Patent ID: 8258308

Claim:
A compound of formula (I), wherein one of the G 1 groups is chosen from a nitrogen atom and a CR c group and the other G 1 group represents a CR c group; G 2 represents a CR d group; R 1 is chosen from hydrogen atoms, halogen atoms, C 1-4 alkyl groups, which may be optionally substituted by 1, 2 or 3 substituents chosen from halogen atoms and hydroxy groups, and C 3-8 cycloalkyl groups which may be optionally substituted by 1, 2 or 3 substituents chosen from halogen atoms and hydroxy groups; R 2 is chosen from hydrogen atoms, halogen atoms, hydroxyl groups, C 1-4 alkyl groups, which may be optionally substituted by 1, 2 or 3 substituents chosen from halogen atoms and hydroxy groups, C 1-4 alkoxy groups, which may be optionally substituted by 1, 2 or 3 substituents chosen from halogen atoms and hydroxy groups, and C 3-8 cycloalkyl groups, which may be optionally substituted by 1, 2 or 3 substituents chosen from halogen atoms and hydroxy groups; R a , R b and R c are each independently chosen from hydrogen atoms, halogen atoms, C 1-4 alkyl groups, which may be optionally substituted by 1, 2 or 3 substituents chosen from halogen atoms and hydroxy groups, and C 1-4 alkoxy groups, which may be optionally substituted by 1, 2 or 3 substituents chosen from halogen atoms and hydroxy groups; R d is chosen from hydroxy groups, C 1-3 alkoxy groups, 2,2,2-trifluoroethoxy groups and C 3-4 cycloalkoxy groups; one of the groups G 3 and G 4 is a nitrogen atom and the other is a CH group; and M is a hydrogen atom or an pharmaceutically acceptable cation; with the proviso that, when at least one of the groups R a and R b represent a hydrogen atom, then R d is chosen from C 1-3 alkoxy groups, which may be optionally substituted by 1, 2 or 3 substituents chosen from halogen atoms and hydroxy groups, and C 3-4 cycloalkoxy groups, which may be optionally substituted by 1, 2 or 3 substituents chosen from halogen atoms and hydroxy groups; or a pharmaceutically acceptable salt or N-oxide thereof.
