  • Antiplasmodial Activity of Mono- and Dimeric Carbazoles
    作者:Gerhard Bringmann、Alfons Ledermann、Jörg Holenz、Muh-Tsuen Kao、Ulrich Busse、Howard Wu、Guido François
    DOI:10.1055/s-2006-957366
    日期:1998.2
    A series of mono-and dimeric natural and structurally modified carbazoles has been tested for activity against Plasmodium falciparum. One of the monomers, the synthetic compound 1,4-diacetoxy-3-methylcarbazole (17), displays the highest activity, with an IC50 value of 1.79 µg/ml. It is distinctly more active than the as yet best natural compound, 1-hydroxy-3-methylcarbazole (4) (4).
    我们测试了一系列单体和二聚体天然咔唑和结构修饰咔唑对恶性疟原虫的活性。其中一种单体,即合成化合物 1,4-二乙酰氧基-3-甲基咔唑(17)显示出最高的活性,IC50 值为 1.79 µg/ml。它的活性明显高于目前最好的天然化合物 1-羟基-3-甲基咔唑(4)(4)。
  • The first synthesis of optically pure biscarbazoles and determination of their absolute configurations
    作者:Guoqiang Lin、Aimin Zhang
    DOI:10.1016/s0040-4039(98)02346-6
    日期:1999.1
    Optically pure dimeric O-demethylmurrayafoline A (1) and its 6,6′-dimethoxyl analog 2 were synthesized via the resolution of their corresponding camphorsulfonates of the racemates. The absolute configurations of (+) -1, (+) -2 and (−) -2 were assigned as (a R) and (a S), respectively, by the X-ray analysis and CD spectrum.
    通过拆分外消旋体的相应樟脑磺酸盐,合成了光学纯的二聚体O- demethylmurrayafoline A(1)及其6,6'-二甲氧基类似物2。通过X射线分析和CD光谱,将(+)- 1,(+)- 2和(-)- 2的绝对构型分别指定为(a R)和(a S)。
  • Oxidative aryl coupling reactions: a biomimetic approach to configurationally unstable or axially chiral biaryl natural products and related bioactive compounds
    作者:Gerhard Bringmann、Stefan Tasler
    DOI:10.1016/s0040-4020(00)00940-6
    日期:2001.1
    products and related compounds in the fields of biphenyls, biscarbazoles and bisnaphthylisoquinolines. For sterically more hindered biaryls, which consequently show the phenomenon of axial chirality, the products were prepared in an atropisomerically pure form. Their absolute axial configurations were assigned mainly by experimental and computational CD investigations.
    酚和非酚氧化芳基偶联反应已成功用于联苯,双咔唑和双萘基异喹啉领域的各种天然产物和相关化合物的有效合成中。对于在空间上更受阻的联芳基,其因此表现出轴向手性现象,将产物制备为阻转异构纯形式。它们的绝对轴向构型主要通过实验和计算CD研究确定。
  • Bismurrayaquinone A: Synthesis, chromatographic enantiomer resolution, and stereoanalysis by computational and experimental CD Investigations
    作者:Gerhard Bringmann、Alfons Ledermann、Martin Stahl、Klaus—Peter Gulden
    DOI:10.1016/0040-4020(95)00528-g
    日期:1995.8
    The first total synthesis of a naturally occurring dimeric carbazole alkaloid, bismurrayaquinone A (4), is described, by oxidation of dimeric O-demethylmurrayafoline A, a still hypothetic natural product recently synthesized. By chromatography on a chiral phase, the two atropoenantiomers were separated. The absolute configurations of these two rotational isomers were elucidated by comparison of their calculated spectra with those measured experimentally.
  • Dimeric Murrayafoline A, a potential Bis-Carbazole Alkaloid: 'Biomimetic' Synthesis, Atropoisomer Separation, and Antimalarial Activity
    作者:Gerhard Bringmann、Alfons Ledermann、Guido François
    DOI:10.3987/com-94-s30
    日期:——
    The first total synthesis of a (potential) dimeric carbazole alkaloid is described. After an improved preparation of the monomeric building block, ''biomimetic dimerization'' by oxidative phenolic coupling was best achieved with di-terf-butyl peroxide in chlorobenzene, leading to a highly selective formation of the 2,2'-coupled ''dimer'', the parent framework of several naturally occurring dimeric carbazole alkaloids. For the atropo-enantiomer analysis, a chromatographic procedure on a chiral phase was developed. Both the mono- and the dimeric phenolic carbazoles displayed in vitro antimalarial activity against Plasmodium falciparum.
