Mal-Propionyl-Dap(m-PEG4)-Val-Cit-PAB(m-PEG8)-MMAE exatecan 9 SMILES ClCCOCCOCCOCC(=O)NC1=C2CN(C3CCC(=O)NC3=O)C(=O)C2=CC=C1 Purity (HPLC)SOLU KNEX cleavable linker features a Val Cit dipeptide. In this product, a Mal Propionyl Dap(m PEG4) moiety replaces the conventional maleimidocaproyl (MC) unit to enhance aqueous solubility. The Mal Propionyl group may also improve retro Michael addition stability during antibody conjugation. Additionally, m PEG8 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to further increase aqueous solubility. The payload is
