Propargyl-Gly(m-PEG4)-Gly-Gly-Phe-Gly-PAB(m-PEG4)-Exatecan pab 309 SMILES CC(C)(C)OC(=O)CCN1CCNCC1 Purity (HPLC)SOLU KNEX cleavable linker features a Gly Gly Phe Gly (GGFG) peptide. In this product, a Propargyl Gly(m PEG4) moiety replaces the conventional maleimidocaproyl (MC) unit to enhance aqueous solubility. The propargyl functional group is widely employed in click chemistry to undergo selective cycloaddition with azides. Additionally, m PEG4 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to further increase aqueous
