  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。

• Iridium-catalyzed C–H borylation of pyridines

  DOI：10.1039/c4ob01565g

  日期：——

  The iridium-catalysed C–H borylation is a valuable and attractive method for the preparation of aryl and heteroaryl boronates. However, application of this methodology for the preparation of pyridyl and related azinyl boronates can be challenged by low reactivity and propensity for rapid protodeborylation, particularly for a boronate ester ortho to the azinyl nitrogen. Competition experiments have revealed that the low reactivity is due to inhibition of the active catalyst through coordination of the azinyl nitrogen lone pair at the vacant site on the iridium. This effect can be overcome through the incorporation of a substituent at C-2. Moreover, when this is sufficiently electron-withdrawing protodeborylation is sufficiently slowed to permit isolation and purification of the C-6 boronate ester. Following functionalization, reduction of the directing C-2 substituent provides the product arising from formal ortho borylation of an unhindered pyridine ring.

  铱催化的C-H硼化是一种有价值且有吸引力的方法，用于制备芳基和杂芳基硼酸酯。然而，这种方法在制备吡啶基及相关氮杂基硼酸酯时可能面临反应活性低和快速质子脱硼化的挑战，尤其是当硼酸酯位于氮杂基氮原子的邻位时。竞争实验揭示，低反应活性是由于氮杂基氮原子的孤对电子在铱的空位上配位，抑制了活性催化剂。通过在C-2位引入取代基可以克服这一效应。此外，当该取代基足够吸电子时，质子脱硼化过程会被足够减缓，从而允许分离和纯化C-6硼酸酯。经过功能化后，导向C-2取代基的还原提供了源自未受阻吡啶环形式邻位硼化的产物。
