摘要
The relationship between the structure of new semisynthetic derivatives of doxorubicin, daunorubicin, and carminomycin and their ability to inhibit topoisomerase I were studied. The new derivatives inhibit the activity of topoisomerase I at low concentrations, induce the death of K-562 leukemia cells in culture, and produce an antitumor effect in experimental animals bearing P388 leukemia.
