Abstract
Introduction of beta-galactosidase into a trans-sialidase reaction, i.e. sialic acid transfer reaction from a donor substrate (alpha2,3-sialyllactose) to an acceptor substrate (beta-galactosyldisaccharide), could improve the yield of desired sialylated trisaccharide by hydrolyzing lactose, a byproduct from the donor. When trans-sialidase reaction was performed with stoichiometric amounts (2 mM) of alpha2,3-sialyllactose and Galbeta(1,3)GlcNAc, the yield of NeuAcalpha(2,3)Galbeta(1,3)GlcNAc increased from 45% to 75% by the coupling of Escherichia coli beta-galactosidase. Furthermore, by changing the substrate ratio in the coupled reaction, i.e. two-fold excess of alpha2,3-sialyllactose to Galbeta(1,3)GlcNAc, above 95% of yield was achieved based on the amount of Galbeta(1,3)GlcNAc. However, two-fold excess of Galbeta(1,3)GlcNAc to alpha2,3-sialyllactose in this reaction was more desirable for the purification of NeuAcalpha(2,3)Galbeta(1,3)GlcNAc, since complete consumption of alpha2,3-sialyllactose was achieved. Efficiency of the coupled reaction was affected by the specificity of beta-galactosidase for acceptor substrate. When Galbeta(1,6)GlcNAc was used as the acceptor, E. coli beta-galactosidase hydrolyzed Galbeta(1,6)GlcNAc as well as lactose in the coupled reaction, resulting in a significant decrease in the yield of desired sialylated trisaccharide. The conversion yield of the sialylation of Galbeta(1,6)GlcNAc could be improved by employing Bacillus circulans beta-galactosidase.

Abstract
Previous syntheses of ganglioside GM3 (NeuAc alpha3Gal beta4Glc beta1Cer) are reviewed, and both chemoenzymatic and chemical total synthetic approaches were investigated. In a chemoenzymatic approach, (2S,3R,4E)-5'''-acetyl-alpha-neuraminyl-(2''' --> 3'')-beta-galactopyranosyl-(1'' --> 4')-beta-glucopyranosyl-(1' <--> 1)-2-azido-4-octadecene-1,3-diol (azidoGM3) was readily prepared utilizing recombinant beta-Gal-(1'' --> 3'/4')-GlcNAc alpha-(2''' --> 3'')-sialyltransferase enzyme, and was evaluated as a synthetic intermediate to ganglioside GM3. The chemical total synthesis of ganglioside GM3 was performed on one of the largest scales yet reported. The highlights of this synthesis include minimizing the steps necessary to prepare the lactosyl acceptor as a useful anomeric mixture, which was present in excess for the highly regioselective and fairly stereoselective sialylation with a known neuraminyl donor to give the protected GM3 trisaccharide. The synthetic methodology maximized convergence by a subsequent glycosidic coupling of the well-characterized GM3 trisaccharide trichloroacetimidate derivative with protected ceramide. The ganglioside GM3 was nearly homogeneous as the two glycosidic couplings utilized preparative HLPC purifications, and variations in the sphingosine base and fatty acyl group were under 0.1 and 0.2%, respectively.

Abstract
In the present work, the combination of chemical and enzymatic methods to obtain neoglycoproteins is described. Three bovine serum albumin (BSA)-conjugates, BSA-[GalNAc alpha-], BSA-[Gal(beta 1-3)GalNAc(alpha-], and BSA-[Neu5Ac(alpha 2-3)Gal(beta 1-3)GalNAc(alpha-], were prepared. alpha GalNAc derivatives were galactosylated employing crude beta-galactosidase from bovine testes. The use of oversaturated donor solutions (pNP beta Gal) enhanced the yields up to 60%. This method was verified using divalent structures as acceptors, that rendered di- and tri-galactosylated products. Further treatment of the disaccharides with CMP-Neu5Ac and alpha 2-3 sialyltransferase from pork liver led to formation of trisaccharides. Finally, mono-, di-, and trisaccharides were coupled to BSA employing a thiolic group introduced into the protein for Michael addition to a maleinimide group in the spacer-arm of the saccharide components. The results were monitored by HPLC and MALDI-TOF.

Abstract
Recombinant alpha(2-3)sialyl-transferase from rat liver is used to sialylate a series of type-I (Lewisc) disaccharides on a preparative scale. The enzyme tolerates a broad array of N-acetyl replacements of the N-glucosamine subunit ranging from small and large lipophilic groups to charged and heterocyclic amides.

Abstract
In search of substrate analogues for the porcine liver beta-D-Gal p-(1-->3)-D-Gal p-NAc: CMP-Neu5Ac-(2-->3')-alpha-sialyltransferase, three disaccharides beta-D-Gal p-(1-->3)-beta-D-Gal p-O-CH3 (5), beta-D-Gal p-(1-->3)-beta-D-(2-OAc)-Gal p-O-CH3 (7) and beta-D-Gal p-(1-->3)-beta-D-(2-OAc)-Gal p-O-Bn (11) were synthesized and tested with the enzyme. Disaccharide 7 turned out to be a very good substrate allowing a rapid access to the trisaccharide alpha-Neu5Ac-(2-->3)-beta-D-Gal p-(1-->3)-beta-D-(2-OAc)-Gal p-O-CH3 (13) on a preparative scale using the crude enzyme immobilized on cationic exchanger. Trisaccharide 13 was further exploited, first as a sialyl donor in Trypanosoma cruzi trans-sialidase catalyzed reaction and second through acetolysis reaction as a source for the synthon alpha-Neu5Ac-(2-->3)-D-Gal (16).

Abstract
New glycosides derived from ergot alkaloids elymoclavine and DH-lysergol were synthesized by chemoenzymatic methods. beta-Glucosides were obtained either by chemical method or by transglycosylation (glycosidase from Aspergillus oryzae), lactosides were prepared by further extension of carbohydrate chain using beta-1,4-galactosyltransferase (bovine milk) and alpha-5-N-acetylneuraminyl-(2-->6)-beta-D-galactopyranosyl-(l-->4)-2- acetamido-2-deoxy-beta-D-glucopyranosyl-(1-->O)-elymoclavine was prepared using alpha-2,6-sialyltransferase (rat liver). Immunomodulatory activity of elymoclavine and 9,10-dihydrolysergol and their glycosylated derivatives on natural killer (NK) cell-mediated cytotoxicity of human resting and activated human peripheral blood mononuclear cells (PBMC) was investigated. Addition of ergot alkaloid glycosides to the mixtures of effector and target cells potentiated the PBMC cytotoxicity against both NK-sensitive and -resistant target cells. The glycoconjugates of elymoclavine enhanced cytotoxicity of PBMC against NK-resistant target cells. The glycoconjugates of DH-lysergol potentiated NK cytotoxicity of PBMC against NK-sensitive target cells.

Abstract
The application of glycosyltransferases to the chemoenzymatic synthesis of neoglycosphingolipids and lipid-linked oligosaccharides allows the regio- and stereoselective formation of glycosidic bonds. In our laboratory galactosyl-, sialyl-, and fucosyltransferases have been used to assemble oligosaccharide headgroups directly on a sphingosine derivative without the need for any protection group strategies, including the Lewisx antigen. In complementary studies on N-linked oligosaccharide biosynthesis, chemically phosphorylated dolichol analogues have been tested as substrates for Dol-P-Man synthetase. Also, the substrate recognition of the core beta-1,4-mannosyltransferase from yeast has been investigated using a range of chitobiose derivatives as potential substrates.

Abstract
N-Glycolylglucosamine 8 was synthesized in 4 steps from anisal glucosamine, via the new crystalline monochloracetyl derivatives 3, 4 and 7. N-Glycolylneuraminic acid 10 was prepared in 59% yield starting from pyruvate and a mixture of 8 and its manno epimer 9 in a 2:3 ratio, with immobilized sialic acid aldolase. Neu5Gc 10 was converted into CMP-NeuGc 11 in the presence of immobilized calf brain CMP-sialate synthetase. Finally 11 was used as a donor in the transfer to the acceptor beta-D-Gal-(1-3)-beta-D-GalNAc-OBn 12 catalyzed by a preparation of porcine liver (2-3)-alpha-sialyltransferase, roughly purified by a chromatography on Cibacron Blue-agarose. alpha-Neu5Gc-(2-3)-beta-D-Gal-(1-3)-beta-D-GalNac-OBn 13 isolated in 56% yield was deprotected to give the non-reducing terminal sequence of GM1b glycolylated ganglioside, which might be expressed in human tumors.

Abstract
N-Acetyl-lactosamine(beta-D-Gal p-(1-->4)-D-Glc pNAc) was synthesized regioselectively with the aid of the transglycosylation activity of beta-galactosidase isolated from Diplococcus pneumoniae using p-nitrophenyl beta-D-galactopyranoside as the donor. Also, transglycosylation of the sialyl group in an alpha-(2-->8)-linked sialic acid dimer or p-nitrophenyl glycoside of sialic acid to N-acetyl-lactosamine was performed using sialidases of various origins. When sialidase from Clostridium perfringens, Arthrobacter ureafaciens, or Vibrio cholerae was used, alpha-(2-->6)-linked sialyl N-acetyl-lactosamine was obtained regioselectively. In contrast, when sialidase from newcastle disease virus was used, the alpha-(2-->3)-linked isomer was obtained regioselectively. The regioselectivity of the transglycosylation reaction using beta-galactosidase and sialidase was compared with hydrolysis specificity toward the same linkages.
