  New classes of Gram-positive selective antibacterials: Inhibitors of MRSA and surrogates of the causative agents of anthrax and tuberculosis

  摘要：

  An antimicrobial phenolic stilbene, (E)-3-hydroxy-5-methoxystilbene, 1 was recently isolated from the leaves of Comptonia peregrina (L.) Coulter and shown to possess inhibitory activity against several Gram-positive bacteria, including isolates of methicillin-resistant Staphylococcus aureus (MRSA), Mycobacterium bovis BCG, and avirulent Bacillus anthracis (Sterne strain), among others. These results prompted the design and synthesis of two new classes of compounds, phenoxystyrenes and phenothiostyrenes, as analogs of the natural antimicrobial stilbene. These and additional stilbenoid analogs were synthesized using new, efficient, copper-mediated coupling strategies. Minimum inhibitory concentration (MIC) antimicrobial assays were performed on all compounds prepared. These preliminary structure-activity relationship studies indicated that both new classes of synthetic analogs, as well as the stilbenes, show promising activity against Gram-positive bacteria when at least one phenolic moiety is present, but not when absent. The potencies of the phenolic phenoxystyrenes and phenothiostyrenes were found to be comparable to those of the phenolic stilbenes tested. (C) 2008 Elsevier Ltd. All rights reserved.

  facilitated the Cu-catalyzed cross-coupling reactions of alkyl, aryl, or heterocyclic thiols with either alkyl, aryl, heterocyclic, or substituted vinyl halides. This new catalytic system promoted the mild and efficient stereo- and regiospecific synthesis of biologically important vinyl sulfides. The yields obtained using electron-rich substituted vinyl sulfides with this catalyst system are generally

  顺式-1,2-环己二醇（L3）已被证明是一种高效且通用的双齿O-供体配体，可提供高活性的Cu催化体系。它比诸如反式-1,2-环己二醇或乙二醇之类的二醇更有效。这种市售的顺式-1,2-环己二醇配体有助于烷基，芳基或杂环硫醇与烷基，芳基，杂环或取代的乙烯基卤化物的Cu催化交叉偶联反应。这种新的催化体系促进了生物学上重要的乙烯基硫化物的温和，高效的立体和区域特异性合成。使用富电子取代的乙烯基硫化物在该催化剂体系中获得的产率通常为75-98％。最重要的是，这种奇异的催化剂体系用途极为广泛，可用于多种硫化物。鉴于其温和的反应条件，简便，通用性和卓越的官能团耐受性，该方法尤其值得一提。
