Novel pyrazolopyrimidines of formula (I):
are discussed. These pyrazolopyrimidines are capable of inhibiting the activity of cyclin-dependent kinases, most particularly cyclin-dependent kinase 1 (Cdk1), cyclin-dependent kinase 2 (Cdk2), and cyclin-dependent kinase 4 (Cdk4) and are thus useful, inter alia, in the treatment or control of cancer, in particular solid tumors. This invention also provides pharmaceutical compositions containing such compounds and to methods of treating or controlling cancer, most particularly the treatment or control of breast, lung, colon and prostate tumors.
讨论了化学式(I)的新型吡唑吡咯嘧啶。这些吡唑吡咯嘧啶能够抑制细胞周期依赖性激酶的活性,尤其是细胞周期依赖性激酶1(Cdk1)、细胞周期依赖性激酶2(Cdk2)和细胞周期依赖性激酶4(Cdk4),因此在癌症的治疗或控制中具有用途,特别是对固体肿瘤。该发明还提供了含有这些化合物的药物组合物以及治疗或控制癌症的方法,尤其是乳腺癌、肺癌、结肠癌和前列腺癌的治疗或控制。
