Abstract
A new amino sugar named eremosamine was isolated from hydrolysate of eremomycin, an antibiotic belonging to the group of polycyclic glycopeptides. Crystalline derivatives of the amino sugar i. e. methyleremosaminide and methyl-N,O-acetyleremosaminide (alpha- and beta-anomers) were prepared. The data on PMR study and optic properties of the compounds showed that eremosamine had the structure of 2,3,6-tridesoxy-3-amino-3-C-methyl-L-arabinohexose.
摘要
从多环糖肽类抗生素埃瑞莫霉素的水解产物中分离出一种名为埃瑞莫胺的新氨基糖。制备了该氨基糖的结晶衍生物，即甲基埃瑞莫胺和甲基 - N,O - 乙酰基埃瑞莫胺（α - 和β - 异头物）。化合物的核磁共振氢谱（PMR）研究数据和光学性质表明，埃瑞莫胺具有2,3,6 - 三脱氧 - 3 - 氨基 - 3 - C - 甲基 - L - 阿拉伯己糖的结构。
