Patent ID: 7470688

Claim:
A compound of the formula (I): wherein: A and B together represent an optionally substituted, fused aromatic ring; where Y 3 is selected from CH and CF; and R D is: wherein R N1 is selected from H and optionally substituted C 1-10 alkyl; X is selected from a single bond, NR N2 , CR C3 R C4 and C═O; R N2 is selected from H and optionally substituted C 1-10 alkyl; R C3 and R C4 are independently selected from H, R, C(═O)OR, where R is optionally substituted C 1-10 alkyl, optionally substituted C 5-20 aryl or optionally substituted C 3-20 heterocyclyl; Y is selected from NR N3 and CR C1 R C2 ; R C1 and R C2 are independently selected from H, R, C(=O)OR, where R is optionally substituted C 1-10 alkyl, optionally substituted C 5-20 aryl or optionally substituted C 3-20 heterocyclyl; R C1 and R C2 together with the carbon atom to which they are attached may form an optionally substituted spiro-fused C 5-7 carbocylic or heterocyclic ring; and when X is a single bond R N1 and R C2 may together with the N and C atoms to which they are bound, form an optionally substituted C 5-7 heterocylic ring; and when X is CR C3 R C4 , R C2 and R C4 may together form an additional bond, such that there is a double bond between the atoms substituted by R C1 and R C3 .
