Mal-Propionyl-PEG4-Gly-Gly-Phe-Gly-PAB(m-PEG4)-PNP acid 92 SMILES O=C(CCCC[C@@H]1SC[C@@H]2NC(=O)N[C@H]12)NCCOCCOCCOCCOCCC(=O)NCCC(=O)N1CC2=CC=CC=C2C#CC2=CC=CC=C12 Purity (HPLC)SOLU KNEX cleavable linker features a Gly Gly Phe Gly (GGFG) peptide. The conventional maleimidocaproyl (MC) unit is replaced by Mal Propionyl PEG4 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 PNP (para nitrophenyl) moiety serves as an
