In the search for improvement in the properties of gadolinium-based contrast agents, cyclodextrins (CDs) are interesting hydrophilic scaffolds with high molecular weight. The impact of the hydrophilicity of these systems on the MRI efficacy has been studied using five beta-CDs substituted with DOTA or TTHA ligands which, respectively, allow for one (q = 1) or no water molecule (q = 0) in the inner coordination sphere of the Gd3+ ion. Original synthetic pathways were developed to immobilize the ligands at C-6 position of various hydroxylated and permethylated beta-CDs via an amide bond. To describe the influence of alcohol and ether oxide functions of the CD macrocycle on the relaxation properties of the Gd3+ complexes, H-1 Nuclear Magnetic Relaxation Dispersion (NMRD) profiles, and O-17 transverse relaxation rates have been measured at various temperatures. The differences observed between the hydroxylated and permethylated beta-CDs bearing non-hydrated GdTTHA complexes can be rationalized by a second sphere contribution to the relaxivity in the case of the hydroxylated derivatives, induced by hydrogen-bound water molecules around the hydroxyl groups. In contrast, for the DOTA analogs the exchange rate of the water molecule directly coordinated to the Gd3+ is clearly influenced by the number of hydroxyl groups present on the CD, which in turn influences the relaxivity and gives rise to a very complex behavior of these hydrophilic systems.

Recently, a considerable amount of research is being directed towards study of graphene oxide (GO) and its reduced form (RGO) since their exposed functional groups make them better candidates in nanobiotechnolgy. In order to assess their biocompatibility, the nature of interactions between Human Hemoglobin (HHb) and GO/RGO are monitored since a comparative spectroscopic approach towards understanding their nature of interactions has not been investigated previously. UV-vis spectroscopy reveals hyperchromicity for HHb-GO systemand hypochromicity for HHb-RGO system in the region of absorption of tryptophan/tyrosine residues. Notably, although steady-state fluorescence static quenching of HHb for GO and enhancement of fluorescence for RGO is noticed, but average fluorescence-lifetime is remaining unchanged in presence of GO/RGO. Calorimetric data illustrates three-site and five-site binding model to be the best-fit model for GO and RGO respectively. Also, synchronous fluorescence quenching corresponding to alterations in microenvironment of tryptophan/ tyrosine residues is observed only in presence of GO. Likewise FTIR spectroscopy elucidates involvement of both amide I and amide II bond of HHb backbone through H-bonding interaction only for GO. Furthermore RLS spectra demonstrate an increase and a decrease in signal for GO and RGO respectively. Surprisingly, secondary structure of HHb is maintained upon interaction with both GO/RGO, as revealed by CD spectroscopy, thus supporting their potential application in biological microenvironment. Thus it appears that the spectroscopic properties of HHb upon interaction with GO is altered upon its reduction to RGO. Furthermore the role of HHb as good candidate for bimolecular interaction has been highlighted. (C) 2020 Elsevier B.V. All rights reserved.

N-Acylsuccinimides: twist-controlled, acyl-transfer reagents in Suzuki-Miyaura cross-coupling by N-C amide bond activation

The palladium-catalyzed Suzuki-Miyaura cross-coupling of N-acylsuccinimides as versatile acyl-transfer reagents via selective amide N-C bond cleavage is reported. The method is user-friendly since it employs commercially-available, air-stable reagents and catalysts. The cross-coupling is enabled by half-twist of the amide bond in N-acylsuccinimides. These highly effective, crystalline acyl-transfer reagents present major advantages over perpendicularly twisted N-acylglutarimides, including low price of the succinimide activating ring, selective metal insertion under redox neutral conditions and high stability of the amide bond towards reaction conditions. Mechanistic studies indicate that oxidative addition is the rate limiting step in this widely applicable protocol.

Determination of sodium picosulfate in enzyme products by high-performance liquid chromatography. tandem mass spectrometry

A method based on high-performance liquid chromatography-tandem mass spectrometry was developed for the determination of sodium picosulfate in enzyme products. Sodium picosulfate is a new slimming aid that is illegally added to food products. The existing analytical methods are not suitable for application to jellies and gel candies, thus triggering the need for developing a new method. The samples were extracted with water and passed through a poly- amide cartridge. The extracts were separated on a Thermo Accucore RP. MS column (100 mm x 2. 1 mm, 2. 6 mu m) using acetonitrile-10 mmol/L ammonium acetate solution (15 : 85, v/v) as the mobile phase. The flow rate of the mobile phase was 0.3 mL/min, and the column tempera. ture was 35 degrees C Detection was carried out in the multiple reaction monitoring (MRM) mode. Quantification analysis was performed by the external standard method. The results showed that sodium picosulfate had a good linear relationship in the range of 5- 500 mu g/L, and the correla. tion coefficient (r) was 0.. 999 9. The limit of detection (LOD) was 0.05 mg/kg. The average recoveries of sodium picosulfate in different matrices were in the range of 89.2% – 111.8%, with the relative standard deviations (RSDs) of 2.. 5% – 10.4%. The method was applied to the analy. sis of 152 samples, and 58 positive samples were detected. The positive rate was 38.2%. The developed method is accurate and sensitive, and it is suitable for detecting sodium picosulfate in enzyme products.

Polyelectrolyte complexes of sulfoethyl cellulose-chitosan: effect of the structure on separation properties of multilayer membranes

Membranes of a Simplex type with diffusion layers from sulfoethyl cellulose (SEC) and chitosan were investigated. Aromatic poly (amide imide) (PAI-O) synthesized by the low-temperature polycondensation from dicarboxyphenylphtalimide dichloranhydride and 4,4-diaminodiphenyl ether was used for the support preparation of the composite membrane. Porous support films with an average pore size in the skin layer of 8nm, were obtained from PAI-O under conditions of a phase-inversion process. Transport characteristics of membrane samples obtained were tested in processes of the aqueous ethanol pervaporation. All membranes are selective in the isolation of water from 96wt% ethanol solution. In the case of the SEC layer at the top of composite membrane the selectivity is very high and a water concentration in the permeate reaches 100wt%. The most selective membranes contained PEC based on counter-ions with the same degree of substitution of hydroxyl groups. The structure and morphological features of multilayer films studied by X-ray diffraction method, scanning electron microscopy and energy-dispersive X-ray microanalysis were discussed in view of a ratio of ionogenic groups of polyelectrolytes and a concentration of their solutions. The boundary of the counterion layers was visualized, as well as the polyelectrolyte complex (PEC). A formation of the PEC layer in the film obtained on a glass plate was shown to occur with the ordering of chitosan chains resulting both hydrated and anhydrous polymorphs, while the formation of the same film on the PAI-O substrate led only to the anhydrous form of chitosan.Graphical abstract [GRAPHICS] .

Simultaneous removal of hexavalent chromium and o-dichlorobenzene by isolated Serratia marcescens ZD-9

Heavy metals-organics mixture pollution is increasingly concerned and simultaneous removal of organic pollutants and heavy metals is becoming significant. In this study, a strain was isolated from the sediment of a tannery effluent outfalls, which can remove o-dichlorobenzene (o-DCB) and Cr(VI) simultaneously. The bacterial isolate was identified as Serratia marcescens by the 16S rRNA gene sequences. The strain removed about 90% of o-DCB and more than 80% of Cr(VI) at the concentration of 1.29gL(-1)o-DCB and 20mgL(-1) Cr(VI). In the presence of concomitant pollutant o-DCB, the optimal pH (8.0) and temperature (30 degrees C) were determined for Cr(VI) removal. Changes of the bacterial cells and intracellular black Cr(III) sediments were observed by the TEM auxiliary analysis. The results of the FTIR spectroscopy analysis indicated that hydroxyl, amide and polysaccharides were involved in the process of Cr(VI) removal.

Influence of UV radiation on molecular structure and catalytic activity of free and immobilized bromelain, ficin and papain

Our research has shown that the degree of photosensitivity of the cysteine proteases can be arranged in the following order: bromelain -> ficin -> papain. After the UV irradiation with 151 J.m(-2) intensity of a bromelain solution, the enzyme activity has increased. No decrease in the catalytic capacity and the change in the size of the molecule was recorded in the 151-6040 J.m(-2) range of irradiation intensities. A decrease in the catalytic capacity of ficin and the increase of its globule size occurred after exposure to a radiation of 3020 J.m(-2) intensity. The decrease in papain activity was observed at the UV irradiation intensity of 453 J.m(-2), and an increase of the papain globule size was detected at 755 J.m(-2). Immobilization on chitosan matrix leads to the increase in the stability of heterogeneous biocatalysts with respect to UV irradiation in comparison with free enzymes. The changes in IR spectra of immobilized cysteine proteases practically do not affect the bands due to the protein component of the system: amide I, amide II, amide III. Therefore, it can be postulated that the chitosan matrix acts as photoprotector for immobilized ficin, bromelain and papain. The obtained results can be helpful for development of drugs based on chitosan and cysteine proteases in combination with phototherapy, as well as for choosing their sterilization conditions.

A pH-Dependent, Mechanically Interlocked Switch: Organometallic [2]Rotaxane vs. Organic [3]Rotaxane

We present the first [2]rotaxane featuring a functional organometallic host. In contrast to the known organic scaffolds, this assembly shows a high post-synthetic modifiability. The reactivity of the Ag-8 pillarplex host is fully retained, as is exemplified by the first transmetalation in a rotaxane framework to provide the respective Au-8 analogue. Additionally, a transformation under acidic conditions to give a purely organic [3]rotaxane is demonstrated which is reversible upon addition of a suitable base, rendering the assembly a pH-dependent switch. Hereby, it is shown that the mechanically interlocked nature of the system enhances the kinetic stability of the NHC host complex by a factor of >1000 and corresponds to the first observation of a stabilizing rotaxand effect.
