New substituted 1H-imidazoles and their salts, processes for the preparation thereof and pharmaceutical compositions. These compounds have the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.5 =hydrogen or C.sub.1 -C.sub.4 -alkyl; R.sub.4 =hydrogen, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkoxy; Y.sub.1 =hydrogen and Y.sub.2 =OZ.sub.2 or the reverse; Z.sub.1 =Z.sub.2 =hydrogen or C.sub.1 -C.sub.4 -alkyl or Z.sub.1 and Z.sub.2 =--CH.sub.2 -- or --C(CH.sub.3).sub.2 --. These compounds are prepared either by reducing a corresponding imidazole compound having a hydroxyl or alkoxy group on the methyl bridge between the imidazole and phenyl rings, or by hydrolyzing a 4-[[2,2-dimethyl-4H-1,3-benzodioxin-6(or 8)-yl]methyl]-1H-imidazole, or yet by reducing an alkyl 3-[(1H-imidazol-4-yl)methyl]-2-hydroxybenzoate. These compounds have cardiac, cerebral and tissular anti-ischemic activities.
新型取代1H-咪唑及其盐类、制备方法及药物组合物。这些化合物具有如下通式##STR1##其中R1、R2、R3和R5为氢或C1-C4烷基;R4为氢、C1-C4烷基或C1-C4烷氧基;Y1为氢且Y2为OZ2或相反;Z1=Z2为氢或C1-C4烷基,或者Z1和Z2为--CH2--或--C(CH3)2--。这些化合物可通过还原具有咪唑环与苯环之间甲基桥上羟基或烷氧基的相应咪唑化合物来制备,或通过水解4-[[2,2-二甲基-4H-1,3-苯并二氧戊环-6(或8)-基]甲基]-1H-咪唑,或通过还原烷基3-[(1H-咪唑-4-基)甲基]-2-羟基苯甲酸酯来制备。这些化合物具有心脏、脑部及组织抗缺血活性。
