG4-CH2-Boc 是一种可降解 (cleavable) 的含 4 个单元 PEG 的 ADC linker，可用于合成抗体偶联活性分子 (ADC)。Azido-PEG4-CH2-Boc 也是一种 PROTAC linker，属于 PEG 和 Alkyl/ether 类，可用于合成 PROTAC 分子。Azido-PEG4-CH2-Boc 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-PEG4-CH2-Boc is a cleavable 4 unit PEG ADC linker used in the synthesis of antibody-drug conjugates (ADCs). Azido-PEG4-CH2-Boc is also a PEG- and Alkyl/ether-based PROTAC linker that can be used in the synthesis of PROTACs. Azido-PEG4-CH2-Boc is a click chemistry reagent, itcontains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. Strain-promoted alkyne-azide cycloaddition (SPAAC) can also occur with molecules containing DBCO or BCN groups.
