Abstract

Acridines have been used as chemotherapeutic agents against bacteria, protozoa and fungi, and they now find important use as anticancer drugs. There is a paucity of crystal structures of acridine-DNA complexes above the dinucleotide level, but recent structures of acridinecarboxamide topoisomerase II poisons complexed to hexanucleotides have allowed a molecular rationalisation of their structure-activity relationships for cytotoxicity and for their kinetics of DNA binding.

Keywords: acridines, crystal structures, nucleic acids, dna, complexes, acridine-4-carboxamides
