Banoxantrone dihydrochloride (AQ4N dihydrochloride) is an oxygen-depleted activated topoisomerase II inhibitor, AQ4N binds to DNA in a non-covalent manner and promotes antitumor activity of hypoxic and hypoxic tumor cells[1-4].
AQ4N(0-0.25 mM;24h) showed 8-fold higher cytotoxicity under hypoxia than normoxia in cultures of 9L rat gliosarcoma and H460 human non-small-cell lung carcinoma cells[5].
AQ4N(200 mg/kg; i.p.; 30 minutes before radiation) was combined with radiation, considerable DNA damage was detected in T50/80 tumors implanted in BDF mice after immediate excision[2,6].Activation of AQ4N cytotoxicity in mice requires extensive and prolonged tumor hypoxia[5]. AQ4N inhibited HMEC-1 cell contacts on Matrigel, HMEC-1 cell invasion, and sprouting in rat aorta explants. When AQ4N (20 mg/kg) was given in vivo for 5 days, microvessels disappeared in LNCaP tumors grown in a dorsal skin flap[7].
