Description
PEG6-(CH2CO2H)2 is a PEG linker containing two terminal carboxylic acid groups. The hydrophilic PEG spacer increases solubility in aqueous media. The terminal carboxylic acids can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond.
Uses
PEG6-(CH2CO2H)2 is a symmetric PEG PROTAC linker, for the synthesis of Homo-PROTACs which is bivalent small-molecule dimerizers of the VHL E3 ubiquitin ligase to induce self-degradation[1].
