• X is —C(R2)═;
• R2 is selected from hydrogen, halogen, cyano, C1-4-alkyl, halo-C1-4-alkyl, cyano-C1-4-alkyl, —OR5, —NR4AR4B, —NR6C(O)OR5, —NR6C(O)R5, —NR6C(O)NR4AR4B, —SO2R5, —SO2NR4AR4B and —NR6S(O)2R5;
• W is a phenyl ring or a 5 or 6-membered heteroaryl ring, either ring being optionally substituted with one or more substituents selected from halogen, cyano, oxo C1-4-alkyl, halo-C1-4-alkyl, cyano-C1-4-alkyl, —OR5, —NR7AR7B, —NR6C(O)OR5, —NR6C(O)R5, —NR6C(O)NR7AR7B, —C(O)NR7AR7B, —C(O)R5, —C(O)OR5, —SO2R5, —SO2NR7AR7B and —NR6S(O)2R5;
• R7A and R7B are independently hydrogen, C1-4-alkyl or halo-C1-4-alkyl.
• V is selected from a bond, —O—, —N(R6)—, —(C═O)—, —CONR6—, —NR6C(O)—, or —C1-4-alkylene-, wherein the C1-4-alkylene group is optionally substituted by halogen, and wherein any one of the carbon atoms of the C1-4-alkylene group may be replaced by —O— or —N(R6)—;
• R3 is selected from hydrogen, —C1-4-alkyl, —C1-4-alkyl-C1-4-alkoxy or a 3-7 membered heterocyclic ring or 3-7 membered cycloalkyl ring, or a 5 or 6-membered heteroaryl ring, any one of the rings being optionally substituted with one or more substituents selected from halogen, oxo, hydroxyl, cyano, C1-4-alkyl, halo-C1-4-alkyl, cyano-C1-4-alkyl, —OR5, —NR4AR4B, —NR6C(O)OR5, —NR6C(O)R5, —NR6C(O)NR4AR4B, —C(O)NR4AR4B, —C(O)R5, —C(O)OR5, —SO2R5, —SO2NR4AR4B and —NR6S(O)2R5
• PROVIDED THAT groups —WVR3 and/or R1 are not:

• and
• R′″ is H, OH, or C1-C6 alkyl;
• and
• FURTHER PROVIDED THAT when —R3 is H, R1 is not a phenyl ring substituted with one —OCH3.
