etiologic agent of Chagas disease. Based on this result, 16 new N-alkyl-naphthoimidazoles derived from 6,6-dimethyl-3,4,5,6-tetrahydrobenzo[7,8]chromene[5,6-d]imidazole (the product of the reaction of β-lapachone with paraformaldehyde) by its reaction with halo-alkanes were prepared and evaluated against the parasite and peritoneal macrophages. The N1-n-hexyl and N3-n-hexyl naphthoimidazoles were 2.2 and
的34的2-芳基naphthoimidazoles的构效关系研究筛选到目前为止揭示σ我是用于在血流锥鞭毛体形式的它们的裂解活性的最重要因素克氏锥虫,美洲锥虫病的病原体。根据此结果,从16,6-二甲基-3,4,5,6-四氢苯并[7,8]亚甲基[5,6- d ]咪唑衍生出16种新的N-烷基-萘咪唑(通过与卤代烷烃反应制备β-拉帕酮和低聚甲醛,并针对寄生虫和腹膜巨噬细胞进行评估。所述Ñ 1- ñ -己基和Ñ 3- Ñ-己基萘咪唑的活性分别是标准药物苯硝唑的2.2倍和3.2倍,选择性指数分别为2.7和13.4。
