NCIt definition : The hydrochloride salt of a third-generation synthetic 9-amino-anthracycline with
antineoplastic activity. Amrubicin intercalates into DNA and inhibits the activity
of topoisomerase II, resulting in inhibition of DNA replication, and RNA and protein
synthesis, followed by cell growth inhibition and cell death. This agent has demonstrated
a higher level of anti-tumor activity than conventional anthracycline drugs without
exhibiting any indication of the cumulative cardiac toxicity common to this class
of compounds.;
