Mal-amido-PEG4-C2-acid is a PEG-based PROTAC linker commonly employed in the synthesis of Proteolysis Targeting Chimeras (PROTACs). It consists of a maleimide (Mal) group for selective conjugation with cysteine residues and an amido-PEG4-C2 spacer that imparts flexibility and hydrophilicity to the linker. The amido-PEG4-C2 segment allows for optimal positioning of the target-binding ligand and the protein degrader moiety. By connecting the ligand and the degrader through Mal-amido-PEG4-C2-acid, PROTACs can facilitate the targeted degradation of specific proteins, offering potential therapeutic applications in various diseases.
