, (2008/06/13)
Compounds of formula (I) wherein: R1 is halo, nitro, cyano, hydroxy, amino, carboxy, carbamoyl, mercapto, C1-6alkyl, C2-6alkenyl or C2-6alkynyl; p is 0-4; wherein the values of R1 may be the same or different; R2 is sulphamoyl or a group B—E—; wherein B is optionally substituted as defined within and is selected from C1-6alkyl, C2-6alkenyl, C2-6alkynyl, C3-8cycloalkyl, C1-6alkyl, phenyl, a heterocyclic group, phenylC1-6alkyl or (heterocyclic group)C1-6alkyl; E is C(O)—, N(Ra)C(O)—, —C(O)N(Ra)—, —S(O)r—, —SO2N(Ra)— or —N(Ra)SO2—; wherein Ra is hydrogen or C1-6alkyl optionally substituted as defined within and r is 1-2; q is 0-2; wherein the values of R2 may be the same or different; and wherein p+q=1-5; or a pharmaceutically acceptable salt or an in vivo hydrolysable ester thereof are described. Processes for their manufacture and their use as inhibitors of cell cycle kinases, particularly CDK2, CDK4 and/or CDK6 are also described.
