Cyclin-dependent kinase 8 (CDK8) plays a vital role in regulating cell transcription either through its association with the mediator complex or by the phosphorylation of transcription factors. CDK8-mediated activation of oncogenes has proved to be important in a variety of cancer types including hematological malignancies. We have designed and synthesized a series of new synthetic steroids. The compounds were evaluated as CDK8 inhibitors in vitro. The three most potent compounds exhibit Kd-values towards CDK8 in the low nanomolar range (3.5-18 nM). Furthermore, the compounds displayed selectivity for CDK8 in a panel of 465 different kinases. The cell studies indicated a selectivity to kill AML-cancer cell lines compared to normal cell lines.

作为潜在抗白血病药的新型CDK8抑制剂-设计,合成和生物学评估。

细胞周期蛋白依赖性激酶8(CDK8)通过与介体复合物结合或通过转录因子的磷酸化在调节细胞转录中起着至关重要的作用。事实证明,CDK8介导的癌基因激活在包括血液系统恶性肿瘤在内的多种癌症中都很重要。我们设计并合成了一系列新的合成类固醇。将该化合物在体外评价为CDK8抑制剂。三种最有效的化合物在低纳摩尔范围(3.5-18 nM)中对CDK8表现出Kd值。此外,这些化合物在一组465种不同的激酶中显示出对CDK8的选择性。细胞研究表明,与正常细胞系相比,杀伤AML癌细胞的选择性更高。
