and implies a protective role for the kinases against cell death. Downregulation of these enzymes by chemical methods promotes apoptosis in cells. The aim of the present study was to explore the anticancer activity of inhibitors of protein kinases CK2 and PIM-1 on neoplastic cell lines in vitro. We studied a series of deoxynucleosides with various tetrahalobenzimidazoles as aglycone moiety. Cytotoxicity
在许多癌症病例中,CK2和PIM-1丝氨酸/苏氨酸激酶的含量异常高。细胞中CK2和PIM-1的升高需要抑制细胞凋亡,并暗示激酶对细胞死亡具有保护作用。通过化学方法将这些酶下调可促进细胞凋亡。本研究的目的是探讨蛋白激酶CK2和PIM-1抑制剂在体外对肿瘤细胞系的抗癌活性。我们研究了一系列以各种四卤代苯并咪唑类作为糖苷配基的脱氧核苷。通过流式细胞术和其他方法确定了细胞毒性,被测抑制剂诱导的凋亡,线粒体膜电位,胱天蛋白酶的活性,细胞周期进程的变化以及作用机制。结果表明,所研究的化合物,例如1-(β-D-2'-deoxyribofuranosyl)-4,5,6,7-tetrabromo-1H-benzimidazole,称为K164(也称为TDB),具有多种细胞毒性和促凋亡功效在细胞系中。我们的结果表明,所测试的化合物是用于靶向治疗的潜在抗癌药,尤其是在治疗髓样白血病和雄激素反应性前列腺癌中。
