Val-Cit-PAB-OH is a peptide cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs). The Val-Cit will specifically be cleaved by Cathepsin B.

Val-cit-PAB-OH acts as a reagent in the preparation of cell-penetrating peptidic GRP78 ligand for tumor cell-specific prodrug therapy, preparation of monomethylvaline derivative conjugates with ligands and antibodies for cancer treatment.
