Through a structure-guided rational drug design approach, we have discovered a highly selective inhibitor compound 40 (JSH-150), which exhibited an IC50 of 1 nM against CDK9 kinase in the biochemical assay and achieved around 300–10000-fold selectivity over other CDK kinase family members. In addition, it also displayed high selectivity over other 468 kinases/mutants (KINOMEscan S score(1) = 0.01)
通过结构指导的合理药物设计方法,我们发现了一种高度选择性的抑制剂化合物40(JSH-150),在生化分析中对CDK9激酶的IC 50为1 nM,相对于CDK9激酶具有约300-10000倍的选择性。其他CDK激酶家族成员。此外,它还显示出对其他468种激酶/突变体的高选择性(KINOMEscan S得分(1)= 0.01)。化合物40显示出对黑素瘤,神经母细胞瘤,肝癌,结肠癌,肺癌以及白血病细胞系的有效抗增殖作用。它可以剂量依赖性地抑制RNA Pol II的磷酸化,抑制MCL-1和c-Myc的表达,阻滞细胞周期并诱导白血病细胞凋亡。在MV4-11细胞接种的异种移植小鼠模型中,10 mg / kg剂量的40剂量几乎可以完全抑制肿瘤的进展。高选择性和良好的体内PK / PD特性表明40是研究CDK9介导的生理学和病理学的良好药理工具,也是白血病和其他癌症的潜在候选药物。
