  A facile synthesis, antibacterial, and antitubercular studies of some piperidin-4-one and tetrahydropyridine derivatives

  摘要：

  The raise in clinical significance of multidrug-resistant bacterial pathogens has directed us to synthesize 2,6-diarylpiperidin-4-one and Delta(3)-tetrahydropyridin-4-ol based benzimidazole and O-arylsulfonyl derivatives. X-ray crystal structure of tetrahydropyridinol (23) confirmed a change in conformation and orientation of substituents upon amide formation. Antibacterial activities evaluated against a wide number of bacterial pathogens (both sensitive and multidrug-resistant) revealed that 19, 27 against Staphylococcus aureus, 27 against Enterococcus faecalis, and 19, 21, 23, and 27 against Enterococcus faecium are significantly good at lowest MIC90 (16 mu g/mL). Inhibitory power noticed by 23 against Vancomycin-Linezolid-resistant E. faecalis and 27 against Vancomycin-resistant E. faecium are onefold better than the standard Linezolid and Trovafloxacin drugs, respectively. Moreover, antitubercular activity for the selected compounds against Mycobacterium tuberculosis H37Rv revealed that compounds 23, 24, and 27 expressed onefold improved potency compared to the standard Rifampicin drug.

  An array of new N-chloroacetyl-2,6-diarylpiperidin-4-ones has been synthesised and their antibacterial activity against Staphylococcus aureus, Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, and Salmonella typhi, and antifungal activity against Cryptococcus neoformans, Candida albicans, Rhizopus sp., Aspergillus flavus, and Aspergillus niger examined. Compounds 14 against P. aeruginosa, 15 against S. typhi, 16 against S. aureus, and 19 against B. subtilis showed marked antibacterial activity. Similarly, compounds 15 and 19 against A. niger and 19 against A. flavus exerted significant antifungal activities.

  A new series of 1-[2-(4-ethoxycarbonylpiperazine-1-yl)acetyl]-2,6-diarylpiperidin-4-ones (3a-3j) has been synthesized by conventional method and were characterized by IR, elemental analysis, mass spectral, 1 H NMR, C-13 NMR, and single crystal X-ray diffraction analysis. The synthesized compounds were evaluated for their antituberculosis activity against Mycobacterium tuberculosis H37Rv (ATCC-27294) and also its antimicrobial activity were examined against five familiar bacterial and fungal strains. Among the synthesized compounds, compounds 3e-3j exhibit higher inhibition potency (16 mu g/ml) against M. tuberculosis H37Rv. Furthermore, compounds containing fluoro substituent in the phenyl ring at C-2 and C-6 positions of the piperidin-4-one motif (compounds 3c, 3d, and 3i) exerted better antibacterial and antifungal activity than the other phenyl-substituted compounds.
