Abstract
Citronellyl- and solanesyl-based dolichol linked oligosaccharide (DLO) analogs were synthesized and tested along with undecaprenyl compounds for their ability to inhibit the release of [3H]OSP from [3H]DLO by mammalian liver DLO diphosphatase activity. Solanesyl (C45) and undecaprenyl (C55) compounds were 50-500 fold more potent than their citronellyl (C10)-based counterparts, indicating that the alkyl chain length is important for activity. The relative potency of the compounds within the citronellyl series was different to that of the solanesyl series with citronellyl diphosphate being 2 and 3 fold more potent than citronellyl-PP-GlcNAc2 and citronellyl-PP-GlcNAc, respectively; whereas solanesyl-PP-GlcNAc and solanesyl-PP-GlcNAc2 were 4 and 8 fold more potent, respectively, than solanesyl diphosphate. Undecaprenyl-PP-GlcNAc and bacterial Lipid II were 8 fold more potent than undecaprenyl diphosphate at inhibiting the DLODP assay. Therefore, at least for the more hydrophobic compounds, diphosphodiesters are more potent inhibitors of the DLODP assay than diphosphomonoesters. These results suggest that DLO rather than dolichyl diphosphate might be a preferred substrate for the DLODP activity.

Abstract
Targeting glycan-binding receptors is an attractive strategy for cell-specific drug and gene delivery. The C-type lectin asialoglycoprotein receptor (ASGPR) is particularly suitable for liver-specific delivery due to its exclusive expression by parenchymal hepatocytes. In this study, we designed and developed an efficient synthesis of carbohydrate-functionalized β-cyclodextrins (βCDs) and liposomes for hepatocyte-specific delivery. For targeting of ASGPR, rhodamine B-loaded βCDs were functionalized with glycodendrimers. Liposomes were equipped with synthetic glycolipids containing a terminal D-GalNAc residue to mediate binding to ASGPR. Uptake studies in the human hepatocellular carcinoma cell line HepG2 demonstrated that βCDs and liposomes displaying terminal D-Gal/D-GalNAc residues were preferentially endocytosed. In contrast, uptake of βCDs and liposomes with terminal d-Man or D-GlcNAc residues was markedly reduced. The d-Gal/d-GalNAc-functionalized βCDs and liposomes presented here enable hepatocyte-specific targeting. Gal-functionalized βCDs are efficient molecular carriers to deliver doxorubicin in vitro into hepatocytes and induce apoptosis.

Abstract
An anomeric phosphodiester linkage formed by a glycosyl phosphate unit and a hydroxyl group of another monosaccharide is found in many glycopolymers of the outer membrane in bacteria (e.g., capsular polysaccharides and lipopolysaccharides), yeasts and protozoa. The polymers (phosphoglycans) composed of glycosyl phosphate (or oligoglycosyl phosphate) repeating units could be chemically classified as poly(glycosyl phosphates). Their importance as immunologically active components of the cell wall and/or capsule of numerous microorganisms upholds the need to develop routes for the chemical preparation of these biopolymers. In this paper, we (1) present a review of the primary structures (known to date) of natural phosphoglycans from various sources, which contain glycosyl phosphate units, and (2) discuss different approaches and recent achievements in the synthesis of glycosyl phosphosaccharides and poly(glycosyl phosphates).

Abstract
Numerous carbohydrate-processing enzymes facilitate catalysis via stabilization of positive charges on or near the C-1, C-4, C-5, or C-6 positions. Substrate analogues differing only in the substitution of a fluorine for the axial C-5 hydrogen would possess reduced electron density at these positions and could be useful mechanistic probes of these enzymes. Introduction of this 5-fluoro substituent after radical halogenation was problematic because of the incompatibility of many protecting groups to the radical halogenation and the instability of the subsequent 5-fluoro hexosamines. Thus, to allow easy access to a wide variety of 5-fluoro glycosides and glycosyl phosphates, a versatile method for the introduction of the 5-fluoro group has been developed, the key step being the fluoridolysis of C-5, 6 epoxides. By use of this method, two fluorinated carbohydrates, uridine 5'-diphospho-5-fluoro-N-acetylglucosamine and octyl 5-fluoro-N-acetylglucosamine, have been synthesized. Initial biochemical investigations of these compounds show that 5-fluoro analogues are useful probes of transition-state charge development in several enzyme-catalyzed reactions.

Abstract
A total synthesis of lipid I (4), a membrane-associated intermediate in the bacterial cell wall (peptidoglycan) biosynthesis pathway, is reported. This highly convergent synthesis will enable further studies on bacterial resistance mechanisms and may provide insight toward the development of new chemotherapeutic agents with novel modes of action.

Abstract
Benzyl 2-acetamido-3,6-di-O-benzyl-2-deoxy-alpha-D-glucopyranoside was converted into its 4-O-(methylsulfonyl) derivative (2) by treatment with methanesulfonyl chloride in pyridine. Displacement of the methylsulfonyloxy group of 2 with fluoride ion afforded benzyl 2-acetamido-3,6-di-O-benzyl-2,4-dideoxy-4-fluoro-alpha-D-galactopyranosi de, which on hydrogenolysis, followed by acetylation, furnished 2-acetamido-1,3,6-tri-O-acetyl-2,4-dideoxy-4-fluoro-D-galactopyranose. Treatment of this and of 2-acetamido-1,3,4-tri-O-acetyl-2,6-dideoxy-6-fluoro-D-glucopyranose with trimethylsilyl trifluoromethanesulfonate in 1,2-dichloroethane at approximately 50 degrees afforded the 4-deoxy-4-fluoro- or the 6-deoxy-6-fluoro-oxazolines (5) and (11), respectively. Reaction of 5 and 11 with dibenzyl phosphate in 1,2-dichloroethane produced the alpha-linked dibenzyl phosphate derivatives 6 and 12, respectively. Catalytic hydrogenation of 6 provided 2-acetamido-3,6-di-O-acetyl-2,4-dideoxy-4-fluoro-alpha-D-galactopyranosy l phosphate (7), and that of 12 gave 2-acetamido-3,4-di-O-acetyl-2,6-dideoxy-6-fluoro-alpha-D-glucopyranosyl phosphate (13). Coupling of 7 and 13 with uridine 5'-monophosphomorpholidate in dry pyridine at approximately 37 degrees, followed by O-deacetylation, furnished the title compounds, respectively, isolated and characterized as their respective dilithium salts.

Abstract
Methyl 6-(ammonium 2-acetamido-2-deoxy-alpha-D-glucopyranosyl phosphate)-alpha-D-mannopyranoside was synthesized and identified by 1H-n.m.r. and 13C-n.m.r. data, acid hydrolysis, and elemental analysis. It was utilized for the determination of UDP-N-acetylglucosamine-1-phosphotransferase in an assay procedure that employed methyl alpha-D-mannopyranoside as an acceptor. The assay product was identified and characterized by thin-layer chromatography with the title reference compound. The present technique does not require [32P]UDP-N-acetylglucosamine, but effectively uses commercially available UDP-[14C]GlcNAc.

Abstract
Phosphoglycans from the cell wall of many strains of Streptococci contain terminal carbohydrate units linked by phosphodiester bridges to other residues of the glycans. In the immune response to phosphoglycans, the terminal carbohydrate-phosphate moieties function as antigenic determinants and induce the synthesis of antibodies with specificity for the glycosyl-phosphoryl units. It has now been found that such terminal carbohydrate units can be removed by treatment of the glycans with appropriate glycosidases. Thus, an almond beta-glucosidase releases glucose from a streptococcal Group D phosphoglycan with beta-glucosyl phosphate units, a jack bean N-acetyl-beta-glucosaminidase releases N-acetylglucosamine from a streptococcal Group L phosphoglycan with N-acetyl-beta-glucosaminyl phosphate units, and a rice alpha-glucosidase releases glucose from a yeast phosphoglycan with alpha-glucosyl phosphate units. The glycosidases also hydrolyze the hexose phosphates of the proper anomeric configuration and structure. The preparations of glycosidases used in this study exhibit specificity for single types of carbohydrate residues and are devoid of phosphatase and phosphodiesterase activities. The glycosidases act on glycosyl-phosphoryl linkages by a stereospecific mechanism and can therefore be used for the determination of the anomeric configuration of glycosyl-phosphoryl units of complex carbohydrates.
