better xanthine oxidase inhibitor with potential anti-gout properties, the studies on the fruit of Stauntonia brachyanthera were carried out, which led to the isolation of 12 glycosides, including 4 new nor-oleanane triterpenoids. Their structures were determined by comprehensive spectroscopic (NMR and HR MS) analysis. Two compounds (4 and 11) exhibited significant inhibitory activities on xanthine oxidase
为了找到一种更好的具有潜在抗痛风特性的黄嘌呤氧化酶抑制剂,进行了对苦参(Stauntonia brachyanthera)果实的研究,从而分离出12种糖苷,其中包括4种新的去甲油烷三萜。它们的结构是通过综合光谱(NMR和HR MS)分析确定的。两种化合物(4和11)对黄嘌呤氧化酶表现出显着的抑制活性,IC 50值分别为5.22和1.60 µM。另一种化合物(1,2,3,8和10)显示了合格的活动。结果表明,果实中存在正癸烷三萜和类黄酮对黄嘌呤氧化酶的抑制作用可能会阻止尿酸的产生。新型的领先的XO抑制剂正二十烷三萜类化合物,其分子生物学水平值得进一步研究。
