Compounds of formula (I) or salts, N-oxides, hydrates or solvates thereof are inhibitors of kinase activity, and useful for the treatment of, for example, cancer, psoriasis or restenosis: wherein ring A is an optionally substituted carbocyclic or heterocyclic radical. Alk represents an optionally substituted divalent Cl-C6 alkylene radical. n is 0 or 1. Q represents a radical of formula -(Alk1)P (X)r-(Alk2)S -Z wherein in any compatible combination Z is hydrogen or an optionally substituted carbocyclic or heterocyclic ring; Alk1 and Alk2 are optionally substituted divalent C1-C6 alkylene radicals which may contain a -0-, -S- or -NR A_ link, wherein RA is hydrogen or Cl-C6 alkyl; X represents -0-, -S-, -(C=O)-, -(C=S)-, -SO2-, -SO-, -C(=O)O-, -OC(=O)-, -C(=O)NRA-, -NR AC(=O)-, -C(=S)NRA-, -NR AC(=S)-, - SO2NRA-, -NR ASO2-, -OC(=O)NRA-, -NR AC(=O)O-, or -NRA- wherein RA is hydrogen or C1-C6 alkyl. p, r and s are independently 0 or 1. R1 represents a radical -(Alk3)a-(Y)b-(Alk4)d-B wherein a, b and d are independently 0 or 1; Alk3 and Alk4 are optionally substituted divalent C,-C3 alkylene radicals; Y represents a monocyclic divalent carbocyclic or heterocyclic radical having from 5 to 8 ring atoms, -0-, -S-, or -NRA- wherein RA is hydrogen or C1-C6 alkyl; B represents hydrogen or halo, or an optionally substituted monocyclic carbocyclic or heterocyclic ring having from 5 to 8 ring atoms, or in the case where Y is -NRA- and b is 1, then RA and the radical -(Alk4)d-B taken together with the nitrogen to which they are attached may form an optionally substituted heterocyclic ring. R represents hydrogen, halo, Cl-C6 alkyl, Cl-C6 alkoxy, C1-C6 alkylthio, phenyl, benzyl, cycloalkyl with 3 to 6 ring atoms, or a monocyclic heterocyclic group having 5 or 6 ring atoms.
