systematic study of antimalarial 1,2,4-trioxolanes bearing a substitution pattern regioisomeric to that of arterolane. Conformational analysis suggested that trans-3″-substituted trioxolanes would exhibit Fe(II) reactivity and antiparasitic activity similar to that achieved with canonical cis-4″ substitution. The chiral 3″ analogues were prepared as single stereoisomers and evaluated alongside their 4″
我们描述了第一个系统研究抗疟疾1,2,4-三氧戊环具有与青蒿烷的区域异构的取代模式。构象分析表明,反式-3”-取代的三氧杂环戊烷将表现出与标准顺式-4”取代相似的Fe(II)反应性和抗寄生虫活性。将手性3″类似物制备为单一立体异构体,并与它们的4″同类物一起针对培养的疟疾寄生虫和在鼠类疟疾模型中进行评估。如所预测的,反式-3”类似物表现出体外抗血浆活性,与它们的顺式-4”比较物非常相似。相反,在伯氏疟原虫中的功效对于某些同类对,小鼠模型差异很大。新颖的3英寸类似物(例如12i)中最好的一种表现优于青蒿烷本身,单次口服后即可在小鼠中治愈。总的来说,这项研究提出了调节Fe(II)反应性以及1,2,4-三氧戊环抗疟药的药代动力学和药效学性质的新途径。
