artemisinin using conventional and microwave assisted syntheses, and their structures were confirmed by NMR and HRMS. All derivatives proved to be active against both strains of the parasite. The highest overall activity was displayed by the short chain aromatic derivative 8 (IC50 = 1.44 nM), containing only one nitrogen atom, while long chain polyamine derivatives were found to have the lowest activity against
在这项研究中,合成了一系列 11 种青蒿素 10-氨基乙醚衍生物,并测定了它们对氯喹敏感 (D10) 和抗性 (Dd2)恶性疟原虫菌株的抗疟活性。该化合物是通过使用常规和微波辅助合成方法通过青蒿素 C-10 处的乙醚桥引入具有不同链长连接基的脂肪族、脂环族和芳香族胺基团来制备的,其结构经核磁共振和 HRMS 确证。所有衍生物都被证明对两种寄生虫都有活性。短链芳香族衍生物 8 (IC 50 = 1.44 nM),仅含有一个氮原子,而长链多胺衍生物对两种菌株的活性最低。发现 IC 50、p K a值和电阻指数 (RI)之间存在有趣的相关性。
