Mal-PEG-NH-Boc contains a maleimide functional group (-Mal) and a protected amine group (-NH-Boc) attached to the ends of a PEG chain. The maleimide group is known for its ability to selectively react with thiol groups on biomolecules, while the protected amine group can be deprotected under specific conditions, allowing for further functionalization.

Mal-PEG-NH-Boc has been widely used in the development of various drug delivery systems, such as antibody-drug conjugates and protein labeling. Its unique chemical properties allow for the selective and covalent attachment of thiol-containing biomolecules, such as antibodies, enzymes, or peptides, to the PEG chain via the maleimide group. The resulting conjugates exhibit improved stability, enhanced pharmacokinetics, and reduced immunogenicity, leading to increased therapeutic efficacy and reduced side effects.

In addition to its use in drug delivery systems, Mal-PEG-NH-Boc has also been employed as a surface modifier in various biomedical applications. For example, it can be immobilized onto the surface of nanoparticles or medical devices to improve their biocompatibility and reduce immune response.
