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.
本文讨论了式(I)的新型
吡唑并
嘧啶类化合物,这些化合物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),因此在治疗或控制癌症,尤其是实体瘤方面具有用途。本发明还提供了含有此类化合物的药物组合物以及治疗或控制癌症的方法,尤其是治疗或控制乳腺癌、肺癌、结肠癌和前列腺癌的方法。
