complementarity of the two drug classes – praziquantel and artemisinin deriv-atives – we designed new molecules, named trioxaquantels®, that combine the 1,2,4-trioxane unit responsible for the activity of artemisinin, and the pyrazinoisoquinoline moiety of praziquantel within a single drug. The synthesis of these new drugs and their preliminary evaluation in mice infected with Schistosoma mansoni is reported
在过去的 20 年中,吡喹酮,一种吡嗪基异喹啉衍生物,已成为控制人和动物血吸虫病发病率的中流砥柱。从脊椎动物宿主的生命早期开始,血吸虫吸收血红蛋白并将释放的血红素聚集为一种黑色色素,与疟疾感染中疟原虫产生的血红素非常相似。抗疟药青蒿素衍生物具有真实但低的杀血吸虫活性。由于吡喹酮和青蒿素衍生物这两个药物类别的互补性,我们设计了名为 trioxaquantels® 的新分子,它结合了负责青蒿素活性的 1,2,4-三恶烷单元和吡喹酮的吡嗪异喹啉部分在单一药物内。
