Disclosed are novel imidazole derivatives having the formula: ##STR1## wherein R.sup.1 and R.sup.2 are H, alkyl, cycloalkyl, aryl, aralkyl or halogen-substituted alkyl, or R.sup.1 and R.sup.2 are combined to form a heterocyclic ring; R.sup.3, R.sup.4, R.sup.5 and R.sup.6 are H, halogen, alkoxy, aralkyloxy, alkyl, alkoxycarbonyl, nitro, amino, acyl, fluorine substituted-alkyl, or fluorine substituted-alkoxy, or R.sup.3 is combined with R.sup.2 to form a heterocyclic ring; R.sup.8 and R.sup.9 are H, halogen, alkoxy, alkyl, alkoxycarbonyl, nitro, amino, acyl, fluorine substituted-alkyl, fluorine substituted-alkoxy, or aryl group which may have a substituent, or R.sup.8 and R.sup.9 are combined to form an alicyclic ring; R.sup.7 is, where R.sup.8 and R.sup.9 are not combined, H, and, where R.sup.8 and R.sup.9 are combined, H, alkyl which may have a substituent, aryl which may have a substituent, arylcarbonyl which may have a substituent, or a sulfur-containing heterocyclic group; and n is 0 or 1. The new imidazole derivatives are effective particularly as anti-ulcer agents.
本发明涉及一种具有以下结构的新型咪唑衍生物:其中R.sup.1和R.sup.2为H、烷基、环烷基、芳基、芳基烷基或卤素取代的烷基,或者R.sup.1和R.sup.2结合形成杂环;R.sup.3、R.sup.4、R.sup.5和R.sup.6为H、卤素、烷氧基、芳基氧基、烷基、烷氧羰基、硝基、氨基、酰基、氟取代的烷基或氟取代的烷氧基,或者R.sup.3与R.sup.2结合形成杂环;R.sup.8和R.sup.9为H、卤素、烷氧基、烷基、烷氧羰基、硝基、氨基、酰基、氟取代的烷基、氟取代的烷氧基或可能带有取代基的芳基,或者R.sup.8和R.sup.9结合形成脂环;R.sup.7为,在R.sup.8和R.sup.9未结合时为H,在R.sup.8和R.sup.9结合时为H、可能带有取代基的烷基、可能带有取代基的芳基、可能带有取代基的芳基羰基,或者含硫杂环基;n为0或1。这些新型咪唑衍生物特别有效作为抗溃疡药物。
