chemistry. In the present work, we describe the preparation of new bicyclic thiazolidinyl-1,4-thiazepines 3 by reaction between azadithiane compounds and Michael acceptors. The reaction scope was explored and the yields were optimized. The activity of the new compounds was evaluated against Nippostrongylus brasiliensis and Caenorhabditis elegans as anthelmintic models and Trypanosoma brucei brucei. The most
1,4-硫氮杂类衍生物是药理学上重要的杂环化合物,在药物化学中有不同的应用。在目前的工作中,我们描述了通过氮杂二硫烷化合物和迈克尔受体之间的反应制备新的双环噻唑烷基-1,4-噻氮杂3 。探索了反应范围,优化了收率。新化合物的活性针对作为驱虫模型的Nippostrongylus brasiliensis和Caenorhabditis elegans和布氏锥虫进行了评估。最活跃的化合物是3l ,对T. b.显示出 EC 50 = 2.8 ± 0.7 μM 。brucei和选择性指数 >71。
