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.

Effects of SLCO1B1 and ABCB1 genotypes on the pharmacokinetics of atorvastatin and 2-hydroxyatorvastatin in healthy Korean subjects

Objective: This study aimed to evaluate the effect of genetic polymorphisms of SLCO1B1 and ABCB1 on the pharmacokinetics of atorvastatin and its metabolites. Methods: 290 Koreans were genotyped for SLCO1B1, ABCB1 and CYP3A5, and 28 subjects were selected for the pharmacokinetic study. Each subject received a single oral dose of 20 mg atorvastatin and blood samples were collected up to 48 hr after dosing. The relationship between the genotypes and atorvastatin pharmacokinetics was examined. Results: For SLCO1B1 genotypes, the mean area under the concentration-time curve from time 0 to infinity (AUC0-?) of atorvastatin was 148.2 ng ¡Á hr/ml for *15/*15 subjects (n = 3), which was significantly larger than for 1a/*15 and *1b/*15 (n = 8) (80.7 ng ¡Á hr/ml, p = 0.0121) and also larger than for *1a/*1a, *1a/*1b and *1b/*1b (n = 17) (66.3 ng ¡Á hr/ml, p = 0.0018). The mean AUC0-? of 2-hydroxyatorvastatin for *15/*15 was also larger than in *1a/*1a, *1a/*1b and *1b/*1b (p = 0.012). In lactone forms, no significant pharmacokinetic difference was found among the genotypes. For ABCB1 genotypes, the half-lives of atorvastatin, atorvastatin lactone, 2-hydroxyatorvastatin and 2-hydroxyatorvastatin lactone were significantly longer in c.2677TT-c.3435TT (n = 3) vs. c.2677GG-c.3435CC and c.2677GT-c.3435CT (n = 10), yielding p = 0.049, 0.007, 0.007 and 0.007, respectively. Conclusion: This study shows that the SLCO1B1*15 allele may be associated with the individual difference in the AUC0-? of atorvastatin whereas the ABCB1 TT-TT diplotype may affect the elimination half-life of the drug in the Korean population.

Synthesis of Manzamine C, Infractine and 6-Hydroxyinfractine

Manzamine C (1), a beta-carboline alkaloid with antitumor activity isolated from the marine sponge Haliclona sp. was synthesized.The dilithium derivative of 5-hexynoic acid (6) was alkylated with 7 to give after esterification the methyl 10-hydroxy-5-decynoate (8).The tosylate of 8 was converted into the azide 9 which could be selectively hydrogenated with Lindlar palladium catalyst to give the amino ester 10.Saponification of 10 and acylation with (Boc)2O yielded 11, which was converted with pentafluorophenol into 12.Removal of the Boc group in 12 gave an amino ester as intermediate, which cyclized immediately under high dilution conditions to give the lactam 13 in high yield.Reduction of 13 with LiAlH4 produced the macrocyclic amine 4.The beta-carboline part of 1 was prepared by condensation of N-benzyltryptamine 14 with the formylacetic acid equivalent 15 to give 16.Dehydrogenation of 16 with Pd-on-carbon catalyst led to the orthoester 17, which could be converted into the methyl ester 5 in high overall yield.The 4-(dimethylamino)pyridine-catalyzed substitution of the methyl ester function in 5 by the amine 4 gave the amide 29.The analogous reaction of 5 with pyrrolidine or with azacyclotridecane yielded 30 and 31.Reduction of these three amides with LiAlH4 produced 1, 2 and 3.The spectroscopic properties of 1 were identical with those of natural manzamine C. – Condensation of 14 or N-benzyl-5-(benzyloxy)tryptamine (19) with aldehyde 18 yielded the products 20 and 21, which could be dehydrogenated to furnish 22 and 23.From these the methyl esters 24 and 25 with properties identical to those of the known beta-carboline alkaloids infractine and 6-hydroxyinfractine could be obtained.
