In silico analyses of essential interactions of iminosugars with the Hex A active site and evaluation of their pharmacological chaperone effects for Tay-Sachs disease

The affinity of a series of iminosugar-based inhibitors exhibiting various ring sizes toward Hex A and their essential interactions with the enzyme active site were investigated. All the Hex A-inhibiting iminosugars tested formed hydrogen bonds with Arg178, Asp322, Tyr421 and Glu462 and had the favorable cation-pi interaction with Trp460. Among them, DMDP amide (6) proved to be the most potent competitive inhibitor with a K-i value of 0.041 mu M. We analyzed the dynamic properties of both DMDP amide (6) and DNJNAc (1) in aqueous solution using molecular dynamics (MD) calculations; the distance of the interaction between Asp322 and 3-OH and Glu323 and 6-OH was important for stable interactions with Hex A, reducing fluctuations in the plasticity of the active site. DMDP amide (6) dose-dependently increased intracellular Hex A activity in the G269S mutant cells and restored Hex A activity up to approximately 43% of the wild type level; this effect clearly exceeded the border line treatment for Tay-Sachs disease, which is regarded as 10-15% of the wild type level. This is a significantly greater effect than that of pyrimethamine, which is currently in Phase 2 clinical trials. DMDP amide (6), therefore, represents a new promising pharmacological chaperone candidate for the treatment of Tay-Sachs disease.

Development of alginate gel beads with a potential use in the treatment against acute lead poisoning

The objective was to develop alginate beads that could adsorb lead ions in gastric pH, in view to preconize their use in gastric lavage following lead poisoning. The swelling measurements of both, dry and hydrated beads, were carried out in simulated gastric fluid (SGF). The sorption kinetics was examined at lead concentrations ranging from 50 to 200 mg/l. Calcium released during the sorption process was investigated. The swelling rate of the dry beads increased considerably with time increase and reached the equilibrium at 736% after 240 min; concerning the hydrated beads, the equilibrium swelling reached 139% after 180 min. The adsorption of Pb (II) in SGF by dry beads increased with the increase of time and initial lead concentration. The adsorption kinetics of Pb ions by hydrated alginate beads indicated a rapid binding of Pb ions to the sorbent during the first 15 min for all the concentrations, followed by a slow increase until the equilibrium was reached after 90 min. The adsorption capacity of Pb ions increased with the increase of the storage time in water at 4 degrees C and with the weight. The amount of Ca2+ released by the beads increased with the increase of Pb ions a rate. (C) 2017 Elsevier B.V. All rights reserved.

Measuring Solvent Hydrogen Exchange Rates by Multifrequency Excitation N-15 CEST: Application to Protein Phase Separation

Solvent exchange rates provide important information about the structural and dynamical properties of biomolecules. A large number of NMR experiments have been developed to measure such rates in proteins, the great majority of which quantify the buildup of signals from backbone amides after initial perturbation of water magnetization. Here we present a different approach that circumvents the main limitations that result from these classical hydrogen exchange NMR experiments Building on recent developments that enable rapid recording of chemical exchange saturation transfer (LEST) pseudo-3D data sets, we describe a N-15-based CEST scheme for measurement of solvent exchange in proteins that exploits the one-bond N-15 deuterium isotope shift. The utility of the approach is verified with an application to a 236 residue intrinsically disordered protein domain under conditions where it phase separates and a second application involving a mutated form of the domain that does not phase separate, establishing very similar hydrogen exchange rates for both samples. The methodology is well suited for studies of hydrogen exchange in any N-15-labeled biomolecule. A discussion of the merits of the CEST experiment in relation to the popular CLEANEX-PM scheme is presented.

Green synthesis and biological activities of gold nanoparticles functionalized with Salix alba

This study reports a facile and reproducible green extracellular synthetic route of highly stable gold nanoparticles. The aqueous gold ions when exposed to Salix alba L. leaves extract were bioreduced and resulted in the biosynthesis of gold nanoparticles (Au-WAs). The nanoparticles were characterized by UV-Visible spectroscopy (UV-Vis), Fourier transform infrared spectroscopy (FTIR), atomic force microscopy (AFM) and scanning electron microscopy (SEM). Their stability was evaluated against varying volumes of pH and sodium chloride as well as at elevated temperature along with enzymes inhibition, antibacterial, antifungal, anti-nociceptive, muscle relaxant and sedative activities. The UV-Vis spectra of the gold nanoparticles gave surface plasmon resonance at 540 nm while the AFM and SEM nanoparticles analyses revealed the particle size of 63 nm and 5080 nm respectively. FTIR spectra confirmed the involvement of amines, amide and aromatic groups in capping and reduction of the gold nanoparticles. Au-WAs showed remarkable stability in different volumes of salt and various pH solutions however, Au-WAs were relatively unstable at elevated temperature. Au-WAs possessed good antifungal activity and showed significant antinociceptive and muscle relaxant properties. These results revealed that the leaves extract of S. alba is a very good bio-reductant for the synthesis of gold nanoparticles that have potential for various biomedical and pharmaceutical applications.

Chiral Discrimination by a Binuclear Pd Complex Sensor Using P-31{H-1} NMR

An axially chiral binuclear mu-hydroxo Pd complex (BPHP) first served as an excellent chiral sensor for discriminating a variety of analytes including amino alcohol, amino amide, amino acid, mandelic acid, diol, diamine, and monoamine by P-31{H-1} NMR A detailed recognition mechanism was proposed based on the single crystal and mass spectrum of Pd-complexes. In general, BPHP sensor, through extracting the acidic hydrogen of an analyte by its Pd-OH group, forms stable diastereomeric complexes with two enantiomers of the analyte giving well distinguishable split P-31{H-1} NMR signals for chiral discrimination.

From 2-to 3-Substituted Ferrocene Carboxamides or How to Apply Halogen Dance to the Ferrocene Series

Two methods were compared to convert ferrocene into N,N-diisopropylferrocenecarboxamide, N,N-diethylferrocenecarboxamide, N,N-dimethylferrocenecarboxamide, and (4-morphohnocarbonyl)ferrocene, namely, deprotometalation followed by trapping using dialkylcarbamoyl chlorides and amide formation from the intermediate carboxylic acid. The four ferrocene-carboxamides were functionalized at C-2; in the case of the less hindered and more sensitive amides, recourse to a mixed lithium-zinc 2,2,6,6-tetramethylpiperidino-based base allowed us to achieve the reactions. Halogen migration using lithium amides was next optimized. Whereas it appeared impossible to isolate the less hindered 3-iodoferrocenecarboxamides, 3-iodo-N,N-diisopropylferrocenecarboxamide proved stable and was converted to new 1,3-disubstituted ferrocenes by Suzuki coupling or amide reduction. DFT calculations were used to rationalize the results obtained.

Graphene oxide (GO), an inexpensive, environment-friendly, and metal-free carbocatalyst, used for the N-formylation of amines is developed. In this reaction, GO shows good activity, selectivity, and recyclability. This strategy has an array of advantages, such as being metal free, without additive, wide-scope protocol, scalable with a low catalyst loading of 3wt%, use of readily available and recyclable carbocatalyst, and DMF as a readily available formyl source. Furthermore, this strategy provides an avenue for the convenient hydroformylation of various amines. [GRAPHICS]

Role of Coordination Structure of Magnesium Ions on Charge and Discharge Behavior of Magnesium Alloy Electrode

Mechanism of magnesium ion alloying reaction into bismuth electrode in magnesium bis(trifluoromethanesulfonyl)amide (Mg(TFSA)(2))/acetonitrile (AN) and Mg(TFSA)(2)/2-methyltetrahydrofuran (2-MeTHF) electrolyte was examined by a combination of operando soft X-ray absorption spectroscopy (XAS), Raman spectroscopy, and density functional theory 8 anode (DFT) calculations. In 0.5 M Mg(TFSA)(2)/AN, the magnesium ions alloying reaction occurred, whereas the alloying reaction did not occur in 0.5 M Mg(TFSA)(2)/2-MeTHF. Raman spectroscopy showed that less than 15% of [TFSA](-) coordinates with magnesium ions in 0.5 M Mg(TFSA)(2)/AN, while more than 90% of [TFSA](-) coordinates with magnesium ions in Mg(TFSA)(2)/2-MeTHF. Using operando XAS measurements, we observed that electronic and local structure of magnesium ion changed similarly upon cathodic polarization in both electrolytes. These results indicate that the difference of the behavior of alloy formation should be affected by the difference of coordinate structure of [TFSA](-) in both electrolytes. Our DFT calculation results indicates [TFSA](-) coordinated to magnesium ions undergoes reduction decomposition more easily than [TFSA](-) uncoordinated to magnesium ions. In 0.5 M Mg(TFSA)(2)/2-MeTHF, the [TFSA](-) coordinating to magnesium ions undergoes reduction decomposition, which inhibits the alloying reaction into the bismuth electrode. On the other hand, in 0.5 M Mg(TFSA)(2)/AN, the [TFSA](-) reduction decomposition occurs relatively slowly because of the weak coordination between [TFSA](-) and magnesium ions, which allows the magnesium ions alloying into the bismuth electrode in the electrolyte.
