[Mechanisms of the antitumor action of spirobromine in mice with leukemia P-388].
The influence of new antitumor drug, spirobromine, a derivative of dispirotripiperazine, on DNA synthesis in tumor cells and organs at different times after its injection into mice with P388 leukemia has been studied. The duration of DNA synthesis inhibition in tumor cells was found to correlate with spirobromine antitumor activity. A certain selectivity of action of the studied compound on DNA synthesis in P 388 leukemia cells as compared to the action on DNA synthesis in bone marrow, small intestine, spleen and liver of tumor animals was observed.
