Synthesis of a potential 10E4 tetrasaccharide antigen involved in scrapie pathogenesis

To test the hypothesis that tetrasaccharide 3 is involved in scrapie pathogenesis, tetrasaccharide derivative 32 functionalized with an amine linker at the reducing end was synthesized. A (2 + 2) glycosylation approach was chosen to furnish the target compound in fully protected form. To investigate its biological role, tetrasaccharide 32 was further functionalized to the corresponding thiol 33 using Traut’s reagent. During the course of the synthesis, the N,N-diacetyl protecting group proved surprisingly labile to radical and acidic conditions.

Total Synthesis of Tri-, Hexa- and Heptasaccharidic Substructures of the O-Polysaccharide of Providencia rustigianii O34

A general and efficient strategy for synthesis of tri-, hexa- and heptasaccharidic substructures of the lipopolysaccharide of Providencia rustigianii O34 is described. For the heptasaccharide seven different building blocks were employed. Special features of the structures are an alpha-linked galactosamine and the two embedded alpha-fucose units, which are either branched at positions-3 and -4 or further linked at their 2-position. Convergent strategies focused on [4+3], [3+4], and [4+2+1] couplings. Whereas the [4+3] and [3+4] coupling strategies failed the [4+2+1] strategy was successful. As monosaccharidic building blocks trichloroacetimidates and phosphates were employed. Global deprotection of the fully protected structures was achieved by Birch reaction.

Supramolecular self-assembly of nucleotide-metal coordination complexes: From simple molecules to nanomaterials

Nucleotides are essential components of DNA and RNA, and their functions depend mainly on the participation of metal ions. Thus, research into nucleotide-metal coordination complexes, including the affinities of different coordination donors for metal ions, molecular and crystal structures, supramolecular assembly, and functional nanoparticles, will contribute to the interdisciplinary field of chemistry, biology, and materials. Numerous achievements have been reported in this area but few comprehensive reviews have considered nucleotide-metal complexes from the viewpoints of crystallography and supramolecular chemistry, or aspects of their chirality and chirality delivery. In this review, we describe the coordination ability of nucleotide ligands, the structures and properties of nucleotide-metal coordination complexes, and supramolecular assemblies. We review mononuclear complexes, multinuclear complexes, 1D and 2D coordination polymers, and 3D supramolecular assemblies in terms of their structures, mainly based on their X-ray single crystal diffraction data. In particular, we highlight the chirality of nucleotide-metal complex, including their molecular chirality, supramolecular helical chirality, and extended axial chirality. Furthermore, we summarize the functional properties of nucleotide-metal nanomaterials, such as their luminescence, magnetism, and adaptive inclusion properties. We discuss the future challenges and opportunities of research into nucleotide-metal complex.

Transformation of lactitol crystals and dehydration with grinding

The transformation of monohydrate, dihydrate, two polymorphic forms (A and B) of anhydrate and the amorphous form of lactitol [(+)-4-O-beta-D- galactopyranosyl-D-glucitol] were investigated by infrared spectrum, differential scanning calorimetry and X-ray powder diffraction. Monohydrate and dihydrate were transformed to anhydrate A and anhydrate B after storage at 80C for 24 h under reduced pressure, respectively, but both hydrates changed to anhydrate A after being at 105C for 3 d. Five solid forms were stored under the relative humidity (RH) range from 12 to 93% at 25C for 14d. Monohydrate was transformed into dihydrate at RH more than 90%, but no change was observed in the range from 12 to 84% RH. Dihydrate did not show any transformation in the experimental RH range, though weight increase and decrease were observed at 12 and 93% RH, respectively. Both anhydrate A and B, however, were changed to monohydrate but this transformation occurred under different RH conditions (anhydrate A: 22% RH, anhydrate B: 75% RH). The amorphous form was transformed into monohydrate and dihydrate in the RH range from 53 to 84% and at 90% RH, respectively. The effect of grinding on the thermal behavior of the two hydrates was investigated, dehydration temperatures of monohydrate, which was determined by controlled rate thermogravimetry, was about 15C lower than the intact monohydrate. However, no change in dehydration temperature was observed for dihydrate. These results suggest that the influence of grinding on thermal behavior was different for the two hydrates.

Structurally diverse disaccharide analogs of antifreeze glycoproteins and their ability to inhibit ice recrystallization

The beta-D-galactosyl-(1,3)-alpha-N-acetyl-D-galactosamine disaccharide is present in antifreeze glycoproteins (AFGPs). Analogs of this disaccharide including the beta-linked (1,3)-, (1,4)-, and (1,6)-galactosyl-N-acetyl galactosamine and the beta-(1,3)-galactosyl-galactoside were synthesized and evaluated for ice recrystallization inhibition (IRI) activity. The results from this study demonstrate that the b-linked-(1,4) disaccharide exhibits more potent IRI activity than the native b-linked-(1,3) disaccharide. The C2 N-acetyl group of the disaccharide does not affect IRI activity but in monosaccharides, the presence of the C2 N-acetyl group decreases IRI activity. The current study will facilitate the design of potent small-molecule ice recrystallization inhibitors.

A novel trinuclear-based polymeric Cu(II) complex with uniquely bridged HxPO4(3-x)- anions, [Cu3(di-2-pyridylamine) 3(mu3,eta3-HPO4) (mu3,eta4-PO4)(H2O)](PF 6)(H2O)3}n 1 has been synthesized and characterised. Each Cu(II) ion in the polynuclear unit is linked by hydrogenphosphato and phosphato bridges showing mu3,eta3-HPO42-and an unprecedented mu3,eta4-PO43- coordination mode. Two different coordination geometries around the Cu(II) ions are found in the polynuclear unit: an intermediate geometry between square pyramidal and trigonal bipyramidal and a tetrahedrally distorted square-based pyramidal geometry. The Cu ? Cu distances vary from 4.408(3) to 5.942(3) A?. From variable magnetic susceptibility measurements (5-250 K) a weak antiferromagetic interactions between the Cu(II) ions in the trinuclear unit with an exchange parameter of J = -4.98 cm-1 and a very weak antiferromagnetic interaction between neighbouring units with zJ? = -1.49 cm-1 are observed.

Iron(III) complexes: Preparation, characterization, antibacterial activity and DNA-binding

Iron(III) have been combined to well known quinolones (ciprofloxacin) and some Schiff bases with the help of coordination approach. Characterization of these compounds have been done using elemental analysis, magnetic measurements, thermogravimetric analysis, IR, UV-VIS, 1H NMR and 13C NMR spectral investigation. Analytical studies suggest that the iron(III)-quinolone complexes assume a six-coordinated dimeric distorted octahedral geometry. All the compounds show a good antibacterial activity against broad range of bacteria like Bacillus cereus, Staphylococcus aureus, Escherichia coli, Bacillus subtilis, Salmonella typhi and Serratia marcescens, whereas no significant inhibition towards growth of fungal strains like Aspergillus Niger, Aspergillus flavus and Lasiodiplodia theobromae. Analyses of all these compounds show effective sperm herring DNA inhibition.
