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."}]
