passing Phase II clinical trials for cancer and glomerulonephritis. In this article, we describe a novel modification of the purine scaffold influencing CDK2 inhibitory activities as well as anticancer properties in cell lines of different histopathological origin. The introduced N at position 8 of the purine ring generally lowered CDK2 inhibitory activity of new 8-azapurines (1,2,3-triazolo[4,5-d]pyrimidines)
嘌呤抑制剂细胞周期蛋白依赖性激酶(CDK)似乎是潜在的抗癌药物候选物,首批代表药物roscovitine已通过癌症和肾小球肾炎的II期临床试验。在本文中,我们描述了嘌呤支架的新颖修饰,可影响不同组织病理学起源的细胞系中的CDK2抑制活性以及抗癌特性。与模型三取代嘌呤相比,在嘌呤环第8位引入的N通常会降低新的8-氮杂嘌呤(1,2,3-三唑并[4,5-d]嘧啶)的CDK2抑制活性,而该模型的抗增殖潜力一些衍生物仍然很高,反映出它们激活p53肿瘤抑制因子的能力。
