摘要
Two series of bicyclic oxime ethers viz, 2,4-diaryl-3-azabicyclo[3.3.1]nonan-9-one O-benzyloximes 13-24 and 2,4,6,8-tetraaryl-3,7-diazabicyclo[3.3.1]nonan-9-one O-benzyloximes 31-36 were synthesized and stereochemistry was established by their spectral (1D and 2D NMR) and crystal studies. Synthesized oxime ethers were screened for their in vitro antimicrobial activity against a set of pathogenic bacteria (Pseudomonas aeruginosa, Staphylococcus aureus, Salmonella typhi, Escherichia coli and Klebsiella pneumoniae) and fungi (Candida albicans, Candida-51, Rhizopus sp., Aspergillus niger and Aspergillus flavus) by twofold serial dilution method, respectively, using Ciprofloxacin and Amphotericin B as standards. Most of the molecules expressed promising antimicrobial profile against the tested pathogens and even a few compounds 16, 21, 22, 33 and 34 were better than standard drugs. (C) 2009 Elsevier Ltd.
