The invention relates to compounds having the formula: <IMAGE> (I) in which: the substituents R1, R2 and R3 represent independently from each other a hydrogen atom, a halogen atom, a trifluoromethyl radical, a saturated or unsaturated straight- or branched-chain C1-6 alkyl radical, a C1-6 alkoxy radical the alkyl moiety of which may be saturated or unsaturated and straight- or branched-chained, a benzyloxy radical or a hydroxy radical; the substituents R5, R6 and R7 represent independently from each other a hydrogen atom, a halogen atom, a trifluoromethyl radical, a straight- or branched-chain saturated or unsaturated C1-6 alkyl radical, a C1-6 alkoxy radical the alkyl moiety of which may be saturated or unsaturated and straight- or branched-chained, or a hydroxy radical; the substituent R4 represents a hydrogen atom, a C1-6 alkyl radical or a hydroxy radical, m and n represent independently a number equal to 0, 1 or 2, X represents an oxygen atom, a sulfur atom or a single bond, and their pharmaceutically acceptable acid addition salts. These compounds are therapeutically useful for the control of the cardiovascular system. |
