Mal-Propionyl-PEG6-Val-Ala-PAB(m-PEG4)-MMAE ggfg 68 SMILES CC1=C(SC=N1)C1=CC=C(CNC(=O)[C@@H]2C[C@@H](O)CN2C(=O)[C@@H](NC(=O)CCCC#C)C(C)(C)C)C=C1 Purity (HPLC)SOLU KNEX cleavable linker features a Val Ala dipeptide. The conventional maleimidocaproyl (MC) unit is replaced by Mal Propionyl PEG6 moiety to enhance aqueous solubility. The Mal Propionyl group may also improve retro Michael addition stability during antibody conjugation. m PEG4 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to increase aqueous solubility. The payload is monomethyl auristatin E (MMAE), a highly
