Chitooligosaccharide Synthesis Using an Ionic Tag

An environmentally improved synthesis of the N-differentiated chitotetrasaccharide CO-IV-(NH2), a key intermediate for the preparation of lipochitooligosaccharides and the TMG-chitotriomycin, is reported based on a chromatography-free ionic-liquid tagging approach. The method involves the glycosylation of ionic-liquid-tagged acceptors with thioglucosamine donors leading to the stereoselective formation of beta-(1?4)-linked glucosamine-containing oligomers.

Chemical Modification of the N Termini of Unprotected Peptides for Semisynthesis of Modified Proteins by Utilizing a Hydrophilic Protecting Group

A simple and efficient strategy for the selective modification of the peptide N terminus with an unnatural amino acid is described. A peptide having a SUMO-HisTag-TEV sequence (SUMO: small ubiquitin-related modifier, TEV: tobacco etch virus) preceding the N terminus of the target peptide was designed. Recombinant expression in E. coli and subsequent SUMO protease cleavage yielded the HisTag-TEV-target peptide. Partial protection of the lysine side chains of this peptide with d-glucopyranosyloxycarbonyl and removal of the HisTag-TEV sequence by TEV protease yielded the partially protected peptide with a free N-terminal amine. Coupling of selenocysteine selectively at the N terminus and subsequent acidic deprotection of the carbohydrate protecting groups yielded a modified peptide that can be used for native chemical ligation (NCL). As a proof of concept, the modification of a longer recombinant peptide with selenocysteinylserine (GalNAc) at the N terminus was demonstrated.

Characterization and antifungal study of genuine oxovanadium(IV) mixed-ligand complexes with schiff bases

New oxovanadium(IV) complexes [VO(L)(A)] (KHL = potassium salt of o-hydroxy-acetophenoneglycine, A1 = 2,2?-bipyridylamine, A 2 = bis(benzylidene)ethylenediamine, A3 = thiophene-o-carboxaldeneaniline, A4 = thiophene-o-carboxaldene-p- toluidine, A5 = bis(benzylidene)-1,8-diaminonaphthalene, A 6 = bis(acetophenone)ethylenediamine) have been isolated and characterized by elemental analyses, infrared spectra, electronic spectra, magnetic measurement and thermogravimetric analyses. An octahedral geometry has been assigned to all the VO(IV) complexes. The antifungal activity of Schiff bases, oxovanadium(IV) complexes, vanadyl sulphate, control (DMSO) and fungicides (bavistin and emcarb) have been evaluated against A. niger, F. oxysporum and A. flavus, which show clear enhancement in the antifungal activity upon complexation with Schiff bases but moderate activity as compared to the standard fungicides bavistin and emcarb.

Carbohydrate coatings via aryldiazonium chemistry for surface biomimicry

Carbohydrates are extremely important biomolecules and their immobilization onto solid surfaces is of interest for the development of new biomimetic materials and of new methods for understanding processes in glycobiology. We have developed an efficient surface modification methodology for the functionalization of a range of materials with biologically active carbohydrates based on aryldiazonium chemistry. We describe the synthesis and characterization of carbohydrate reagents, which were subsequently employed for the one-step, solution-based modification of carbon, metals, and alloys with monosaccharides. We used a combination of spectroscopic and nanogravimetric methods to characterize the structure of the carbohydrate layers; we report an average surface coverage of 7.8 ¡Á 10-10 mol cm-2 under our experimental conditions. Concanavalin A, a mannose-binding lectin, and Peanut Agglutinin, a galactose-binding lectin, were found to bind from solution to their respective monosaccharide binding partners immobilized at the surface. This result suggests that the spontaneous chemisorption of aryldiazonium monosaccharide precursors leads to the formation of monosaccharide layers that retain the biological recognition specificity of the parent carbohydrate molecule. Finally, we carried out measurements using fluorescently labeled Bovine Serum Albumin (BSA) and found that these carbohydrate coatings reduce unspecific adsorption of this protein at carbon surfaces. These results suggest that aryldiazonium-derived carbohydrate coatings may offer a promising strategy for preventing undesirable protein accumulation onto surfaces.

Optimisation of ITK inhibitors through successive iterative design cycles

Based on a hit cluster of compounds inhibiting interleukin-2 inducible T-cell kinase (ITK) in the submicromolar range a series of ITK inhibitor libraries were synthesized. Through iterative design cycles including kinase crystal structure information, indolylindazole libraries were identified which showed low nanomolar activity in enzymatic and cellular assays. The potential of these novel lead series was confirmed through in vivo tests in an anti-CD3-IL2 mouse model. The intravenous administration of highly potent ITK inhibitor 11o resulted in dose-dependent, efficient suppression of IL-2.

Isolation of an N-acetyl-d-glucosamine specific lectin from the rhizomes of Arundo donax with antiproliferative activity

A lectin with antiproliferative activity towards human cancer cell lines and mitogenic towards human peripheral blood mononuclear cells was purified from the rhizomes of Arundo donax (Linn.) by affinity chromatography on N-acetyl-d-glucosamine linked to epoxy-activated sepharose-6B. The pure preparation apparently yielded a single band of approximately 15 kDa on SDS-PAGE, pH 8.3, under both reducing and non-reducing conditions. The molecular mass of native lectin was 32 kDa as determined by gel filtration chromatography. This showed the lectin to be a dimer, with subunits not held together by disulphide linkages. The A. donax lectin (ADL) agglutinated rabbit erythrocytes and the agglutination was inhibited by N-acetyl-d-glucosamine and its di- and trimer. The lectin was thermostable upto 55C and showed optimum activity in the range of pH 7.0-9.0 and comprised of 2.1% carbohydrate content.
