these limitations in case of 2′-hydroxychalcones through bioisosteric substitution of fluoro groups in place of phenolic hydroxyls. The fluorinated chalcones were found to be more potent antioxidant and anti-proliferative compounds than their hydroxyl counterparts indicating the influence of metabolically stable C–F bonds towards bioavailability. The difluoro derivatives were found to be most effective
查耳酮参与类黄酮的合成,其本身已知具有多种药理特性。但是,与其他结构相似的植物化学物质(如藤黄酚和姜黄素)相比,查耳酮的治疗用途受到限制,因为它们的生物利用度较低,并且可以从生物系统中快速清除新陈代谢。在目前的工作中,我们试图通过氟的生物等位取代酚羟基来克服2'-羟基查耳酮的这些局限性。发现氟化查耳酮比羟基查耳酮更有效的抗氧化剂和抗增殖化合物,表明代谢稳定的CF键对生物利用度的影响。
