Compounds of formula (I)
wherein: X is CH or CH—R2; R1 is C1-C6 linear or branched alkyl or C1-C6 linear or branched alkenyl; R2 is hydrogen, C1-C6 linear or branched alkyl or C1-C6 linear or branched alkenyl, C6-C14 aryl or C6-C14 aryl(C1-C6) linear or branched alkyl or C6-C14 aryl(C1-C6) linear or branched alkenyl, with the aryl group optionally substituted by one or more substituents, either the same or different, selected from the group consisting of halogen, hydroxy, C1-C6 alkoxy linear or branched or C1-C6 alkenyloxy linear or branched, amino, optionally mono- or disubstituted with C1-C6 linear or branched alkyl; R3 is NH2, or NHR4; R4 is C1-C6 alkyl or C1-C6 hydroxyalkyl, C1-C3 alkoxyalkyl, amino(C1-C6)alkyl, where the amino group is optionally substituted with one or two C1-C3 linear or branched alkyl groups, or with one or two C2-C3 alkenyl groups C6-C14 aryl or C6-C14 aryl(C1-C6)alkyl, with the aryl group optionally substituted by one or more substituents, either the same or different, selected from the group consisting by halogen, hydroxy, C1-C6 alkoxy linear or branched or C1-C6 alkenyloxy linear or branched, amino, mono- or di-substituted with C1-C6 alkyl linear or branched or C1-C6 alkenyl linear or branched; and their pharmaceutically acceptable salts. These compounds are antagonists of the adenosine A2a receptor and useful as medicaments, in particular for the treatment of Parkinson's disease.
