Bis-Tos-PEG4 是一种属于 PEG 类的 PROTAC linker，可用于 PROTAC 分子的合成。

Bis-Tos-PEG4 (PROTAC Linker 16) is a PEG-based PROTAC linker. Bis-Tos-PEG4 can be used in the synthesis of PROTACs.

PROTACs contain two different ligands connected by a linker; one of them is a ligand for an E3 ubiquitin ligase and the other one is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins[1].
