  摘要：

  In the present work, a new series of bis hybrid heterocycle comprising both piperidine and thiohydantoin nuclei together namely 3-(3-alkyl-2,6-diarylpiperin-4-ylidene)-2-thioxoimidazolidin-4-ones 46-60 was synthesized by the treatment of the respective thiosemicarbazones 31-45 with chloroethyl acetate and anhydrous sodium acetate in refluxing ethanol for 4 h and were characterized by melting point, elemental analysis, MS, FT-IR, one-dimensional NMR (H-1, D2O exchanged H-1 and C-13), two dimensional HOMOCOSY and NOESY spectroscopic data. In addition, the title compounds were screened for their antimicrobial activities against a spectrum of clinically isolated microbial organisms. Compounds 47-50, 52-55 and 57-60 with fluoro, chloro, methoxy or methyl functions at the para position of phenyl rings attached to C-2 and C-6 carbons of piperidine moiety along with and without methyl substituent at position C-3 of the piperidine ring exerted potent biological activities againstStaphylococcus aureus, beta-Hemolytic streptococcus, Vibrio cholerae, Escherichia coli, Pseudomonas aeruginosa, Aspergillus flavus, Candida albicans, Candida 6 and Candida 51 at a minimum inhibitory concentration.

  Three series of oxime ethers viz, 2,6-diarylpiperidin-4-one O-benzyloximes 5a-o, 2,6-diaryltetrahydropyran-4-one O-benzyloximes 7a-e and 2,6-diaryltetrahydrothiopyran-4-one O-benzyloximes 11a-b and 12a-c were synthesized and stereochemistry is established by their spectral and single crystal analysis. A SAR study has been carried out for the above oxime ethers against a panel of antibacterial (Pseudomonas aeruginosa, Staphylococcus aureus, Salmonella typhi and Escherichia coli) and antifungal agents (Candida albicans, Candida-51, Rhizopus sp., Aspergillus niger, Aspergillus flavus and Cryptococcus neoformans), respectively, using Ciprofloxacin and Amphotericin B as standards. Most of the chloro/methyl/methoxy substituted compounds exerted moderate to good activity against all the tested organisms; moreover, some compounds (5i, 5l, 5n, 5o, 7c2, 7d1, 7d2, 7e, 11b and 12c) exhibited promising activity than standard drugs.

  Some novel spiropiperidinyl-1,2,4-triazolidin-3-thiones have been synthesized and studied for their antibacterial activity against Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Pseudomonas aeruginosa and antifungal activity against Candida albicans, Candida-6, Candida-51, Aspergillus niger and Aspergillus flavus. Compounds 30-32 exhibited potent in vitro antibacterial activity against E. coli and P. aeruginosa whereas the same set of compounds exerted potent in vitro antifungal activity against Candida-6, A. niger and A. flavus.

  Some 2,6-diarylpiperidin-4-one thiosemicarbazones (1a-8a), obtained from the corresponding 2,6-diarylpiperidin-4-ones (1-8) on oxidative cyclization with H2O2 at OdegreesC provide 7,9-diaryl-1,2,4,8-tetraaza spiro[4.5]decan-3-thiones(1b-8b) in excellent yields. The structures of these compounds have been established on the basis of their elemental, analytical and spectral data.
