Tetraethylene glycol (compound 28) 是一种 PROTAC linker,属于 PEG 类。Tetraethylene glycol 可用于合成一系列 PROTAC 分子。
Br-PEG3-CH2COOH (compound 28) is a PEG-based PROTAC linker can be used in the synthesis of PROTACs.
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.
