  Design and synthesis of spirocyclic compounds as HCV replication inhibitors by targeting viral NS4B protein

  摘要：

  Two novel series of spirocyclic piperidine analogs appended to a pyrazolo[1,5-alpha] pyridine core were designed, synthesized and evaluated for their anti-HCV activity. A series of piperidine ketals afforded dispiro 6p which showed excellent in vitro anti-HCV activities (EC50 of 1.5 nM and 1.2 nM against genotype 1a and 1b replicons, respectively). A series of piperidine oxazolidinones afforded 27c which showed EC50's of 10.9 nM and 6.1 nM against 1a and 1b replicons, respectively. Both compounds 6p and 27c bound directly to non-structural NS4B protein in vitro (IC50's = 10.2 and 30.4 nM, respectively) and exhibited reduced potency in replicons containing resistance mutations encoding changes in the NS4B protein.

  寡螺酮作为新型分子棒。

  摘要：

  已经开发了一种基于寡螺酮体的分子棒合成的模块化方法。该策略依赖于不同的末端和中间链段，它们通过在酮和二醇之间的缩酮形成而结合在一起。为此，有必要开发一种新的缩酮化方法，以避开与已建立方法有关的一些问题。末端链段衍生自4-哌啶酮或4-氧代环己烷羧酸，而中间链段位于季戊四醇和环己烷-1,4-二酮上。已经制备并表征了一系列三螺（14-18），六螺（19）和壬螺（20）化合物。从这些中我们认识到，如果连接七个以上的环，则必须使用溶解度增强基团。

• Nanoscale Molecular Rods with a New Building Block for Solubility Enhancement
  作者：Pablo Wessig、Kristian Möllnitz

  DOI：10.1021/jo800341k

  日期：2008.6.1

  A new building block bearing a [1,3]dioxolo[4,5-f][1,3]benzodioxole core was developed to enhance the solubility of molecular rods by lateral alkyl chains. On incorporation in molecular rods with oligospiroketal structure, the straight geometry is retained, which was concluded from the X-ray crystal structure analysis of one of the rods. The determination of the solubility of a collection of rods bearing

  开发了一种新的带有[1,3] dioxolo [4,5- f ] [1,3]苯并二恶唑核的结构单元，以通过侧链烷基链增强分子棒的溶解性。在掺入具有低螺缩酮结构的分子棒中时，保留了直的几何形状，这是根据其中一根棒的X射线晶体结构分析得出的结论。确定带有该结构单元的棒的集合的溶解度表明，丁基已经有效地阻碍了棒的聚集，因此导致溶解度的显着提高。哌啶环位于杆的末端，这为通用功能化提供了机会。因此，Ñ，Ñ制备了“-双（叠氮乙酰基）-官能化的棒”，该棒可以通过“点击”反应引发的刚性连接。
• Building Blocks for Oligospiroketal (OSK) Rods and Evaluation of Their Influence on Rod Rigidity
  作者：Pablo Wessig、Kristian Möllnitz

  DOI：10.1021/jo300266b

  日期：2012.4.20

  We report on the synthesis of three new sleeves and their incorporation in OSK rods. The structures of these sleeves are based on neo-inositol, terephthalaldehyde diacetals, and indacene. To quantify the influence of the sleeves on rod rigidity, we applied the worm-like chain (WLC) model on the new rods and found that this approach is rather disappointing. As the chief cause of this result, we assume that the rigidity of typical molecular rods largely exceeds the rigidity of polymers, which were successfully described by the WLC model. Alternatively, we suggest quantifying the rigidity of molecular rods by fitting an empirical function on the end-to-end distance distribution curve obtained by MD simulations. After checking various function types, the Levy-Martin function proved to be most suitable for this purpose. On the basis of this function, we defined the Levy-Martin parameter and suggest using this parameter for the characterization of the rigidity of molecular rods.
