We synthesized new naphthoimidazoles from beta-lapachone with an aromatic moiety linked to the imidazole ring, using phenylic and heterocyclic aldehydes. The most active compound against Trypanosoma cruzi had a p-methyl group linked to the phenyl ring, presenting an EC(50) value of 15.5 +/- 2.9 microM. No reliable correlation could be established with the biological activity and the structure of in
我们使用苯基和杂环醛从 β-lapachone 合成了新的萘咪唑,其中芳香部分与咪唑环相连。针对克氏锥虫最活跃的化合物有一个与苯环相连的对甲基基团,呈现出 15.5 +/- 2.9 microM 的 EC(50) 值。不能与苯基系列中的生物活性和结构建立可靠的相关性。根据我们之前的工作,对于杂环系列,活性与从氮到咪唑环的三键距离有关。
