  • Identification of Terfenadine as an Inhibitor of Human CD81-Receptor HCV-E2 Interaction: Synthesis and Structure Optimization
    作者:Marcel Holzer、Sigrid Ziegler、Beatrice Albrecht、Bernd Kronenberger、Artur Kaul、Ralf Bartenschlager、Lars Kattner、Christian Klein、Rolf Hartmann
    DOI:10.3390/molecules13051081

    Terfenadine (4-[4-(hydroxydiphenylmethyl)-1-piperidyl]-1-(4-tert-butylphenyl)-butan-1-ol) was identified in a biological screening to be a moderate inhibitor (27% inhibition) of the CD81-LEL–HCV-E2 interaction. To increase the observed biologicalactivity, 63 terfenadine derivates were synthesized via microwave assisted nucleophilicsubstitution. The prepared compounds were tested for their inhibitory potency by means ofa fluorescence labeled antibody assay using HUH7.5 cells. Distinct structure-activityrelationships could be derived. Optimization was successful, leading to 3g, identfied as themost potent compound (69 % inhibition). Experiments with viral particles revealed thatthere might be additional HCV infection reducing mechanisms.
    特非那定(4-[4-(羟二苯甲基)-1-哌啶基]-1-(4-叔丁基苯基)-丁烷-1-醇)在生物筛选中被识别为中等抑制剂(抑制率为27%),针对CD81-LEL与HCV-E2的相互作用。为了提高观察到的生物活性,通过微波辅助亲核取代合成了63个特非那定衍生物。这些制备的化合物通过使用HUH7.5细胞的荧光标记抗体检测法测试了它们的抑制效力。可以得出明显的结构-活性关系。优化取得了成功,导致了3g的识别,这是最强效的化合物(抑制率为69%)。对病毒颗粒的实验揭示可能存在额外的降低HCV感染的机制。
  • Iminyl Radicals by Reductive Cleavage of N–O Bond in Oxime Ether Promoted by SmI<sub>2</sub>: A Straightforward Synthesis of Five-Membered Cyclic Imines
    作者:Fei Huang、Songlin Zhang
    DOI:10.1021/acs.orglett.9b02740
    日期:2019.9.20
    A new generation method of N-centered radicals from the reductive cleavage of the N-O bond in oxime ether promoted by SmI2 is reported for the first time. The in-situ-generated N-centered radicals underwent intramolecular cyclization to afford five-membered cyclic imines in two manners: N-centered radical addition and N-centered anion nucleophilic substitution. From a synthetic point of view, an efficient
    首次报道了由SmI2促进的肟醚中NO键的还原性裂解形成的一种以N为中心的自由基的新方法。原位生成的N中心自由基经过分子内环化以两种方式提供五元环亚胺:N中心自由基加成和N中心阴离子亲核取代。从合成的观点出发,开发了一种有效的五元环亚胺的合成方法。提出了一种转化机制。
  • Visible-Light Mediated Oxidative Fragmentation of Ethers and Acetals by Means of Fe(III) Catalysis
    作者:Rickard Lindroth、Alica Ondrejková、Carl-Johan Wallentin
    DOI:10.1021/acs.orglett.2c00231
    日期:2022.3.4
    A new method employing iron(III) acetylacetonate along with visible light is described to effect oxidative ring opening of cyclic ethers and acetals with unparalleled efficiency. The method allows for a photocatalytic radical chemistry approach to functionalize relatively inert cyclic ethers into useful synthetic intermediates. The methodology sheds further light on the use of underexplored iron complexes

    作者:Charles A. Harbert、Jacob J. Plattner、Willard M. Welch、Albert Weissman、B. Kenneth Koe
    DOI:10.1021/jm00180a011
    日期:1980.6
    A series of 5-aryltetrahydro-gamma-carbolines was prepared by a novel N-arylation procedure and tested for neuroleptic activity in a rat antiamphetamine model. The systematic exploration of structural parameters leading to 8-fluoro-5-(4-fluorophenyl)-2-[4-hydroxy-4-(4-fluorophenyl)butyl]-2,3,5-tetrahydro-1H-pyrido[4,3-b]indole (CP-36,584, flutroline), a potent and long-acting neuroleptic compound, is described. These semirigid compounds provide a new, structurally distinct series with which to probe the conformational requirements for potent activity at the dopamine receptor.
