Antibody–drug conjugates: Recent advances in linker chemistry

Antibody-drug conjugates (ADCs) are gradually revolutionizing clinical cancer therapy. The antibody-drug conjugate linker molecule determines both the efficacy and the adverse effects, and so has a major influence on the fate of ADCs. An ideal linker should be stable in the circulatory system and release the cytotoxic payload specifically in the tumor. However, existing linkers often release payloads nonspecifically and inevitably lead to...
