Abstract (sommario):

Cyclodextrins are generated with a range of readily available enzymes for the treatment of ordinary starch. Along with amylase, cyclodextrin glycosylotransferase is commonly used. The first is to liquify starch by thermal treatment or amylase and add CGTase to the enzyme conversion. The synthesis of all three types of cyclodextrins is possible at ratios that depend strictly on the enzyme used. Each CGTase has an independent synthesis relationship. Cyclodextrins are filtered according to their different water solubility CDs that are very poorly water-soluble can be easily crystallised while the

Abstract (sommario):

ABSTRACT The hyperthermophilic archaeon Archaeoglobus fulgidus strain 7324 has been shown to grow on starch and sulfate and thus represents the first sulfate reducer able to degrade polymeric sugars. The enzymes involved in starch degradation to glucose 6-phosphate were studied. In extracts of starch-grown cells the activities of the classical starch degradation enzymes, α-amylase and amylopullulanase, could not be detected. Instead, evidence is presented here that A. fulgidus utilizes an unusual pathway of starch degradation involving cyclodextrins as intermediates. The pathway comprises the

Abstract (sommario):

Cyclodextrins are widely used for the solubilisation of poorly soluble drugs in the formulations. However, current cyclodextrin formulation development strongly depends on trial-and-error in the laboratory, which is time-consuming and high cost. The aim of this research was to compare three modeling approaches (Docking, molecular dynamics (MD), and quantum mechanics (QM)) for cyclodextrin/drug complexation. Ibuprofen was used as a model drug. Binding free energy from three simulation methods was calculated as an important parameter to compare with the experimental results. Docking results from

Reactions of amino-substituted cyclodextrins with bis(3-nitrophenyl) oxalate, malonate, succinate and glutarate, and with diphenyl carbonate, afford a range of linked cyclodextrins. These include α- and β-cyclodextrin dimers, joined by substitution at either C6 or C3, and asymmetric species with a β-cyclodextrin bonded to an a-cyclodextrin and a C3-substituted cyclodextrin attached to a C6-substituted moiety.

Abstract (sommario):

Background: Encapsulation of siRNA fragments inside liposome vesicles has emerged as an effective method for delivering siRNAs in vitro and in vivo. However, the liposome’s fluid-phospholipid bilayer of liposomes allows siRNA fragments to diffuse out of the liposome, decreasing the dose concentration and therefore the effectiveness of the carrier. We have previously reported that β-cyclodextrins formulated in liposomes help increase the stability of siRNAs in cell culture medium. Here, we continued that study to include α, γ, methyl-β-cyclodextrins and β-cyclodextrin-modified gold and selenium

Abstract (sommario):

Binding constants for the inclusion of sodium alkane-1-sulfonates (C5-C10, C12) by four modified β- cyclodextrins (2,6-O-dimethyl-β-cyclodextrin, 2,3,6-O-trimethyl-β-cyclodextrin, hydroxypropyl-β-cyclodextrin and maltosyl-β-cyclodextrin ) were determined conductimetrically at 25°C. Binding increased with increasing length of the alkyl chain. Generally, the substituted β- cyclodextrins were no more effective as encapsulating agents than ordinary β- cyclodextrin with the persubstituted 2,3,6-O-trimethyl-β-cyclodextrin being the weakest.

Abstract (sommario):

In recent years, our knowledge of the biological effects of cyclodextrins has grown significantly. Cellular actions of cyclodextrins originate in their ability to form complexes with lipophilic biomolecules. Cyclodextrins can target different types of molecules according to their size, for instance, alpha-cyclodextrins form complexes with phospholipids, while beta-cyclodextrins can bind cholesterol or prostaglandin E2. Due to their interactions with the main membrane constituents, cyclodextrins can affect the barrier function of biological barriers or influence the function of membrane protein

Abstract (sommario):

This Review summarizes the structures obtained when marrying synthetic polymers of varying architectures with cyclodextrins. Polymers with cyclodextrin pendant groups were obtained by directly polymerizing cyclodextrin-based monomers or by postmodification of reactive polymers with cyclodextrins. Star polymers with cyclodextrin as the core with up to 21 arms were usually obtained by using modified cyclodextrins as initiator or controlling agent. Limited reports are available on the synthesis of star polymers by arm-first techniques, which all employed azide-functionalized cyclodextrin and ‘cli

Lipophilic dialkylated-a-, β- and γ-cyclodextrin derivatives were used as selective ionophores for a series of clinically relevant ammonium ions, and as enantioselective ionophores for both a- and β-aryl ammonium ions. Sensitive and selective potentiometric detection of the local anaesthetics lidocaine and bupivacaine was achieved by using 2,3,6 trioctyl-β-cyclodextrin as the ionophore, leading to micromolar detection limits. Interference studies showed that the simulated clinical electrolyte background caused minimal interference whereas organic interferents of similar size and charge caused

For the investigation, we applied the rheological method using the rotation viscometer. In accordance with the structural properties, hydroxypropyl-ß-cyclodextrin reduces the mucoadhesion of the peptide while chitosan increases.

Abstract (sommario):

Objective. To evaluation the in vivo efficacy of chitosan as nasal absorption enhancers of peptides in rats and compare the results with that of hydroxypropyl- and dimethyl-Beta-cyclodextrins (HPBetaCD and DMBetaCD). Methods. Two types of chitosan. i.e., the free base (CSJ) and the glutamate salt form (CSG) were evaluated for their nasal absorption enhancing effect on salmon calcitonin (sCT) using an in vibo rat absorption technique. Solutions containing sCT and chitosan (0 to 1.25 % w/v) in isotonic phosphate buffers (pH 3.0 to 6.0) were nasally administered at the dose of 10 IU/kg. The plasm

Abstract (sommario):

Nifedupine solid dispersions in polyethylene glycols (PEG4000 and PEG6000), poloxamers (poloxamer188 poloxamer288 and poloxamer407), [beta]-cyclodextrin (BCD) and 2-hydroxypropyl-[beta]-cyclodextrin (HPBCD), at the drug:carrier ratio if 1:1, 1:3, 1:5, and 1:10 were investigated. The systems were prepared by melting, solvent and kneading method and compared to physical mixtures. It was found that the drug:carrier ratio of 1:10 and by melting and solvent methods showed most conspicuous dissolution rates in most systems (p<0.05). The most markedly improved rate was exhibited from the poloxamer
