Claim:
A compound of the general formula (I) wherein: W is aryl or heteroaryl: a is 0, 1, 2, or 3; R and R′ are the same or different and, independently from each other, is: hydrogen; halogen; (C1-C3)alkoxy; (C1-C2)haloalkoxy; (C1-C2)haloalkyl; NR 1 R 2 ; CN; SO 2 NH 2 ; or optionally substituted (C1-C6)alkyl, aryl or heteroaryl; R″ is: halogen; (C1-C3)alkyl; (C1-C3)alkoxy; (C1-C3)alkoxyalkyl; (C1-C2)haloalkoxy; (C1-C2)haloalkyl; NR 3 R 4 ; or (CH 2 ) n —X—(CH 2 ) m -Q, wherein: n, in independently, are 0, 1, or 2; X is a direct bond; O; S; NH; or N(C1-C3)alkyl; Q is an optionally substituted aryl, heteroaryl, heterocycloalkyl or cycloalkyl; R 1 , R 2 , R 3 , and R 4 are the same or different and, independently from each other, is a hydrogen atom; a (C1-C3)alkyl or, taken together with the nitrogen atom to which they are attached, R 1 —N—R 2 and R 3 —N—R 4 may form a heterocyclic ring of formula: wherein: R 5 is a hydrogen atom or a (C1-C3)alkyl group; with the proviso that: when W is phenyl, a is 1, 2 or 3; when W is phenyl and R is hydrogen, R″ is other than chlorine, methyl, isopropyl, CF 3 or NH 2 ; when W is indazol-5-yl or pyrid-2-yl, R is other than hydrogen, or (C1-C3)alkoxy: as well as its tautomers, racemic forms, enantiomers, diastereomers, epimers, mixtures thereof, prodrugs and the pharmaceutically acceptable salts thereof.
