A prodrug in which a peptide is covalently conjugated with the anthracycline antineoplastic antibiotic doxorubicin. This complex is hydrolyzed by the enzyme prostate-specific antigen (PSA), resulting in the formation of doxorubicin and leucine-doxorubicin. Selective targeting of these drugs to prostate tumor cells occurs because the hydrolyzing PSA enzyme is localized to the prostate gland. Doxorubicin and leucine-doxorubicin intercalate into DNA and interacts with topoisomerase II, thereby inhibiting DNA replication and repair and RNA and protein synthesis. These agents also produce toxic free-radical intermediates and interact with cell membrane lipids causing lipid peroxidation. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
