Synthesis of a heterotrifunctional linker for the site-specific preparation of antibody-drug conjugates with two distinct warheads

Codelivery of multiple therapeutic agents with different anticancer mechanisms can overcome drug resistance as well as generate additive or synergistic anticancer effects that may enhance the antitumor efficacy. Antibody-drug conjugates (ADCs) can be used for highly specific delivery of multiple therapeutic agents with different anticancer mechanisms, though more research is required towards designing flexible platforms on which dual drug ADCs...
