[Production and antitumor properties of carminazone]

Karminazon (13-benzoylhydrazon) was prepared by condensation of karminomycin with benzoylhydrazine. In its intravenous use in the treatment of mice with lymphosarcoma L10-1 karminazon was less toxic and had lower antitumor activity than karminomycin. Karminazon had a lower selective antitumor activity with respect to lymphosarcoma than karminomycin.
