The present study was undertaken to compare the antileukemic potential of epidoxorubicin and its two formamidine analogs containing either a morpholine moiety (EPIFmor) or a hexamethyleneimine moiety (EPIFhex) in the amidine group. Materials and Methods: The experiments were performed in vitro on MOLT-4 cells using spectrophotometry, Coulter electrical impedance, flow cytometry, and light microscopy methods. Results: The leukemia cell responses to the action of the anthracyclines were manifested in their different viability, count and volume, degree of apoptosis and necrosis, activity of caspases -8, -9, and -3/7, mitochondrial membrane potential, and in the cell-cycle distribution. In general, epidoxorubicin appeared to be the most active, and EPIFmor was more active than EPIFhex against MOLT-4 cells. Conclusion: The structural modifications of epidoxorubicin in the amidine group were responsible for the varied action of its formamidine analogs on human acute lymphoblastic leukemia cells.
