A semisynthetic agent related to camptothecin with potent antitumor and antiviral properties. Rubitecan binds to and inhibits the enzyme topoisomerase I and induces protein-linked DNA single-strand breaks, thereby blocking DNA and RNA synthesis in dividing cells; this agent also prevents repair of reversible single-strand DNA breaks. Check for \'https://www.cancer.gov/about-cancer/treatment/clinical-trials/intervention/C1485\' active clinical trials using this agent.
