  Discovery of a Novel Class of Potent HCV NS4B Inhibitors: SAR Studies on Piperazinone Derivatives

  摘要：

  HTS screening identified compound 2a (piper-azinone derivative) as a low micromolar HCV genotype 1 (GT-1) inhibitor. Resistance mapping studies suggested that this piperazinone chemotype targets the HCV nonstructural protein NS4B. Extensive SAR studies were performed around 2a and the amide function and the C-3/C-6 cis stereochemistry of the piperazinone core were essential for HCV activity. A 10-fold increase in GT-1 potency was observed when the chiral phenylcyclopropyl amide side chain of 2a was replaced with p-fluorophenylisoxazole-carbonyl moiety (67). Replacing the C-6 nonpolar hydrophobic moiety of 67 with a phenyl moiety (95) did not diminish the GT-1 potency. A heterocyclic thiophene moiety (103) and an isoxazole moiety (108) were incorporated as isosteric replacements for the C-6 phenyl moiety (95), resulting in significant improvement in GT-1b and la potency. However, the piperazonone class of compounds lacks GT-2 activity and, consequently, were not pursued further into development.

  The copper(I) catalyzed alkyne-azide cycloaddition (CuAAC), a click reaction, is one of the most powerful catalytic reactions developed during the last two decades. Conducting CuAAC enantioselectively would add a third dimension to this reaction and would enable the direct synthesis of α-chiral triazoles. Doing so is demanding because the two precursors have linear geometries, and the triazole product

  铜 (I) 催化的炔-叠氮环加成 (CuAAC) 是一种点击反应，是过去二十年中开发的最强大的催化反应之一。对映选择性地进行 CuAAC 会为该反应增加第三维，并使直接合成 α-手性三唑成为可能。这样做要求很高，因为这两种前体具有线性几何形状，并且三唑产物是扁平杂环。由于 CuAAC 的复杂机制，设计手性催化剂变得更加复杂。我们报告了动态动力学分辨率 (DKR) 启用的对映选择性 CuAAC (E-CuAAC)。E-CuAAC 产量高，可提供高达 99:1 的 er。E-CuAAC 可以在复杂的分子环境中直接生成 α-手性三唑。
