<p>The present invention provides compounds of the general formula: <IMAGE> (I) wherein Ar is a substituted or unsubstituted aromatic or heteroaromatic radical, A is a straight-chained or branched alkylene chain containing up to 8 carbon atoms, a -CH2- group of which can be replaced by a cycloalkylene radical containing 3 to 7 carbon atoms, B is a straight-chained mono- or bicyclic, optionally branched, saturated or unsaturated alkylene chain containing up to 12 carbon atoms, a -CH2- group of which can be replaced by a cycloalkylene radical containing 3 to 7 carbon atoms and/or up to two -CH2- groups of which can be replaced by an oxygen or a sulphur atom or by an -S(=O) or -S(=O)2 group, X is a valency bond, an oxygen atom or an -NR1 group, in which R1 is a hydrogen atom or a straight-chained or branched, saturated or unsaturated alkyl or nitroxyalkyl radical containing up to 6 carbon atoms or R1, together with the nitrogen atom of the -NR1- group and a -CH2- group of the chain B, can form a heteroaliphatic ring containing 4 to 6 carbon atoms and n is 1, 2 or 3; and the physiologically acceptable salts thereof. The present invention also provides processes for the preparation of these compounds and pharmaceutical compositions containing them. Furthermore, the present invention is concerned with the use of these compounds for the treatment and/or prophylaxis of heart and circulatory diseases.</p> |
