Banoxantrone (AQ4N) is a novel and potent bio-reductive prodrug that can be reduced under hypoxic conditions (hypoxia-activated) to a stable, DNA-affinic compound AQ4 (CAS#: 70476-63-0), which is a potent topoisomerase II inhibitor with anticanceractivity. Banoxantrone intercalates into and crosslinks DNA, and inhibits topoisomerase II. This results in an inhibition of DNA replication and repair in tumor cells. Combined with conventional therapeutic agents, both oxygenic and hypoxic regions of tumors can be targeted.
| ln Vitro |
Tumor radiofrequency caused by benoxintrone (20 μM; 90 min) results in hypoxic T50/80 cell destruction [1].

|---|---|
| ln Vivo |
Banoxantrone (200 mg/kg; intraperitoneal injection; single dosage) causes cell damage in BDF mice and greatly suppresses T50/80 tumors [1].

| ADME/Pharmacokinetics |
Metabolism / Metabolites
AQ4N is selectively and irreversibly converted to AQ4, its cytotoxic form, in hypoxic tumor cells, which are its targeted site of action. Biological Half-Life 0.64 to 0.83 hours |

| Additional Infomation |
Banoxantrone is a highly selective bioreductive drug that is activated in, and is preferentially toxic to, hypoxic cells in tumours. It has been shown to work synergistically with fractionated radiation to significantly delay growth of tumours compared to administration of either banoxantrone or radiation alone. Banoxantrone was also efficacious in tumour models when administered in combination with either cisplatin or chemoradiation.
Banoxantrone is a bioreductive, alkylaminoanthraquinone prodrug with antineoplastic activity. Under hypoxic conditions, often seen in solid tumors, banoxantrone (AQ4N) is converted and activated by cytochrome P450 enzymes, which are upregulated in certain tumors, to the cytotoxic DNA-binding agent AQ4. Banoxantrone intercalates into and crosslinks DNA, and inhibits topoisomerase II. This results in an inhibition of DNA replication and repair in tumor cells. Combined with conventional therapeutic agents, both oxygenic and hypoxic regions of tumors can be targeted. Drug Indication For the treatment of various forms of cancer. Mechanism of Action Banoxantrone (formally known as AQ4N) is preferentially and irreversibly converted to AQ4, its cytotoxic form, in hypoxic tumour cells where it remains localised. When the surrounding oxygenated cells are killed by radiotherapy or chemotherapy bringing these AQ4-containing quiescent cells closer to the oxygen source, they become reoxygenated, attempt to resume replication and, in this state, are killed by AQ4 through potent DNA intercalation and topoisomerase II inhibition. Pharmacodynamics AQ4N was rationally designed to have anti-tumor activity following bioreduction by tissue cytochrome P450 to AQ4, an active DNA topoisomerase II inhibitor. Preclinical studies demonstrated AQ4N selectively targets lymphoid tissues and hypoxic tumor tissues. |
