We have confirmed that doxorubicin induces irreversible changes in the nucleolar ultrastructure of myocardial cells of rats. Similar changes were not caused by an equal dose of the synthetic analogue, 5-iminodaunomycin. These results combined with previous and current comparative tests with this analogue, doxorubicin, and daunomycin suggest that 5-iminodaunomycin may serve as a less cardiotoxic anthracycline derivative.
