ABSTRACT:
Disclosed are compounds of Formulae (Ia), (Ib), (Ic), (Id) wherein: W is NH, S, SO, or SO2; R2is (un)substituted aryl, (un)substituted heteroaryl, or (un)substituted carbocycle or heterocycle; Q is hydrogen or lower alkyl; R4and R6are the same or different and represent hydrogen, halogen, lower alkyl, lower alkoxy, (un)substituted aryl, (un)substituted heteroaryl, (un)substituted arylalkyl or (un)substituted heteroarylalkyl; and R8is hydrogen, lower alkyl or an (un)substituted carbocyclic group containing from 3–7 members, up to two of which members are optionally hetero atoms selected from oxygen and nitrogen; or R8is (un)substituted aryl, (un)substituted heteroaryl, (un)substituted arylalkyl or (un)substituted heteroarylalkyl. These compounds are useful for treating cell proliferative disorders, such as cancer and restenosis. These compounds are potent inhibitors of cyclin-dependent kinases (cdks) and growth factor-mediated kinases. The present invention also provides a method of treating cell proliferative disorders. Also provided by the present invention is a pharmaceutically acceptable composition containing a compound of Formula (I).
