A New Class of Antibody–Drug Conjugates with Potent DNA Alkylating Activity

The promise of tumor-selective delivery of cytotoxic agents in the form of antibody–drug conjugates (ADC) has now been realized, evidenced by the approval of two ADCs, both of which incorporate highly cytotoxic tubulin-interacting agents, for cancer therapy. An ongoing challenge remains in identifying potent agents with alternative mechanisms of cell killing that can provide ADCs with high therapeutic indices and favorable tolerability. Here, we...
