The present invention relates to a compound of formula (I), or a pharmaceutically acceptable salt or N-oxide thereof: wherein:. L represents a direct bond or a -S(O)2- group, • n is an integer having a value from 0 to 2, • R1 represents a pyridyl group or an imidazo[1,2-α]pyridinyl group, wherein the pyridyl group is substituted with one or more substituents selected from halogen atoms, a hydroxy group, a C1-4 alkyl group and a C1-4 alkoxy group, or • R1 represents a group of formula: wherein:. Ra and Rb independently represent a hydrogen atom, halogen atom or a linear or branched C1-4, alkyl group,. Rc represents a hydroxy group, a linear or branched C1-4 alkyl group or C1-4 alkoxy group wherein the alkyl and the alkoxy groups independently are optionally substituted with one or more substituents selected from hydroxy group, cyano group and-NR'R" groups and wherein R' represents a hydrogen atom or a linear or branched C1-4 alkyl group, R" represents a hydrogen atom or a linear or branched C1-4 alkyl group optionally substituted with a hydroxycarbonyl group; or R' and R" together with the nitrogen atom to which they are attached form a 4 to 6 membered, saturated heterocyclic ring optionally substituted with a hydroxycarbonyl group.. R2 represents a pyridyl group, a C3-6 cycloalkyl group or a phenyl group which is optionally substituted with one or more substituents selected from halogen atoms, cyano group, and C1-4 alkoxy group; and. R3 represents a C3-6 cycloalkyl group, a C3-6 cycloalkyl-C1-2 alkyl group or a linear or branched C2-4 alkyl group optionally substituted with one or more substituents selected from halogen atoms and C1-2 alkoxy group.
