  摘要：

  一系列新颖的3-芳基-4-羟基-2(5H) 呋喃酮-丙烯酸酯混合物是基于天然丁内酯和丙烯酸酯骨架设计和合成的。所制备化合物的结构经过1H-NMR、13C-NMR和电喷雾电离质谱（ESI-MS）表征，对目标化合物对十二种植物病原真菌的生物活性进行了研究。初步的体外抗真菌活性筛选显示，大多数目标化合物在浓度为100 mg·L−1时对各种病原真菌有中等抑制作用，并表现出广谱抗真菌活性。进一步研究还表明，化合物7e和7k在较低浓度下仍对油菜植物上的茶树萎凋病、软腐病和赤霉病菌有一定的抑制活性，可作为进一步研究的次级引物进行优化。

  A variety of 3-aryl tetronic acids have been synthesized by an undirected, intermolecular C–H functionalization of arenes with 3-diazofuran-2,4-dione. This methodology featured as a key step in the synthesis of a series of naturally occurring 3-aryl-5-arylidene tetronic acids (pulvinates) from commercially available tetronic acid. Salient features of the pulvinic acid synthesis include a one-step,

  3-Arylfuran-2(5H)-one derivatives show good antibacterial activity and were determined as tyrosyl-tRNA synthetase (TyrRS) inhibitors. In a systematic medicinal chemistry exploration, we demonstrated chemical opportunities to treat infections caused by Helicobacter pylori. Twenty 3-arylfuran-2(5H)-ones were synthesized and evaluated for anti-H. pylori, antioxidant and anti-urease activities which are closely interconnected with H. pylori infection. The results displayed that some of the compounds show excellent antioxidant activity, and good anti-H. pylori and urease inhibitory activities. Out of these compounds, 3( 3-methylphenyl) furan-2(5H)-one (b9) showed the most potent antioxidant activity (IC50 = 8.2 mu M) and good anti-H. pylori activity (MIC50 = 2.6 mu g/mL), and it can be used as a good candidate for discovering novel anti-gastric ulcer agent.

  A series of novel 3-aryl-4-hydroxy-2(5H) furanone-acrylate hybrids were designed and synthesized based on the natural butenolides and acrylates scaffolds. The structures of the prepared compounds were characterized by 1H-NMR, 13C-NMR and electrospray ionization mass spectrometry (ESI-MS), and the bioactivity of the target compounds against twelve phytopathogenic fungi was investigated. The preliminary in vitro antifungal activity screening showed that most of the target compounds had moderate inhibition on various pathogenic fungi at the concentration of 100 mg·L−1, and presented broad-spectrum antifungal activities. Further studies also indicated that compounds 7e and 7k still showed some inhibitory activity against Pestallozzia theae, Sclerotinia sclerotiorum and Gibberella zeae on rape plants at lower concentrations, which could be optimized as a secondary lead for further research.

  Tyrosyl-tRNA synthetase (TyrRS) is an aminoacyl-tRNA synthetase family protein that possesses an essential role in bacterial protein synthesis. The synthesis, structure-activity relationship, and evolution of a novel series of adenosine-containing 3-arylfuran-2(5H)-ones as TyrRS inhibitors are described. Advanced compound d3 from this series exhibited excellent affinity for TyrRS with IC50 of 0.61
