Patent ID: 8377949

Claim:
A compound of the formula (I): wherein m and n are each independently 0-2 ; R 1 is halogen, trihalomethyl, cyano, amino, hydroxyl, C1-4 alkyl, C1-4 alkoxyl, COR 6 , COOR 6 , CONR 6 R 7 , NR 6 R 7 ; R 2 and R 3 are each independently hydrogen, halogen, trihalomethyl, cyano, amino, hydroxyl, C1-4 alkyl, carbocycle optionally substituted by halogen or C1-4 alkyl, C1-4 alkoxy, COR 6 , COOR 6 , CONR 6 R 7 or NR 6 R 7 , wherein R 2 and R 3 cannot simultaneously be hydrogen; or R 2 and R 3 optionally together cyclize to the C atom to which they are attached to form a carbocyclic or heterocyclic ring optionally substituted by one or more halogen or C1-4 alkyl, C1-4 alkoxyl, trihalomethyl, cyano, amino, hydroxyl, COR 6 , COOR 6 , CONR 6 R 7 or NR 6 R 7 ; R 4 and R 5 are each independently hydrogen, trihalomethyl, cyano, amino, hydroxyl, C1-4 alkyl, methoxy, COR 6 , COOR 6 , CONR 6 R 7 or NR 6 R 7 ; Ar is a mono- or poly-substituted or unsubstituted fused heteroaromatic group having 7-10 carbon atoms and containing one or more hetero atoms selected from the group consisting of an oxygen atom, a nitrogen atom and a sulfur atom in its ring(s); each substituent on said aromatic or heteroaromatic groups is selected from a halogen, hydroxyl, nitro, cyano, a linear or branched C1-6 alkyl group, a linear or branched C1-6 alkoxy (including the case in which two adjacent groups form an acetal bond), a linear or branched C1-6 alkylthio, a linear or branched C1-6 alkylsulfonyl group, phenylsulfonyl, a linear or branched C1-6 acyl group, a linear or branched C1-6 acylamino, trihalomethyl, trihalomethoxy, phenyl, COOR 6 , CONR 6 R 7 , SO 2 NR 6 R 7 , NR 6 R 7 and phenoxy group that may be substituted by one or more halogen atoms; R 6 , R 7 each independently represent a hydrogen atom or linear or branched alkyl group having 1-6 carbon atoms, or R 6 and R 7 optionally together represent —CH 2 —CH 2 —, —CH 2 —CH 2 —CH 2 — or —CH 2 —CH 2 —CH 2 and cyclize to the N atom to which they are attached to form a heterocycle ring optionally substituted by one or more C1-4 alkyl; with the proviso that Ar is not an optionally substituted benzimidazolyl ring; or a pharmaceutically acceptable salt thereof.
