Detailed Information
| Item | Description |
|---|---|
| Structure | Consists of a PEG chain with two ethylene oxide units, an amino group (NH2) at one end, and a tosylate (Tos) group at the other end |
| Reactivity | The amino group can react with carboxyl groups to form amide bonds, with aldehydes to form Schiff bases, or with other activated groups. The tosylate group is a good leaving group for nucleophilic substitution reactions |
| Applications | – PROTAC Synthesis: Used as a linker in the synthesis of Proteolysis-Targeting Chimeras (PROTACs) for selective protein degradation.<br>- Bioconjugation: Modifies proteins, peptides, and other biomolecules to improve stability and reduce immunogenicity.<br>- Drug Delivery: Enhances drug stability and targeting.<br>- Surface Modification: Improves biocompatibility of nanoparticles and other materials.<br>- Material Science: Used in the synthesis of functional coatings and polymers. |
| Advantages | High biocompatibility, good water solubility, and versatile reactivity. The PEG chain enhances stability and reduces immunogenicity |
