Nortopixantrone, also known as BBR-3438, is a DNA topoisomerase inhibitor potentially for thetreatment of gastric cancer, ovarian cancer. BR 3438 exhibited a unique profile of preclinical activity with a superior efficacy against prostatic carcinoma models compared to reference compounds (doxorubicin and losoxantrone). The antitumour efficacy of BBR 3438 against prostatic carcinoma could be the result of a combination of favourable events, including enhanced intracellular accumulation and an increased DNA-binding affinity favouring the accumulation of multiple sublethal or lethal damage.
