chloroperoxidase (VCPO) enzymes is key to this biosynthetic pathway, despite the absence of chlorine in these natural products. This speculation inspired a total synthesis to mimic the naphterpin/marinone biosynthetic pathway. In validation of this biogenetic hypothesis, two VCPOs were discovered that interconvert several of the proposed biosynthetic intermediates.
萘萜品和马里酮是萘醌类萜,具有不寻常的芳香族氧化模式,由 1,3,6,8-四羟基萘 (THN) 生物合成。我们认为,尽管这些天然产物中不含氯,但钒依赖性氯过氧化物酶(VCPO)对 THN 衍生物的神秘卤化是该生物合成途径的关键。这一推测激发了模仿萘平/马里酮生物合成途径的全合成。在验证这一生物遗传学假设时,发现两种 VCPO 可以相互转化几种所提出的生物合成中间体。
