Mal-Lys(m-PEG4)-Gly-Gly-Phe-Gly-PAB(m-PEG4)-MMAE nitrogen 64 SMILES CC1=C(SC=N1)C1=CC=C(CNC(=O)[C@@H]2C[C@@H](O)CN2C(=O)[C@@H](NC(=O)COCC(O)=O)C(C)(C)C)C=C1 Purity (HPLC)SOLU KNEX cleavable linker features a Gly Gly Phe Gly (GGFG) peptide. 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 monomethyl auristatin E (MMAE), a highly potent antimitotic agent that inhibits tubulin polymerization,
