This compound is primarily utilized in the field of targeted drug delivery, particularly in the development of antibody-drug conjugates (ADCs). It serves as a linker-payload system, where the molecule connects a cytotoxic agent to a monoclonal antibody, enabling precise delivery of the drug to cancer cells. The chemical structure includes a polyethylene glycol (PEG) spacer, which enhances solubility and stability, and a cleavable linker that releases the active drug payload upon reaching the target site. Its application is significant in oncology, as it helps minimize off-target effects and improve therapeutic efficacy. Additionally, the compound is used in proteolysis-targeting chimeras (PROTACs) for targeted protein degradation, offering potential in treating diseases caused by aberrant protein expression.
