  摘要：

  人17β-羟类固醇脱氢酶10型是一种多功能蛋白，参与线粒体内的许多酶和结构过程。该酶被认为与几种神经系统疾病有关，例如智力低下，帕金森氏病或阿尔茨海默氏病，其中该酶与淀粉样β肽相互作用。我们基于苯并噻唑基支架制备了约60种新化合物，并评估了它们的抑制能力和作用机理。最有效的抑制剂在苯环部分包含3-氯和4-羟基取代基，在苯并噻唑部分的6位上具有小的取代基，并且两个部分通过脲连接基连接（4at，4bb和4bg）。这些化合物的IC50值为1-2μM，对底物乙酰乙酰辅酶A表现出无竞争性的作用机理。这些17β-羟基类固醇脱氢酶的非竞争性苯并噻唑基抑制剂是有希望用于神经退行性疾病潜在药物的化合物，值得进一步研究和开发。

  Since its discovery 22 years ago, the bacterial cell-to-cell communication system, termed quorum sensing (QS), has shown potential as antipathogenic target. Previous studies reported that ajoene from garlic inhibits QS in opportunistic human pathogen Pseudomonas aeruginosa. In this study, screening of an in-house compound library revealed two sulfur-containing compounds which possess structural resemblance

  自22年前被发现以来，被称为群体感应（QS）的细菌细胞间通讯系统已显示出潜在的抗病原性靶标。先前的研究报道大蒜中的阿jo烯抑制机会性人类病原体铜绿假单胞菌的QS 。在这项研究中，通过对内部化合物库的筛选，发现了两种含硫化合物，它们与阿霍烯具有相似的结构，并在生物报告检测中抑制了QS。经过定量结构-活性关系（SAR）研究，合成了25个含二硫键的类似物，并测试了其QS抑制活性。SAR研究表明，烯丙基可以被其他取代基取代，最活跃的是苯并噻唑衍生物（IC 50= 0.56μM）。这些化合物能够降低QS调节的毒力因子（弹性蛋白酶，鼠李糖脂和绿脓素），并在与植入物相关的感染的小鼠模型中成功抑制铜绿假单胞菌的感染。总之，合成化合物的QS抑制活性令人鼓舞，以进一步探索抗菌药物开发中的新类似物。
