  Inhibition of Cytosolic Phospholipase A₂α: Hit to Lead Optimization

  摘要：

  Compound I was previously reported to be a potent inhibitor of cPLA,(x in both artificial monomeric substrate and cell-based assays. However, I was inactive in whole blood assays previously used to characterize cyclooxygenase and lipoxygenase inhibitors. The IC(50) of 1 increased dramatically with cell number or lipid/detergent concentration. In an attempt to insert an electrophilic ketone between the indole and benzoic acid moieties, we discovered that increasing the distance between the two moieties gave a compound with activity in the GLU (7-hydroxycoumarinyl-gamma-linolenate) micelle assay, which contains lipid and detergent. Extensive structure-activity relationship work around this lead identified a potent pharmacophore for cPLA a inhibition. The IC(50)s between the GLU micelle and rat whole blood assays correlated highly. No correlation was found for other parameters, including lipophilicity or acidity of the required acid functionality. Compounds 25, 39, and 94 emerged as potent, selective inhibitors of cPLA(2)alpha and represent well-validated starting points for further optimization.

  Presented here is a class of novel axially chiral aryl‐p ‐quinones as platform molecules for the preparation of non‐C 2 symmetric biaryldiols. Two sets of aryl‐p ‐quinone frameworks were synthesized with remarkable enantiocontrol by means of chiral phosphoric acid catalyzed enantioselective arylation of p ‐quinones by central‐to‐axial chirality conversion. These aryl‐p ‐quinones were then used to access

  芳烃的官能化代表构建重要的芳基化合物的核心骨架的最有效方法。与发达电芳族取代和过渡金属催化的C-H活化，相比亲核芳香取代遗体由于缺乏对于σ的快速转换一个方便的途径的挑战ħ加合物到其他稳定和通用中间体原位。在计算设计的指导下，我们能够通过手性磷酸催化在萘上引入亚硝基来实现不对称的亲核芳族取代。该策略使得能够以优异的立体控制有效地构建阻转异构的吲哚-萘和吲哚-苯胺。密度泛函理论（DFT）计算为对映选择性的起源和反应机理提供了进一步的见解。在合成NOBINs（2-氨基-2'-羟基-1,1'-联萘基）方面的成功应用扩展了该策略的实用性。
