  Mixed Steroidal 1,2,4,5-Tetraoxanes:  Antimalarial and Antimycobacterial Activity

  摘要：

  Mixed 1,2,4,5-tetraoxanes possessing simple spirocycloalkane and spirocholic acid-derived substituents were prepared and shown to have significantly higher in vitro antimalarial activity than bis-substituted tetraoxanes. Out of 41 synthesized tetraoxanes, 12 were in vitro more potent against Plasmodium falciparum chloroquine-resistant W2 clone than artemisinin, and the most potent one was 2.4 times as active as arteether. In addition, 9 compounds exhibit higher activity than chloroquine against P. falciparum chloroquine-susceptible D6 clone. Cytotoxicity was assessed for most active compounds against the Vero cell line, showing a cytotoxicity/antimalarial potency ratio of 1/(1400-9500). For the first time, tetraoxanes were screened against Mycobacterium tuberculosis with MICs as low as 4.73 muM against H37Rv strain. Mixed tetraoxanes were synthesized in a simple procedure from cholic acid methyl esters by direct coupling of steroidal gem-dihydroperoxide to simple ketones and further transformed into corresponding acids and amides.

  The development of widespread drug resistance to chloroquine (CQ(a)) has resulted in severe health issues for countries in malaria endemic regions. The antimalarial properties of artemisinin 2 and of other peroxides, such as 1,2,4,5-tetraoxacy-cloalkanes (tetraoxanes), have recently begun to be exploited in the development of new approaches to fighting CQ-resistant strains of malaria. New tetraoxanes employing a steroidal backbone have now been prepared that are highly active, are inexpensive, and demonstrate low toXieity.(5,6) A part of our research in this field is focused on the development of a new type of tetraoxane with nonidentical substituents(6) that utilize a steroid and small cyclohexylidene carriers possessing secondary amide bonds. Also, during our work in this field we discovered that tetraoxanes are unusually stable, even. at pH 1.6,(6c) a characteristic that subsequently allowed the synthesis of many interesting derivatives. This communication encompasses the synthesis of various amino-functionalized antimalarials based on the appreciable stability of the tetraoxane moiety to reaction conditions such as reductive amination and LiAlH4 reduction. Their respective antimalarial activities and the pronounced antiproliferative activity of certain products are reported along with in vitro metabolism studies.
