  Decoupling Activation of Heme Biosynthesis from Anaerobic Toxicity in a Molecule Active in Staphylococcus aureus

  摘要：

  Small molecules active in the pathogenic bacterium Staphylococcus aureus are valuable tools for the study of its basic biology and pathogenesis, and many molecules may provide leads for novel therapeutics. We have previously reported a small molecule, 1, which activates endogenous heme biosynthesis in S. aureus, leading to an accumulation of intracellular heme. In addition to this novel activity, 1 also exhibits toxicity towards S. aureus growing under fermentative conditions. To determine if these activities are linked and establish what features of the molecule are required for activity, we synthesized a library of analogs around the structure of 1 and screened them for activation of heme biosynthesis and anaerobic toxicity to investigate structure activity relationships. The results of this analysis suggest that these activities are not linked. Furthermore, we have identified the structural features that promote each activity and have established two classes of molecules: activators of heme biosynthesis and inhibitors of anaerobic growth. These molecules will serve as useful probes for their respective activities without concern for the off target effects of the parent compound.

• Iodocyclisation of Electronically Resistant Alkynes: Synthesis of 2-Carboxy (and sulfoxy)-3-iodobenzo[b]thiophenes

  cyclisation, thus favouring competing addition reactions. Using our previously determined reaction conditions for the 5-endo-dig iodocyclisations of electronically resistant alkynes, we have achieved efficient synthetic access to 2-carboxy (and sulfoxy)-3-iodobenzo[b]thiophenes. The corresponding benzo[b]furans and indoles were not accessible under these conditions. This difference may arise due to the availability

  带有拴系亲核试剂的炔烃的碘环化是构建和多样化杂环的高效方法。该方法的主要局限性是炔类化合物的5 -endo-dig碘环化，它对亲电环化有不利的电子偏倚。这些趋向于将碘鎓原子的亲电子攻击指向错误的碳以进行环化，因此有利于竞争性加成反应。使用我们先前确定的用于电子耐性炔烃的5-内切式碘环化的反应条件，我们已经成功合成了2-羧基（和亚砜氧基）-3-碘代苯并[ b ]噻吩的合成途径。相应的苯并[ b在这些条件下无法获得呋喃和吲哚。这种差异可能是由于在碘代苯并[ b ]噻吩的情况下可利用自由基机理而引起的。碘环化产物的2-羧基官能度可进一步用于迭代炔烃偶联碘环化反应中，其中羧基或亚胺（席夫碱）参与第二次碘环化以生成内酯或吡啶环。
