摘要
A series of novel N-hydroxy-3,3-dimethyl-2,6-diarylpiperidin-4-one thiosemicarbazones 28-32 is synthesized, characterized by melting point, elemental analysis, and MS, FT-IR, NMR (1H & 13C) spectroscopic data and evaluated for their in vitro antibacterial and antifungal activities. Of all the compounds synthesized, compound 31 exerted a wide range of antibacterial activities against the entire tested gram-positive and gram-negative bacterial strains except Escherichia coli. Compound 31 exerted strong antifungal activities against Aspergillus flavus, Mucor, and Microsporum gypseum. © 2008 Springer Science+Business Media, Inc.
