Mal-Propionyl-PEG6-Gly-Gly-Phe-Gly-PAB(m-PEG4)-Exatecan m-peg4-pab Product Name DOTA-tris(t-Bu)ester-C2-propanamido-maleimide Synonyms CASSOLU KNEX cleavable linker features a Gly Gly Phe Gly (GGFG) peptide. 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 Exatecan, a highly potent
