  Initial Process Development and Scale-Up of the Synthesis of a Triple Reuptake Inhibitor ALB 109780

  摘要：

  Early process development toward a triple reuptake inhibitor is described. Three different routes were evaluated; one of them was optimized and scaled up to generate 470 g of API as this route minimized the formation of undesired side products. The selected route featured Eaton's reagent-mediated cyclization of a phenyl acetamide, copper-mediated Buchwald Hartwig coupling to install a morpholine moiety, and palladium-catalyzed alpha-arylation of a dihydroisoquinolinone to construct the core structure.

  Renewed interest in covalent inhibitors of enzymes implicated in disease states has afforded several agents targeted at protein kinases of relevance to cancers. We now report the design, synthesis and biological evaluation of 6-ethynylpurines that act as covalent inhibitors of Nek2 by capturing a cysteine residue (Cys22) close to the catalytic domain of this protein kinase. Examination of the crystal

  人们对与疾病状态有关的酶的共价抑制剂重新产生了兴趣，从而提供了几种针对与癌症相关的蛋白激酶的药物。我们现在报告了 6-乙炔基嘌呤的设计、合成和生物学评价，6-乙炔基嘌呤通过捕获靠近该蛋白激酶催化结构域的半胱氨酸残基 (Cys22) 来充当 Nek2 的共价抑制剂。对与 Nek2 复合的非共价抑制剂 3-((6-环己基甲氧基-7 H-嘌呤-2-基)氨基)苯甲酰胺的晶体结构的检查表明，用乙炔基取代烷氧基放置了炔烃的末端接近Cys22并且处于与迈克尔加成的立体电子学要求兼容的位置。制备了一系列 6-乙炔基嘌呤并建立了抑制 Nek2 的结构活性关系 (SAR)。 6-乙炔基-N-苯基-7 H-嘌呤-2-胺 [IC 50 0.15 μM (Nek2)] 和 4-((6-乙炔基-7 H-嘌呤-2-基)氨基)苯磺酰胺 (IC 50 0.14)选择 Nek2 的抑制模式来确定 Nek2 的抑制模式，该抑制模式具有时间依赖性，不能通过添加

  explore diverse sets of reaction conditions, and problems with product purification. In contrast, product isolation from TFA‐TFE reactions is straightforward: evaporation of the reaction mixture, basification and chromatography affords analytically pure material. A total of 45 examples are described with seven discrete heterocyclic scaffolds and 2‐, 3‐ and 4‐substituted anilines giving product yields

  小分子药物的发现需要可靠的合成方法，以将氨基化合物连接到杂环支架上。三氟乙酸-2,2,2-三氟乙醇（TFA-TFE）是实现S N的有效组合苯胺与杂环（例如嘌呤和嘧啶）之间的Ar反应被离去基团（氟，氯，溴或烷基磺酰基）取代。该方法提供了多种化合物，这些化合物含有与激酶有效抑制有关的“激酶特权片段”。TFE由于其低亲核性，易于去除和溶解极性底物的能力而成为有利的溶剂。此外，TFE可以通过使离去基团溶剂化来协助Meisenheimer-Jackson中间体的分解。TFA是必要且有效的酸性催化剂，它可以通过N质子化作用活化杂环，而不会通过转化为苯胺类物质而使苯胺失活。TFA-TFE方法与各种官能团兼容，并补充了有机金属替代品，由于试剂的昂贵，经常需要探索各种反应条件以及产物纯化的问题，这通常是不利的。相比之下，从TFA-TFE反应中分离产物非常简单：反应混合物的蒸发，碱化和色谱分离得到分析纯的物质
