Agarwal, Charu published the artcileLow-frequency, green sonoextraction of antioxidants from tree barks of Hungarian woodlands for potential food applications, Quality Control of 30931-67-0, the publication is Chemical Engineering and Processing (2021), 108221, database is CAplus.

The present work evaluates and compares the antioxidant capacities of bioactive constituents in the barks of ten common wood species from Hungary (Quercus rubra, Prunus serotina, Quercus robur, Betula pendula, Fraxinus excelsior, Robinia pseudoacacia, Carpinus betulus, Picea abies, Alnus glutinosa, Pinus sylvestris). Low-frequency ultrasound was used for intensification of extraction from the bark to obtain extracts rich in polyphenolic antioxidants with potential applications in the food industry. The extractions were carried out in different aqueous organic solvents- ethanol 80% and acetone 80% at optimized conditions. The overall antioxidant capacity of the extracts was estimated by the combined evaluation of Folin-Ciocalteu total phenol content (TPC), 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and ferric reducing ability of plasma (FRAP) assays using a scoring system. Aqueous ethanol had better extraction efficiency than aqueous acetone as a solvent medium. Of all the investigated species, Quercus robur showed the maximum antioxidant capacity with TPC of 105.88 ± 17.75 mg GAE/g dw, DPPH (IC50) of 1.90 ± 0.10μg/mL, ABTS of 437.09 ± 36.22 mg TE/g dw and FRAP of 102.62 ± 8.69 mg AAE/g dw. The polyphenolic characterization of Quercus robur, Robinia pseudoacacia and Fraxinus excelsior was done by liquid chromatog./tandem mass spectrometry.

Tang, Yue published the artcileA facile colorimetric sensor for ultrasensitive and selective detection of Lead(II) in environmental and biological samples based on intrinsic peroxidase-mimic activity of WS2 nanosheets, Computed Properties of 30931-67-0, the publication is Analytica Chimica Acta (2020), 115-125, database is CAplus and MEDLINE.

Two-dimensional layered WS2 nanosheets with rich active edge exhibit intrinsic peroxidase-mimic activity, which make them an ideal material for sensor design. However, there is still lack of research on the catalysis and regulation mechanisms of the layered WS2 nanosheets as well as their application in the detection of hazardous substances. Herein, the regulatory effect of Pb(II) on the peroxidase-mimic activity of the layered WS2 nanosheets was firstly investigated, which enable us to construct a novel and facile colorimetric sensor for ultrasensitive and selective detection of Pb(II). To improve the performance of colorimetric sensor, some important parameters like buffer conditions, substrates and temperature have been investigated. Under the optimal conditions, the catalytic kinetics of layered WS2 nanosheets were extensively investigated. The peroxidase-mimic catalytic reaction was proved to be the “ping pong” mechanism, and the regulatory effect of Pb(II) on layered WS2 nanosheets was agreed with noncompetitive inhibition. The absorbance variation of colorimetric sensor is proportionally related to the concentration of heavy metals, which enable us to easily distinguish whether Pb(II) exceeds the permissible level in less than 20 min even by the naked eyes. The limit of detection (LOD) and the limit of quantification (LOQ) of the proposed colorimetric sensor for Pb(II) were determined as low as 4μg L-1 and 13.3μg L-1, and displays excellent selectivity against other competitive metal ions. Moreover, the further studies also validate the applicability of colorimetric sensor in several actual samples, indicating that our strategy may has prospective applications for Pb(II) detection in environment and biol. samples.

Wang, Rongrong published the artcileAnionic-Surfactant-Stabilized Hydrophobic Ionic-Liquid-Based Bicontinuous Microemulsion as a Medium for Enzymatic Oxidative Polymerization of Aniline, HPLC of Formula: 30931-67-0, the publication is ACS Omega (2021), 6(31), 20699-20709, database is CAplus and MEDLINE.

The hydrophobic ionic liquid [C8mim][PF6] (1-octyl-3-methylimidazolium hexafluorophosphate)-based bicontinuous microemulsion stabilized by the anionic surfactant [C4mim][AOT] (1-butyl-3-methylimidazolium bis(2-ethylhexyl) sulfosuccinate) was first tried as a medium for horseradish peroxidase (HRP)-triggered oxidative polymerization of aniline. The effects of the mass ratio of [C8mim][PF6]-to-water (α), the mass fraction of [C4mim][AOT] in the total mixture (γ), and temperature (T) on the enzymic polymerization were investigated using UV-vis-NIR absorption, ESR, and small-angle X-ray scattering spectroscopy techniques. The bicontinuous microemulsion is demonstrated to play a template role in the biosynthesis of polyaniline (PANI). The conductivity of the resulting PANI depends on the microemulsion microstructure and the microstructure- and T-dependent catalytic properties of the solubilized HRP. With the increase in α, the conductivity of the synthesized PANI decreases due to the increase in the template curvature (decrease of the microdomain size) and the decrease in the activity and stability of HRP. Compared with α, γ has little effect on the microdomain size of the template; so, the γ-dependent change in the conductivity of PANI is mainly caused by the changes of the microstructure-dependent activity and stability of HRP. Over the range of 20-35°C, T has little effect on the microdomain size, but it greatly changes the activity and stability of HRP. With the increase in T, the activity of HRP increases steadily, but its stability decreases significantly, which should be one of the reasons why the conductivity of PANI decreases with increasing T. In conclusion, lower values of α, γ, and T are favorable for the biosynthesis of conductive PANI. The present study not only deepens the insight into the role of the template in the process of PANI synthesis, but also opens up a green new way for the biosynthesis of the conducting polymer.

Nam, Jeongmin published the artcileEffect of crosslinkable bacterial cellulose nanocrystals on the physicochemical properties of silk sericin films, Product Details of C18H24N6O6S4, the publication is Polymer Testing (2021), 107161, database is CAplus.

The manufacture of eco-friendly cocoon silk-derived sericin films increases the availability of sericulture resources and the interest in expanding the range of the potential applications of sericin-based materials. However, the brittleness and weak tensile properties of sericin and its vulnerability to moist environments have limited its use. To overcome these two shortcomings of sericin, a functionalized bacterial cellulose-derived nanocrystal (average diameter: 25.4 nm) capable of phys. strengthening and chem. crosslinking on existing sericin films was prepared The improvement of the optical, physicochem., and mech. properties of the sericin film was observed through the dialdehyde bacterial cellulose nanocrystals (D-CNCs) incorporated into the silk sericin (SS) matrix. The phys. reinforcing effect of the D-CNCs on the SS films enhances the mech. properties of the films. Simultaneously, the chem. crosslinking reaction of D-CNCs develops the UV-blocking, water-resistant, and antioxidant properties of the films. The simultaneous fabrication, phys. reinforcement, and chem. crosslinking of the SS/D-CNCs biocomposite film produced using an aqueous solution will provide information on the functionalization and performance improvement of water-soluble biopolymeric materials, especially hydrophilic protein resources.

In previous research works, we have described the production of 7 kDa F5 peptide after a hydrolysis of the white shrimp, Metapenaeus monoceros (Fabricius, 1798) byproduct, using a serine alk. protease (SPVP) purified from Aeribacillus pallidus strain VP3. The present study aims to explore the antioxidative potentials of F5 peptide by both in vitro and in vivo assays. The anti-biofilm activity was performed, showing 50% inhibition at 2μg/mL, 3μg/mL, 19μg/mL, and 45μg/mL for Staphylococcus aureus, Escherichia coli, Bacillus cereus, and Pseudomonas aeruginosa, resp. Consistently, the antioxidative capacity was tested in vitro against 2,2′-azino-bis-(3-ethylbenz-thiazoline-6-sulfonic acid) (ABTS) cation radical, β-caroten-linoleic acid bleaching, chelating capacity of ferrous ion, and ferric reducing power assays. The cytotoxic effects of F5 peptide on the Human embryonic kidney HEK293 cells were subsequently tested. Remarkably, the F5 peptide was able to improve significantly HEK293 cell viability. To further assess this bioactivity, an in vivo study was performed on adult mice models. The animals were divided into three groups: controls, 100 mg and 200 mg of F5/kg per bodyweight. Indeed, the F5 peptide could prevent the lipid and protein oxidation damage in kidney cells, improving the antioxidative enzymic and non-enzymic capacities.

The mol. structures of 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), were calculated by using time-dependent d. functional theory (TDDFT) model with M062X method with 6-311G (d, p) basis set. In this work, the ABTS were theor. investigated from the geometric structure, the energy levels of the LUMO (LUMO) and the HOMO (HOMO), the energy level gap ΔEHOMO-LUMO of the mol. ground state, excited stated properties and the electronic absorption spectra of different oxidation states. We studied the energy levels of LUMO and HOMO of ABTS in different oxidation states. Frontier MO anal. can provide insight into the nature of excited states. ABTS was synthesized from N-ethylaniline by total synthesis. Then, we measured the UV-Vis spectra of ABTS before and after being oxidized by K2S2O8. The calculated electronic structures and photochem. properties of different oxidation state of ABTS were in accordance with the exptl. result. This work demonstrates the relationship between the electronic structures and photochem. of different oxidation states ABTS hence paves the way for the rationally synthesis and deepen understanding of the photophys. properties of ABTS materials.

This study reports an efficient and fast procedure for the purification of laccase (PaL) obtained from the resin of Pistacia atlantica Desf. It was purified by one-step affinity chromatog. and showed the specific activity of 393 U/mg with 81.9-fold purification The mol. weight of PaL was estimated to be approx. 60 kDa using gel electrophoresis SDS-PAGE. Moreover, it depicted diphenolase activity and high affinity towards 2,6-dimethoxy phenol (Km = 10.01 ± 0.5 mM) and syringaldazine (Km = 6.57 ± 0.2 mM) comparing with plant-origin polyphenol oxidases reported in the literature. It should be noted that PaL possessed optimal activity at pH 7.5 and 45°C. It also remained stable under different conditions of pH (6.5-8.0), temperature (25-45°C), and when it was exposed to several metal ions. The MTT and flow cytometry assays demonstrated that the enzyme treatment significantly affected growth of HeLa, HepG2, and MDA-MB-231 cells with LC50 values of 4.83 ± 0.02, 61 ± 0.31, and 26.83 ± 0.11μM after 72 h, resp. This is the first attempt to isolate and characterize a new oxidoreductase from the resin of Pistacia atlantica Desf., native species of Iran, to recruit it in cytotoxicity researches. In the purification process by an efficient affinity column (SBA-NH2-GA), the enzyme was eluted promptly with a satisfied yield. The purified laccase exerted higher affinity to diphenolic compounds and pH-thermal stability compared to other plant-derived polyphenol oxidases. The purified enzyme was found to show anti-oxidant capacity and significantly inhibited the growth of cancerous cells in vitro. PaL showed more cytotoxic activity towards HeLa and MDA-MB-231 cells by induction of apoptosis. The cytotoxic activity of the laccase was measured by flow cytometry.

ABTS, 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonate), is a common chromogenic substrate for peroxidase enzymes, which are widely used in biochem. research and diagnostic tests. We discovered that impurities in the com. available ABTS significantly affect the results of peroxidase activity assays. We show that the impurities inhibit the activity of the peroxidases and the influence varies for different batches of ABTS from the same source. The inhibition of horseradish peroxidase (HRP) is uncompetitive for the substrate H2O2 while it is competitive for the substrate ABTS. By using high-resolution mass spectrometry, potential inhibitors were identified to be precursors or analogs of ABTS. The inhibitors are also capable of inhibiting the GOx-catalyzed reduction of the ABTS radical cation by glucose in anaerobic conditions. As the inhibition is found to be pH-dependent, diagnostic applications, such as ELISA tests based on the peroxidase-H2O2-ABTS system, should be carried out at pH 4.4 to minimize the inhibitory effect of potentially present impurities.

A study on the dynamic change of the physicochem. properties and the active ingredients of kumquat fruits at different growth stages was carried out with Guangxi Rongan specialty Fortunella margarita (Lour.) ′Youpi′ (YP) and Fortunella margarita (Lour.) ′Cuipi′ (CP). The results showed that from Sept. to Dec., the phys. and chem. indexes such as single fruit weight, juice yield, pH value, soluble solids, and sugar-acid ratio of kumquat increased, and the fruit seed rate and titratable acid content decreased. The main sugar content rose from 39.04 and 32.38 mg/g to 111.23 and 137.11 mg/g, resp. The main organic acids were ascorbic acid, malic acid and oxalic acid, and the ascorbic acid content increased first and then decreased. In Oct., kumquat ascorbic acid content peaked (48.23 and 23.20 mg/g, resp.). While malic acid and oxalic acid contents continued to decline. Compared with Sept., the total flavonoid contents of YP and CP kumquat decreased from 3.45 and 2.14 mg RE/g to 1.21 and 0.76 mg RE/g resp. in Dec., in which the characteristic flavonoid fortunellin content increased significantly. The total phenol content and antioxidant activity decreased significantly. Between the two varieties, there were no significant differences in mature single fruit weight, titratable acid, TFs, and hesperidin content, and the fruit seed rate, ascorbic acid, fortunellin, TPs content, and total antioxidant capacity of YP were significantly higher than those of CP. While the juice yield, fruit juice pH, soluble solids, sugar-acid ratio, fructose, glucose, sucrose, malic acid, oxalic acid, and rutin content of YP were significantly lower than those of CP. This study clarifies the fruit quality characteristics of the two kinds of kumquat at different growth stages and provides a theor. basis for the development and utilization of kumquat fruit.

A novel concept of membrane bioreactor based on polymeric ionic liquids laccase membrane has been implemented in batch process for decolorization of the anthraquinonic dye Remazol Brillant Blue R (RBBR). New laccase immobilization strategy has been optimized by casting the enzyme into a polymeric inclusion membrane (PIM) using ionic liquids (ILs) and polyvinyl chloride (PVC) leading to laccase polymeric IL membrane (PILM). Four different ILs (1-octyl-3-metylimidazolium bis(trifluoromethylsulfonyl)imide, [OMIM][NTF2]; cholinium bis(trifluoromethylsulfonyl)imide, [Ch ol][NTF2]; cholinium dihydrogenphosphate, [Chol][H2PO4] and hydroxyethylammonium formate, [HEA][Fo]) have been screened and mixed to constitute the active phase of the support of PIM. This strategy has been fully succeeded since high laccase immobilization rates were recorded (about 98%) when using the optimal mixture containing three ILs (45% [OMIM][NTf2]/5% [Chol][NTf2]/2.5% [HEA][Fo]) and supplemented by 0.5% glutaraldehyde. It was found that such mixture contributes to increase the stability and reusability of laccase-PILM during eight successive assays in a batch discontinued stirred reactor. Decolorization rate of 75% has been reached in the batch decolorization process of RBBR with high reusability yield.
