The mechanism of action on RNA synthesis of anticancer dibromo-dulcitol (DBD, NSC-104800) and dianhydro-dulcitol (DAD, or elsewhere dianhydrogalactitol, DAG, NSC-132313) was investigated. Rats, bearing Yoshida or Novikoff hepatoma ascites tumor cells sensitive to these drugs were treated with doses
A ribonuclease was isolated from serum-free supernatants of the human colon adenocarcinoma cell line HT-29. It was purified by cation-exchange and C18 reversed-phase high-performance liquid chromatography. The protein is basic, has a molecular weight of approximately 16,000, and has an amino acid
Mitomycin C, an antitumor antibiotic, is rapidly metabolized in the presence of rat liver microsomes. NADPH and anaerobic conditions are required for the process. The products isolated after reexposure to air are 2,7-diaminomitosene derivatives. Specifically, in the presence of inorganic phosphate,
