The invention provides a compound for use as a protein kinase B inhibitor, the compound being a compound of the formula (I) or salts, solvates, tautomers or N-oxides thereof, wherein T is N or CR; J-Jis N&#x2550;C(R), (R)C&#x2550;N, (R)N&#x2014;C(O), (R)C&#x2014;C(O), N&#x2550;N or (R)C&#x2550;C(R); E is a monocyclic carbocyclic or heterocyclic group of 5 or 6 ring members, the heterocyclic group containing up to 3 heteroatoms selected from O, N and S; Qis a bond or a saturated Chydrocarbon linker group, one of the carbon atoms in the linker group being optionally be replaced by an oxygen or nitrogen atom, or an adjacent pair of carbon atoms may be replaced by CONRor NRCO where Ris hydrogen or methyl, or Ris a Calkylene chain linked to R or a carbon atom of Qto form a cyclic moiety; and wherein the carbon atoms of the linker group Qmay optionally bear one or more substituents selected from fluorine and hydroxy; Qis a bond or a saturated hydrocarbon linker group containing from 1 to 3 carbon atoms, wherein one of the carbon atoms in the linker group may optionally be replaced by an oxygen or nitrogen atom; and wherein the carbon atoms of the linker group may optionally bear one or more substituents selected from fluorine and hydroxy, provided that the hydroxy group when present is not located at a carbon atom a with respect to the G group; and provided that when E is aryl or heteroaryl, then Qis other than a bond; G is hydrogen, NRR, OH or SH provided that when E is aryl or heteroaryl and Qis a bond, then G is hydrogen; Ris hydrogen or an aryl or heteroaryl group, with the proviso that when Ris hydrogen and G is NRR, then Q is a bond; and R, R, R, Rand Rare as defined in the claims. 

Ortho-condensed pyridine and pyrimidine derivatives (e.g., purines) as protein

The invention provides a compound for use as a protein kinase B inhibitor, the compound being a compound of the formula (I) or salts, solvates, tautomers or N-oxides thereof, wherein T is N or CR; J-Jis N&#x2550;C(R), (R)C&#x2550;N, (R)N&#x2014;C(O), (R)C&#x2014;C(O), N&#x2550;N or (R)C&#x2550;C(R); E is a monocyclic carbocyclic or heterocyclic group of 5 or 6 ring members, the heterocyclic group containing up to 3 heteroatoms selected from O, N and S; Qis a bond or a saturated Chydrocarbon linker group, one of the carbon atoms in the linker group being optionally be replaced by an oxygen or nitrogen atom, or an adjacent pair of carbon atoms may be replaced by CONRor NRCO where Ris hydrogen or methyl, or Ris a Calkylene chain linked to Ror a carbon atom of Qto form a cyclic moiety; and wherein the carbon atoms of the linker group Qmay optionally bear one or more substituents selected from fluorine and hydroxy; Qis a bond or a saturated hydrocarbon linker group containing from 1 to 3 carbon atoms, wherein one of the carbon atoms in the linker group may optionally be replaced by an oxygen or nitrogen atom; and wherein the carbon atoms of the linker group may optionally bear one or more substituents selected from fluorine and hydroxy, provided that the hydroxy group when present is not located at a carbon atom a with respect to the G group; and provided that when E is aryl or heteroaryl, then Qis other than a bond; G is hydrogen, NRR, OH or SH provided that when E is aryl or heteroaryl and Qis a bond, then G is hydrogen; Ris hydrogen or an aryl or heteroaryl group, with the proviso that when Ris hydrogen and G is NRR, then Qis a bond; and R, R, R, Rand Rare as defined in the claims. 

Ortho-condensed pyridine and pyrimidine derivatives (e.g., purines) as protein kinases inhibitors

The invention provides a compound for use as a protein kinase B inhibitor, the compound being a compound of the formula (Ic) or salts, tautomers or N-oxides thereof. 

The present invention pertains generally to the field of therapeutic compounds, and more specifically to certain oxy phenyl aryl compounds (referred to herein as OPA compounds), as described herein, which, inter alia, inhibit Checkpoint Kinase 2 (CHK2) kinase function. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit CHK2 kinase function, and in the treatment of diseases and conditions that are mediated by CHK2, that are ameliorated by the inhibition of CHK2 kinase function, etc., including proliferative conditions such as cancer, etc., optionally in combination with another agent, for example, (a) a DNA topoisomerase I or II inhibitor; (b) a DNA damaging agent; (c) an antimetabolite or TS inhibitor; (d) a microtubule targeted agent; and (e) ionising radiation.
