The synthesis and reactivity toward a haem model of trioxane derivatives bearing a 1,2-dioxacyclohexane cycle instead of a 1,2-dioxacycloheptane as in artemisinin, and lacking the lactone ring, are reported. The fact that a trioxane able to generate a C-centred radical (without alkylating ability toward a haem model) was devoid of toxicity against Plasmodium also suggests that the efficiency of antimalarial trioxanes is not due to an oxidant stress.
报告了带有 1,2-dioxacyclohexane 循环(而不是青蒿素中的 1,2-dioxacycloheptane)并缺少内酯环的三氧杂环己烷衍生物的合成和对血清模型的反应性。能够产生以 C 为中心的自由基(对血红素模型没有烷基化能力)的三氧环己烷对疟原虫没有毒性,这一事实也表明,抗疟三氧环己烷的效率不是由于氧化应激。
