  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.

  The synthesis of novel thiazole-based piperidinone oximes and screening of their antioxidant and antimicrobial activity are described. The obtained results revealed that the electronic effects of active substituents at C-4 terminals of phenyl rings on either side of piperidinone skeleton, as well as at 2-hydrazinyl thiazole, played a major role in development of antioxidant and antimicrobial activity

  A series of novel quinolinylhydrazones (5a-f) was synthesized by the condensation reaction of 2,6-diarylsubstituted piperidin-4-ones (4a-f) with 7-chloro-4-hydrazinoquinoline (2). Novel quinolinylhydrazones containing Shiff bases 8a-f and 11a-f were obtained via the condensation of Shiff bases 7a-f and 10a-f with 7-chloro-4-hydrazinoquinoline. These synthesized hydrazones were screened for their in vitro antimalarial activities to chloroquine - sensitive (T96) and chloroquine – resistant (K1) strains of P.falciparum. Among the synthesized compounds, 11a exhibited strong antimalarial activity at IC50 of 103.4 ng/mL and 18.76 ng/mL to both strains of P.falciparum, respectively.
