This invention provides pyridopyrimidines and 4-aminopyrimidines that are useful for treating cell proliferative disorders, such as cancer and restenosis. We have now discovered a group of 7,8-dihydro-2-(amino and thio)pyrido[2,3-d]pyrimidines and 2,4-diaminopyrimidines that are potent inhibitors 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 or II together with a pharmaceutically acceptable carrier, diluent, or excipient therefor.
这项发明提供了用于治疗细胞增殖性疾病,如癌症和再狭窄的吡啶吡嘧啶和4-氨基吡嘧啶。我们现在发现了一组7,8-二氢-2-(氨基和硫)吡啶吡嘧啶和2,4-二氨基吡嘧啶,它们是有效的细胞周期素依赖性激酶(cdk)和生长因子介导的激酶的抑制剂。这些化合物可以轻松合成,并且可以通过多种途径,包括口服,进行给药,并具有足够的生物利用度。这项发明提供了化合物的化学式I和化学式II,其中W为NH、S、SO或SO2,R1包括苯基和取代苯基,R2包括烷基和环烷基,R3包括烷基和氢,R8和R9包括氢和烷基,Z为羧基。这项发明还提供了包含化学式I或II的化合物的药物制剂,以及与其一起使用的药学上可接受的载体、稀释剂或赋形剂。
