Design and synthesis of highly selective, orally active Polo-like kinase-2 (Plk-2) inhibitors
摘要:
Polo-like kinase-2 (Plk-2) is a potential therapeutic target for Parkinson's disease and this Letter describes the SAR of a series of dihydropteridinone based Plk-2 inhibitors. By optimizing both the N-8 substituent and the biaryl region of the inhibitors we obtained single digit nanomolar compounds such as 37 with excellent selectivity for Plk-2 over Plk-1. When dosed orally in rats, compound 37 demonstrated a 41-45% reduction of pS129-alpha-synuclein levels in the cerebral cortex. (C) 2013 Elsevier Ltd. All rights reserved.

inhibition of polo-likekinase1 (PLK1) and BRD4 bromodomain by a single molecule could lead to the development of an effective therapeutic strategy for a variety of diseases in which PLK1 and BRD4 are implicated. Compound 23 has been found to be a potent dual kinase-bromodomain inhibitor (BRD4-BD1 IC50 = 28 nM, PLK1 IC50 = 40 nM). Compound 6 was found to be the most selective PLK1inhibitor over BRD4

The present account describes the discovery and development of a new benzo[c]pyrrolo[2,3-h][1,6]naphthyridin-5-one (BPN) JAK inhibitory chemotype that has produced selective JAK inhibitors. Sequential palladium chemistry was optimized for the rapid access to a focused library of derivatives to explore the structure–activity relationships of the new scaffold. Several compounds from the series displayed
该文献描述了已经产生选择性JAK抑制剂的新型苯并[ c ]吡咯并[2,3- h ] [1,6]萘啶-5-酮(BPN)JAK抑制化学型的发现和开发。优化了顺序钯化学,可快速访问聚焦的衍生物库,以探索新支架的结构与活性之间的关系。该系列中的几种化合物对JAK家族的四个成员具有不同选择性的低纳摩尔浓度范围。具有氮杂环丁烷酰胺侧链的化合物20a显示出对JAK1激酶相对于JAK2,JAK3和TYK2的最佳选择性,且纳摩尔浓度低(IC 50 = 3.4 nM)。另一方面,BPN 17b和18对JAK家族具有良好的总体活性,并具有优异的kinome选择性特征。许多新的BPN抑制JAK3介导的STAT-5磷酸化,炎性细胞因子的产生以及原代T细胞的增殖。此外,在类风湿性关节炎动物模型中,BPN 17b的体内结果与托法替尼非常相似。
