  Antiviral Agents. I. Synthesis and Antiviral Evaluation of Trimeric Naphthoquinone Analogues of Conocurvone

  摘要：

  Conocurvone 是一种从澳大利亚特有灌木 Conosperum sp.（原生植物科）中分离出来的新型天然产物，具有抗艾滋病毒的活性，但它是一种高亲脂性化合物，这表明它的水溶性和生物利用度可能存在问题。本文介绍了一种利用 2-羟基萘醌和 2,3-二卤醌缩合合成三聚萘醌的通用简便方法。报告还介绍了应用这种方法合成一系列更简单、亲油性更低的三聚萘醌简单类似物 conocurvone 及其抗 HIV 活性。

  Novel 2-hydroxy-3-nitro-1,4-naphthoquinones were synthesized by an improved method utilizing nitronium tetrafluoroborate in high yields. A subsequent conversion to 2-chloro-3-nitro-1,4-naphthoquinones and a substitution of the chlorine by hydroxyquinone anions yielded 3-nitro-2,2‘-binaphthoquinones with a complete regiocontrol.

  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.
