  We herein report the conventional and microscale parallel synthesis of selective inhibitors of human blood coagulation factor XIIa and thrombin exhibiting a 1,2,4-triazol-5-amine scaffold. Structural variations of this scaffold allowed identifying derivative 21i, a potent 29 nM inhibitor of FXIIa, with improved selectivity over other tested serine proteases and also finding compound 21m with 27 nM

  我们在此报告了常规和微观并行合成的人类凝血因子XIIa和凝血酶的选择性抑制剂，这些抑制剂表现出1,2,4-三唑-5-胺骨架。该支架的结构变异允许鉴定衍生物21i（一种有效的FXIIa抑制剂29nM），具有比其他经过测试的丝氨酸蛋白酶更高的选择性，还可以发现化合物21m对凝血酶具有27 nM的抑制活性。首次证明酰化的1,2,4-三唑-5-胺具有抗凝特性，并具有影响凝血酶和癌细胞诱导的血小板凝集的能力。进行的质谱分析和分子建模使我们能够发现合成的抑制剂与FXIIa活性位点之间以前未知的相互作用，从而揭示了FXIIa抑制的机理细节。合成的化合物代表了开发新的抗血栓药物或化学工具以研究FXIIa和凝血酶在生理和病理过程中的作用的有希望的起点。

  A superior substrate sequence for BACE1 containing transition-state mimics at the scissile site was evaluated as a protease inhibitor. Hydroxymethylcarbonyl (HMC) and hydroxyethylamine (HEA) isosteres were selected as the transition state mimics, and incorporated into the scissile site of the superior sequence covering the P4 to P1’ sites (Glu-Ile-Thi-Thi*Nva; *denotes the cleavage site). Isosteres

  易位处含有过渡态模拟物的BACE1的优良底物序列被评估为蛋白酶抑制剂。选择羟甲基羰基（HMC）和羟乙胺（HEA）等位基因作为过渡态模拟物，并将其并入覆盖P 4至P 1 '位的上位序列的易剪位点（Glu-Ile-Thi-Thi * Nva；*表示卵裂位点）。分别合成具有不同的羟基绝对构型的等排体，并评价构型的效果。每个等排异构体的羟基构型均显示出对抑制活性的显着影响。反对-易位部位取代基的构型在HMC型抑制剂中具有有效的抑制活性，而HEA型抑制剂的抗构型则没有抑制活性。基于重组BACE1与每种抑制剂的复合物的X射线晶体学分析进行结构评估，可深入了解蛋白质-配体之间的相互作用，尤其是在主要位点。

  known synthetic methods often suffer from the disadvantage of being specific only to certain substrates. Herein, we describe a facile decarboxylative thioesterification of alkyl acid derived redox-active esters by merging photoredox catalysis and copper catalysis. This reaction is applicable to a wide range of carboxylic acids, as well as natural products and drugs, allowing for the synthesis of various

  硫酯和相关的硫醇对生物系统至关重要，也广泛用于合成重要的药物分子和高分子材料。然而，已知的合成方法经常具有仅对某些底物特异的缺点。在本文中，我们描述了通过合并光氧化还原催化和铜催化而对烷基酸衍生的氧化还原活性酯进行的容易的脱羧硫酯化。该反应适用于各种羧酸，以及天然产物和药物，从而可以合成具有不同结构的各种硫酯，包括叔卤化物，这些卤化物不能通过传统的亲核取代从叔卤化物中获得。此外，通过将硫酯直接转化为磺酰氟证明了产品的利用。
