    摘要:
    细菌对现有治疗性抗菌药物的耐药性升级已达到关键峰值,导致多重耐药菌株迅速出现。新药发现的严格途径阻碍了我们在这场生存竞赛中的进步。对抗新出现的抗生素耐药性的一种有前途的方法是使用低毒性小分子佐剂增强传统无效的抗菌药物。最近的研究兴趣在于具有独特环状疏水成分的弱膜扰动剂,解决抗菌药物探索中的重大空白。我们的研究表明,基于喹啉的两亲性小分子 SG-B-52 和 SG-B-22 可显着降低选定的 β-内酰胺抗生素(氨苄青霉素和阿莫西林)对致命的耐甲氧西林金黄色葡萄球菌(MRSA) 的 MIC。从机制上讲,膜扰动、去极化和 ROS 生成驱动细胞裂解和死亡。通过溶血测定、细胞毒性分析和对白化 Wistar 大鼠的研究表明,这些分子显示出最小的体外和体内毒性。 SG-B-52 对 MRSA 生物膜表现出令人印象深刻的生物膜清除能力,提出了一种增强 β-内酰胺抗菌作用并鼓励开发有效抗菌增强剂的策略。

    one-pot synthesis of polysubstituted quinoline derivatives has been demonstrated by using sulfamic acid as a reusable catalyst under solvent-free conditions. The synthetic method provides the basis and advantages of a simple experimental procedure and easy recovery and reuse of catalyst, which makes it a highly practical and environmentally benign pathway for the synthesis of polysubstituted quinolines

    A tandem cyclization/aromatization of anilines and aldehydes was achieved under catalytic radical cation salt induced conditions, producing a series of 2,3-disubstituted quinolines in good yields. In this reaction, the in situ generated imine tautomerizes to enamine, which acts as a dienophile to participate in the tandem cyclization, and further elimination of the anilino group triggers the aromatization

    Sulfonic acid functionalized ionic liquid (FIL-A) was firstly used as a recoverable and reusable catalyst for the synthesis of 2-alkylquinoline derivatives from simple and readily available alkylaldehydes and arylamines. The method has the advantages of simple experimental procedure, easy recovery and reuse of catalyst, solvent-free and mild reaction conditions, excellent functional group tolerance, etc. which makes it a highly practical and environmentally benign pathway for the synthesis of 2-alkylquinolines.
  • Oxidant Effect of H<sub>2</sub>O<sub>2</sub>for the Syntheses of Quinoline Derivatives via One-Pot Reaction of Aniline and Aldehyde
    作者:Qiaoxia Guo、Wennian Wang、Weiling Teng、Liwei Chen、Yanqing Wang、Baojian Shen

    日期:2012.9
    A convenient one-pot method for the synthesis of substituted quinolines via the reaction of aniline and aldehyde in the presence of a Lewis acid (AlCl3) and an oxidant (H2O2) has been developed. Hydrogen peroxide was found to promote the reaction by its function as a hydrogen hunter, hindering the formation of by-product N-alkylaniline. The effect of the oxidant on the yield and selectivity was studied. When the molar ratio of aniline, n-butyraldehyde, and H2O2 was 1:3:0.5 at 25 degrees C, the yield of 3-ethyl-2-propylquinoline was improved from 64% (reaction without H2O2) to 84% (with H2O2), and the quinoline selectivity was improved to almost 100%. Moreover, the reaction time was obviously reduced. The substituent effect was also investigated in this work.

    Novel catalyst complexes derived from transition metal and rare-earth metal compounds have been developed for the condensation of anilines with aliphatic and aromatic aldehydes to give the corresponding 2,3-disubstituted quinolines in high yields.
