Claim:
A compound of formula (I): and pharmaceutically acceptable salts thereof, wherein Q, V and Z are each selected from the group consisting of 1) —CH, and 2) N; X and Y are linked together to form a fused ring moiety selected from the group consisting of W is selected from the group consisting of 1) —CH, and 2) —N; R 1 is optionally present at one or more of the ring carbon atoms, and is selected from the group consisting of (1) —C 1-6 alkyl, (2) —O—C 1-6 alkyl, or (3) halogen; R 2 is selected from the group consisting of (1) aryl, (2) a heteroaryl group which is an aromatic cyclic group, having from five to twelve ring atoms, said ring atoms selected from C, O, N or S, at least one of which is O,N or S, (3) halogen, wherein said aryl or heteroaryl is optionally substituted with one or more (a) halogen, (b) hydroxy, (c)—O—C 1-6 alkyl, (d)—C 1-6 alkyl, (e) cyano, (f) —NR A R B , wherein R A and R B are selected from the group consisting of (i) hydrogen, or (ii)—C 1-6 alkyl, or R A and R B are linked together with the nitrogen to which they are both attached to form a 2-6 membered carbocyclic ring, wherein one or two of the ring carbon atoms is replaced by a nitrogen, oxygen or sulfur, and the carbocyclic is optionally substituted with one or more C 1-6 alkyl, (g)—C(═O)—R C , wherein R C is selected from the group consisting of (i) hydrogen, or (ii) —C 1-6 alkyl, or (h) —S(O) n —R C ; R 3 is selected from the group consisting of (1) aryl, (2) a heteroaryl group, which is an aromatic cyclic group, having from five to twelve ring atoms, said ring atoms selected from C, O, N or S, at least one of which is O, N or S, (3)—C 5-10 cycloalkyl, or (4) a heterocyclic group, which is a nonaromatic cyclic group, having from five to twelve ring atoms, said ring atoms selected from C, O, N or S, at least one of which is O, N or S, wherein said aryl, heteroaryl cycloalkyl or heterocyclic group is optionally substituted with one or more (a) halogen, (b) hydroxy, (c) —O—C 1-6 alkyl, or (d) —C 1-6 alkyl; n is 0, 1 or 2.
