1-Deoxynojirimycins with dansyl capped N-substituents as probes for Morbus Gaucher affected cell lines
摘要:
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.

Widescale evaluation of interacting partners for carbohydrates is an underexploited area. Probing of the ‘glyco-interactome’ has particular relevance given the lack of direct genetic control of glycoconjugate biosynthesis. Here we design, create and utilize a natural product-derived glycomimetic iminosugar probe in a Glycomimetic Affinity-enrichment Proteomics (Glyco-AeP) strategy to elucidate key interactions directly from mammalian tissue. The binding partners discovered here and the associated genomic analysis implicate a subset of chaperone and junctional proteins as important in male fertility. Such repurposing of existing therapeutics thus creates direct routes to probing in vivo function. The success of this strategy suggests a general approach to discovering ‘carbohydrate-active’ partners in biology.

Biotin-iminosugar conjugates of different configuration such as D-gluco, D-galacto, L-ido as well as a furanoid representative in the D-manno configuration have been synthesised and exhibit powerful inhibition of beta-glucosidase from Agrobacterium sp. with K(i) values in the range of the respective parent compounds. Such molecular probes have potential for activity-based protein pro. ling taking advantage of the biotin-(strept)avidin interaction. (C) 2010 Elsevier Ltd. All rights reserved.

The present invention provides a method for increasing the activity of a mutant or wild-type α-glucosidase enzyme in vitro and in vivo by contacting the enzyme with a specific pharmacological chaperone which is a derivative of 1-deoxynojirimycin. The invention also provides a method for the treatment of Pompe disease by administration of chaperone small molecule compound which is a derivative of 1-deoxynojirimycin. The 1-deoxynojirimycin derivative is substituted at the N or C1 position. Combination therapy with replacement α-glucosidase gene or enzyme is also provided.
