The physicochemical properties and antioxidant activity of a molecule could be improved by the substitution of an oxygen atom in a molecule with selenium. We synthesized selenoflavanones and flavanones to evaluate their neuroprotective effects. The selenoflavanones showed improved physicochemical properties, suggestive of the ability to pass through the blood-brain barrier (BBB). They showed in vitro antioxidant effects against hydrogen peroxide, and did not result in severe cytotoxicity. Moreover, infarction volumes in a transient ischemia mouse model were significantly reduced by the selenoflavanone treatments.
用硒取代分子中的氧原子可以改善分子的理化性质和抗氧化活性。我们合成了硒黄烷酮和黄烷酮,以评估它们的神经保护作用。硒黄烷酮显示出更好的理化特性,表明它们能够通过血脑屏障(BBB)。它们在体外对过氧化氢具有抗氧化作用,而且不会产生严重的细胞毒性。此外,硒黄烷酮还能显著减少瞬时缺血小鼠模型的梗死体积。
