Azido-PEG8-NHS ester 是一种可降解 (cleavable) 的含 8 个单元 PEG 的 ADC linker，可用于合成抗体偶联药物 (ADC)。Azido-PEG8-NHS ester 也是一种 PROTAC linker，属于 PEG 和 Alkyl/ether 类，可用于合成 PROTAC 分子。
Azido-PEG8-NHS ester is a cleavable 8 unit PEG ADC linker used in the synthesis of antibody-drug conjugates (ADCs)[1]. Azido-PEG8-NHS ester is also a PEG- and Alkyl/ether-based PROTAC linker that can be used in the synthesis of PROTACs[2].
ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker[1].PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins[2].
