This compound is primarily utilized in targeted drug delivery systems, particularly in the field of cancer therapy. It serves as a linker molecule that connects cytotoxic drugs to antibodies or other targeting agents. The structure allows for the controlled release of the drug at the tumor site, minimizing damage to healthy tissues. It is often employed in antibody-drug conjugates (ADCs), where it ensures the drug remains stable in circulation but is cleaved upon reaching the target cancer cells. This enhances the precision and efficacy of the treatment while reducing systemic toxicity.
