This invention provides pyridopyrimidines and 4-aminopyrimidines that are useful for treating cell proliferatives disorders, such as cancer and restenosis. We have now discovered a group of 7,8-dihydro-2-(amino and thio)pyrido[2,3-d]pyrimidincs and 2,4-diaminopyrimidines that are potent inhibors of cyclin-dependent kinases (cdks) and growth factor-mediated kinases. The compounds are readily synthesized and can be administered by a variety of routes, including orally, and have sufficient bioavailability. This invention provides compounds of Formula (I) and Formula (II) where W is NH, S, SO or SO2, R1 includes phenyl and substituted phenyl, R2 includes alkyl and cycloalkyl, R3 includes alkyl and hydrogen, R8 and R9 include hydrogen and alkyl, and Z is carboxy. This invention also provides pharmaceutical formulations comprising a compound of Formula (I and II) together with a pharmaceutically acceptable carrier, diluent, or excipient therefor.
