NH2-PEG5-C6-Cl hydrochloride is a PEG-based PROTAC linker that 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.
- PEG-based PROTAC linker
- Used in the synthesis of PROTACs
- Contains two different ligands connected by a linker
- Exploits the intracellular ubiquitin-proteasome system
- Selectively degrades target proteins
- Applicable in cancer and cancer targeted therapy research
- Classified as PROTAC linkers

Bromoacetamido-PEG3-C2-Boc is a PEG-based PROTAC linker that is utilized in the synthesis of PROTACs. PROTACs themselves are small molecules composed of two different ligands connected by a linker; one ligand targets an E3 ubiquitin ligase, and the other targets a protein of interest. This mechanism allows PROTACs to leverage the intracellular ubiquitin-proteasome system for the selective degradation of target proteins.
- Application: used in the synthesis of PROTACs.
- Mechanism: facilitates the degradation of target proteins via the ubiquitin-proteasome system when incorporated into PROTACs.
- Research use: for research purposes only; not intended for sale to patients.
- Form: liquid (density: 1.252 g/cm3), colorless to light yellow.

N-(Azido-PEG3)-N-bis(PEG4-acid) is a PEG-based PROTAC linker designed for use in the synthesis of PROTACs. This compound acts as a click chemistry reagent, featuring an Azide group. It can participate in copper-catalyzed azide-alkyne cycloaddition (CuAAc) reactions when combined with Alkyne groups. Additionally, it is capable of undergoing strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.
