Claims10
A compound of the formula (I):
- wherein A and B are independently CR12 or N;
- D and E are each independently CR9 or N;
- R1 represents (C1-C6)alkyl;
- R2 represents hydrogen, halogen, hydroxy, (C1-C6) alkyl, halo(C1-C6) alkyl, hydroxy(C1-C6)alkyl, (C1-C6)alkoxy or (C1-C6)alkoxy-(C1-C6)alkyl;
- R3, R4, R5, R6, R10 and R11 each independently represent hydrogen, halogen, (C1-C6)alkyl, halo(C1-C6)alkyl, (C1-C6)alkoxy, hydroxy(C1-C6)alkyl or (C1-C6)alkoxy-(C1-C6)alkyl;
- or R3 and R4 are taken together with the carbon atom to which they are attached to form a 3- to 7-membered carbocyclic ring or heterocyclic ring in which one or two non-adjacent carbon atoms are optionally replaced by an oxygen atom, a sulfur atom or NH;
- R7 and R9 each independently represent hydrogen, halogen, (C1-C6)alkyl, halo(C1-C6)alkyl, hydroxy(C1-C6)alkyl, (C1-C6)alkoxy, hydroxyl(C1-C6)alkoxy, (C1-C6)alkoxy-(C1-C6)alkyl, (C1-C6)alkoxy-(C1-C6)alkoxy, (C1-C6)alkylthio, (C1-C6)alkylsulfinyl, (C1-C6)alkylsulfonyl, NH2, [(C1-C6)alkyl]NH—, [(C1-C6)alkyl]2N—, H2N—(C1-C6)alkoxy, (C1-C6)alkyl-NH—(C1-C6)alkoxy, [(C1-C6)alkyl]2N(C1-C6)alkoxy;
- H2N—(C1-C6)alkoxy-(C1-C6)alkyl, (C1-C6)alkyl-NH—(C1-C6)alkoxy-(C1-C6)alkyl, [(C1-C6)alkyl]2N(C1-C6)alkoxy-(C1-C6)alkyl or 5- or 6-membered heterocyclic ring containing at least one nitrogen atom;
- R8 represents halogen, (C1-C6)alkyl, halo(C1-C6)alkyl, hydroxy(C1-C6)alkyl, (C1-C6)alkoxy, hydroxy(C1-C6)alkoxy, (C1-C6)alkoxy-(C1-C6)alkyl, (C1-C6)alkoxy-(C1-C6)alkoxy, halo(C1-C6)alkylsulfonyl, halo(C1-C6)alkylsulfinyl, halo(C1-C6)alkoxy, halo(C1-C6)alkylthio, [(C1-C6)alkyl]NH— or [(C1-C6)alkyl]2N—;
- or R7 and R8, when E is CR9, are taken together with the carbon atoms to which they are attached form a 5-8 membered carbocyclic or heterocyclic ring, in which one or two non-adjacent carbon atoms are optionally replaced by oxygen, sulfur, N or NH groups, wherein the carbocyclic ring or the heterocyclic ring is unsubstituted or substituted with one or more substituents each independently selected from the group consisting of hydroxy, (C1-C6)alkyl, (C1-C6)alkoxy and hydroxy(C1-C6)alkyl;
- and R12 represents hydrogen, halogen, (C1-C6)alkyl or hydroxy(C1-C6)alkyl;
- with the proviso that one and only one A, B, D, or E is N;
- or a pharmaceutically acceptable salt thereof.
