Design of multifunctional polysaccharides for biomedical applications: A critical review

Background: Natural polysaccharides such as alginates, pectins, and chitins, possess a wide versatility in addition to the variability of the typical structural features of polysaccharides, as they include amino-, amido-, carboxylic acid, and esters groups. Objective: These functional groups can be exploited to graft specific moieties and macromolecules, thus tailoring the specific characteristics when envisioning improved functionality, such as targeted-drug delivery, antimicrobial, and thermo-or pH-responsiveness. Ad hoc covalent modifications of the polysaccharidic backbone can promote the loading and interactions with a wide variety of both hydrophilic and hydrophobic substances, as well as enhanced cell adhesion able to promote regeneration events. Additionally, enzymatic modifications have been conducted to have precise control of both functional groups and biodegradation. Conclusion: This review intends to give an overview over chemical and enzymatic reactions to modify the backbone of polysaccharides aiming to exploit organic chemistry tools applied to meet the diverse needs of biomedicine.

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.Product Details of 14215-68-0, you can also check out more blogs about14215-68-0

Enhanced enzymatic hydrolysis of langostino shell chitin with mixtures of enzymes from bacterial and fungal sources

A combination of enzyme preparations from Trichoderma atroviride and Serratia marcescens was able to completely degrade high concentrations (100 g/L) of chitin from langostino crab shells to N-acetylglucosamine (78%), glucosamine (2%), and chitobiose (10%). The result was achieved at 32C in 12 days with no pre-treatment (size reduction or swelling) of the substrate and without removal of the inhibitory end-products from the mixture. Enzymatic degradation of three forms of chitin by Serratia/Trichoderma and Streptomyces/Trichoderma blends was carried out according to a simplex-lattice mixture design. Fitted polynomial models indicated that there was synergy between prokaryotic and fungal enzymes for both hydrolysis of crab chitin and reduction of turbidity of colloidal chitin (primarily endo-type activity). Prokaryotic/fungal enzymes were not synergistic in degrading chitosan. Enzymes from prokaryotic sources had much lower activity against chitosan than enzymes from T. atroviride.

Enzymatic synthesis of vancomycin derivatives using galactosyltransferase and sialyltransferase

Analogs of vancomycin and pseudo-vancomycin with new sugar attachments in mono- and di-saccharide form have been enzymatically synthesized by glycosylation with overexpressed glycosyltransferases, beta1,4- galactosyltransferase and alpha2,3-sialyl transferases. All four analogs, including galactose-containing derivatives (6 and 8) and galactose- and sialic acid-containing derivatives (7 and 9) were prepared and characterized by HPLC, LC-MS, NMR and MIC test.

Versatile acetylation of carbohydrate substrates with bench-top sulfonic acids and application to one-pot syntheses of peracetylated thioglycosides

Inexpensive and readily available sulfonic acids, p-toluenesulfonic acid, and sulfuric acid are versatile and efficient catalysts for the peracetylation of a broad spectrum of carbohydrate substrates in good yield and in a practical time frame. Three appealing features in sulfonic acid-catalyzed acetylation of free sugars were explored including (1) suppression of furanosyl acetate formation for d-galactose and l-fucose; (2) high yielding chemoselective acetylation of sialic acid under appropriate conditions; and (3) peracetylation of amino sugars with different amino protecting functions. Simple one-pot two step acetylation-thioglycosidation methods for the expeditious synthesis of p-tolyl per-O-acetyl thioglycosides were also delineated.

Detection of metabolite changes in C6 glioma cells cultured with antimitotic oleyl glycoside by1H MAS NMR

The synthetic glycoside, oleyl N-acetyl-alpha-D-glucosaminide (1), was previously shown to exhibit antimitotic activity on rat (C6) and human (U-373) glioma lines. To obtain information about its mechanism of action, metabolite changes in C6 glioma cells were analyzed after treatment with 1 using high-resolution magic angle spinning 1H NMR. Compound 1 caused either a decrease or an increase in the intensity of the signal assigned to coenzyme A (CoA) metabolites depending on the concentration used. The data obtained from the 1H NMR spectra of cells cultured with 1, combined with those obtained after treatment with oleic acid (an inhibitor of acetyl-CoA carboxylase) and phenyl butyrate (a known antineoplastic agent), suggest that 1 may be altering the metabolism of fatty acids and induce apoptosis of C6 glioma cells. These results point to NMR spectroscopy as an efficient technique for monitoring the response of the cells to therapeutic agents.

Tight binding ligand approach to oligosaccharide-grafted protein

A novel type of artificial glycoprotein was developed, by using dihydrofolate reductase (DHFR) and methotrexate (MTX) as a protein-ligand pair. Various oligosaccharides linked to MTX were shown to bind tightly with DHFR and afforded oligosaccharide-grafted protein, which could be isolated easily by lectin beads.

Stabilization of beta-Gal-3 ATCC 31382 on agarose gels: Synthesis of beta-(1?3) galactosides under sustainable conditions

beta-Gal-3 ATCC 31382 (beta-Gal-3) was immobilized by multipoint covalent attachment on an agarose support using different enzyme orientations on its surface. The derivatives that showed more activity and stability were the ones bound to a Lys rich region on a monofunctional glyoxyl-agarose (GA) support. Also, immobilization was performed using a Glu + Asp rich region on a heterofunctional amino-glyoxyl-agarose (AMGA) support. The immobilized enzyme was characterized in terms of optimal pH and thermal stability, and its catalytic efficiency was tested on the synthesis of beta-(1?3) galactosyldisaccharides. Reactions were performed in the presence of green solvents ([Bmim][PF6] and 2HNND) with maximum conversion and maintained regioselectivity. Reusability assays under identical reaction conditions were also performed to find that GA immobilized enzyme retains about 90% of its activity after six batches with conversion yields above 75% when [Bmin][PF6] was used as reaction media. Furthermore, green solvent recovery and recycling are achieved retaining catalytic activity and increased productivity.
