Mal-amide-PEG8-Val-Cit-PAB-PNP is a cleavable ADC linker comprising a maleimide group, a PEG spacer, a Val-Cit dipeptide, PAB, and a PNP carbonate. The maleimide serves as a thiol-specific covalent connector for labeling cysteine residues in proteins, whereas the PNP group acts as a highly reactive leaving group. The Val-Cit linker is cleaved by cytoplasmic peptidases.
