Used in targeted cancer therapies, particularly in the development of antibody-drug conjugates (ADCs). It serves as a linker-payload, enabling the delivery of cytotoxic agents directly to cancer cells while minimizing damage to healthy tissues. This compound is especially valuable in treating multiple myeloma and other hematologic malignancies. Its structure allows for controlled release of the active drug, enhancing therapeutic efficacy and reducing side effects. Additionally, it is utilized in research to study drug delivery mechanisms and improve the precision of cancer treatments.
