• Preparative Monohydroxyflavanone Syntheses and a Protocol for Gas Chromatography-Mass Spectrometry Analysis of Monohydroxyflavanones

  single hydroxyl can be selectively added to a flavanone A- or B-ring at any position. We are also the first to develop a procedure that separates the seven isomers by GC and characterizes the mass spectra of the isomers. Both the synthetic method and the GC-MS conditions may become important tools during future flavanone metabolism and oxidation studies.

  我们描述了一种简便有效的制备方法，用于合成单羟基黄酮。使用该方案，每个合成在黄烷酮A环或B环的一个碳原子上区域选择性地引入羟基。七个可能的异构体分别由相应的单甲氧基甲氧基化2'-羟基查耳酮在酸性溶液中合成。使用包含DB-5毛细管柱的气相色谱-质谱（GC-MS）系统对这些单羟基黄酮进行了表征。我们的报道是制备合成方法的首次报道，在该合成方法中，可以在任何位置将单一羟基选择性地添加至黄烷酮A环或B环中。我们也是第一个开发通过GC分离7种异构体并表征这些异构体质谱的方法的公司。

  flavanones, which included polycyclic aromatic and heterocyclic rings, were readily synthesized via oxa-Michael addition from the corresponding hydroxychalcones with a catalytic amount of aqueous cesium fluoride solution under mild conditions. This method could be applied to the scalable synthesis of eriodictyol as a known potent inhibitor of the SARS-CoV-2 spike protein.

  在温和条件下，从相应的羟基查耳酮与催化量的氟化铯水溶液通过氧杂-迈克尔加成容易合成总共 36 种黄烷酮，其中包括多环芳环和杂环。该方法可用于作为 SARS-CoV-2 刺突蛋白的已知强效抑制剂圣草酚的可扩展合成。

  Novel chalcones were found as potent inhibitors of interleukin (IL)-5. 1-(2-Benzyloxy-6-hydroxyphenyl)-3-(4-hydroxyphenyl)-2-propen-1-one (2b, 78.8% inhibition at 50 mu M, IC50 = 25.3 mu M) was initially identified as a potent inhibitor of IL-5. This shows the compatible activity with budesonide or sophoricoside. To identify structural requirements, 26 chalcones were prepared and their inhibitory activities were tested against IL-5. Among them, compound 4-[(E)-3-(2-cyclohexylmethoxy-6-hydroxyphenyl)-3-oxoprop-1-enyl]benzenesulfonamide (2w, 99.5% inhibition at 50 mu M, IC50 = 1-8 mu M) shows the most potent activity. The important structural requirements of these chalcone analogs exhibiting the inhibitory activity against IL-5 were recognized as the following. (1) The hydrophobic group such as benzyloxy or cyclohexylmethoxy at 6-position of A ring is necessary. (2) The existence of phenolic hydroxyl at 6-position of A ring is critical. (3) Propenone unit as alpha,beta-unsaturated ketone is essential. (4) Electron withdrawing groups with hydrogen acceptor property at 4-position of B ring enhance the activity and quantitative structure-activity relationship of 2 regarding these substituents was determined.
