and the alkylative property of synthetic tricyclic trioxanes 5–10 is reported. Thus, trioxanes 5 and 7, substituted at the C-5a angular position by a methyl or a cyano group, proved to be completely devoid of antimalarial activity, and did not alkylate the heme model MnIITPP. In contrast, both the anti-Plasmodium activity and the alkylative property were restored in the C-5a-unsubstituted analog 8, bearing
据报道,抗疟效力与合成三环三恶烷 5-10 的烷基化特性之间存在明确的相关性。因此,在 C-5a 角位置被甲基或氰基取代的三恶烷 5 和 7 被证明完全没有抗疟活性,并且不会使血红素模型 MnIITPP 烷基化。相比之下,在 C-5a 未取代的类似物 8 中,抗疟原虫活性和烷基化特性都得到了恢复,在 C-3 处带有甲氧基甲基。8 与 MnIITPP 的反应提供了共价加合物 18,这是由血红素模型捕获甲氧基甲基自由基产生的。所有这些结果强化了金属卟啉与药物的过氧化物键密切相互作用以激活这些三恶烷抗疟药的假设。
