[Antitumor activity of carminomycin antibiotic used orally]

Antitumor activity of karminomycin used perorally was studied with respect to 3 strains of mouse transplantable tumors, i. e. one ascitic strain of lymphadenosis NK/LI and two solid strains of lymphosarcoma L10-1 and sarcoma 180. Karminomycin was shown to have a high antitumor activity against the above tumors on its oral administration. In the experiments with lymphadenosis NK/LI the efficiency of karminomycin was higher when it was used perorally as compared to its intravenous administration. It was found that karminomycin had practically the same inhibitory effect on growth of lymphosarcoma L10-1 and sarcoma 180 on its peroral and intravenous administration in doses equivalent by their toxicity.
