carubicin and Carcinoma--Bronchogenic

The antiblastomic activity of the carminomycin complex components was studied with respect to 8 strains of transplantable tumors of mice: lymphosarcoma L10-1, prestomach cancer OZh-5, sarcoma 180, lymphoid leucosis L 1210, lung bronchogenic cancer RL, lymphodenosis NK/LI, Ehrlich carcinoma and Garding-Passy melanoma. It was shown that components I, II and III possessed almost the same high antiblastomic activity and the same optimal administration schemes should be used for them. The scheme consisted of two-fold administration of the drug at intervals of 96-120 hours. Component I had broader therapeutic ranges and was more active against the lung bronchogenic cancer as compared to component II. All 3 components had no selective antiblastomic effect on the ascitic form of Ehrlich carcinoma. A comparative study of the component toxicity and pharmacology is required for final conclusion as to the recommendation of one of the components for clinical trials.
