    摘要:
    (-)-和(+)-松柏醇内酯1已从2,3-O-异丙叉基-β-赤-五碳糖醛酸(1)中合成,而1则分别由D-或L-木糖简便制得。1与3-氧基辛酸进行缩合,随后将酯与TFA:H2O(9:1)处理,得到松柏醇内酯1,两步收率为6.3%。按照相同的合成路线,用3-氧基-7-辛烯酸替代3-氧基辛酸,得到了(-)-Δ(7)-松柏醇内酯1,收率为5.8%。还制备了阿拉伯糖和果糖的初级P-酮酸酯,以测试生物模拟环化反应生成松柏醇内酯类似物的选择性。

    structural analogues is of significant biological interest in the development of methods to manipulate bacterial quorum sensing systems in a useful fashion. In this Letter we report robust routes for the synthesis of a range of N-acylated-l-homoserine lactone (AHL) quorum sensing molecules. Crucially, we have analysed the enantiopurity of the final AHLs and in all cases, excellent levels were observed.

    for antibacterial activity against Gram-positive and Gram-negative bacteria. We found a direct relationship between antibacterial activity and C3/C6 alkyl chain length. For inhibition of Gram-positive bacteria, alkyl chain lengths between 6 and 7 carbons were found to be the most active (IC50=0.04-3.8µg/mL) whereas short alkyl chain analogs showed modest activity against Gram-negative bacteria (IC50=223-304µg/mL)

  • Haloperoxidase Mediated Quorum Quenching by Nitzschia cf pellucida: Study of the Metabolization of N-Acyl Homoserine Lactones by a Benthic Diatom

    Diatoms are known to produce a variety of halogenated compounds, which were recently shown to have a role in allelopathic interactions between competing species. The production of these compounds is linked to haloperoxidase activity. This research, has shown that this system may also be involved in diatom-bacteria interactions via the H2O2 dependent inactivation of a type of quorum sensing (QS) molecule, i.e., N-β-ketoacylated homoserine lactones (AHLs), by a natural haloperoxidase system from the benthic diatom Nitzschia cf pellucida. The AHL degradation pathway towards corresponding halogenated derivatives was elucidated via HPLC-MS analysis and the synthesis of a broad series of novel halogenated AHL analogues as reference compounds. Furthermore, their biological activity as quorum sensing modulators was directly compared and evaluated against a series of naturally occurring β-keto-AHLs. It has been demonstrated that the loss of the QS activity results from the final cleavage of the halogenated N-acyl chain of the signal molecules.
    硅藻已知能够产生多种卤化化合物,最近的研究表明这些化合物在竞争物种之间的化感作用中起着重要作用。这些化合物的产生与卤过氧化酶活性有关。这项研究表明,该系统可能还通过来自底栖硅藻Nitzschia cf pellucida的天然卤过氧化酶系统,通过H2O2依赖性的失活过程,参与硅藻与细菌的相互作用,这种失活作用针对的是一种类型的群体感应(QS)分子,即N-β-酮基化同型丝氨酸内酯(AHLs)。通过HPLC-MS分析阐明了AHL降解通路及其对应的卤化衍生物,并合成了一系列新型卤化AHL类似物作为参考化合物。此外,其作为群体感应调节剂的生物活性与一系列天然存在的β-酮-AHL进行了直接比较和评估。研究表明,群体感应活性的丧失是由于信号分子的卤化N-酰链的最终裂解。
