Synthesis and spectral characterization of a new class of N-(N-methylpiperazinoacetyl)-2,6-diarylpiperidin-4-ones: Antimicrobial, analgesic and antipyretic studies

A series of N-(N-methylpiperazinoacetyl)-2,6-diarylpiperidin-4-ones (13c-21c) were synthesized by the base catalyzed nucleophilic substitution of N-chloroacetyl-2,6-diarylpiperidin-4-ones obtained from their corresponding 2,6-diarylpiperidin-4-ones with N-methylpiperazine. These newly synthesized compounds were characterized by one- and two-dimensional NMR spectral studies. In all the cases, the piperazine ring adopted normal chair conformation with equatorial orientation of methyl group irrespective of the non-chair conformations of the piperidin-4-one moiety. All the compounds were screened for their possible antibacterial and antifungal activities against a spectrum of microbial agents besides analgesic and antipyretic activities. These biological studies proved that compounds 17c/18c against bacterial and 18c/20c against fungal strains exhibited promising antimicrobial activities whereas 17c/19c and 18c/19c showed beneficial analgesic and antipyretic profiles, respectively, at a concentration of 60 mg/kg and were also found to be more potent than the reference drug.

Chemoselective synthesis and spectral studies of N-thiocyanatoacetyl derivatives of 3-alkyl-2,6-diarylpiperidin-4-ones

A series of N–thiocyanatoacetyl derivatives of 3–alkyl–2,6–diarylpiperidin–4–ones has been synthesized by the reaction between the N–chloroacetyl derivatives of the respective piperidin–4–ones and the ambident thiocyanate nucleophile. The synthesized compounds have been characterized through FT–IR,1H,13C,1H–1H COSY,1H–13C COSY and NOESY spectra. The spectral data reveal the conformational priority of the six-membered heterocyclic ring.

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

The raise in clinical significance of multidrug-resistant bacterial pathogens has directed us to synthesize 2,6-diarylpiperidin-4-one and Δ3-tetrahydropyridin-4-ol based benzimidazole and O-arylsulfonyl derivatives. X-ray crystal structure of t

Synthesis, stereochemistry and antimicrobial evaluation of some N-morpholinoacetyl-2,6-diarylpiperidin-4-ones

In a search for new leads towards potent antimicrobial agents, an array of novel N-morpholinoacetyl-2,6-diarylpiperidin-4-ones has been synthesized and their in vitro antibacterial activity against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Salmonella typhi and antifungal activity against Candida albicans, Rhizopus sp., Aspergillus niger and Aspergillus flavus were evaluated. Structure and stereochemistry of all the N-morpholinoacetyl-2,6-diarylpiperidin-4-ones have been analyzed using 1H and 13C NMR spectroscopic techniques. In all the cases, amide N-C{double bond, long}O group is preferentially in coplanar orientation with respect to the dynamically averaged plane of the piperidone ring. Further, all the symmetrically substituted compounds 19, 23, 24, 26 and 27 are expected to adopt half boat conformations while other compounds 20-22 and 25 adopt twist-boat conformations. Structure-activity relationship results for these nine compounds have shown that compounds 26 and 27 exerted excellent antibacterial activity against all the bacterial strains used except 27 against S. aureus. Against C. albicans and A. flavus, compound 24 recorded excellent antifungal activities while against Rhizopus sp., compound 25 showed potent activities. The obtained results may be used as key step for the building of novel chemical compounds with interesting antimicrobial profiles comparable to that of the standard drugs.

Synthesis and NMR spectral studies of N-chloroacetyl-2,6-diarylpiperidin-4-ones

A series of 2,6-diarylpiperidin-4-ones having electron withdrawing chloroacetyl group at the heterocyclic nitrogen were synthesized. Unambiguous characterizations of the synthesized compounds were achieved by one-dimensional (1H NMR and 13

Synthesis and antimicrobial activities of N-chloroacetyl-2,6- diarylpiperidin-4-ones

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. Birkhaeuser 2007.
