Plakortin (1) is a remarkably simple 1,2-dioxane derivative, extracted from the marine sponge Plakortis simplex, showing a submicromolar activity against chloroquine-resistant strains of Plasmodium falciparum. Using plakortin as a novel antimalarial hit, we have prepared a series of semisynthetic derivatives in order to gain insights into the structural requirements of simple 1,2-dioxanes for exhibiting
Plakortin(1)是一种非常简单的1,2-二恶烷衍生物,是从海洋海绵Plakortis simplex中提取的,对恶性疟原虫的耐氯喹菌株具有亚微摩尔活性。使用普拉考丁作为一种新型抗疟疾药物,我们准备了一系列半合成衍生物,以深入了解显示抗疟疾活性的简单1,2-二恶烷的结构要求。本文报道了它们的合成,光谱和计算分析以及体外抗疟活性。获得的结果除了证实了环过氧化物功能的关键作用外,还揭示了对抗疟疾活性至关重要的其他结构特征,即“西方”烷基侧链,二恶烷环构象和立体异构碳在1上的绝对构型
