semisynthetic precursor for its chemical synthesis. Here, we report a chemoenzymatic process that is able to deliver DHAAl using only the sesquiterpene synthase from a carefully designed hydroxylated FDP derivative. This process, which reverses the natural order of cyclization of FDP and oxidation of the sesquiterpene hydrocarbon, provides a significant improvement in the synthesis of DHAAl and demonstrates the
来自青蒿植物的青蒿素是治疗疟疾最有效的药物。在植物中,倍半萜烯环化酶紫穗槐二烯合酶、细胞色素依赖性 CYP450 和醛还原酶将法尼基二磷酸 (FDP) 转化为二氢青蒿醛 (DHAAl),后者是青蒿素生物合成的关键中间体,也是青蒿素化学物质的半合成前体。合成。在这里,我们报道了一种化学酶促过程,该过程能够仅使用来自精心设计的羟基化FDP衍生物的倍半萜合酶来递送DHAAl。该过程逆转了FDP环化和倍半萜烯烃氧化的自然顺序,显着改进了DHAAl的合成,并展示了底物工程在萜烯合酶介导的高价值天然产物合成中的潜力。
