摘要

Compounds of formula (I) wherein R is a biphenyl group optionally substituted by one or more substituents, the same or different, selected among halogen atoms, nitro groups, hydroxy groups, alkoxy, alkyl, thioalkyl or alkoxycarbonyl groups having from 1 to 6 carbon atoms in the alkyl moiety, C1-C3 alkyl groups containing one or more fluorine atoms, carboxy groups, amino or aminocarbonyl groups, acylamino groups, aminosulphonyl groups, mono- or di-alkylamino groups having from 1 to 6 carbon atoms in the alkyl moiety, mono- or di-alkylaminocarbonyl groups having from 1 to 6 carbon atoms in the alkyl moiety; R1 is a hydrogen atom, a straigth or branched C1-C6 alkyl or an arylalkyl group having from 1 to 6 carbon atoms in the alkyl moiety wherein the aryl is a phenyl, a biphenyl, a naphthyl or a 5- or 6-membered aromatic heterocycle with one or two heteroatoms selected among nitrogen, oxygen and sulphur, optionally substituted by one or more substituents, the same or different, selected among halogen atoms, hydroxy groups, alkoxy, alkyl, thioalkyl or alkoxycarbonyl groups having from 1 to 6 carbon atoms in the alkyl moiety, C1-C3 alkyl groups containing one or more fluorine atoms, carboxy groups, nitro groups, amino or aminocarbonyl groups, acylamino groups, aminosulphonyl groups, mono- or di-alkylamino groups having from 1 to 6 carbon atoms in the alkyl moiety, mono- or di-alkylaminocarbonyl groups having from 1 to 6 carbon atoms in the alkyl moiety; R2 is a straigth or branched C1-C6 alkyl optionally substituted by one or more substituents selected among amino, mono- or di-(C1-C6)alkylamino or aminocarbonyl groups, mono or di-(C1-C6)-alkylaminocarbonyl groups, an arylalkyl, an arylcarbonylaminoalkyl, an arylaminocarbonylalkyl or an arylalkylaminocarbonylalkyl group having from 1 to 6 carbon atoms in the alkyl moiety, the aryl being optionally substituted by one or more substituents, the same or different, selected among halogen atoms, hydroxy groups, alkoxy, alkyl, thioalkyl or alkoxycarbonyl groups having from 1 to 6 carbon atoms in the alkyl moiety, C1-C3 alkyl groups containing one or more fluorine atoms, carboxy groups, nitro groups, amino or aminocarbonyl groups, acylamino groups, aminosulphonyl groups, mono- or di-alkylamino groups having from 1 to 6 carbon atoms in the alkyl moiety, mono- or di-alkylaminocarbonyl groups having from 1 to 6 carbon atoms in the alkyl moiety; X is a single bond or an -N(R3)- group wherein R3 is a hydrogen atom or a straight or C1-C4 alkyl group; the carbon atoms marked with an asterisk are asymmetric carbon atoms; and their pharmaceutically acceptable salts, are described. The compounds of formula (I) are endowed with a mixed ACE-inhibitory and NEP-inhibitory activity and are useful in the treatment of cardiovascular diseases.
