rubitecan 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 active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
