• Fungal cell wall synthesis gene
  申请人：——

  公开号：US20040038239A1

  公开（公告）日：2004-02-26

  A reporter system reflecting the transport process that transports GPI-anchored proteins to the cell wall was constructed and compounds inhibiting this process were discovered. Further, genes conferring resistance to the above compounds were identified and methods of screening for compounds that inhibit the activity of the proteins encoded by these genes were developed. Therefore, through the novel compounds, the present invention showed that antifungal agents having a novel mechanism, i.e. inhibiting the process that transports GPI-anchored proteins to the cell wall, could be achieved.

  构建了一个反映将GPI锚定蛋白转运到细胞壁的运输过程的报告系统，并发现了抑制该过程的化合物。此外，还鉴定了赋予对上述化合物抗性的基因，并开发了筛选抑制这些基因编码的蛋白质活性的化合物的方法。因此，通过新型化合物，本发明展示了可以实现具有新型机制（即抑制将GPI锚定蛋白转运到细胞壁的过程）的抗真菌剂。

• First synthesis of 4-chloro-2,2-difluoro[1,3]dioxole[4,5-c]pyridine
  作者：Maria Pia Catalani、Alfredo Paio、Lorenzo Perugini

  DOI：10.1016/j.tetlet.2010.10.119

  日期：2010.12

  The 2,2-difluorobenzodioxole moiety has been introduced in medicinal chemistry research as a potential metabolically more stable derivative of the benzodioxole fragment. Herein we present, to the best of our knowledge, the first synthesis of 4-chloro-2,2-difluoro[1,3]dioxole[4,5-c]pyridine, a 5-aza-derivative of the 2,2-difluorobenzodioxole, from simple and cheap starting materials. The chlorine atom in position 4 could be useful for further functionalisation by cross coupling reactions. (C) 2010 Elsevier Ltd. All rights reserved.
