Claim:
A compound of formula (I) wherein, R a , R b and R d are independently selected from hydrogen, hydroxy, halogen, cyano, nitro, —COR 1 , —COOR 1 , —CONH 2 , —NR 1 R 2 , —C 1 -C 8 alkyl, halo-C 1 -C 8 alkyl and —C 1 -C 8 alkoxy; R c is halogen or heteroaryl; R e is hydrogen, —C 1 -C 8 alkyl, —C 6 -C 14 aryl or heteroaryl; Q is —SO 2 , —C(O)NR 1 or —C(S)NR 1 ; R f is —C 1 -C 8 alkyl, —(CR 1 R 2 ) p —C 3 -C 8 cycloalkyl, —(CR 1 R 2 ) p —C 6 -C 14 aryl, —(CR 1 R 2 ) p heterocyclyl, —(CR 1 R 2 ) p heteroaryl, —C 3 -C 8 cycloalkyl, —C 6 -C 14 aryl, heteroaryl or heterocyclyl; R 1 and R 2 are independently selected from hydrogen and lower alkyl; p is independently an integer from 1 to 3; with the proviso that when Q is —SO 2 , then R c is not halogen; wherein each of the above alkyl, haloalkyl, alkoxy, cycloalkyl, aryl, heteroaryl and heterocyclyl are unsubstituted or substituted with one or more of the same or different groups selected from halogen, hydroxy, carbonyl, carboxy, ester, ether, acyl, acyloxy, cyano, amino, amide, imino, alkylthio, thioester, sulfonyl, nitro, —C 1 -C 6 alkyl, halo-C 1 -C 6 alkyl, halo-C 1 -C 6 alkoxy, —C 1 -C 6 alkoxy, haloalkoxy, —C 3 -C 8 cycloalkyl, —(CR 1 R 2 ) p -aryl, —C 6 -C 10 aryl, —NHCOMe, —S(O) 2 Me, aryloxy, heterocyclyl and heteroaryl; or a stereoisomer, tautomer, N-oxide or a pharmaceutically acceptable salt thereof.
