Honokiol, a natural polyphenol, which was reported to have satisfactory influenza neuraminidase (NA) inhibitory activity, was structurally modified. Twenty-three compounds were synthesized and the ortho-effects in the epoxidation and hydrolyzation reactions were studied. The derivatives were evaluated for NA inhibitory activity and the benzoylhydrazone derivatives showed much better anti-NA activity
厚朴酚,一种天然多
酚,据报道具有令人满意的流感
神经氨酸酶(NA)抑制活性,经过结构修饰。合成了二十三种化合物,并研究了其在环氧化和
水解反应中的邻位作用。评价了衍
生物的NA抑制活性,并且苯甲酰derivatives衍
生物显示出比
厚朴酚更好的抗NA活性。构效关系分析表明,多
酚类化合物比单
酚类和双
酚类具有更好的抗NA活性。此外,药物与靶标的可能结合模式显示,与
厚朴酚相比,活性最高的化合物与NA的活性位点具有更强的相互作用,表明其具有强大的抗流感病毒活性。
