摘要 |
The invention concerns substituted 3-amino-1-arylalkyl-benzazepin-2-ones of general formula (I) in which Ar is aryl; X is C1-C2 alkylene or a single bond; R1 is hydrogen, lower alkyl, aryl(lower alkyl) or acyl; R2 is lower alkyl, hydroxy(lower alkyl), (lower alkoxy)(lower alkyl), aryl(lower alkoxy)(lower alkyl), aryl(lower alkyl) or (C3-C7 cycloalkyl)(lower alkyl); R3 is a carboxylic group, 5-tetrazolyl, PO2H2, PO3H2 or SO3H2 (lower alkoxy)carbonyl, (lower alkoxy)(lower alkoxy)carbonyl, aryl(lower alkoxy)carbonyl, aryloxycarbonyl, carbamoyl, carbamoyl which is (i) mono-substituted by hydroxy, (lower alkyl)sulphonyl, halo(lower alkyl)sulphonyl or arylsulphonyl, (ii) mono-substituted or independently disubstituted by lower alkyl, lower alkenyl, lower alkinyl or phenyl(lower alkyl) or (iii) disubstituted by lower alkylene or (lower alkylene)-X1-(lower alkylene), X1 being O, S or NH; the ring A is unsubstituted or singly or multiply substituted by substituents selected from the group comprising lower alkyl, aryl(lower alkyl), (lower alkoxy)(lower alkyl), lower alkoxy, (lower alkoxy)(lower alkoxy), aryl(lower alkoxy, C3-C7 cycloalkyl, (C3-C7 cycloalkyl)(lower alkyl), nitro, halogen, trifluoromethyl, amino or amino which is mono-substituted or independently disubstituted by lower alkyl, aryl(lower alkyl) or aryl or disubstituted by lower alkylene or (lower alkylene)-oxy-(lower alkylene); or a salt thereof. The invention also concerns methods of preparing these compounds, their use, and pharmaceutical preparations containing compounds of formula (I) or pharmaceutically usable salts thereof. |
