5-Iminodaunorubicin. Reduced cardiotoxic properties in an antitumor anthracycline

Abstract
Treatment of daunorubicin with methanolic ammonia affords 5-iminodaunorubicin, the 1st quinone-modified analog of daunorubicin or adriamycin. This product retains antileukemic activity in mice [P-388 leukemia cells], is less cardiotoxic by electrocardiographic measurements in rats and is nonmutagenic in Salmonella typhimurium (Ames test).
