Mal-Lys(m-PEG4)-Val-Cit-PAB(m-PEG4)-Exatecan Size:25mg 473 SMILES O=C1N(CC2=C(NCCOCCOCCOCC#C)C=CC=C12)C1CCC(=O)NC1=O Purity (HPLC)SOLU KNEX cleavable linker features a Val Cit dipeptide. In this product, a Mal Lys(m PEG4) moiety replaces the conventional maleimidocaproyl (MC) unit to enhance aqueous solubility. Additionally, m PEG4 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to further increase aqueous solubility. The payload is Exatecan, a highly potent topoisomerase I inhibitor derived from camptothecin, which induces DNA damage by
