As a part of our continuing search for bioactive constituents from Brassicaceae family, three new bis-thioglycosides (1-3) were isolated from the 80% MeOH extract of Nasturtium officinale, together with 13 known compounds (4-16). The chemical structures of three new bis-thioglycosides (1-3) were elucidated using NMR techniques (1H and 13C NMR, 1H-1H COSY, HSQC, and HMBC), HRESIMS, and a chemical method
作为我们不断寻找的十字花科植物生物活性成分的一部分,从金盏花的80%MeOH提取物中分离了三种新的双硫代糖苷(1-3),以及13种已知化合物(4-16)。使用NMR技术(1H和13C NMR,1H-1H COSY,HSQC和HMBC),HRESIMS和化学方法阐明了三种新的双硫代糖苷(1-3)的化学结构。评估了所有化合物对脂多糖(LPS)刺激的鼠小神经胶质BV-2细胞中一氧化氮(NO)水平的抑制作用。在分离物中,化合物5显示出对NO产生的强抑制作用,化合物4和15显示出中度的抑制活性,表明来自N.officinale的双硫代糖苷的神经保护和抗神经炎作用。
