Mal-amido-PEG10-acid is a PEG-based linker for PROTACs which joins two essential ligands, crucial for forming PROTAC molecules. This linker enables selective protein degradation by leveraging the ubiquitin-proteasome system within cells.
(S,R,S)-AHPC-C2-PEG4-N3 (VH032-C2-PEG4-N3) is a synthesized E3 ligase ligand-linker conjugate combining the (S,R,S)-AHPC-based VHL ligand with a 4-unit polyethylene glycol (PEG) linker, employed in PROteolysis TAgeting Chimera (PROTAC) technology. This compound facilitates the creation of vRucaparib-TP4, a potent PARP1 degrader demonstrating a half-maximal degrading concentration (DC50) of 82 nM[1].
