4-((3,5-二氯-2-羟基苄基)氨基)-2-羟基苯甲酸(ZL006,1)是nNOS / PSD-95相互作用的小分子抑制剂,目前处于脑缺血的临床前评估阶段。但是,新陈代谢的快速性和跨血脑屏障(BBB)的低渗透性限制了它的进一步使用。在该手稿中,质谱分析表明ZL006主要与葡萄糖醛酸在小鼠血浆中结合,从而加速了其代谢和清除。因此,根据ZL006可能的代谢位点设计了六个ZL006类似物,并以酚羟基,仲胺和羧基上的烷基化为特征。这些化合物的合成产率中等至良好,并通过1 H NMR和MS进行了全面表征。

and pentachloropseudilin represent a new class of isoform-specific allosteric inhibitors of myosinATPase. Herein, we describe an application of the silver(I)-catalyzed cycloisomerization of N-(homopropargyl)toluenesulfonamides to the total syntheses of these natural products and several non-natural analogues. Moreover, we examine the inhibitiory effect of pentahalogenated pseudilins on myosin ATPase
五卤化 2-芳基吡咯型生物碱 pentabrompseudilin 和 pentachloropseudin 代表了一类新的肌球蛋白 ATP 酶的异构体特异性变构抑制剂。在此,我们描述了银 (I) 催化的 N-(高炔丙基)甲苯磺酰胺环异构化在这些天然产物和几种非天然类似物的全合成中的应用。此外,我们检查了五卤化假素对肌球蛋白 ATP 酶活性的抑制作用。

An efficient C–O amination of arylmethylethers has been achieved. This transformation proceeds via imine-directed Ti(IV)-mediated cross-coupling reactions between arylmethylethers and Ti(NR2)4 at room temperature, straightforwardly leading to a series of arylamines. This protocol features a wide substrate scope, exclusive regioselectivity, and mild reaction conditions.

Stopping myo: The total syntheses of the title compounds have been achieved using a highly efficient silver(I)‐catalyzedcyclization of N‐tosyl‐homopropargylamines. The pseudilin derivatives represent a novel class of myosin inhibitors. A new allosteric binding pocket of the Dictyostelium myosin‐2 motor domain has been identified for pentabromopseudilin (1) by using an X‐ray crystal structure determination
