Abstract

Cyclization by double reductive amination of d-xylo-hexos-5-ulose with methyl 6-aminohexanoate gave (methoxycarbonyl)pentyl-1-deoxynojirimycin. Reaction of the terminal carboxylic acid with N-dansyl-1,6-diaminohexane provided the corresponding chain-extended fluorescent derivative. By reaction with bis(6-dansylaminohexyl)amine, the corresponding branched di-N-dansyl compound was obtained. Both compounds are strong inhibitors of d-glucosidases and could also be shown to distinctly improve, at sub-inhibitory concentrations, the activity of beta-glucocerebrosidase in a Gaucher fibroblast (N370S) cell-line through chaperoning of the enzyme to the lysosome.

摘要

用甲基 6-氨基己酸对 d-木糖-5-戊酮进行双还原胺化环化,得到(甲氧基羰基)戊基-1-去氧野尻霉素。末端羧酸与 N-丹磺酰基-1,6-二氨基己烷反应,提供相应的链延伸荧光衍生物。通过与双(6-丹磺酰氨基己基)胺反应,得到相应的支化双 N-丹磺酰基化合物。这两种化合物都是 d-葡萄糖苷酶的强抑制剂,并且还可以通过将酶伴侣到溶酶体中,在亚抑制浓度下明显提高 Gaucher 成纤维细胞(N370S)细胞系中β-葡糖脑苷脂酶的活性。
