Bis-propargyl-PEG13 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.
structure and hydrogen bonding
Bis-propargyl-PEG13 comprises two propargyl groups which can form triazole linkages with azide-bearing compounds or biomolecules in copper catalyzed Click Chemistry reactions. The hydrophilic PEG units help improve the solubility of the molecule in aqueous media.
