Several bicyclic compounds, 3-azabicyclo[3.2.2]nonanes, have been prepared. The new compounds were tested for their activities against one strain of the causative organism of Malaria tropica, Plasmodium falciparum K1, which is resistant against chloroquine and pyrimethamine. In addition, their cytotoxicity and their activity against the pathogen of the East African form of sleeping sickness, Trypanosoma brucei rhodesiense, were investigated. Structure-activity relationships are discussed considering data of readily prepared compounds. For the first time, a distinct in vivo activity was observed against Plasmodium berghei in a mouse model. The active compound was further investigated.
已经制备了几种双环化合物,即3-氮杂双环[3.2.2]壬烷。测试了这些新化合物对热带疟原虫(Plasmodium falciparum K1)这一致病生物体菌株的活性,该菌株对氯喹和乙胺嘧啶具有抗性。此外,还研究了它们的细胞毒性以及对东非昏睡病病原体布氏罗得西亚锥虫(Trypanosoma brucei rhodesiense)的活性。结合易于制备的化合物的数据讨论了构效关系。首次在小鼠模型中观察到对伯氏疟原虫(Plasmodium berghei)有明显的体内活性。对活性化合物进行了进一步研究。
