Hybrid drugs with a twist: The coupling of iron(II)‐promoted trioxolane ring scission with a β‐elimination reaction enables the targeted delivery of multiple drug activities to the malaria parasite. A prototypical fragmenting hybrid (shown) comprises an iron(II)‐reactive 1,2,4‐trioxolane ring (red) joined via a masked retro‐Michael linker (blue) to a partner drug—in this case a protease inhibitor (green)
具有扭曲的混合药物:铁(II)促进的三氧戊环断裂与β-消除反应的偶联能够将多种药物活性靶向递送至疟原虫。原型片段化杂合体(如图所示)包含一个铁(II)反应性 1,2,4-三氧戊环(红色),通过掩蔽的逆迈克尔接头(蓝色)连接到伙伴药物——在这种情况下是蛋白酶抑制剂(绿色) )。使用化学-生物方法证明蛋白酶抑制剂成功递送至红细胞内恶性疟原虫寄生虫。
