BnO-PEG6-OH 是一种不可降解 (non-cleavable) 的含 6 个单元 PEG 的 ADC linker，可用于合成抗体偶联药物 (ADC)。BnO-PEG6-OH 也是一种 PROTAC linker，属于 PEG 类， 可用于合成 PROTAC 分子。
BnO-PEG6-OH is a non-cleavable 6 unit PEG ADC linker used in the synthesis of antibody-drug conjugates (ADCs). BnO-PEG6-OH is also a PEG-based PROTAC linker can be used in the synthesis of PROTACs[1][2].
ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker.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[1].
