Abstract
The sulphation of Carbobenzoxyglucosamine by chlorosulphonic acid resulted in formation of N-carbobenzoxyglucosamine-4,6-disulphate. UDP-galactosamine 4-sulphate and glucosamine 4,6-disulphate were the competitive inhibitors of arylsulphatase B. Arylsulphatase B can hydrolyze UDP-galactosamine 4-sulphate and glucosamine 4,6-disulphate but not galactosamine 6-sulphate.
摘要
氯磺酸对苄氧羰基葡糖胺进行硫酸化反应生成了N - 苄氧羰基葡糖胺 - 4,6 - 二硫酸盐。UDP - 半乳糖胺4 - 硫酸盐和葡糖胺4,6 - 二硫酸盐是芳基硫酸酯酶B的竞争性抑制剂。芳基硫酸酯酶B能够水解UDP - 半乳糖胺4 - 硫酸盐和葡糖胺4,6 - 二硫酸盐，但不能水解半乳糖胺6 - 硫酸盐。
