  Synthesis, molecular docking and biological evaluation of coumarin derivatives containing piperazine skeleton as potential antibacterial agents

  摘要：

  A series of 4-hydroxycoumarin derivatives were designed and synthesized in order to find some more potent antibacterial drugs. Their antibacterial activities against Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis and Staphylococcus aureus were tested. These compounds showed good antibacterial activities against Gram-positive strains. Compound 4g represented the most potent antibacterial activity against Bacillus subtilis and S. aureus with MIC of 0.236, 0.355 mu g/mL, respectively. What's more, it showed the most potent activity against SaFabI with IC50 of 0.57 mu M. Molecular docking of 4g into S. aureus Enoyl-ACP-reductase active site were performed to determine the probable binding mode, while the QSAR model was built to check the previous work as well as to introduce new directions.

  A series of substituted 6-nitrophenylpropanamide derivatives (1-20) were synthesized using either the TDAE strategy or classical organic reactions. All these compounds were characterized by fusion point, 1H NMR,13C NMR, elemental analysis or mass spectrometry data. Because of their structural analogy with recently published compounds possessing antinociceptive properties, our derivatives were screened for peripheral analgesic activities on acetic acid-induced writhing in mice. Compound 13 showed the best result at 100 junol/kg ip (50% inhibition vs 59% for aspirin). This antinociceptive activity was maintained after oral administration (40% inhibition vs 31.6% for aspirin). Both hot-plate and actimetry-based tests were non-significant suggesting the analgesic activity of 13 linked to a peripheral mechanism. (C) 2013 Elsevier Masson SAS. All rights reserved.
