2-Acetamido-1,2-dideoxynojirimycin (2-ADN) is used as an inhibitor (transition analogue) to identify, purify, differentiate and characterized N-acetylglucosaminidase(s) (GlcNAcase). 2-Acetamido-1,2-dideoxynojirimycin is used as a ligand for the affinity purification of N-acetylglucosaminidases.

Most insect cells have a simple N-glycosylation process and consequently paucimannosidic or simple core glycans predominate. Previously, we have shown that paucimannosidic N-glycan structures are dominant in Drosophila S2 cells. It has been proposed that beta-N-acetylglucosaminidase (GlcNAcase), a hexosaminidase in
Human ovarian carcinoma (HOC) cell beta-N-acetylglucosaminidase (beta-NAG, EC 3.2.1.30) was found to be present in three isoenzymatic forms. All three forms were capable of degrading ECM. Therefore, inhibitors of beta-NAG were sought as potential anti-invasive agents. Two sugar analogs, 2-acetamido-2-deoxy-1,5-gluconolactone
The synthesis of 2-acetamido-1,2-dideoxynojirimycin (2-acetamido-1,2,5-tri-deoxy-1,5-imino-D-glucitol) by a double inversion procedure starting from 1-deoxynojirimycin is reported. The key intermediates were the selectively protected N-benzyl-1,5-dideoxy-1,5-imino-4,6-O-isopropylidene-D-mannitol, the triflate ester N-benzyl-3-O-benzyl-1,5-dideoxy-1,5-imino-4,6-O-isopropylidene-2-O- (tri-fluoromethylsulfonyl)-D-mannitol, and 2-azido-N-benzyl-3-O-benzyl-1,2,5-tri-deoxy-1,5-imino-4,6-O- isopropylidene-D-glucitol, readily obtained in a sequence from 1-deoxynojirimycin. Thus 1-deoxynojirimycin

alpha-N-Acetylglucosaminidase (EC 3.2.1.50) is a lysosomal enzyme that is deficient in the genetic disorder Sanfilippo syndrome type B. To study the human enzyme, we expressed its cDNA in Lec1 mutant Chinese hamster ovary (CHO) cells, which do not synthesize complex

Two N-acetylglucosaminidases were isolated from bovine kidney with a three step procedure featuring affinity purification on 2-acetamido-1,2,5-trideoxy-1,5-iminoglucitol (2-acetamido-1,2-dideoxynojirimycin, II). The major isoenzyme, Hex A, is an alpha, beta hetero-dimer (57 and 52 kDa) with isoelectric points from pH 5.3 to
