Disclosed are compounds of the formula
wherein:
W is NH, S, SO, or SO
2
;
R
2
is (un)substituted aryl, (un)substituted heteroaryl, or (un)substituted carbocycle or heterocycle; Q is hydrogen or lower alkyl;
R
4
and R
6
are 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
R
8
is 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
R
8
is (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.
