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.
本发明提供的吡啶嘧啶和 4-氨基嘧啶可用于治疗细胞增殖性疾病,如癌症和再狭窄。我们现已发现一组 7,8-二氢-2-(氨基和硫代)吡啶并[2,3-d]嘧啶和 2,4-二氨基嘧啶,它们是细胞周期蛋白依赖性激酶(cdks)和生长因子介导的激酶的强效抑制剂。这些化合物易于合成,可通过包括口服在内的多种途径给药,并具有足够的生物利用度。本发明提供了式 (I) 和式 (II) 的化合物,其中 W 是 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 是羧基。本发明还提供了由式(I 和 II)化合物及其药学上可接受的载体、稀释剂或赋形剂组成的药物制剂。
