  4-羟基喹啉-2（1 H）-ones的设计，合成及抗结核功效

  摘要：

  在这项研究中，设计了一个由50个成员组成的，由4-羟基喹啉2（1 H）-取代基和两个密切相关的类似物组成的文库，对该文进行了计算机模拟评分，随后进行了合成。共有13个共有3-苯基取代基的13种衍生物对10μM以下的结核分枝杆菌H37Ra和牛分枝杆菌的抑制作用最小低于15μM的AN5A对快速生长的分枝杆菌物种无活性。在活性浓度范围内，在Vitotox™分析中，这些选择的衍生物均未显示出对MRC-5细胞具有明显的急性毒性或遗传毒性的早期迹象。结构活性研究的关系为4-羟基喹啉-2（1 H）-one支架和6-氟-4-羟基-3-苯基喹啉-2（1 H）-one（1 ）的进一步有利的取代方式提供了一些见识。38）被选为库中最有前途的成员，MIC为3.2μM，针对MRC-5的CC 50为67.4μM。

• Novel Solid-Phase Synthetic Method for Combinatorial Generation of a 4-Hydroxyquinolin-2(1<i>H</i>)-one-Based Library

  日期：2007.6

  Utilizing polymer-bound anthranilic acid derivatives, we were able to obtain 4-hydroxyquinolin-2(1H)-ones in 50-99% five- or six-step overall yields and 65-95% purities through the adaptation of a Dieckmann-type condensation reaction to a C-C bond-forming cyclative cleavage step. The reactions on solid phase were monitored by on-bead ATR-FTIR spectroscopic methods, colorimetric tests, and/or cleavage experiments.

  利用聚合物结合的邻氨基苯甲酸衍生物，我们通过将迪克曼型缩合反应调整为C-C键形成的环化断裂步骤，获得了产率为50-99%的五步或六步总产率以及纯度为65-95%的4-羟基喹啉-2(1H)-酮。固相反应通过珠上ATR-FTIR光谱学方法、比色测试和/或断裂实验进行监测。
• Novel Ring Contraction of 3-Hydroxy-2,4(1<i>H</i>,3<i>H</i>)-quinolinediones in Aqueous Alkali. The First Convenient Route to 2-Hydroxyindoxyls

  日期：2001.9.1

  Ring contraction of 3-hydroxy-2,4(1H,3H)-quinolinediones (1) in aqueous potassium hydroxide resulted in the formation of 2-hydroxyindoxyls and/or dioxindoles. The choice of N-substituent and the reaction conditions govern the chemoselectivity of the reaction. N-Phenyl-substituted derivatives 1 give 2-hydroxyindoxyls, while N-alkyl- and N-benzyl-substituted derivatives afford the corresponding dioxindols. On the basis of byproduct analysis, as well as independent experiments, the most plausible reaction mechanism is proposed.
• Halogenation reactions in position 3 of quinoline-2,4-dione systems by electrophilic substitution and halogen exchange

  日期：——

  3-Substituted 4-hydroxy-2(1 H)-quinolones 3, 5, 7 are halogenated with bromine or sulfuryl chloride to yield the quinolinediones 9 or 10. Reaction of 3, 5, 7 with chloroform gives the dichloromethyl quinolinediones 11. Halogen exchange leads from the chloro quinolinediones 10 to fluoro quinolinedones 12 and to azido quinolinediones 13. Similarly the dichloro quinolinedione 10 an reacts to the difluoro quinolinedione 14, which is reduced to the 3-fluoro-4-hydroxyquinolone 16 and reacts again with sulfuryl chloride to give the mixed 3-chloro-3-fluoroquinolinedione 15.
