2-arylazoimidazole derivatives 6–20 has been achieved through the reaction of imidazole with aryldiazonium salts, followed by ultrasound-assisted alkylation. This approach has important advantages including higher yield, shorter reaction times and milder reaction conditions. The structures of the compounds obtained were determined by MS, IR; and 1H and 13C NMR. The anti-Trypanosoma cruzi activity of the 15
在这项工作中,合成了一系列2- arylazoimidazole衍生物的6 - 20已经通过与芳基重氮盐的咪唑的反应来实现,随后超声辅助烷基化。该方法具有重要的优点,包括更高的产率,更短的反应时间和更温和的反应条件。所获得的化合物的结构通过MS,IR确定; M + = 1。和1 H和13 C NMR。抗克氏锥虫评价获得的15种化合物的活性。在羧酰胺部分具有哌啶子基取代基的两种化合物被证明是有效的淫前鞭毛虫增殖抑制剂,其抑制值可与参考药物苯并咪唑相比。此外,这些化合物对哺乳动物细胞显示出低细胞毒性。在体内,这两种化合物均能保护小鼠免受致命的克氏锥虫菌株的攻击。这些结果使我们能够提出2-芳基偶氮咪唑作为先导化合物,用于设计治疗查加斯病的新药。
