Abstract
The so-called "sialo-chemical-biology" has become an attractive research area, as an increasing number of natural products containing a sialic acid moiety have been shown to play important roles in biological, pathological, and immunological processes. The intramolecular lactones of sialic acids are a subclass from this crucial family that could have central functions in the discrimination of physiological and pathological conditions. In this review, we report an in-depth analysis of the synthetic achievements in the preparation of the intramolecular lactones of sialic acids (1,4-, 1,7- and γ-lactones), in their free and/or protected form. In particular, recent advances in the synthesis of the 1,7-lactones have allowed the preparation of key sialic acid derivatives. These compounds could be used as authentic reference standards for their correct determination in biological samples, thus overcoming some of the limitations of the previous analytical procedures.

Abstract
Elevated titers of serum antibodies against GM1 ganglioside are associated with a variety of autoimmune neuropathies. Much evidence indicates these autoantibodies play a primary role in the disease processes, but the mechanism for their appearance is unclear. We studied the fine specificity of anti-GM1 antibodies of the IgG isotype present in sera from patients with Guillain-Barré syndrome (GBS), using thin-layer chromatogram-immunostaining of GM1, asialo-GM1 (GA1), GD1b and GM1-derivatives with small modifications on the oligosaccharide moiety. We were able to distinguish populations of antibodies with different fine specificity. Remarkably, individual patients presented only one or two of them, and different patients had different populations. This restriction in the variability of antibody populations suggests that the appearance of the anti-GM1 antibodies is a random process involving restricted populations of lymphocytes. With the origin of disease-associated anti-GM1 antibodies as a context, this finding could provide explanation for the “host susceptibility factor” observed in GBS following enteritis with GM1 oligosaccharide-carrying strains of Campylobacter jejuni.

Abstract
Four unidentified acidic glycolipids (X3-X6) were isolated from the kidney of the Pacific salmon on an anion exchange column and by high performance liquid chromatography using a silica bead (Iatrobeads) column. Based on methylation analysis, chemical and enzymatic degradation, proton nuclear magnetic resonance spectroscopy and mass spectrometry, the glycon structure of X5 and X6 was identified as a unique disialosyl fucosyl-N-acetylgalactosaminyl ganglio-N-tetraose:Fucalpha3GalNAcbeta3Galbeta3GalNAcbeta4[NeuAcalpha8NeuAcalpha3] Galbeta4Glcbeta1Cer. NMR showed that X3 and X4 were analogues of X5 and X6 and contained O-acetyl groups on C4 of the outer N-acetylneuraminic acid, first disialosyl gangliosides containing 4-O-acetyl-N-acetylneuraminic acid. The ceramides of X3 and X5 contained predominantly C24: 1, and X4 and X6 contained saturated fatty acids (C14: 0, C16: 0 and C18: 0), whereas the long chain base was exclusively sphingenine. The concentrations of X3 and X4 were 0.13 and 0.16 nmol/g of kidney respectively and those of X5 and X6, were 0.07 nmol/g each.

Abstract
The lactonisation of alpha-Neup5Ac-(2-->8)-alpha-Neup5Ac-(2-->3)-beta-D-Galp-(1-->4)-D-Glc (disialyl lactose) was investigated. (1)H and (13)C NMR chemical shifts of disialyl lactose and alpha-Neup5Ac-(2-->8, 1-->9)-alpha-Neup5Ac-(2-->3, 1-->2)-beta-D-Galp-(1-->4)-D-Glc (disialyl lactose-dilactone) were assigned based on 1D and 2D NMR results, including edited HSQC, HSQC-TOSCY and HMBC. The time course of lactonisation was followed by thin layer chromatography (TLC) and high-performance liquid chromatography (HPLC) with electrospray ionisation (ESI) mass spectrometry (MS) detection. The rate of lactonisation between alpha-(8)Neu5Ac and alpha-(3)Neu5Ac residues (lactonisation at the alpha-(2-->8) linkage) was faster than that of lactonisation between alpha-(3)Neu5Ac and Gal residues (lactonisation at the alpha-(2-->3) linkage). The mass spectra of disialyl lactose, its lactones, alpha-Neup5Ac-(2-->8)-alpha-Neup5Ac (alpha-(2-->8) disialic acid) and alpha-Neup5Ac-(2-->3)-beta-D-Galp-(1-->4)-D-Glc-lactone (3'-sialyllactose-lactone) showed that the alpha-(2-->8) linkage between Neu5Ac residues is difficult to cleave in the ESI-MS, compared with the alpha-(2-->3) linkage between Neu5Ac and Gal residues.

Abstract
A simple procedure is described for preparing GM3 ganglioside, from a few milligrams to grams, from GM1-lactone (Sonnino et al., (1985) Glycoconjugate J 2: 343-54) [1]. The synthesis was carried out under the following optimal conditions: 30 mM GM1-lactone in 0.25 M H2SO4 in DMSO, 30 min, 70 degrees C, nitrogen atmosphere, strong stirring. The yield of GM3 was 55%. The procedure applied to milligram amounts of GD1b-dilactone gave GD3 ganglioside.

Abstract
Ganglioside lactones in Minke whale brain were analysed. In order to exclude the possibility of the artificial lactonization of gangliosides during the analytical procedures, lactone species were separated from their parent gangliosides at an early stage by DEAE-Sephadex A-25 column chromatography using a stepwise elution. Applying the improved method, GM41 lactones were found in grey and white matters of cerebrum and cerebellum, while GD3 monolactone was found only in cerebellar gray matter. The concentration of each ganglioside lactone was one thousandth of the parent ganglioside.

Abstract
Glycosphingolipids are uniquely distinguished amongst the glycoconjugates by the apparently systematic structuring of their ceramide-linked carbohydrate moieties. These often highly complex oligosaccharides provide a structural repertoire that may vary considerably according to cell types and animal species. However, as a possible reflection of their specific functional role in the central nervous system, the brain glycosphingolipids of all vertebrates follow the same principles of carbohydrate structuring with only minor variations: the anabolically early addition of sialic acid to lactosylceramide (Gal beta 4Glc beta Cer-->NeuAc alpha 3Gal beta 4Glc beta Cer) in central nervous tissue results in the preferential formation of 'gangliosides', i.e., sialic acid-containing glycosphingolipids. Higher gangliosides result from extensions of sialo-lactosylceramide by addition of nucleotide-activated monosaccharides. In consequence, gangliosides of the vertebrate central nervous system consist of ceramide-linked sialo-oligosaccharides of varying chain length with a ganglio-series core carbohydrate, i.e., GalNAc beta 4Gal beta 3GalNAc beta 4Gal beta 4Glc beta < 0. Substitution by mono-, bis-, or tris-sialo-groups may variably be at the galactoside- and N-acetylgalactosaminide residues in 3- and 6-positions of the ganglio-series oligosaccharides, respectively. Ganglioside, which is derived by sialylation of galactosylceramide, NeuAc alpha 3Gal beta Cer, is a characteristic constituent of glial cells. In nerve tissue, gangliosides of the lacto-(Gal beta(3GlcNAc beta 3Gal beta)n4Glc beta <) and the neolacto-series (Gal beta(4GlcNAc beta 3Gal beta)n4Glc <) are more characteristic of vertebrate peripheral nerves and neuroectoderm-derived tumours. Recent studies using monoclonal antibodies have revealed that various single ganglioside components are specifically distributed in nervous tissues. This finding adds a new dimension to the earlier notion that gangliosides are involved in membrane related phenomena including cell to cell interactions, as well as, the modulation of signalling mechanisms.

Abstract
Circular dichroism spectrometry was applied to gangliosides and their lactones and revealed that the lactones have a characteristic strong negative Cotton effect around 235 nm. Four monolactones and two dilactones, which were formed from GM4, GD3, and GD1b, gave molar ellipticities at the wavelength in magnitude of 10(4), while their parent gangliosides, along with other gangliosides such as GM3, GM1, GD1a, GT1b, and GQ1b, showed no distinct feature. Two ganglioside esters, GM4-methyl ester and O-Ac-GT1b did not show the Cotton effect. The molar ellipticities had an additivity with respect to the number of lactone rings. The Cotton effect was attributed to the carbonyl group on the lactone ring.

Abstract
A comparative study on the conformational features of the oligosaccharide moiety of GD1b and GD1b lactone gangliosides, in dimethylsulphoxide, has been carried out by nuclear Overhauser effect investigation; the experimental interresidue contacts have been used for restrained molecular mechanics and dynamics calculations. For GD1b, the tetrasaccharide beta-GalNAc-(1----4)-[alpha-Neu5Ac-(2 ----8)-alpha-Neu5Ac-(2----3)]-beta-Gal has a circular arrangement leaving a highly hydrophobic region with seven hydrogens pointing towards the center. At one side of this region the three electron rich groups GalNAc--NH, external Neu5Ac--OH4 and internal Neu5Ac--COO- are grouped together; at the other side five polar groups (four hydroxy groups and the external Neu5Ac carboxylate) define a large annular hydrophilic region. The external Neu5Ac is close to the external Gal residue, and the external Neu5Ac--COO- is within van der Waals contact with the inner Neu5Ac-OH9 group. The beta-Gal-(1----3)-beta-GalNAc glycosidic linkage shows a high degree of freedom. For GD1b-L, the trisaccharide beta-GalNAc-(1----4)-[alpha-Neu5Ac-(2----3)]-beta-Gal is disposed to forming rigid partially circular arrangement showing strong interresidue contacts between the inner Neu5Ac-H8 and both GalNAc-H1 and GalNAc-H5. The conformation of the lactone ring is the boat 9(A),2(B)B. The lactonization of the disialosyl residue induces a strong variation of the preexisting torsional glycosidic angles phi and psi, leaving the external Neu5Ac far from the external Gal. In both GD1b and GD1b lactone gangliosides, the conformation of the sialic acid side chain is the same as that of the free sialic acid in which the H7 is trans to H8 and gauche to H6, thus indicating that the presence of glycosidic and/or ester linkages does not affect the conformational properties of sialic acid. Both GD1b and GD1b lactone containing sialic acid carboxylate anion(s) or undissociated carboxyl group(s) show the same three dimensional structure, indicating that the presence of charges does not affect the intrinsic conformational features of gangliosides.
