  Hybrid approach for the design of highly affine and selective dopamine D3 receptor ligands using privileged scaffolds of biogenic amine GPCR ligands

  摘要：

  A series of compounds containing privileged scaffolds of the known histamine H-1 receptor antagonists cetirizine, mianserin, ketotifen, loratadine, and bamipine were synthesized for further optimization as ligands for the related biogenic amine binding dopamine D-3 receptor. A pharmacological screening was carried out at dopamine D-2 and D-3 receptors. In the preliminary testing various ligands have shown moderate to high affinities for dopamine D-3 receptors, for example, N-(4-{4-[benzyl(phenyl)amino]piperidin-1-yl} butylnaphthalen-2-carboxamide (19a) (hD(3) K-i = 0.3 nM; hD(2) K-i = 703 nM), leading to a selectivity ratio of 2343.

  benzhydryl amines from the reaction of readily available sulfone derivatives with amines is described. The Cu‐catalyzed desulfonylative amination not only provides structurally diverse benzhydryl amines in good yields, but is also applicable to iterative and intramolecular aminations. Control experiments suggested that the formation of a Cu‐carbene intermediate generated from the sulfone substrate,

  描述了一种由易得的砜衍生物与胺反应合成二苯甲基胺的新方法。铜催化的脱磺酰基胺化反应不仅以高收率提供结构多样的二苯甲基胺，而且还适用于迭代和分子内胺化反应。对照实验表明，从砜底物生成的铜卡宾中间体的形成，代表了去磺酰基化转化的新途径。

  4-diazacycles by diol–diamine coupling, uniquely made possible with a (pyridyl)phosphine-ligated ruthenium(II) catalyst (1). The reactions can exploit either two sequential N-alkylations or an intermediate tautomerization pathway to yield piperazines and diazepanes; diazepanes are generally inaccessible by catalytic routes. Our conditions tolerate different amines and alcohols that are relevant to key

  我们报告了通过二醇-二胺偶联合成 1,4-二氮杂环，这种偶联是通过（吡啶基）膦连接的钌 (II) 催化剂 ( 1 ) 独特实现的。这些反应可以利用两个连续的N-烷基化或中间互变异构化途径来产生哌嗪和二氮杂环庚烷；二氮杂环己烷通常无法通过催化途径获得。我们的条件容忍与关键药物平台相关的不同胺和醇。我们展示了药物 cyclizine 和 homochlorcyclizine 的合成，产率分别为 91% 和 67%。
