Abstract
Regular intake of fucosylated oligosaccharides has been associated with several benefits for human health, particularly for new-borns. Since these biologically active molecules can be found naturally in human milk, research efforts have been focused on the alternative synthetic routes leading to their production. In particular, utilization of fucosidases to perform stereoselective transglycosylation reactions has been widely investigated. Other reasons that bring these enzymes to the spotlight are their role in viral infections and cancer proliferation. Since their involvement in the pathogenesis of these diseases have been widely described, fucosidases have become a target in newly developed therapies. Finally, activity disorders of biologically important fucosidases can lead to health problems such as fucosidosis. What is common for both mechanisms is the interaction between the enzyme and substrates in and around the active site. Therefore, this review will analyse different substrate structures that have been tested in terms of their interaction with fucosidases active sites, either in synthesis or inhibition reactions. The published results will be compared from this perspective.

Abstract
Analogues of N‐butyl‐1‐deoxynojirimycin (NB‐DNJ) were prepared and assayed for inhibition of ceramide‐specific glucosyltransferase (CGT), non‐lysosomal β‐glucosidase 2 (GBA2) and the lysosomal β‐glucosidase 1 (GBA1). Compounds 5 a–6 f, which carry sterically demanding nitrogen substituents, and compound 13, devoid of the C3 and C5 hydroxy groups present in DNJ/NB‐DGJ (N‐butyldeoxygalactojirimycin) showed no inhibitory activity for CGT or GBA2. Inversion of stereochemistry at C4 of N‐(n‐butyl)‐ and N‐(n‐nonyl)‐DGJ (compounds 24) also led to a loss of activity in these assays. The aminocyclopentitols N‐(n‐butyl)‐ (35 a), N‐(n‐nonyl)‐4‐amino‐5‐(hydroxymethyl)cyclopentane‐ (35 b), and N‐(1‐(pentyloxy)methyl)adamantan‐1‐yl)‐1,2,3‐triol (35 f), were found to be selective inhibitors of GBA1 and GBA2 that did not inhibit CGT (>1 mm), with the exception of 35 f, which inhibited CGT with an IC50 value of 1 mm. The N‐butyl analogue 35 a was 100‐fold selective for inhibiting GBA1 over GBA2 (Ki values of 32 nm and 3.3 μm for GBA1 and GBA2, respectively). The N‐nonyl analogue 35 b displayed a Ki value of ≪14 nm for GBA1 inhibition and a Ki of 43 nm for GBA2. The N‐(1‐(pentyloxy)methyl)adamantan‐1‐yl) derivative 35 f had Ki values of ≈16 and 14 nm for GBA1 and GBA2, respectively. The related N‐bis‐substituted aminocyclopentitols were found to be significantly less potent inhibitors than their mono‐substituted analogues. The aminocyclopentitol scaffold should hold promise for further inhibitor development.

Abstract
Insight into the structure and inhibition mechanism of O-β-d-glucosidases by deoxa-pyranosylamine type inhibitors is provided by X-ray analysis of complexes between raucaffricine and strictosidine glucosidases and N-(cyclohexylmethyl)-, N-(cyclohexyl)- and N-(bromobenzyl)-β-d-gluco-1,5-deoxa-pyranosylamine. All inhibitors anchored exclusively in the catalytic active site by competition with appropriate enzyme substrates. Thus facilitated prospective elucidation of the binding networks with residues located at <3.9 Å distance will enable the development of potent inhibitors suitable for the production of valuable alkaloid glucosides, raucaffricine and strictosidine, by means of synthesis in Rauvolfia serpentina cell suspension cultures.

Abstract
Several C(1)-imino conjugates of D: -galactose, D: -lactose and D: -ribose, where the nitrogen center was substituted by the salicylidene or naphthylidene, were synthesized and characterized. Similar C(2)-imino conjugates of D: -glucose have also been synthesized. All the glyco-imino-conjugates, which are transition state analogues, exhibited 100% inhibition of the activity towards glycosidases extracted from soybean and jack bean meal. Among these, a galactosyl-napthyl-imine-conjugate (1c) showed 50% inhibition of the activity of pure alpha-mannosidase from jack bean at 22 +/- 2.5 microM, and a ribosyl-naphthyl-imine-conjugate (3c) showed at 31 +/- 5.5 microM and hence these conjugates are potent inhibitors of glycosidases. The kinetic studies suggested non-competitive inhibition by these conjugates. The studies are also suggestive of the involvement of aromatic, imine and carbohydrate moieties of the glyco-imino-conjugates in the effective inhibition. The binding of glyco-imino-conjugate has been established by extensive studies carried out using fluorescence emission and isothermal titration calorimetry. The conformational changes resulted in the enzyme upon interaction of these derivatives has been established by studying the fluorescence quench of the enzyme by KI as well as from the secondary structural changes noticed in CD spectra. All these studies revealed the difference in the binding strengths of the naphthylidene vs. salicylidene as well as galactosyl vs. lactosyl moieties present in these conjugates. The differential inhibition of these glyco-conjugates has been addressed by quantifying the specific interactions present between the glyco-conjugates and the enzyme by using rigid docking studies.

Abstract
Mannostatin A is a potent inhibitor of the mannose-trimming enzyme, Golgi alpha-mannosidase II (GMII), which acts late in the N-glycan processing pathway. Inhibition of this enzyme provides a route to blocking the transformation-associated changes in cancer cell surface oligosaccharide structures. Here, we report on the synthesis of new Mannostatin derivatives and analyze their binding in the active site of Drosophila GMII by X-ray crystallography. The results indicate that the interaction with the backbone carbonyl of Arg876 is crucial to the high potency of the inhibitor-an effect enhanced by the hydrophobic interaction between the thiomethyl group and an aromatic pocket vicinal to the cleavage site. The various structures indicate that differences in the hydration of protein-ligand complexes are also important determinants of plasticity as well as selectivity of inhibitor binding.

Abstract
The X-ray crystal structures of mannose trimming enzyme drosophila Golgi alpha-mannosidase II (dGMII) complexed with the inhibitors mannostatin A (1) and an N-benzyl analogue (2) have been determined. Molecular dynamics simulations and NMR studies have shown that the five-membered ring of mannostatin A is rather flexible occupying pseudorotational itineraries between 2T3 and 5E, and 2T3 and 4E. In the bound state, mannostatin A adopts a 2T1 twist envelope conformation, which is not significantly populated in solution. Possible conformations of the mannosyl oxacarbenium ion and an enzyme-linked intermediate have been compared to the conformation of mannostatin A in the cocrystal structure with dGMII. It has been found that mannostatin A best mimics the covalent linked mannosyl intermediate, which adopts a 1S5 skew boat conformation. The thiomethyl group, which is critical for high affinity, superimposes with the C-6 hydroxyl of the covalent linked intermediate. This functionality is able to make a number of additional polar and nonpolar interactions increasing the affinity for dGMII. Furthermore, the X-ray structures show that the environment surrounding the thiomethyl group of 1 is remarkably similar to the arrangements around the methionine residues in the protein. Collectively, our studies contradict the long held view that potent inhibitors of glycosidases must mimic an oxacarbenium ion like transition state.

Abstract
The cleavage of two sugar epoxides, methyl 2,3-anhydro-alpha-D-mannopyranoside and 2,3-anhydro-alpha-D-allopyranoside, with amines is presented as a method for preparing a library of 3-amino-sugars (methyl 3-amino-3-deoxy-alpha-D-altropyranosides and methyl 3-amino-3-deoxy-alpha-D-glucopyranosides) as potential glycosidase inhibitors. Several of the altropyranosides were micromolar inhibitors of bovine liver beta-galactosidase and almond beta-glucosidase. X-ray crystal structures were determined for one of the methyl 3-amino-3-deoxy-alpha-D-altropyranosides, 4t, and one of the methyl 3-amino-3-deoxy-alpha-D-glucopyranosides, 6d.

Abstract
Mannostatin and aminocyclopentitetrol analogues with various substitutions at the amino function were synthesized. These compounds were tested as inhibitors of human Golgi and lysosomal alpha-mannosidases. Modification of the amine of mannostatin had only marginal effects, whereas similar modifications of aminocyclopentitetrol led to significantly improved inhibitors. Ab initio calculations and molecular docking studies were employed to rationalize the results. It was found that mannostatin and aminocyclopentitretrol could bind to Golgi alpha-mannosidase II in a similar mode to that of the known inhibitor swainsonine. However, due to the flexibility of the five-membered rings of these compounds, additional low-energy binding modes could be adopted. These binding modes may be relevant for the improved activities of the benzyl-substituted compounds. The thiomethyl moiety of mannostatin was predicted to make favorable hydrophobic interactions with Arg228 and Tyr727 that would possibly account for its greater inhibitory activity.

Abstract
Aminocyclopentitol analogs of beta-D-glucose, beta-D-galactose and alpha-D-galactose bearing alkyl substituents as aglycon mimics on the amine function were prepared and tested for inhibition of various glycosidases. N-benzyl-beta-D-gluco derivatives 1-4 and N-benzyl-beta-D-galacto derivative 5 inhibited beta-galactosidase and beta-glucosidase. N-benzyl-alpha-D-galacto aminocyclopentitol 6 strongly inhibited alpha-galactosidase. The inhibitory activities observed were generally stronger compared to those of their primary amine analogs. A structure-activity relationship analysis was carried out including data from thirty-five different aminocyclopentitol glycosidase inhibitors. The strongest inhibitions reported for any enzyme were associated with a perfect stereochemical match between aminocyclopentitol and glycosidase, including the alpha- or beta-configuration of the amino-group corresponding to the enzyme's anomeric selectivity.

Abstract
The three-dimensional structure of glycosidases and of their complexes and the study of transition-state mimics reveal structural details that correlate with mechanism. Of particular interest are the transition-state conformations harnessed by individual enzymes and the substrate distortion observed in enzyme-ligand complexes. 3D-structure in synergy with transition-state mimicry opens the way for mechanistic interpretation of enzyme inhibition and for the development of therapeutic agents.

Abstract
[structure: see text] (1R,2R,3R,4R,5R)-4-Amino-5-methylcyclopentane-1,2,3 -tr iol 8, its 4S stereoisomer 9, and their acyclic analogues (R)- and (S)-2-aminobutanol 11 and 12 are selective but moderate inhibitors of alpha-L-fucosidases. N-Benzylation selectively enhances inhibition potency for aminocyclopentitol 8 (--> 1, K(i) = 6.8 x 10(-)(7) M) but decreases inhibition for its 4S-stereoisomer 9 (--> 2, K(i) = 1.1 x 10(-)(4) M) and for the aminobutanols 11 (--> 13, no inhibition) and 12 (--> 14, no inhibition).
