  简便的微波和SnCl 2合成2,3-二氢喹唑啉-4（1H）-ones

  摘要：

  据报道，具有生物学重要性的支架2，3-二氢喹唑啉-4（1 H）-ones是一种优雅，简单，轻便且健壮的方法。1％SnCl 2催化/微波介导的方法提供了纯净的物质，在120°C的微波照射20分钟后通过冷却和过滤收集。总共制备了41种类似物，分离产率为17–99％。该过程对脂肪族，芳香族，杂环和无环醛具有很高的耐受性，但是呋喃，吡咯和噻吩醛的反应性与亲电子加成和/或Diels-Alder加成的倾向相关。结果，噻吩提供了高产率（80％），而吡咯羧醛没有反应。具有简单的肉桂醛，并在SbCl 3中介导的反应，并与α，β-不饱和醛等价的喹唑啉-4（3 H）-一个，而不是2,3-二氢喹唑啉-4（1 H）-一个。

  In this study, series of ring-substituted 2-styrylquinazolin-4(3H)-one and 4-chloro-2-styrylquinazoline derivatives were prepared. The syntheses of the discussed compounds are presented. The compounds were analyzed by RP-HPLC to determine lipophilicity. They were tested for their inhibitory activity on photosynthetic electron transport (PET) in spinach (Spinacia oleracea L.) chloroplasts. Primary in vitro screening of the synthesized compounds was also performed against four mycobacterial strains and against eight fungal strains. Several compounds showed biological activity comparable with or higher than that of the standard isoniazid. It was found that the electronic properties of the R substituent, and not the total lipophilicity of the compound, were decisive for the photosynthesis-inhibiting activity of tested compounds.

  本研究制备了一系列环取代的 2-苯乙烯基喹唑啉-4(3H)-酮和 4-氯-2-苯乙烯基喹唑啉衍生物。文中介绍了所讨论化合物的合成方法。化合物通过 RP-HPLC 进行分析，以确定其亲油性。测试了这些化合物对菠菜叶绿体光合电子传递（PET）的抑制活性。此外，还针对四种分枝杆菌菌株和八种真菌菌株对合成的化合物进行了体外初筛。一些化合物显示出与标准异烟肼相当或更高的生物活性。研究发现，R 取代基的电子特性，而不是化合物的总亲油性，对测试化合物的光合作用抑制活性起着决定性作用。

  A group of styrylazanaphthalenes and azanaphthalenediones were synthesized and tested for their anti-proliferative activity. Most of the compounds were obtained with the use of microwave-assisted synthesis. The lipophilicity of the compounds was measured by RP-HPLC and their anti-proliferative activity was assayed against the human SK-N-MC neuroepithelioma and HCT116 human colon carcinoma cell lines. Active compounds were also tested in clonogenity and comet assays. Several quinazolinone and styrylquinazoline analogues were found to have markedly greater anti-proliferative activity than desferoxamine and cis-platin. (C) 2010 Elsevier Ltd. All rights reserved.
