  Bis-aryl Urea Derivatives as Potent and Selective LIM Kinase (Limk) Inhibitors

  摘要：

  The discovery/optimization of bis-aryl ureas as Limk inhibitors to obtain high potency and selectivity and appropriate pharmacokinetic properties through systematic SAR studies is reported. Docking studies supported the observed SAR. Optimized Limk inhibitors had high biochemical potency (IC50 < 25 nM), excellent selectivity against ROCK and JNK kinases (>400-fold), potent inhibition of cofilin phosphorylation in A7r5, PC-3, and CEM-SS T cells (IC50 < 1 mu M), and good in vitro and in vivo pharmacokinetic properties. In the profiling against a panel of 61 kinases, compound 18b at 1 mu M inhibited only Limk1 and STK16 with >= 80% inhibition. Compounds 18b and 18f were highly efficient in inhibiting cell-invasion/migration in PC-3 cells. In addition, compound 18w was demonstrated to be effective on reducing intraocular pressure (IOP) on rat eyes. Taken together, these data demonstrated that we had developed a novel class of bis-aryl urea derived potent and selective Limk inhibitors.

  Borrowing Hydrogen (BH), also called Hydrogen Autotransfer (HA), reaction with neat ethylene glycol represents a key step in the preparation of β-amino alcohols. However, due to the stability of ethylene glycol, mono-activation has rarely been achieved. Herein, a combination of Pd/C and ZnO is reported as heterogeneous catalyst for this BH/HA reaction. This system results in an extremely air and moisture

  与纯乙二醇的借入氢（BH）也称为氢自动转移（HA），是制备β-氨基醇的关键步骤。然而，由于乙二醇的稳定性，很少实现单活化。在此，据报道Pd / C和ZnO的组合作为该BH / HA反应的非均相催化剂。该系统产生了极好的空气和湿气稳定性，并且经济的催化剂能够将水中的乙二醇单官能化，而无需进一步活化二醇。在这项工作中，已经探索了不同的二醇和芳族胺，为氨基醇的开发提供了一种新方法。这项研究揭示了两种固体物质的组合如何在异相中提供有趣的催化性能。ZnO激活乙二醇，而Pd / C则负责BH / HA循环。重新芳香化之前的原位BH / HA循环，代表串联异质过程。
