  • Publication number: 20080194562
    Abstract: The invention provides compounds of the formula (I) or a salt, tautomer, solvate or N-oxides thereof; wherein: R1 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 R0 wherein R0 is a 3-12 membered carbocyclic or heterocyclic group; or optionally substituted C1-8 hydrocarbyl; R2a and R2b are each hydrogen or methyl; and R3 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.
