  Lawsone萘醌衍生物的合成、表征及抗白血病特性

  摘要：

  萘醌被认为是抗癌药物分子的特殊结构。2-羟基-1,4-萘醌（劳松）与 1-溴-3-甲基-2-丁烯的赫克反应提供了容易获得拉帕酚的途径。几种天然存在的线性和角杂环醌类化合物（α-lapachone、β-lapachone、dunnione 和相关类似物）由拉帕酚制备。此外，我们证明合成萘醌可抑制人白血病 HL-60 细胞的细胞增殖。特别是，角型衍生物被发现具有中等的细胞毒性并提高细胞内谷胱甘肽二硫化物（GSSG）的水平。我们的工作突出了天然存在的角系列萘醌作为抗白血病药物的巨大潜力。

• Environmentally benign, one-pot synthesis of pyrans by domino Knoevenagel/6π-electrocyclization in water and application to natural products

  日期：——

  In water medium, environmentally benign, facile, and efficient synthesis of pyrans was achieved in good yields by the reactions of a variety of cyclic 1,3-dicarbonyls with several α,β-unsaturated aldehydes. The key strategy was a formal [3+3] cycloaddition by domino Knoevenagel/6π- electrocyclization. This methodology was applied to the synthesis of biologically interesting pyranocoumarin, pyranoquinolinone, and pyranonaphthoquinone derivatives along with selected natural and non-natural products.

  在水相介质中，通过多种环状1,3-二羰基化合物与若干α,β-不饱和醛的反应，以良好产率实现了吡喃的环保、简便、高效合成。关键策略是形式上的[3+3]环加成，通过多米诺Knoevenagel缩合/6π电环化反应实现。这一方法被应用于生物活性吡喃香豆素、吡喃喹啉酮和吡喃萘醌衍生物的合成，以及部分天然与合成产物的制备。

  In this study, we describe the synthesis of a series of alpha- and beta-lapachone containing hydroxyl or methoxyl groups on the benzene ring, by means of the selective acid promoted cyclization of the appropriate lapachol analog. The evaluation of the antiproliferative activity in human solid tumor cell lines provided 7-hydroxy-beta-lapachone as lead with enhanced activity over the parent drug beta-lapachone. Cell cycle studies, protein expression experiments, and reactive oxygen species analysis revealed that, similarly to beta-lapachone, ROS formation and DNA damage are critical factors in the cellular toxicity of 7-hydroxy-beta-lapachone.

  Naphthoquinones are considered privileged structures for anticancer drug molecules. The Heck reaction of 2‐hydroxy‐1,4‐naphthoquinone (lawsone) with 1‐bromo‐3‐methyl‐2‐butene offered easy access to lapachol. Several naturally occurring linear and angular heterocyclic quinoids (α‐lapachone, β‐lapachone, dunnione, and related analogues) were prepared from lapachol. Furthermore, we demonstrated that the
