Ms-PEG-Ms is a chemical compound that belongs to the class of polyethylene glycol (PEG) derivatives. This compound contains two mesyl functional groups (-SO3CH3) attached to the ends of a PEG chain, offering unique opportunities for the design of novel drug delivery systems.

Ms-PEG-Ms is highly reactive towards nucleophiles, such as amines or thiol groups, due to the presence of the mesyl groups. This reactivity can be utilized to covalently link the PEG chain to various bioactive molecules, such as drugs, peptides, and proteins. The resulting conjugates exhibit improved pharmacokinetics, increased stability, and reduced immunogenicity, making them attractive candidates for drug development.

One of the most promising applications of mesyl-PEG-mesyl is in the field of antibody-drug conjugates (ADCs). ADCs are innovative therapeutics that combine the selectivity of monoclonal antibodies with the potency of small molecule drugs. Mesyl-PEG-mesyl can be used to link the PEG chain to the antibody, while the mesyl groups can react with the drug molecule, resulting in a stable and highly specific conjugate.
