Abstract: The present invention relates to compounds of general formula (I), tautomers, stereoisomers, N-oxides, pharmaceutically acceptable salts and pro-drug thereof, to processes for their preparation, to pharmaceutical compositions containing such compounds and to their use in therapy: wherein: a dashed line indicates an optional bond; X represents: a 5- or 6-membered, unsaturated heterocyclic group optionally substituted by one or more (e.g. 1, 2 or 3) substituents independently selected from halogen (i.e. F, Cl, Br, I), C1-6 alkyl (e.g. C1-3 alkyl), C1-6 haloalkyl (e.g. C1-3 haloalkyl), C1-6 alkoxy (e.g. C1-3 alkoxy), -CN, -NO2, -N(R)2, and -SO2R (where each R is independently H or C1-6 alkyl, e.g. H or C1-3 alkyl); a C3-5 cycloalkyl group optionally substituted by one or more (e.g. 1 or 2) substituents independently selected from C1-6 alkyl (preferably C1-3 alkyl), C1-6 haloalkyl (e.g. C1-3 haloalkyl), and C1-6 alkoxy (e.g. C1-3 alkoxy); or an aryl group optionally substituted by one or more (e.g. 1, 2 or 3) substituents independently selected from halogen (i.e. F, Cl, Br, I), C1-6 alkyl (e.g. C1-3 alkyl), C1-6 haloalkyl (e.g. C1-3 haloalkyl), and C1-6 alkoxy (e.g. C1-3 alkoxy); Y represents: an aryl or heteroaryl group optionally substituted by one or more (e.g. 1, 2 or 3) substituents independently selected from halogen (i.e. F, Cl, Br, I), C1-6 alkyl (e.g. C1-3 alkyl), C1-6 haloalkyl (e.g. C1-3 haloalkyl), and C1-6 alkoxy (e.g. C1-3 alkoxy); a 5- or 6-membered, saturated heterocyclic group optionally substituted by one or more (e.g. 1, 2 or 3) substituents independently selected from C1-6 alkyl (preferably C1-3 alkyl), C1-6 haloalkyl (e.g. C1-3 haloalkyl), and C1-6 alkoxy (e.g. C1-3 alkoxy); or a C3-6 cycloalkyl group optionally substituted by one or more (e.g. 1 or 2) substituents independently selected from C1-6 alkyl (preferably C1-3 alkyl), C1-6 haloalkyl (e.g. C1-3 haloalkyl), and C1-6 alkoxy (e.g. C1-3 alkoxy); and Z represents: an aryl group optionally substituted by one or more (e.g. 1, 2 or 3) substituents independently selected from halogen (i.e. F, Cl, Br, I), C1-6 alkyl (e.g. C1-3 alkyl), C1-6 haloalkyl (e.g. C1-3 haloalkyl), C1-6 alkoxy (e.g. C1-3 alkoxy), -CN, -NO2, -OH, -N(R' )2 (where each R1 is independently H or C1-6 alkyl, e.g. H or C1-3 alkyl), -SO2R2 (where R2 is H or C1-6 alkyl, e.g. H or C1-3 alkyl), -SO2N(R3)2 (where each R3 is independently H or C1-6 alkyl, e.g. H or C1-3 alkyl), and -C(0)N(R4)2 (where each R4 is independently H or C1-6 alkyl, e.g. H or C1-3 alkyl, or wherein both R4 groups, together with the intervening nitrogen atom, form a 3 to 6 membered saturated heterocyclic ring); or an unsaturated, 5- to 10-membered mono- or bicyclic heterocyclic group optionally substituted by one or more (e.g. 1, 2 or 3) substituents independently selected from halogen (i.e. F, Cl, Br, I), C1-6 alkyl (e.g. C1-3 alkyl), C1-6 haloalkyl (e.g. C1-3 haloalkyl), C1-6 alkoxy (e.g. C1-3 alkoxy), -CN, -NO2, -OH, -N(R')2 (where each R1 is independently H or C1-6 alkyl, e.g. H or C1-3 alkyl), -SO2R2 (where R2 is H or C1-6 alkyl, e.g. H or C1-3 alkyl), -SO2N(R3)2 (where each R3 is independently H or C1-6 alkyl, e.g. H or C1-3 alkyl), and -C(O)N(R4)2 (where each R4 is independently H or C1-6 alkyl, e.g. H or C1-3 alkyl, or wherein both R4 groups, together with the intervening nitrogen atom, form a 3 to 6 membered saturated heterocyclic ring); with the proviso: that when the compound is other than an N-oxide of formula (I), Z must be substituted by at least one substituent selected from -OH, -N(R3)2, -SO2N(R3)2 and -C(O)N(R4)2, preferably by at least one substituent selected from -OH, -SO2N(R3)2 and -C(O)N(R4)2. These compounds find particular use in the treatment and/or prevention of a disease or disorder responsive to inhibition of tankyrase 1 and/or 2, for example a disorder which is mediated by tankyrase 1 and/or 2 such as cancer.
