  Imidazo[4,5-a]quinindolines as highly effective antibacterial agents

  摘要：

  Resistance to antimicrobial agents is a concern that exists globally and has a considerable impact on human and animal health, so that the discovery of new antibacterial compounds has become increasingly more important in combating infectious disease. In this paper, imidazo[4,5-a]quinindolines are introduced as new antibacterial agents against Gram-positive and Gram-negative bacteria. These pentacyclic compounds are synthesized by the reaction of N-alkyl-5-nitrobenzimidazoles with 2-(1-alkyl-1H-3-indolyl)acetonitrile under basic conditions in excellent yields. The structures of newly synthesized compounds were characterized by IR, H-1 NMR, C-13 NMR, and mass spectral data. The antibacterial activities of the synthesized compounds were screened against standard strains of two Gram-positive and two Gram-negative bacteria using the broth microdilution method. Most of the compounds studied showed promising activities against both types of bacteria.

  New N-alkyl-substituted heterocyclic system imidazo[4,5-a]quinindolines (imidazo[4,5-f]indolo[2,3-b]quinolines) were synthesized by one pot reaction of 1-alkyl-5-nitro-1Hbenzimidazole with 2-(1-alkyl-1H-3-indolyl)acetonitrile in basic media via the nucleophilic substitution of hydrogen and concomitant cyclisation in good yields. Physical spectral (UV-vis, IR, NMR and fluorescence) and analytical data
