A series of [(4-nitro-1H-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 \mu g.

1,2,4-三唑和 1,3,4-
噻二唑,并评估了它们对敏感和耐药幽门螺杆菌菌株的活性。  对这些系列化合物结构-活性关系的研究表明,硝基
咪唑分子的类型和杂芳基类似物上的悬垂基团对抗幽门螺杆菌活性有显著影响。  在三唑系列中,三唑环上含有 4-甲基苯基的化合物 5d 是对
甲硝唑敏感菌株和耐药菌株抗性最强的化合物,浓度为 8 \mu g。
