  • Synthesis and antiprotozoal activity of naphthofuranquinones and naphthothiophenequinones containing a fused thiazole ring
    作者:Ricardo A. Tapia、Luz Alegria、Carlos D. Pessoa、Cristian Salas、Manuel J. Cortés、Jaime A. Valderrama、Marie-Elisabeth Sarciron、Félix Pautet、Nadia Walchshofer、Houda Fillion
    DOI:10.1016/s0968-0896(03)00122-6
    日期:2003.5
    The synthesis of tetracyclic quinones 10a,b, 14a,b, 19a,b and 20a,b is described. The preparations involve regioselective Diels-Alder reactions via trapping the thiazole o-quinodimethane 9 with several benzofuranquinones and benzothiophenequinones. The structure of the regioisomers was assigned through 2D NMR H-1-C-13 HMBC experiments performed on 10a and 14a. Compounds 10a,b, 14a as well as phenol I and the starting quinones 2, 5, 7 and 15 are evaluated against Leishmania sp., Toxoplasma gondii and THP-1 cells. Almost all the tested compounds exhibit significant antiprotozoal activities with lower cytotoxicities than the reference compounds. Among them, quitiones 2 and 14a possess the best activities towards L. donovani and T. gondii with the lowest toxicities. (C) 2003 Elsevier Science Ltd. All rights reserved.
  • quinonic derivatives active against a virulent strain of toxoplasma gondii . synthesis of 2-methylfuro[2,3- g ]- and [3,2- g ]isoquinolinetriones
    作者:Pascal Nebois、Marie-Elizabeth Sarciron、Brigitte Bibal、Boufelja Bouammali、Omar Cherkaoui、Félix Pautet、Anne-Françoise Pétavy、Nadia Walchshofer、Houda Fillion
    DOI:10.1016/s0960-894x(00)00112-8
    日期:2000.5
    2-methylfuro[2,3-g]isoquinoline-4,7,9-trione (4) and 2-methylfuro[3,2-g]isoquinoline-4,6,9-trione (5) were prepared regiospecifically from 2-azadiene 9 and bromobenzofuran-4,7-diones 1 or 11. The activity of these two compounds and some other quinonic derivatives was evaluated in vitro against a virulent strain of Toxoplasma gondii. Compounds 4 and 7 were found to be as active as pyrimethamine. (C) 2000 Elsevier Science Ltd. All rights reserved.
