Compounds of formula (I), wherein R is a hydrogen atom or an OY group; R1 is a hydrogen atom or an OY' group; R2 is a hydrogen atom or an OY" group; provided that at least one among R, R1 and R2 is hydrogen but R, R1 and R2 are not contemporaneously hydrogen atoms and R1 and R2 are not contemporaneously OY' or OY" groups respectively; m is an integer selected between 1 and 2; n is an integer comprised among 3 and 8; p is an integer comprised among 2 and 4; R3 is a hydrogen atom or a C1-C4 alkyl; R4 is a phenyl optionally substituted by halogen atoms, C1-C3 alkyl or alkoxy groups or a 5- or 6-membered heteroaryl containing one or more heteroatoms selected among oxygen, nitrogen and sulphur, optionally substituted by halogen atoms, hydroxy groups, C1-C3 alkyl or alkoxy groups; X is CH2, NH, S,SO,SO2,CO,CF2,O and, when R4 is a 5- or 6-membered heteroaryl, X can be also a single bond; and their pharmaceutically acceptable salts are described. The compounds of formula (I) are useful in the treatment of arterial hypertension and heart failure, of renal insufficiency, of peripheral arteriopathies and of cerebrovascular insufficiencies. |
