SUBSTANCE THAT INHIBITS THE ADHERENCE OF BACTERIA AFFECTING THE RESPIRATORY TRACT OF MAMMALS

A substance aimed at inhibiting the adherence of bacteria affecting the respiratory tract of mammals was developed. This substance is composed of a mixture of carbohydrates that bind to the bacterial adhesins and/or cellular receptors of the host and block the bacteria-host interaction, preventing bacterial adherence to the epithelium and the development of infection.

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.HPLC of Formula: C8H15NO6, you can also check out more blogs about14215-68-0

Structure and gene cluster of the O-antigen of Escherichia coli O30

The acidic O-polysaccharide (O-antigen) of Escherichia coli O30 was isolated from the lipopolysaccharide and studied by sugar analysis and NMR spectroscopy. The following structure of the branched tetrasaccharide repeating unit was established, which is unique among known structures of bacterial polysaccharides: beta-D-GlcpNAc 1?2 ?4)-beta-D-GlcpA-(1?4)- beta-D-GlcpA-(1?3)- alpha-D-GlcpNAc-(1? The O-antigen gene cluster of E. coli O30 was sequenced. The gene functions were tentatively assigned by comparison with sequences in the available databases and found to be in full agreement with the O-polysaccharide structure.

The versatility of N-alkyl-methoxyamine bi-functional linkers for the preparation of glycoconjugates

The application of N-glycosyl-N-alkyl-methoxyamine bi-functional linkers for the synthesis of a variety of glycoconjugates is described. The linker contains a specific functional group, such as an amine, azide, thiol, or carboxylic acid, which can be used for conjugation methodologies that include amide ligation, sulfonylation, copper-mediated Huisgen cycloaddition or thiol-maleimide coupling. In this way, glycoconjugates equipped with biotin, a fluorescent reporter, or a protein were efficiently synthesised, thus demonstrating the versatility of this type of oxyamine linker for the construction of glycoconjugate probes.

Mimicry of tandem repeat peptides against cell surface carbohydrates

Our approach to multivalent peptide construction relies on tentacle peptides, also known as a multiple antigenic peptides, which contain two and four repeats of a selected peptide. In this communication, we report the results of preliminary studies aimed at (1) the selection of short peptides against the carbohydrate, sLeX, (2) the synthesis of tentacle dimers and tetramers of the selected peptides, and (3) the determination of affinities and specificities of the peptides to several related carbohydrates by using the surface plasmon resonance (SPR) and the equilibrium dialysis techniques. Binding affinity studies, as well as assays of in vitro binding of the peptides to a sLeX-specific cell line, have shown that the tetrameric peptides bind to the cell surface sugars. Copyright

Antineoplastic agents. 443. Synthesis of the cancer cell growth inhibitor hydroxyphenstatin and its sodium diphosphate prodrug

A structure – activity relationship (SAR) study of the South African willow tree (Combretum caffrum) antineoplastic constituent combretastatin A-4 (3b) led to the discovery of a potent cancer cell growth inhibitor designated phenstatin (5a). This benzophenone derivative of combretastatin A-4 showed remarkable antineoplastic activity, and the benzophenone derivative of combretastatin A-1 was therefore synthesized. The benzophenone, designated hydroxyphenstatin (6a), was synthesized by coupling of a protected bromobenzene and a benzaldehyde to give the benzhydrol with subsequent oxidation to the ketone. Hydroxyphenstatin was converted to the sodium phosphate prodrug (6e) by a dibenzyl phosphite phosphorylation and subsequent benzyl cleavage (6a ? 6d ? 6e). While hydroxyphenstatin (6a) was a potent inhibitor of tubulin polymerization with activity comparable to that of combretastatin A-1 (3a), the phosphorylated derivative (6e) was inactive.

Chitosan: Emergence as potent candidate for green adhesive market

Chitosan has gained significant attention during last decades as a potent natural adhesive. Its lower concentrations (<10% w/v) offer competitive strength as synthetic adhesives which would reduce economic constrains of adhesive production. There is increasing commercial interest on chitosan as it possesses biodegradability, biocompatibility, non-toxicity and anti-microbial properties which are of high interest for industries and consumers. Moreover, it has reactive amino side groups, which offer possibilities of chemical modification, increased ionic interactions and graft-reactions etc. Degree of deacetylation (DD) and molecular weight (Mw) is important in bonding mechanism. Most of the synthetic adhesives are comprised of petrochemicals that leave toxic residues such as formaldehyde and volatile organic compounds (VOCs), which are injurious to health and environment. Therefore, development of cost-effective, environmental and health-friendly green adhesives, based on renewable resources is main interest of adhesive industries these days. Rising oil prices are another driving force in research for development of bioadhesives as substitute of synthetic adhesives. This review is focused on current developments of chitosan adhesives for structural and general bonding applications during last decades as well as its current market potential worldwide.
