The invention provides compounds of the formula (I) or a salt, tautomer, solvate or N-oxides thereof; wherein: R 1 is selected from (a) 2,6-dichlorophenyl; (b) 2,6-difluorophenyl; (c) a 2,3,6-trisubstituted phenyl group wherein the substituents are fluorine, chlorine, methyl or methoxy; and (d) a group R 0 wherein R 0 is a 3-12 membered carbocyclic or heterocyclic group; or optionally substituted C 1-8 hydrocarbyl; R 2a and R 2b are each hydrogen or methyl; and R 3 is as defined in the claims. The compounds have activity as inhibitors of Cyclin Dependent Kinases (CDK) and Glycogen Synthase Kinases (GSK) kinases and are useful in the treatment or prophylaxis of disease states or conditions mediated by the kinases. |
