The invention provides a compound of the formula (I): or a salt, N-oxide, tautomer or solvate thereof, wherein X is CR5 or N; each of Q1 and Q2 is a carbon atom; Q3 is selected from S and CH; Q4 is selected from CR2 and S; provided that one of Q3 and Q4 is S and the other of Q3 and Q4 is not S; wherein when Q3 is S, there is a double bond between Q1 and Q4 and a double bond between Q2 and the adjacent ring nitrogen atom N; and when Q4 is S, there is a double bond between Q1 and Q2, and a double bond between Q3 and the adjacent ring nitrogen atom N; A is a bond or -(CH2)m-(B)n-; B is C-O, NR8(C-O) or O(C-O) wherein R1 is hydrogen or C1_4 hydrocarbyl optionally substituted by hydroxy or C1-4 alkoxy; m is 0, 1 or 2; n is 0 or 1; Ro is hydrogen or, together with NRg when present, forms a group -(CH2)p- wherein p is 2 to 4; R1 is hydrogen, a carbocyclic or heterocyclic group having from 3 to 12 ring members, or an optionally substituted C1-8 hydrocarbyl group; R2 is hydrogen, halogen, methoxy, or a C1-4 hydrocarbyl group optionally substituted by halogen, hydroxyl or methoxy; R3 and R4 together with the carbon atoms to which they are attached form an optionally substituted fused carbocyclic or heterocyclic ring having from 5 to 7 ring members of which up to 3 can be heteroatoms selected from N, O and S; and R5 is hydrogen, a group R2 or a group R10 wherein R10 is as defined in the claims. The compounds have activity as inhibitors of cyclin dependent kinases, glycogen synthase kinases and Aurora kinases.
