A series of neoglycoconjugates derived from deoxynojirimycin has been prepared by click connection with functionalised adamantanes. They have been assayed as glycosidase inhibitors, as inhibitors of the glycoenzymes relevant to the treatment of Gaucher disease, as well as correctors of the defective ion-transport protein involved in cystic fibrosis. We have demonstrated that it is possible to selectively either strongly inhibit ER-α-glucosidases and ceramide glucosyltransferase or restore the activity of CFTR in CF-KM4 cells by varying the length of the alkyl chain linking DNJ and adamantane.
通过点击连接功能化的金刚烷,制备了一系列来自脱氧诺吉苷的neoglycoconjugate。它们已被测评为糖苷酶抑制剂、戈谢病治疗相关糖酶的抑制剂,以及囊性纤维化中涉及的缺陷离子转运蛋白的校正剂。我们证明了通过改变DNJ和金刚烷之间连接的烷基链长度,可以有选择性地强有力抑制ER-α-葡萄糖苷酶和神经酰胺葡萄糖基转移酶,或恢复CF-KM4细胞中CFTR的活性。
