| Description | PEG4-bis(phosphonic acid diethyl ester) is a polyethylene glycol (PEG) derivative functioning as a linker in PROTAC synthesis, specifically designed for creating proteolysis-targeting chimeras (PROTACs)[1]. |
| In vitro | PROTACs consist of two distinct ligands linked by a connector: one binds to an E3 ubiquitin ligase, and the other targets a specific protein. They leverage the intracellular ubiquitin-proteasome system to selectively degrade these target proteins[1]. |
