    This invention provides various biquinone and trimeric quinone derivatives. The invention also provides a method for synthesis of a multi-quinone compound including reacting a hydroxyquinone anion with a first quinone possessing a first directing group at a C-2 of the first quinone and a second directing group at a C-3 of the first quinone and obtaining a biquinone having one of the first and second directing groups at a C-3 of a first quinone monomer and a hydroxyl group at a C-3′ of a second quinone monomer. The biquinone can be further reacted to obtain various biquinone derivatives or with a second hydroxyquinone anion to obtain trimeric quinone derivatives, including trimeric naphthoquinone derivatives. The biquinones and trimeric quinones of this invention demonstrate antiviral activity and can be used to treat viral infections, particularly HIV infections.
    本发明提供了各种二醌和三聚醌衍生物。本发明还提供了一种合成多醌化合物的方法,包括将羟基醌负离子与具有第一定向基位于第一醌的C-2处和第二定向基位于第一醌的C-3处的第一醌反应,并获得一种二醌,其中第一和第二定向基之一位于第一醌单体的C-3处,而羟基位于第二醌单体的C-3′处。二醌可以进一步反应以获得各种二醌衍生物,或与第二个羟基醌负离子反应以获得三聚醌衍生物,包括三聚萘醌衍生物。本发明的二醌和三聚醌表现出抗病毒活性,可用于治疗病毒感染,特别是HIV感染。

    Unsymmetrical biquinone and trimeric quinone derivatives were synthesized using halotriflate-biselectrophilic naphthoquinones through stepwise regioselective quinone substitution chemistry and evaluated for their ability to inhibit the cytopathogenic effects of HIV-1 using an MTT colorimetric assay. Compounds were also screened for their ability to inhibit the activity of HIV-1 integrase in vitro. Pyranylated trimeric quinones and biquinones exhibited both antiviral activity and integrase inhibitory activity. Conocurvone 1 and trimeric quinone 21 were the most potent HIV integrase inhibitors in the series. All of the biquinones showed HIV inhibitory activity. Simple methoxy substituted biquinones did not inhibit HIV-1 integrase. Published by Elsevier Ltd.

    Elemental Analysis, FTIR, 1 HNMR and EPR studies. The results reveal the coordination of alkali metals ‘Na’ and ‘K’ to lawsone anion. The single crystal X-ray structure of Lw - 6 was solved and it crystallizes in triclinic space group P-1 with extensive hydrogen bonding network of C H⋯O, N H⋯O and O H⋯O between cations and anions. Polycrystalline powder X-band EPR spectra of Lw - 1 to Lw - 5 shows signals

    日期:2002.2.1
    conocurvone is crucial for its potent anti-HIV activity. A new synthesis of trimeric quinones based on stepwise substitution of the halogens in 2,3-dihaloquinones by hydroxyquinone anions is described. Chlorinated biquinones are key intermediates that undergo regiospecific substitution reactions to yield trimeric quinone monomethyl ethers.
