Quaternaryprotoberberinealkaloids and quaternary benzophenanthridine alkaloids are two biosynthetically related natural product families of biological importance. Although significant advances have been achieved in the synthetic chemistry of these alkaloids, a unified approach to these tetracyclic pyridinium-contained alkaloids remains elusive until our recent report. Herein, we report a concise

(EN) The present invention provides protoberberine alkaloid derivatives useful as anticancer agents, and methods of use thereof. The invention also provides protoberberine derivatives useful as topoisomerase inhibitors. The invention further provides coralyne and nitidine derivatives which are topoisomerase I-targeted therapeutics effective against camptothecin resistant cancer cells, and are especially effective against CNS tumors.(FR) L'invention concerne des dérivés d'alcaloïde de protoberbérine utiles en tant qu'agents anti-cancer, ainsi que leurs procédés d'utilisation. Elle concerne également des dérivés de protoberbérine utiles en tant qu'inhibiteurs de topoisomérase. Elle concerne encore des dérivés de coralyne et de nitidine qui sont des agents thérapeutiques dirigés contre la topoisomérase I et efficaces contre les cellules cancéreuses résistant à la camptothécine, ainsi que, particulièrement, contre les tumeurs du système nerveux central.

inium chloride was the most potent topoisomerase I poison among the coralyne analogues evaluated, having similar activity to camptothecin. This analogue also possessed exceptional potency as a topoisomeraseII poison. Despite the pronounced activity of several of these coralyne derivatives as topoisomerase I poisons, none of these compounds had cytotoxicactivity similar to camptothecin. Possible differences
