  4-Aminoquinolines:  Novel Nociceptin Antagonists with Analgesic Activity

  摘要：

  Small-molecule nociceptin antagonists were synthesized to examine their therapeutic potential. After a 4-aminoquinoline derivative was found to bind with the human ORL1 receptor, a series of 4-aminoquinolines and related compounds were synthesized and their binding was evaluated. Elucidation of structure-activity relationships eventually led to the optimum compounds. One of the se compounds, N-(4-amino-2-methylquinolin-6-yl) -2-(4-ethylphenoxymethyl)benzamide hydrochloride (11) not only antagonized nociceptin-induced allodynia in mice but also showed analgesic effect in a hot plate test using mice and in a formalin test using rats. Its analgesic effect was not antagonized by the opioid antagonist naloxone. These results indicate that this nociceptin antagonist has the potential to become a novel type of analgesic that differs from mu -opioid agonists.

  镍卤化物与乙烯基溴的镍催化还原偶联制备乙烯基芳烃

  摘要：

  这项工作强调了在温和且易于操作的镍催化反应条件下，通过芳基卤化物与乙烯基溴的还原偶联来合成取代的乙烯基芳烃。广泛使用的芳基卤化物，包括杂芳族化合物和乙烯基溴化物，以中等至优异的收率生产了具有高官能团耐受性的产品。镍催化系统在两个C（sp 2）-卤化物偶合体之间显示出良好的化学选择性，从而证明了不同于其他逐步方案的机理途径。

  present our approach based on de novo structure-based drug design. Using known structural information from complexes engaging opposing members of the BCL-2 family of proteins, we designed peptidomimetic compounds using a benzoylurea scaffold to reproduce key interactions between these proteins. A library stemming from the initial de novo designed scaffold led to the discovery of ligands with low micromolar

  存活的BCL-2蛋白对于药物化学家而言是有吸引力的但具有挑战性的靶标。它们参与了许多（如果不是全部）肿瘤的发生和发展，使其成为开发新的抗癌疗法的主要靶标。我们介绍了基于从头结构的药物设计方法。利用来自参与BCL-2蛋白质家族相对成员的复合物的已知结构信息，我们使用苯甲酰脲支架设计了拟肽化合物，以再现这些蛋白质之间的关键相互作用。从初始从头词干的文库设计的支架导致与低微摩尔效力（配位体的发现ķ d = 4μM）和选择性BCL-X大号。这些化合物以不同于先前已知的BCL-2抑制剂的结合方式在规范的BH3结合槽中结合。我们的研究结果为针对具有挑战性的蛋白质-蛋白质相互作用类的新型拮抗剂的设计提供了见识。

  ABSTRACT Efficient Mizoroki–Heck couplings were obtained using a very easily synthesizable palladium(II) complex of hemilabile N–O ligand (picolinate), with high turnover frequencies up to >10,000 h−1, in just 15 min, with high selectivity of >99% to the desired products. Wide applicability of the simple-looking palladium complex catalyst was established with differently functionalized substrates.

  alkynes with N-pivaloyloxy aryl amides enabled the efficient regiospecific synthesis of difluorinated 2-alkenyl aniline derivatives (see scheme). The fluorine substituents in the alkyne substrates diverted the course of the reaction from the conventional annulation pathway to promote the hydroarylation process involving Lossen rearrangement.
