Daunorubicin (Daunomycin) citrate, a potent anti-tumor anthracycline antibiotic, acts as a topoisomerase II inhibitor. It effectively inhibits DNA and RNA synthesis, diminishes cancer cell viability, and promotes apoptosis and necrosis. This cytotoxic compound is utilized in researching a range of cancers, such as leukemia, non-Hodgkin lymphomas, Ewing's sarcoma, and Wilms' tumor, as well as infections [1] [2] [4] [5].
