摘要: 本文旨在提高根皮素的生物活性,以其作为母体通过与异烟肼结合引入C=NNH活性基团,合成了一种新型酰腙类化合物。采用UV,IR,1H NMR,13C NMR及元素分析等手段对产物进行结构表征,并测定了根皮素及其异烟酰基腙的还原能力,清除DPPH自由基及清除ABTS自由基能力。结果表明根皮素异烟酰基腙的抗氧化活性显著优于根皮素。

Abstract: To improve the biological activity of phloretin, a novel hydrazone was synthesis with phloretin and isoniazid,and the target compound was characterized by UV, IR, 1H NMR, 13C NMR and elemental analysis, respectively.Reducing power, DPPH and ABTS•+ radical scavenging assays were carried out to evaluate the antioxidant and free radical scavenging abilities of phloretin and its hydrazone. The results showed that the antioxidant and free radical scavenging abilities of hydrazone was stronger than phloretin.

Key words: hydrazone, phloretin, isoniazid, synthesis, antioxidant activity
