  Quinolinyl Pyrimidines: Potent Inhibitors of NDH-2 as a Novel Class of Anti-TB Agents

  摘要：

  NDH-2 is an essential respiratory enzyme in Mycobacterium tuberculosis (Mtb), which plays an important role in the physiology of Mtb. Herein, we present a target-based effort to identify a new structural class of inhibitors for NDH-2. High-throughput screening of the AstraZeneca corporate collection resulted in the identification of quinolinyl pyrimidines as the most promising class of NDH-2 inhibitors. Structure-activity relationship studies showed improved enzyme inhibition (IC50) against the NDH-2 target, which in turn translated into cellular activity against Mtb. Thus, the compounds in this class show a good correlation between enzyme inhibition and cellular potency. Furthermore, early ADME profiling of the best compounds showed promising results and highlighted the quinolinyl pyrimidine class as a potential lead for further development.

• One-Pot Allan-Robinson/Friedländer Route to Chromen-/Quinolin-4-ones through the Domino Acetylative Cyclisation of 2-Hydroxy-/2-Aminobenzaldehydes

  A domino reaction between 2‐hydroxy‐/2‐aminobenzaldehydes and α‐haloketones gives chromen‐4‐ones and quinolin‐4‐ones in good to excellent yields. This method represents a new extension of the Allan–Robinson and Friedländer reactions, and uses N‐heterocyclic‐carbene catalysis. This approach has the advantages of operational simplicity, ambient reaction conditions, and no by‐product formation.

  2-羟基/ 2-氨基苯甲醛与α-卤代酮之间的多米诺反应使chromen-4-ones和quinolin-4-ones的产率高到极好。该方法代表了Allan-Robinson和Friedländer反应的新扩展，并使用了N-杂环-卡宾催化。这种方法的优点是操作简单，环境反应条件好，并且不会形成副产物。
• Synthesis of 4-Quinolones via a Carbonylative Sonogashira Cross-Coupling Using Molybdenum Hexacarbonyl as a CO Source

  A palladium-catalyzed CO gas-free carbonylative Sonogashira/cyclization sequence for the preparation of functionalized 4-quinolones from 2-iodoanilines and alkynes via two different protocols is described. The first method (A) yields the cyclized products after only 20 min of microwave (MW) heating at 120 degrees C. The second method (B) is a gas-free one-pot two-step sequence which runs at room temperature, allowing the use of sensitive substituents (e.g., nitro and bromide groups). For both protocols, molybdenum hexacarbonyl was used as a solid source of CO.
