  Synthesis and antiprotozoal activity of naphthofuranquinones and naphthothiophenequinones containing a fused thiazole ring

  摘要：

  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.
