A series of [(4-nitro-1 H-imidazol-1-yl) methyl]-1,2,4-triazoles and 1,3,4-thiadiazoles were prepared and evaluated for their activity against sensitive and resistant H. pylori strains. Study of the structure-activity relationship of these series of compounds indicated that the type of nitroimidazole moiety and the pendent group on the heteroaryl analog dramatically impact the anti-H. pylori activity. In triazole series, compound 5d, containing a 4-methyl phenyl group on the triazole ring, was the most potent compound tested against both metronidazole-sensitive and-resistant strains at a concentration of 8 μg.

In the reaction of the hydrazide of (4-nitroimidazol-1-yl)acetic acid 1 with isothiocyanates, the respective thiosemicarbazide derivatives 2-6 were obtained. Further cyclization with 2% NaOH led to the formation of 3-[(4-nitroimidazol-1-yl)-methyl]-4-substituted-1,2,4-triazoline-5-thiones 7-11. The structures of all new products were confirmed by analytical and spectroscopic methods. Six compounds 2-5, 8, and 10 were screened for their in vitro activity against some species of aerobic bacteria and fungi. Compound 3 appears to be a promising precursor of agents with antibacterial activity against Micrococcus luteus.
