Daunomycin is an anthracycline antibiotic produced by Streptomyces peucetius. The mechanism of action is the same as that of doxorubicin, which is inserted into DNA and inhibits RNA and DNA synthesis. It is mainly used for the treatment of acute myeloid and lymphocytic leukemia, with adverse reactions such as cardiotoxicity and bone marrow suppression. It has anti-gram-positive bacteria, negative bacteria and tumor activity.
