Medchemexpress LLC Thiol-PEG6-alcohol | 194425-46-2 | ≥97.0% | 50 MG
Thiol-PEG6-alcohol is a PEG-based PROTAC linker used in the synthesis of PROTACs. PROTACs are molecules containing two different ligands connected by a linker, where one ligand targets an E3 ubiquitin ligase and the other targets a specific protein. They function by exploiting the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
- PEG-based PROTAC linker
- Used in the synthesis of PROTACs
- Leverages the intracellular ubiquitin-proteasome system
- Selectively degrades target proteins
