Abstract
We describe the synthesis together with the results of anti-HIV-1 activity and gp120-monolayer binding experiments of new galactosyl amphiphiles, analogues of galactosylceramide, an alternative receptor used by HIV to infect CD4 negative cells. These compounds consist of single- and double-chain amphiphiles containing one or two galactose residues. To favor their clustering into galactosyl-rich microdomains, their molecular structure contains also an amino group or several hydroxyls or anionic groups, such as carboxylate, sulfate, sulfonate, and phosphate. Among the 12 new galactosylated compounds reported, a specific anti-HIV activity, although moderate (IC(50) from 10 to 50 microM), was detected only for three of them, i.e., I-GalSer[CO2Na][C14], II-GalSer[C14][C7SO3Na], and II-GalSer[C2SO4Na][C14], which contain an anionic group. The marked increase of surface pressure which was observed upon addition of gp120 into the aqueous subphase underneath the monolayers containing these galactolipids indicated gp120 insertion into the monolayers, suggesting that binding of these three derivatives to HIV-1 gp120 may be responsible for their anti-HIV activity.

Abstract
Reactions that are relevant to the cleavage, by hydrazinolysis, of O-linked oligosaccharides from glycoproteins were studied using dehydroalanine derivatives as models of the intermediates formed from O-glycosylated serine residues. Conjugate addition of hydrazine followed by cyclisation to form pyrazolidinones, if occurring during glycoprotein hydrazinolysis, could reduce the yield of released oligosaccharide. However, N-acetyldehydroalanine amide derivatives, which modelled the dehydroalanine derivatives believed to be intermediates in the hydrazinolysis of glycoproteins containing O-linked oligosaccharides, underwent conjugate addition but no cyclisation.

Abstract
A facile strategy for the stereoselective synthesis of suitably protected O-glycosylated amino acid building blocks, namely, Nalpha-Fmoc-Ser-[Ac4-beta-D-Gal-(1-3)-Ac2-alpha or beta-D-GalN3]-OPfp and Nalpha-Fmoc-Thr-[Ac4-beta-D-Gal-(1-3)-Ac2-alpha or beta-D-GalN3]-OPfp is described. What is new and novel in this report is that Koenigs-Knorr type glycosylation of an aglycon serine/threonine derivative (i.e. Nalpha-Fmoc-Ser-OPfp or Nalpha-Fmoc-Thr-OPfp) with protected beta-D-Gal(1-3)-D-GalN3 synthon mediated by silver salts resulted in only alpha- and/or beta-isomers in excellent yields under two different reaction conditions. The subtle differences in stereoselectivity were demonstrated clearly when glycosylation was carried out using only AgClO4 at -40 degrees C which afforded a-isomer in a quantitative yield (alpha:beta = 5:1). On the other hand, the beta-isomer was formed exclusively when the reaction was performed in the presence of Ag2CO3/AgClO4 at room temperature. A complete assignment of 1H resonances to individual sugar ring protons and the characteristic anomeric alpha-1 H and beta-1 H in Ac4Galbeta(1-3)Ac2GalN3 alpha and/or beta linked to Ser/Thr building blocks was accomplished unequivocally by two-dimensional double-quantum filtered correlated spectroscopy and nuclear Overhauser enhancement and exchange spectroscopy NMR experiments. An unambiguous structural characterization and documentation of chemical shifts, including the coupling constants for all the protons of the aforementioned alpha- and beta-isomers of the O-glycosylated amino acid building blocks carrying protected beta-D-Gal(1-3)-D-GalN3, could serve as a template in elucidating the three-dimensional structure of glycoproteins. The synthetic utility of the building blocks and versatility of the strategy was exemplified in the construction of human salivary mucin (MUC7)-derived, O-linked glycopeptides with varied degrees of glycosylation by solid-phase Fmoc chemistry. Fmoc/tert-butyl-based protecting groups were used for the peptidic moieties in conjunction with acetyl sugar protection. The transformation of the 2-azido group into the acetamido derivative was carried out with thioacetic acid on the polymer-bound glycopeptides before the cleavage step. After cleaving the glycopeptide from the resin, the acetyl groups used for sugar OH-protection were removed with sodium methoxide in methanol. Finally, the glycopeptides were purified by reversed-phase high-performance liquid chromatography and their integrity was confirmed by proton NMR as well as by mass spectral analysis. Secondary structure analysis by circular dichroism of both the glycosylated and nonglycosylated peptides revealed that carbohydrates did not exert any profound structural effect on the peptide backbone conformation.

Abstract
Disaccharide-peptide conjugates were obtained in yields of 30-50% from o-nitrophenyl beta-D-galactopyranoside by employing beta-D-galactosidase from E. coli as catalyst. Two series of beta-D-galactosyldipeptides were examined as galactosyl acceptors. They both contain an L-serine residue beta-linked to the anomeric carbon of galactose. In the first series, serine is in the N-terminal position of the dipeptide; in the second series, serine is in the C-terminal position. The second amino acid is L-alanine or glycine. Some of our substrates gave a high yield of beta-(1-->3)-digalactosyldipeptide derivatives and all gave very little of the beta-(1-->6) regioisomer. The conditions and the limitations of the transgalactosylation reaction are discussed.

Abstract
A sensitive colorimetric assay for detecting mucins and glycoproteins rich in O-glycosidically linked saccharides is reported. The method combines the susceptibility of N-acetylgalactosamine terminating O-glycosidically linked saccharides to beta-elimination with the Morgan-Elson reaction for N-acetylhexosamines with free reducing ends. All mucin and mucin-type glycoproteins but none of the serum-type glycoproteins tested resulted in characteristic color production. All mucins tested gave linear responses in the range 5 to 200 micrograms and the assay was also adapted to the microscale involving the use of 96-well microtiter plates. The microassay in which the volumes of samples and reagents are scaled down 2.5-fold was particularly useful in monitoring of mucins, in the presence of other glycoconjugates, in large numbers of samples obtained during fractionation procedures. Cesium chloride, cesium bromide, potassium thiocyanate, and various detergents do not interfere with the colorimetric determination. Guanidine hydrochloride, cesium trifluoroacetate, and beta-mercaptoethanol decreased color by 30 to 45%; however, the interference was not serious to prevent the use of the method for detection of mucins in their presence. The use of the method for the specific detection of mucin during fractionation by gel filtration and density gradient centrifugation of cystic fibrosis sputum samples is demonstrated.

Abstract
The peeling reaction, the process by which oligosaccharides are degraded in alkali, was used as the basis for an assay to provide structural information about glycosidically linked oligosaccharides in glycoproteins. Glycoproteins were treated with 0.05 M NaOH at 50 degrees to induce release, and subsequent degradation ("peeling"), of glycosidically linked, but not of N-glycosydically linked, oligosaccharides. Among the degradation products generated from O-linked chains were three 3-deoxy sugar acids whose formation was correlated with certain structural features of the oligosaccharides. N-Acetylneuraminic acid was released from terminal positions in the oligosaccharides, and iso- and meta-saccharinic acids were derived from the degradation of 4-O- and 3-O-substituted hexoses, respectively. All of these sugar acids were detected colorimetrically by periodate oxidation and reaction of the product with 2-thiobarbituric acid. The ability of the method to generate 3-deoxy sugar acids was tested in 8 alkali-treated glycoproteins. 3-Deoxy sugar acids were detected only in those glycoproteins whose glycosidically linked carbohydrates contained N-acetylneuraminic acid, or 3-O- or 4-O-substituted hexoses, or both. As little as 0.12 microgram of 3-deoxy sugar acid produced from 5 micrograms of human chorionic gonadotropin was sufficient for detection. This method is novel in its ability to distinguish sialylation of glycosidically linked carbohydrates. Furthermore, it combines the specificity of beta-elimination with the sensitivity of the 2-thiobarbituric acid assay in targeting degradation products of the peeling reaction as candidates for an assay method.

Abstract
Structures of glycopeptides obtained by exhaustive Pronase digestion of high molecular weight (1.7 X 10(5)) salmon egg polysialoglycoprotein have been elucidated. Six principal glycopeptides isolated by gel chromatography and DEAE-Sephadex A-25 chromatography in the absence or presence of borate ion were analyzed for their carbohydrate and amino acid composition, as well as amino acid sequence, and found to be of two distinct types: glycotripeptides, Thr*-Ser*-Glu, and glycotetrapeptides, Thr*-Gly-Pro-Ser, where an asterisk indicates the amino acid residues to which either the Gal beta 1----3GalNAc or Fuc alpha 1----3GalNAc beta 1----3Gal beta 1----4Gal beta 1----3GalNAc chain is attached. Their final yield corresponds to 64% of the original desialylated glycoprotein. In view of the simple amino acid composition of salmon egg polysialoglycoprotein (molar ratio Asp2Thr2Ser3Glu1Pro1Gly1Ala3) and the result of alkaline beta-elimination indicating three carbohydrate units linked to two of two threonine and one of three serine residues, a unique primary structure comprising repetitive sequences of the above two types of glycopeptides, which are interspersed by short nonglycosylated peptides consisting of alanine and aspartic acid, has been proposed for the core protein. The molecular secondary ion mass spectra of underivatized glycopeptides were used to obtain their structural information. The anomeric configuration of the proximal sugar-peptide linkages was proven to be alpha by proton nuclear magnetic resonance spectroscopy. This is the first systematic reported study of O-glycosidically linked glycopeptides by these instrumental methods.

Abstract
During the deglycosylation reaction of fish egg polysialoglycoproteins under the conditions of 1 M NaBH4 in 0.1 M NaOH at 37 degrees C for 48 h, a marked loss of the glycine content has been encountered, besides the serine and threonine residues to which the carbohydrate units are linked. The chemical basis behind this phenomenon has been elucidated by amino acid analysis first of the major glycopeptides (carbohydrate-(O)Thr-Gly-Pro-Ser) derived from desialylated polysialoglycoproteins and subsequently six proline-containing peptides before and after treatment under similar conditions. It has thus been established that -Xaa-Pro- sequences are remarkably susceptible to reductive cleavage under such mild aqueous conditions. In view of the finding that the reductive cleavage of insulin B-chain, which contains a single proline residue adjacent and C-terminal to a threonine residue, led to about 80% loss of the threonine residue, deglycosylation with alkaline borohydride reagents warrants a special comment. The decreased amounts of serine or threonine residues cannot be related simply to the degree of glycosylation of these residues. The above results are therefore discussed in the relation to other work.

The O-glycosidically linked carbohydrate units of rat brain glycopeptides were released as reduced oligosaccharides with NaOH/NaBH4 treatment. Five oligosaccharides were isolated using gel filtration, ion-exchange chromatography and preparative thin-layer chromatography. Studies employing periodate oxidation, methylation analysis, chromium trixide oxidation and gas-liquid chromatography-mass spectrometry indicated the following structures: (I) alpha-galactosyl-(1 leads to 3)-N-acetylgalactosaminitol, (II) beta-galactosyl-(1 leads to 3)-N-acetylgalactosaminitol, (III) N-acetylneuraminyl-[beta-galactosyl-(1 leads to 3)-N-acetylgalactosaminitol], (IV) N-acetylneuraminyl-(2 leads to 3)-beta-galactosyl-(1 leads to 3)-N-acetylgalactosaminitol and (V) N-acetylneuraminyl-(2 leads to 3)-beta-galactosyl-(1 leads to 3)[N-acetylneuraminyl-(2 leads to 6)]-N-acetylgalactosaminitol.
