  A new class of small molecule RNA polymerase inhibitors with activity against Rifampicin-resistant Staphylococcus aureus1

  摘要：

  The RNA polymerase holoenzyme is a proven target for antibacterial agents. A high-throughput screening program based on this enzyme from Staphylococcus aureus had previously identified a 2-ureidothiophene-3-carboxylate as a low micromolar inhibitor. An investigation of the relationships between the structures of this class of compounds and their inhibitory- and antibacterial activities is described here, leading to a set of potent RNA polymerase inhibitors with antibacterial activity. Characterization of this bioactivity, including studies of the mechanism of action, is provided, highlighting the power of the reverse chemical genetics approach in providing tools to inhibit the bacterial RNA polymerase.

• PROCESS FOR PRODUCING HIGHER CYANOACETIC ESTER
  申请人：NITTO CHEMICAL INDUSTRY CO., LTD.

  公开号：EP0685460A1

  公开（公告）日：1995-12-06

  A higher cyanoacetic ester NCCH₂COOR' (wherein R' represents C₄-C₂₀ alkyl) is produced by the transesterification between a cyanoacetic ester NCCH₂COOR¹ (wherein R¹ represents C₁-C₃ alkyl) and an alcohol R'OH (wherein R' is as defined above) in the presence of a catalyst comprising a specified tin compound. The process enables a higher cyanoacetic ester useful as the intermediates of medecines, agricultural chemicals and industrial products to be produced from inexpensive and readily available cyanoacetic ester and alcohol more simply in a higher yield as compared with the conventional processes.

  氰乙酸酯 NCCH₂COOR'（其中 R'代表 C₄-C₂₀烷基）与醇 R'OH（其中 R'如上文所定义）在由特定锡化合物组成的催化剂存在下发生酯交换反应，从而制得高级氰乙酸酯 NCCH₂COOR¹（其中 R¹ 代表 C₁-C₃烷基）。与传统工艺相比，该工艺能更简便地利用廉价易得的氰乙酸酯和醇生产出用作药物、农用化学品和工业产品中间体的高级氰乙酸酯，且收率更高。
