Patent ID: 7662995

Claim:
A compound of formula (I): wherein: R and R 1 together with the carbon atom to which they are linked form a ring which contains 3 to 6 carbon atoms; G is a —COOH group; R 2 is H or a halogen selected from the group consisting of F, Cl, Br, and I; Ar is a group of formula wherein R 3 represents one or more groups independently selected from: a halogen selected from the group consisting of F, Cl, Br, and I; CF 3 ; C 3 -C 8 cycloalkyl optionally substituted with one or more C 1 -C 4 alkyl groups, oxo groups, or a combination thereof; phenyl optionally substituted with one or more of the following groups: halogen; CF 3 ; OCF 3 ; OH; a linear or a branched C 1 -C 4 alkyl; a saturated heterocycle with at least 4 carbon atoms and at least 1 heteroatom; a C 3 -C 8 cycloalkyl in turn optionally substituted with one or more of the following groups: a linear or a branched C 1 -C 4 alkyl, CF 3 or OH; OR 4 or NHCOR 4 , wherein R 4 is CF 3 , a linear or a branched C 2 -C 6 alkenyl or alkynyl; a benzyl; a phenyl optionally substituted with one or more of the following groups: halogen, CF 3 , OCF 3 , OH, a linear or a branched C 1 -C 4 alkyl; a saturated heterocycle with at least 4 carbon atoms and at least 1 heteroatom; a C 3 -C 8 cycloalkyl in turn optionally substituted with one or more of the following groups: a linear or a branched C 1 -C 4 alkyl, CF 3 or OH; otherwise Ar is a heterocyclic ring, which may optionally be substituted with one or more R 3 groups, selected from the group consisting of thiophene, benzothiophene, dibenzothiophene; or a pharmaceutically acceptable salt thereof.
