  摘要：

  已经制备了具有许多环A取代基的20S，20RS和20R构型的大量喜树碱（CPT）类似物。拓扑异构酶I（TI）抑制数据（IC50）已通过标准程序获得。通常，具有20S构型的化合物在9或10位上被氨基，卤代或羟基取代会导致TI抑制作用增强。20RS构型的化合物在体外和体内活性较低，而20R构型的化合物则无活性。在TI抑制试验中，在A环上具有10,11-亚甲二氧基取代的化合物显示出显着的效能增强。在包括L-1210小鼠白血病测定法在内的各种体内测定法中确定的某些类似物的活性通常与TI抑制作用一致。制备了许多水溶性类似物，例如20-甘氨酸酯，9-甘氨酰胺或水解的内酯盐，并在体外和体内试验中进行了测试。通常，就L-1210分析中的TI抑制作用和寿命延长而言，这些化合物的活性均不如CPT。然而，某些20-甘氨酸酯在静脉内给药后显示出良好的体内活性。

• One-Pot Allan-Robinson/Friedländer Route to Chromen-/Quinolin-4-ones through the Domino Acetylative Cyclisation of 2-Hydroxy-/2-Aminobenzaldehydes
  作者：Vijai K. Rai、Fooleswar Verma、Ganeshwar P. Sahu、Manorama Singh、Ankita Rai

  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.

  A general strategy for the identification of selective cholesterol transport protein inhibitors through the synthesis of a diverse sterol-inspired compound collection is presented. Fusion of a primary sterol scaffold to diverse secondary natural product-derived scaffolds afforded hits against all of the Aster family of cholesterol transport proteins and selective inhibitors of Aster-C.

  Quinoline derivatives are important natural products and pharmaceuticals, but their synthesis can be challenging due to poor yields, harsh reaction conditions, and instability of starting materials. Here we report the chemoenzymatic synthesis of quinaldic acids under mild conditions using an aldolase, trans-o-hydroxybenzylidenepyruvate hydratase-aldolase (NahE, or HBPA). A series of 2-aminobenzaldehydes

  喹啉衍生物是重要的天然产物和药物，但由于收率低、反应条件苛刻和起始材料不稳定，它们的合成具有挑战性。在这里，我们报告了使用醛缩酶、反式-o-羟基亚苄基丙酮酸水合酶-醛缩酶（NahE 或 HBPA）在温和条件下化学酶法合成喹哪二酸。在 NahE 存在下，一系列源自相应硝基类似物还原的 2-氨基苯甲醛与丙酮酸反应，以高达 93% 的分离产率得到取代的喹啉。该反应不同于体内NahE 催化的羟醛缩合，而是类似于由其同源物二氢吡啶二羧酸合酶催化的杂环形成。
