An agent that inhibits Topoisomerase II and intercalates with a DNA hexanucleotide, causing DNA damage and inhibition of DNA replication, RNA and protein synthesis.

A tricyclic acridine-based (or carboxamide-based) drug with dual topoisomerase inhibitor and potential antineoplastic activities. Acridine carboxamide inhibits both topoisomerases I and II and intercalates into DNA, resulting in DNA damage, the disruption of DNA repair and replication, the inhibition of RNA and protein synthesis, and cell death.
