5-Nitroimidazole derivatives as possible antibacterial and antifungal agents

Abstract

Some novel 1-[2-[[5-(2-furanyl)-4-substituted 4H-1,2,4-triazol-3-yl]thio]ethyl]-2-methyl-5-nitro-1H-imidazoles (3), 1-[3-[[5-(2-furanyl/2-thienyl)-4-substituted 4H-1,2,4-triazol-3-yl]-thio]-2-hydroxypropyl]-2-methyl-5-nitro-1H-imidazoles (5) and 1-[3-[(N,N-disubstituted thiocarbamoyl)-thio]-2-hydroxypropyl]-2-methyl-5-nitro-1H-imidazoles (7) were synthesized and evaluated for in vitro antibacterial and antifungal activity. Some of 5 were found to be effective against bacteria and fungi (minimum inhibitory concentration (MIC) 7.3-125 mu g/ml), whereas 7 were found to be effective against fungi (MIC 3-25 mu g/ml).
