Imidazole derivatives of the formula ##STR1## wherein AR.sub.1 and AR.sub.2 are independently each phenyl; phenyl substituted by halogen, C.sub.1-4 alkyl, C.sub.1-4 alkoxy or C.sub.2-6 dialkylamino; pyridyl; furyl; or thienyl; with the proviso that AR.sub.1 and AR.sub.2 are not both unsubstituted phenyl; R.sub.1 is hydrogen, alkyl of 1-4 carbon atoms or alkyl of 1-4 carbon atoms substituted by hydroxy, C.sub.1-4 alkoxy or C.sub.1-6 alkanoyloxy; n is 0, 1 or 2; and Z is cyano; alkynyl of 2-6 carbon atoms; cycloalkyl of 3-8 carbon atoms; cycloalkyl of 3-8 carbon atoms substituted by hydroxy, acyloxy, hydroxymethyl or acyloxymethyl, "acyl" in both cases being the acyl group of a hydrocarbon, aliphatic C.sub.1-6 carboxylic acid or of benzoic acid; or alkyl of 1-4 carbon atoms substituted by cyano, phenyl or cycloalkyl of 3-6 carbon atoms; or physiologically acceptable salts thereof with an acid, have valuable pharmacological properties.
咪唑衍生物的化学式为##STR1##其中AR.sub.1和AR.sub.2分别独立为苯基;苯基被卤素、C.sub.1-4烷基、C.sub.1-4烷氧基或C.sub.2-6二烷基氨基取代;吡啶基;呋喃基;或噻吩基;但AR.sub.1和AR.sub.2不能同时为未取代的苯基;R.sub.1为氢、1-4碳原子的烷基或被羟基、C.sub.1-4烷氧基或C.sub.1-6烷酰氧基取代的1-4碳原子的烷基;n为0、1或2;Z为氰基;2-6碳原子的炔基;3-8碳原子的环烷基;3-8碳原子的环烷基,被羟基、酰氧基、羟甲基或酰氧甲基取代,这两种情况下的"酰基"均为烃、脂肪C.sub.1-6羧酸或苯甲酸的酰基;或被氰基、苯基或3-6碳原子的环烷基取代的1-4碳原子的烷基;或其与酸形成的生理上可接受的盐具有有价值的药理学性质。
