  • Discovery and SAR study of piperidine-based derivatives as novel influenza virus inhibitors
    作者:Guoxin Wang、Longjian Chen、Tongmei Xian、Yujie Liang、Xintao Zhang、Zhen Yang、Ming Luo
    DOI:10.1039/c4ob01079e
    日期:——
    A series of piperidine-based derivatives were identified as novel and potent inhibitors of the influenza virus through structural modification of a compound that was selected from a high-throughput screen. Various analogues were synthesized and confirmed as inhibitors. The structure–activity relationship (SAR) studies suggested that the ether linkage between the quinoline and piperidine is critical for the inhibitory activity. The optimized compound tert-butyl 4-(quinolin-4-yloxy)piperidine-1-carboxylate 11e had an excellent inhibitory activity against influenza virus infection from a variety of influenza virus strains, with EC50 values as low as 0.05 μM. The selectivity index value (SI = MLD50/EC50) of 11e is over 160 000 based on cytotoxicity, measured by MTT assays of three cell lines. We carried out a time-of-addition experiment to delineate the mechanism of inhibition. The result indicates that 11e interferes with the early to middle stage of influenza virus replication.

  • Novel one pot synthesis of 2-amino-4-chloroquinolines via Smiles rearrangement
    作者:Devadoss Karthik Kumar、Subramaniam Parameswaran Rajendran

    日期:2012.6
    We have developed a novel one pot synthesis of 4-chloroquinolin-2-ylamines via Smiles rearrangement under milder condition. The key transformation involves O-alkylation of 4-chloro-1H-quinolin-2-ones with chloroacetamide followed by Smiles rearrangement. The scope of this methodology is further extended to the synthesis of 4-chloroquinolin-2-ylmethylamines and 2-(4-chloroquinolin-2-ylamino)ethanols
    我们已经开发了一种在温和条件下通过Smiles重排合成4-氯喹啉-2-基胺的新型一锅法。关键转化涉及用氯乙酰胺对4-氯-1 H-喹啉-2-酮进行O-烷基化,然后进行Smiles重排。该方法的范围进一步扩展至4-氯喹啉-2-基甲胺和2-(4-氯喹啉-2-基氨基)乙醇的合成。该方法提供了2-氨基-4-氯喹啉的良好产率。
  • Identification and molecular modeling of new quinolin-2-one thiosemicarbazide scaffold with antimicrobial urease inhibitory activity
    作者:Mohammed A. I. Elbastawesy、Yaseen A. M. M. El-Shaier、Mohamed Ramadan、Alan B. Brown、Ashraf A. Aly、Gamal El-Din A. Abuo-Rahma

    A new series of 6-substituted quinolin-2-one thiosemicarbazides 6a–j has been synthesized. The structure of the target compounds was proved by different spectroscopic and elemental analyses. All the designed final compounds were evaluated for their in vitro activity against the urease-producing R. mucilaginosa and Proteus mirabilis bacteria as fungal and bacterial pathogens, respectively. Moreover, all compounds were in vitro tested as potential urease inhibitors using the cup-plate diffusion method. Compounds 6a and 6b were the most active with (IC50 = 0.58 ± 0.15 and 0.43 ± 0.09 µM), respectively, in comparison with lead compound I (IC50 = 1.13 ± 0.00 µM). Also, the designed compounds were docked into urease proteins (ID: 3LA4 and ID: 4UBP) using Open Eye® software to understand correctly about ligand–receptor interactions. The docking results revealed that the designed compounds can interact with the active site of the enzyme through multiple strong hydrogen bonds. Moreover, rapid overlay of chemical structures’ analysis was described to understand the 3D QSAR of synthesized compounds as urease inhibitors. The results emphasize the importance of polar thiosemicarbazide directly linked to 6-substituted quinolone moieties as promising antimicrobial urease inhibitors.
    一系列6-取代的喹啉-2-酮硫脲6a–j已被合成。目标化合物的结构通过不同的光谱和元素分析得到证实。所有设计的最终化合物分别对产生脲酶的R. mucilaginosa和Proteus mirabilis细菌作为真菌和细菌病原体的体外活性进行了评估。此外,所有化合物在体外采用杯盘扩散法作为潜在的脲酶抑制剂进行了测试。化合物6a和6b活性最强,分别为(IC50 = 0.58 ± 0.15和0.43 ± 0.09μM),与先导化合物I(IC50 = 1.13 ± 0.00μM)相比。此外,设计的化合物通过Open Eye®软件对接入脲酶蛋白(ID:3LA4和ID:4UBP),以正确理解配体-受体相互作用。对接结果显示,设计的化合物可以通过多个强氢键与酶的活性位点相互作用。此外,还描述了化学结构的快速叠加分析,以理解合成的化合物作为脲酶抑制剂的3D QSAR。结果强调了直接连接到6-取代喹诺酮部分的极性硫脲作为有前途的抗菌脲酶抑制剂的重要性。
