    Regulatory molecules for the 5-HT3 receptor ion channel gating system
    摘要:
    Substituted benzoxazole derivatives which possess a nitrogen containing heterocycle at C2 are selective partial agonists of the 5-HT3 receptor. Alteration of substituents on the benzoxazole nucleus affords both agonist-like and antagonist-like compounds, and uniquely modifies the function of the 5-HT3 receptor ion channel gating system. SAR and corroborative computational docking study for these partial agonists successfully explained structure and function of the 5-HT3 receptor. (c) 2007 Elsevier Ltd. All rights reserved.

  • Catalyst- and Reagent-Free Electrochemical Azole C−H Amination
    作者:Youai Qiu、Julia Struwe、Tjark H. Meyer、João C. A. Oliveira、Lutz Ackermann

    日期:2018.9.3
    Catalyst‐ and chemical oxidant‐free electrochemical azole C−H aminations were accomplished via crossdehydrogenative C−H/N−H functionalization. The catalyst‐free electrochemical C−H amination proved feasible on azoles with high levels of efficacy and selectivity, avoiding the use of stoichiometric oxidants under ambient conditions. Likewise, the C(sp3)−H nitrogenation proved viable under otherwise
    不含催化剂和化学氧化剂的电化学唑CH胺的胺化反应是通过交叉脱氢CH / NH官能化完成的。事实证明,无催化剂的电化学CH氨基化反应对具有高水平的效率和选择性的唑类是可行的,避免了在环境条件下使用化学计量的氧化剂。同样,C(sp 3)-H氮化在其他相同条件下也被证明是可行的。脱氢CHH胺的作用范围很广,包括环状和非环状脂肪胺以及苯胺,并且使用可持续的电力作为唯一的氧化剂。

    Oxidative amination of azoles through catalytic CH bond activation is a very important reaction due to the presence of 2‐aminoazoles in several biologically active compounds. However, most of the reported methods are performed under homogeneous reaction conditions using excess reagents and additives. Herein, we report the heterogeneous, porous γ‐MnO2‐catalyzed direct amination of benzoxazole with

    A facile and environmentally friendly method was developed through merging the ring opening of benzoxazoles with secondary amines and an iron-catalyzed oxidative cyclization towards the synthesis of 2-aminobenzoxazoles. In the oxidative cyclization step, with catalytic amounts of FeCl and aqueous H2O2 as a green oxidant, highly desirable 2-aminobenzoxazoles were isolated in excellent yields of up to 97%. A plausible radical process is proposed for the oxidative cyclization on the basis of mechanistic studies.

  • A New 5-HT3 Receptor Ligand. II. Structure-Activity Analysis of 5-HT3 Receptor Agonist Action in the Gut.
    作者:Megumi YAMADA、Yasuo SATO、Kazuko KOBAYASHI、Fukio KONNO、Tomoko SONEDA、Takashi WATANABE

    Several modified 2-piperazinyl benzoxazole derivatives, which exhibit an agonistic effect on gastrointestinal motility, were synthesized and their effects on the contraction of guinea-pig ileum were examined. The quaternary piperazinyl benzoxazole structure has a restricted conformation and stereostructure compared to those of the other 5-HT3 receptor agonists, serotonin and meta-chlorophenylbiguanide. The mutual positions of the aromatic ring, nitrogen atom and terminal amine are considered to form the pharmacophore of the 5-HT3 receptor agonist in the gut. In the serotonin-evoked reflex bradycardia [Bezold-Jarisch (B-J) reflex] inhibition test using rats the B-J reflex-inducing ratio was different for each synthesized compound. These results suggest that, in these 5-HT3 receptor agonists, the substituents of the benzoxazole ring influence the B-J reflex-inducing activity in rats.
    合成了几种对胃肠道蠕动具有兴奋作用的2-哌嗪基苯并噁唑衍生物,并研究了它们对豚鼠回肠收缩的影响。与5-HT3受体激动剂5-羟色胺和邻氯苯基双胍相比,季铵哌嗪基苯并噁唑结构具有受限的构象和立体结构。苯环、氮原子和末端胺的相对位置被认为是形成肠道5-HT3受体激动剂的药效团。在用大鼠进行的阻断血清素诱发反射性心动过缓[Bezold-Jarisch(B-J)反射]的试验中,每个合成化合物的诱发B-J反射的比例是不同的。这些结果表明,在这些5-HT3受体激动剂中,苯并噁唑环的取代基会影响大鼠的诱发B-J反射活性。
