Chihara, Yuko published the artcileSerum-resistant Gene Transfer Activity of Mannosylated Dendrimer/α-Cyclodextrin Conjugate (G3), Application In Synthesis of 96345-79-8, the publication is Journal of Inclusion Phenomena and Macrocyclic Chemistry (2006), 56(1-2), 89-93, database is CAplus.

The purpose of this study is to evaluate in vitro gene transfer activity of polyamidoamine (PAMAM) starburst dendrimer (generation 3, G3) conjugate with α-cyclodextrin (α-CDE conjugate (G3)) bearing mannose (Man-α-CDE conjugate (G3)) with the degree of substitution of the mannose moiety 10 (DSM 10) as a novel non-viral vector in NIH3T3 and HepG2 cells. Man-α-CDE conjugate (G3) was found to have much higher gene transfer activity than dendrimer and α-CDE conjugate in NIH3T3 and HepG2 cells, which are independent of the expression of cell-surface mannose receptors. Gene transfer activity of Man-α-CDE conjugate (G3) was highly serum-resistant compared to that of dendrimer and α-CDE conjugate. No cytotoxicity after transfection of the complex of pDNA with Man-α-CDE conjugate (G3) was observed and the transfection activity was much higher than Lipofectin in NIH3T3 cells. These results suggest the potential use of Man-α-CDE conjugate (G3) as a non-viral vector.

Hibi, Takao published the artcilePurification of the functional plant membrane channel KAT1, Product Details of C14H28O5S, the publication is Biochemical and Biophysical Research Communications (2008), 374(3), 465-469, database is CAplus and MEDLINE.

The inward-rectifying K⁺ channel KAT1 is expressed mainly in Arabidopsis thaliana guard cells. The purification of functional KAT1 has never been reported. The authors investigated the extraction of the plant K⁺ channel KAT1 with different detergents, as an example for how to select detergents for purifying a eukaryotic membrane protein. A KAT1-GFP fusion protein was used to screen a library of 46 detergents for the effective solubilization of intact KAT1. Then, a “test set” of three detergents was picked for further anal., based on their biochem. characteristics and availability. The combination use of the selected detergents enabled the effective purification of functional KAT1 with affinity and gel-filtration chromatog.

Pardeshi, Chandrakantsing V. published the artcileMannose-anchored N,N,N-trimethyl chitosan nanoparticles for pulmonary administration of etofylline, Synthetic Route of 96345-79-8, the publication is International Journal of Biological Macromolecules (2020), 165(Part_A), 445-459, database is CAplus and MEDLINE.

Drug delivery to lungs via pulmonary administration offers potential for the development of new drug delivery systems. Here we fabricated the etofylline (ETO) encapsulated mannose-anchored N,N,N-tri-Me chitosan nanoparticles (Mn-TMC NPs). The prominent characteristics like biocompatibility, controlled release, targeted delivery, high penetrability, enhanced phys. stability, and scalability mark Mn-TMC NPs as a viable alternative to various nanoplatform technologies for effective drug delivery. Mannosylation of TMC NPs leads to the evolution of new drug delivery vehicle with gratifying characteristics, and potential benefits in efficient drug therapy. It is widely accepted that following pulmonary administration, the introduction of mannose to the surface of drug nanocarriers provide selective macrophage targeting via receptor-mediated endocytosis. The fabricated Mn-TMC NPs exhibited particle size of 223.3 nm, PDI 0.490, and ζ-potential -19.1 mV, drug-loading capacity 76.26 ± 1.2%, and encapsulation efficiency of 91.75 ± 0.88%. Sustained drug release, biodegradation studies, stability, safety, and aerodynamic behavior revealed the effectiveness of prepared nanoformulation for pulmonary administration. In addition, the in vivo pharmacokinetic studies in Wistar rat model revealed a significant improvement in therapeutic efficacy of ETO, illustrating mannosylation a promising approach for efficient therapy of airway diseases following pulmonary administration.

Hierrezuelo, J. M. published the artcileMicellar properties of a mixed surfactant system constituted by n-octyl-β-D-thioglucopyranoside and sodium dodecyl sulphate, Related Products of alcohols-buliding-blocks, the publication is Colloids and Surfaces, A: Physicochemical and Engineering Aspects (2005), 264(1-3), 29-36, database is CAplus.

A fluorescence probe study on micellization of the binary surfactant system formed by n-octyl-β-D-thioglucopyranoside (OTG) and Na dodecyl sulfate (SDS) in 0.1M NaCl aqueous solutions was carried out. The CMC exptl. data, as obtained by the pyrene 1:3 ratio method, were analyzed in the context of the pseudophase separation model. The interaction parameter (β₁₂) determined by using the regular solution theory (RST) is neg. and independent on the solution composition The exptl. data on micellar composition showed a good agreement with those predicted by RST. Data reported by a treatment based on the Gibbs-Duhem equation showed a reasonable agreement with those obtained by RST, suggesting that the mixed system behaves as a regular solution From the mixing thermodn. function values can be inferred that the electrostatic repulsions between the sulfate groups of SDS control the stability of the mixed micelles. Size of micelles was examined through the micellar aggregation number as obtained by the static quenching method. The aggregation number initially increases, giving a maximum value at low content of the ionic component, remaining almost constant at larger content of this one. This behavior was interpreted from the role played by the electrostatic repulsions between the headgroups of SDS in the stabilization of the mixed micelles. Finally, studies based on both pyrene 1:3 ratio index and intramol. excimer forming of 1,3-dipyrenylpropane solubilized in the micellar phase, reported information on the microenvironmental properties of mixed micelles. The results obtained were rationalized from 2 effects: the electrostatic repulsions between the headgroups of the ionic component and the micellar hydration.

Molina-Bolivar, J. A. published the artcileSurface Activity, Micelle Formation, and Growth of n-Octyl-β-D-Thioglucopyranoside in Aqueous Solutions at Different Temperatures, SDS of cas: 85618-21-9, the publication is Journal of Physical Chemistry B (2004), 108(34), 12813-12820, database is CAplus.

Micellization, surface activity, and structures of the aggregates of the nonionic surfactant n-octyl-β-D-thioglucopyranoside in aqueous solutions through a temperature range have been investigated. By using surface tension measurements, information was obtained on both changes in the critical micelle concentration and adsorption behavior in the air-liquid interface with the temperature These data were used to obtain the thermodn. properties of micellization along with the corresponding adsorption parameters in the air-liquid interface. The results obtained indicated that the surfactant headgroup has a more pronounced hydrophilic character than that of the common polyoxyethylenic nonionic surfactants. Size and structure of the micelles formed at different temperatures were investigated by light scattering measurements. The light scattering data, including static and dynamic experiments, account for micelle growth and hydration. The anal. of the exptl. results was focused on the phase transition from sphere to rodlike structures. To corroborate this point, addnl. measurements of d. and intramol. excimer formation of 1,2-dypyrenylpropane vs. the surfactant concentration were performed. Satisfactory agreement of the results, showing a significant micellar growth starting from a certain surfactant concentration, was observed by means of the different techniques used.

Naous, M. published the artcileSynergism in mixtures of n-octyl-β-D-thioglucoside and different n-alkyltrimethylammonium bromides: effect of the alkyl chain length, Synthetic Route of 85618-21-9, the publication is Colloid and Polymer Science (2012), 290(11), 1041-1051, database is CAplus.

Mixtures of n-octyl-β-D-thioglucoside with three different n-alkyltrimethylammonium bromides (n = 12 (DTAB), 14 (TTAB), and 16 (CTAB)) have been studied by using fluorescence spectroscopic techniques. The critical micelle concentration values of pure and mixed systems were determined by the pyrene 1:3 ratio method. The exptl. results were treated by using thermodn. mixing approaches based on the pseudo-phase separation model. All the mixed systems show a neg. deviation from ideal behavior, more pronounced with a larger alkyl tail of the co-surfactant. The three mixed systems fulfill the conditions of synergism, this behavior being also dependent on the alkyl chain length. By using the static quenching method, the mean micellar aggregation numbers of mixed micelles were obtained. In all the cases, the aggregation number is initially reduced with the participation of the cationic surfactant, remaining almost constant and close to the aggregation number of the pure cationic micelles. The local viscosity of pure and mixed micelles was examined by the photophys. response of the hydrophobic probe coumarin 6 solubilized in the micellar medium. The participation of the ionic component induces the formation of a less ordered structure than that of pure nonionic micelles. This effect becomes less pronounced as the chain hydrocarbon length of the co-surfactant increases.

Sawkar, Anu R. published the artcileGaucher Disease-Associated Glucocerebrosidases Show Mutation-Dependent Chemical Chaperoning Profiles, Category: alcohols-buliding-blocks, the publication is Chemistry & Biology (Cambridge, MA, United States) (2005), 12(11), 1235-1244, database is CAplus and MEDLINE.

Summary: Gaucher disease is a lysosomal storage disorder caused by deficient glucocerebrosidase activity. We have previously shown that the cellular activity of the most common Gaucher disease-associated glucocerebrosidase variant, N370S, is increased when patient-derived cells are cultured with the chem. chaperone N-nonyl-deoxynojirimycin. Chem. chaperones stabilize proteins against misfolding, enabling their trafficking from the endoplasmic reticulum. Herein, the generality of this therapeutic strategy is evaluated with other glucocerebrosidase variants and with addnl. candidate chem. chaperones. Improved chem. chaperones are identified for N370S glucocerebrosidase. Moreover, we demonstrate that G202R, a glucocerebrosidase variant that is known to be retained in the endoplasmic reticulum, is also amenable to chem. chaperoning. The L444P variant is not chaperoned by any of the active site-directed mols. tested, likely because this mutation destabilizes a domain distinct from the catalytic domain.
