[Obtaining 14-oxycarminomycin and a study of its antitumor activity]

The authors obtained 14-oxykarminomycin by alkaline hydrolysis of 14-bromokarminomycin. On two-fold intravenous administration to mice with lymphosarcoma, strain L10-1, 14-oxycarminomycin showed the same toxicity as karminomycin. The preparation had the same selective antitumor activity as karminomycin.
