title: Tumorigenic potential of endoperoxide analogs.
abstract: The endoperoxide analogs known as U-46619 and U-44069 significantly enhanced the carcinoma formation and cellular atypicality initiated by a chemical carcinogen in mice. Studies of DNA radioactivity demonstrated that endoperoxides exerted their cocarcinogenic action by stimulating DNA synthesis. Thus, they play an important role in tumor cell proliferation.
