[EN] NOVEL ARTEMISININ-LIKE DERIVATIVES WITH CYTOTOXIC AND ANTI-ANGIOGENIC PROPERTIES [FR] NOUVEAUX DÉRIVÉS DE TYPE ARTÉMISININE POSSÉDANT DES PROPRIÉTÉS CYTOTOXIQUES ET ANTIANGIOGÈNES
corresponding C-16 allylic bromides 5 and 7. Both glycals 2 and 3 react with NBS to provide compounds 5 and 7, respectively. From the 10-CF3 anhydrodihydroartemisinin 3, the allylicbromination also occurred in high yield with Br2 in CCl4. Products 5 and 7 react with N-, O- and C-nucleophiles. From 5, products of SN and SN′ were obtained in low to moderate yield, while the CF3-substituted allylic bromide 7
探索了脱水二氢青蒿素2及其10-三氟甲基类似物3对溴化试剂的反应性,目的是制备新的相应的C-16烯丙基溴5和7。二醇2和3均与NBS反应,分别提供化合物5和7。从10-CF 3脱水二氢青蒿素3中,在CCl 4中用Br 2也可以高收率进行烯丙基溴化反应。产物5和7与N-,O-和C-亲核试剂反应。从5起,S N和S N '的产物以低至中等的产率获得,而CF 3-取代的烯丙基溴化物7仅经历亲核取代。可以高收率获得新的氟化16取代青蒿素衍生物14a – c。

The present invention relates to compounds with an increased in vivo biological activity, and especially an increased pharmaceutical activity, such as an anti-nematodal or antifungal activity, an immunosuppresive activity, a metabolism influencing activity and/or an anti-cancer activity. Specifically, the present invention relates to compound comprising an artemisinin derivative according to the general formula (I)
covalently linked at the 1 or the 2 position to a compound with a biological activity thereby increasing the biological activity of said compound or a pharmaceutically acceptable salt thereof.
