Abstract
Novel imidazole-containing boronic acid and palladium hybrid catalysis for regioselective O-allylation of carbohydrates has been developed. This catalytic process enables the introduction of a useful allyl functional group into the equatorial hydroxy group of cis-1,2-diols of various carbohydrates with low catalyst loading and excellent regioselectivities. This is the first report on hybrid catalysis in combination with a Lewis base-containing boronic acid and a transition metal complex.

Abstract
While the field of biocatalysis has bloomed over the past 20-30 years, advances in the understanding and improvement of carbohydrate-active enzymes, in particular, the sugar nucleotides involved in glycan building block biosynthesis, have progressed relatively more slowly. This perspective highlights the need for further insight into substrate promiscuity and the use of biocatalysis fundamentals (rational design, directed evolution, immobilization) to expand substrate scopes toward such carbohydrate building block syntheses and/or to improve enzyme stability, kinetics, or turnover. Further, it explores the growing premise of using biocatalysis to provide simple, cost-effective access to stereochemically defined carbohydrate materials, which can undergo late-stage chemical functionalization or automated glycan synthesis/polymerization.

Abstract
Background: Leishmaniasis, a vector-borne disease caused by the protozoan parasite from the genus Leishmania, is endemic to tropical and subtropical areas. Few treatments are available against leishmaniasis, with all presenting issues of toxicity, resistance, and/or cost. In this context, the development of new antileishmanial drugs is urgently needed. GDP-mannose pyrophosphorylase (GDP-MP), an enzyme involved in the mannosylation pathway, has been described to constitute an attractive therapeutic target for the development of specific antileishmanial agents. Methods: In this work, we produced, purified, and analyzed the enzymatic properties of the recombinant L. infantum GDP-MP (LiGDP-MP), a single leishmanial GDP-MP that presents mutation of an aspartate instead of an alanine at position 258, which is also the single residue difference with the homolog in L. donovani: LdGDP-MP. Results: The purified LiGDP-MP displayed high substrate and cofactor specificities, a sequential random mechanism of reaction, and the following kinetic constants: Vm at 0.6 µM·min−1, Km from 15–18 µM, kcat from 12.5–13 min−1, and kcat/Km at around 0.8 min−1µM−1. Conclusions: These results show that LiGDP-MP has similar biochemical and enzymatic properties to LdGDP-MP. Further studies are needed to determine the advantage for L. infantum of the A258D residue change in GDP-MP.

Abstract
Deoxy sugars represent an important class of carbohydrates, present in a large number of biomolecules involved in multiple biological processes. In various antibiotics, antimicrobials, and therapeutic agents the presence of deoxygenated units has been recognized as responsible for biological roles, such as adhesion or great affinity to receptors, or improved efficacy. The characterization of glycosidases and glycosyltranferases requires substrates, inhibitors and analogous compounds. Deoxygenated sugars are useful for carrying out specific studies for these enzymes. Deoxy sugars, analogs of natural substrates, may behave as substrates or inhibitors, or may not interact with the enzyme. They are also important for glycodiversification studies of bioactive natural products and glycobiological processes, which could contribute to discovering new therapeutic agents with greater efficacy by modification or replacement of sugar units. Deoxygenation of carbohydrates is, thus, of great interest and numerous efforts have been dedicated to the development of methods for the reduction of sugar hydroxyl groups. Given that carbohydrates are the most important renewable chemicals and are more oxidized than fossil raw materials, it is also important to have methods to selectively remove oxygen from certain atoms of these renewable raw materials. The different methods for removal of OH groups of carbohydrates and representative or recent applications of them are presented in this chapter. Glycosidic bonds in general, and 2-deoxy glycosidic linkages, are included. It is not the scope of this survey to cover all reports for each specific technique.

Abstract
Sufferers of cystic fibrosis are at significant risk of contracting chronic bacterial lung infections. The dominant pathogen in these cases is mucoid Pseudomonas aeruginosa. Such infections are characterised by overproduction of the exopolysaccharide alginate. We present herein the design and chemoenzymatic synthesis of sugar nucleotide tools to probe a critical enzyme within alginate biosynthesis, GDP-mannose dehydrogenase (GMD). We first synthesise C6-modified glycosyl 1-phosphates, incorporating 6-amino, 6-chloro and 6-sulfhydryl groups, followed by their evaluation as substrates for enzymatic pyrophosphorylative coupling. The development of this methodology enables access to GDP 6-chloro-6-deoxy-ᴅ-mannose and its evaluation against GMD.

Abstract
Bacterial cells present a wide diversity of saccharides that decorate the cell surface and help mediate interactions with the environment. Many Gram-negative cells express O-antigens, which are long sugar polymers that makeup the distal portion of lipopolysaccharide (LPS) that constitutes the surface of the outer membrane. This review highlights chemical biology tools that have been developed in recent years to facilitate the modulation of O-antigen synthesis and composition, as well as related bacterial polysaccharide pathways, and the detection of unique glycan sequences. Advances in the biochemistry and structural biology of O-antigen biosynthetic machinery are also described, which provide guidance for the design of novel chemical and biomolecular probes. Many of the tools noted here have not yet been utilized in biological systems and offer researchers the opportunity to investigate the complex sugar architecture of Gram-negative cells.

Abstract
Boronic acid-catalyzed regioselective Koenigs-Knorr-type glycosylation is presented. The reaction of an unprotected or partially protected glycosyl acceptor with a glycosyl halide donor in the presence of silver oxide and a low catalytic amount of imidazole-containing boronic acid was found to proceed smoothly, which enables construction of a 1,2-trans glycosidic linkage with high regioselectivities. This is the first example of the use of a boronic acid catalyst to initiate regioselective glycosylation via the activation of cis-vicinal diols in glycosyl acceptors.

Abstract
Sufferers of cystic fibrosis are at extremely high risk for contracting chronic lung infections. Over their lifetime, one bacterial strain in particular, Pseudomonas aeruginosa, becomes the dominant pathogen. Bacterial strains incur loss-of-function mutations in the mucA gene that lead to a mucoid conversion, resulting in copious secretion of the exopolysaccharide alginate. Strategies that stop the production of alginate in mucoid Pseudomonas aeruginosa infections are therefore of paramount importance. To aid in this, a series of sugar nucleotide tools to probe an enzyme critical to alginate biosynthesis, guanosine diphosphate mannose dehydrogenase (GMD), have been developed. GMD catalyzes the irreversible formation of the alginate building block, guanosine diphosphate mannuronic acid. Using a chemoenzymatic strategy, we accessed a series of modified sugar nucleotides, identifying a C6-amide derivative of guanosine diphosphate mannose as a micromolar inhibitor of GMD. This discovery provides a framework for wider inhibition strategies against GMD to be developed.

Iodoarene catalysts can be applied in versatile reactions, for instance in the construction of complex chiral molecules via dearomatization of simple aromatic compounds. Recently, we reported the synthesis of the first carbohydrate-based chiral iodoarene catalysts and their application in asymmetric catalysis. Here we describe the synthesis of some new and improved catalysts. An account on how we got to the improved catalyst design, as well as the X-ray structure of one of the carbohydrate-based iodoarenes, is given.

Abstract
The chemoenzymatic synthesis of a series of C6-modified GDP-d-Man sugar nucleotides is described. This provides the first structure-function tools for the GDP-d-ManA producing GDP-d-mannose dehydrogenase (GMD) from Pseudomonas aeruginosa. Using a common C6 aldehyde functionalization strategy, chemical synthesis introduces deuterium enrichment, alongside one-carbon homologation at C6 for a series of mannose 1-phosphates. These materials are shown to be substrates for the GDP-mannose pyrophosphorylase from Salmonella enterica, delivering the required toolbox of modified GDP-d-Mans. C6-CH3 modified sugar-nucleotides are capable of reversibly preventing GDP-ManA production by GMD. The ketone product from oxidation of a C6-CH3 modified analogue is identified by high-resolution mass spectrometry.

Abstract
The availability of nucleotide sugars is considered as bottleneck for Leloir-glycosyltransferases mediated glycan synthesis. A breakthrough for the synthesis of nucleotide sugars is the development of salvage pathway like enzyme cascades with high product yields from affordable monosaccharide substrates. In this regard, the authors aim at high enzyme productivities of these cascades by a repetitive batch approach. The authors report here for the first time that the exceptional high enzyme cascade stability facilitates the synthesis of Uridine-5'-diphospho-α-d-galactose (UDP-Gal), Uridine-5'-diphospho-N-acetylglucosamine (UDP-GlcNAc), and Uridine-5'-diphospho-N-acetylgalactosamine (UDP-GalNAc) in a multi-gram scale by repetitive batch mode. The authors obtained 12.8 g UDP-Gal through a high mass based total turnover number (TTNmass ) of 494 [gproduct /genzyme ] and space-time-yield (STY) of 10.7 [g/L*h]. Synthesis of UDP-GlcNAc in repetitive batch mode gave 11.9 g product with a TTNmass of 522 [gproduct /genzyme ] and a STY of 9.9 [g/L*h]. Furthermore, the scale-up to a 200 mL scale using a pressure operated concentrator was demonstrated for a UDP-GalNAc producing enzyme cascade resulting in an exceptional high STY of 19.4 [g/L*h] and 23.3 g product. In conclusion, the authors demonstrate that repetitive batch mode is a versatile strategy for the multi-gram scale synthesis of nucleotide sugars by stable enzyme cascades.

Abstract
Conventional mammalian models of neurodegeneration are often limited by futile axonogenesis with minimal functional recuperation of severed neurons. The emergence of zebrafish, a non-mammalian model with excellent neuroregenerative properties, may address these limitations. This study aimed to establish an adult zebrafish-based, neurotoxin-induced Parkinson's disease (PD) model and subsequently validate the regenerative capability of dopaminergic neurons (DpN). The DpN of adult male zebrafish (Danio rerio) were lesioned by microinjecting 6-hydroxydopamine (6-OHDA) neurotoxin (6.25, 12.5, 18.75, 25, 37.5, 50 and 100 mg/kg) into the ventral diencephalon (Dn). This was facilitated by an optimised protocol that utilised 1,1'-dioctadecyl-3,3,3',3'-tetramethyl-indocarbocyanineperchlorate (DiI) dye to precisely identify the injection site. Immunostaining was utilised to identify the number of tyrosine hydroxylase immunoreactive (TH-ir) DpN in brain regions of interest (i.e. olfactory bulb, telencephalon, preoptic area, posterior tuberculum and hypothalamus). Open tank video recordings were performed for locomotor studies. The Dn was accessed by setting the injection angle of the microinjection capillary to 60° and injection depth to 1200 μm (from the exposed brain surface). 6-OHDA (25 mg/kg) successfully ablated >85% of the Dn DpN (preoptic area, posterior tuberculum and hypothalamus) whilst maintaining a 100% survival. Locomotor analysis of 5-min recordings revealed that 6-OHDA-lesioned adult zebrafish were significantly (p < 0.0001) reduced in speed (cm/s) and distance travelled (cm). Lesioned zebrafish showed full recovery of Dn DpN 30 days post-lesion. This study had successfully developed a stable 6-OHDA-induced PD zebrafish model using a straightforward and reproducible approach. Thus, this developed teleost model poses exceptional potentials to study DpN regeneration.

Isolation of a methylated mannose-binding protein from terrestrial worm Enchytraeus japonensis. Glycoconj J 2017; 34:591-601. [PMID: 28577071 DOI: 10.1007/s10719-017-9778-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2017] [Revised: 05/12/2017] [Accepted: 05/24/2017] [Indexed: 12/21/2022]
Abstract
To elucidate a biological role of the methylated mannose residues found in N-glycans of terrestrial worm Enchytraeus japonensis, we first synthesized 3-O-methyl mannose- and 4-O-methyl mannose-derivatives and immobilized them to Sepharose 4B beads in order to isolate the sugar-binding protein. When whole protein extracts from the worms was applied to a series of the columns immobilized with the modified and unmodified mannose-derivatives, respectively, a protein with a molecular weight of 25,000 was isolated by 4-O-methyl mannose-immobilized column chromatography, and termed as a methylated mannose-binding protein (mMBP). mMBP bound weakly to a mannose-immobilized column and moderately to a 3-O-methyl mannose-immobilized column. The N-terminal amino acid sequences of mMBP and its endoprotease-digested peptides were determined. Using the degenerate first primers synthesized based on the primary sequence, a genomic DNA fragment was isolated. Then, the second primers were synthesized based on the genomic DNA fragment, and with use of them two cDNA fragments were obtained by the 3'- and 5'-RACE methods. Finally, the third primers were synthesized based on the sequences of the two cDNA fragments and one genomic DNA fragment, and with use of them a full-length cDNA of mMBP was isolated and shown to comprise a putative 633 bp open reading frame encoding 210 amino acid residues. BLAST analysis revealed that mMBP has identities by 26 ~ 55% to several proteins including the regeneration-upregulated protein 3 from the same species. Whether mMBP is involved in the regeneration of the worm is under investigation.
