TMSCl as a mild and effective source of acidic catalysis in Fischer glycosidation and use of propargyl glycoside for anomeric protection

Practical Fischer glycosidation was effected at room temperature or 60C by using 5 to 10 equiv. of TMSCl. The anomeric propargyl group formed by this method was found to be a versatile new protecting group, being stable in neat TFA but readily cleaved by treatment with Co2(CO)8 and TFA in CH2Cl2 via the formation of an alkyne-Co complex.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 14215-68-0, you can also check out more blogs about14215-68-0

Isolation of novel prototype galectins from the marine ball sponge Cinachyrella sp. guided by their modulatory activity on mammalian glutamate-gated ion channels

Here we report the bioactivity-guided isolation of novel galectins from the marine sponge Cinachyrella sp., collected from Iriomote Island, Japan. The lectin proteins, which we refer to as the Cinachyrella galectins (CchGs), were identified as the active principles in an aqueous sponge extract that modulated the function of mammalian ionotropic glutamate receptors. Aggregation of rabbit erythrocytes by CchGs was competed most effectively by galactosides but not mannose, a profile characteristic of members of the galectin family of oligosaccharide-binding proteins. The lectin activity was remarkably stable, with only a modest loss in hemagglutination after exposure of the protein to 100C for 1 h, and showed little sensitivity to calcium concentration. CchG-1 and -2 appeared as 16 and 18 kDa in sodium dodecyl sulfate-polyacrylamide gel electrophoresis, respectively, whereas matrix-assisted laser desorption ionization-time-of-flight-mass spectrometry indicated broad ion clusters centered at 16,216 and 16,423, respectively. The amino acid sequences of the CchGs were deduced using a combination of Edman degradation and cDNA cloning and revealed that the proteins were distant orthologs of animal prototype galectins and that multiple isolectins comprised the CchGs. One of the isolectins was expressed as a recombinant protein and exhibited physico-chemical and biological properties comparable with those of the natural lectins. The biochemical properties of the CchGs as well as their unexpected activity on mammalian excitatory amino acid receptors suggest that further analysis of these new members of the galectin family will yield further glycobiological and neurophysiological insights.

Synthesis and Study of Molecular Assemblies Formed by 4,6-O-(2-Phenylethylidene)-Functionalized d -Glucosamine Derivatives

Low-molecular-weight gelators are interesting small molecules with potential applications as advanced materials. Carbohydrate-based small molecular gelators are especially useful because they are derived from renewable resources and are more likely to be biocompatible and biodegradable. Various 4,6-benzylidene acetal protected alpha-methyl 2-d-glucosamine derivatives have been found to be effective low-molecular-weight gelators. To understand the influence of the 4,6-benzylidene acetal functional group toward molecular self-assembly and to obtain effective molecular gelators, we synthesized and analyzed a new series of d-glucosamine derivatives in which the phenyl group of the acetal is replaced by a benzyl group. The homologation of the acetal protection from aromatic to aliphatic functional groups allows us to probe the effect of increasing structural flexibility on molecular self-assembly and gelation. In this study, nine representative amides and nine urea analogs were synthesized, and their gelation properties were analyzed in a series of organic solvents and aqueous solutions. The resulting amide and urea derivatives are versatile organogelators forming gels in toluene, ethanol, isopropanol, ethylene glycol, and aqueous mixtures of organic solvents. More interestingly, the amide analogs are also effective gelators for pump oil and engine oil. NMR spectroscopy at variable temperatures was used to analyze the molecular assemblies and intermolecular forces. The selected gelators with several drug and dye molecules in DMSO and water were studied for their effectiveness of encapsulation and release of these agents.

Aniphiphilic and mesogenic carbohydrates. 10. Change of the type of the mesophase by variation of the acyl chain of amphiphilic tetradecyl (N-acylamino)-2-deoxy-1-thio-beta-D-glucopyranosides

The homologous amphiphilic tetradecyl-2-(N-alkanoylamino)-2-deoxy-1-thio-beta-D-glucopyranosides 5a-f were synthesized from the 2-(N-alkanoylamino)-2-deoxy-D-glucopyranoses 1a-f via the glucosyl chlorides 2a-f, the glucosyl isothiuronium chlorides 3a-f, and the acetylated thioglucosides 4a-f. On heating the amphiphiles 5a-f form different types of liquid crystalline phases in dependence of the length of the acyl chain, i.e. 5a and 5b form smectic phases, 5d-f form columnar mesophases. Polarisation microscopy, DSC-measurements and contact preparations were used to characterise the liquid crystalline phases.
