combination of N-acetyl glucosamine, 2,3-dihydroxypropanoic acid, and an alkyl amine with a C16 or C17 hydrocarbon chain primarily based on 1D and 2D NMR and mass spectroscopic data. The exact location of the olefinic double bond in deinococcucins C and D (3 and 4) was assigned based on the liquid chromatography–mass spectroscopy data obtained after olefin metathesis. The absolute configurations of the N-acetyl
四个新aminoglycolipids,deinococcucins A-d(1 - 4),从已发现的异常球菌属。从女王木匠蚂蚁Camponotus japonicus的肠中分离出的菌株。主要基于1D和2D NMR和质谱数据,阐明了脱inocoucucins A–D的结构为N-乙酰基葡糖胺,2,3-二羟基丙酸和具有C 16或C 17烃链的烷基胺的组合。脱链球菌C和D中烯烃双键的确切位置(3和4)是根据烯烃复分解后获得的液相色谱-质谱数据分配的。N-乙酰氨基葡萄糖和2,3-二羟基部分的绝对构型分别通过真实样品和苯甘氨酸甲酯衍生产品的气相色谱-质谱分析确定。Deinococcucins A和C在小鼠Hepa-1c1c7细胞中显示出显着的醌还原酶诱导作用。
