aq4

AQ4 is a topoisomerase II inhibitor and DNA-inserting agent that displays antitumor activity in CRC cell lines.

Banoxantrone D12 (AQ4N D12) dihydrochloride is the deuterium-labeled Banoxantrone. Banoxantrone is a bioreductive agent that can be reduced to a stable, DNA-affinity compound AQ4, which is a topoisomerase II inhibitor.

Banoxantrone D12 (AQ4N D12) is the deuterium-labeled form of Banoxantrone, a bioreductive agent that can be metabolically converted to AQ4, a stable compound with DNA affinity and topoisomerase II inhibition properties.

Banoxantrone (AQ4N), a hypoxia-selective cytotoxin prototype, undergoes reduction to AQ4, effectively inhibiting topoisomerase II. It selectively targets and eradicates hypoxic cells through an iNOS-dependent mechanism. This compound demonstrates significant cytotoxicity with its hypoxia-selective action being augmented by radiation.
