Mechanism of action

Doxorubicin is an anthracycline chemotherapy agent that inserts itself between DNA base pairs (intercalation) and blocks topoisomerase II, an enzyme essential for DNA unwinding and repair. This dual mechanism leads to DNA strand breaks, inhibition of DNA synthesis, and ultimately cancer cell death. It is also believed to generate reactive oxygen species that contribute to its cytotoxic effects.
