Agarwal, Charu; Hofmann, Tamas; Pasztory, Zoltan published their research in Chemical Engineering and Processing on February 28 ,2021. The article was titled 《Low-frequency, green sonoextraction of antioxidants from tree barks of Hungarian woodlands for potential food applications》.Reference of ABTS Diammonium The article contains the following contents:

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. In the part of experimental materials, we found many familiar compounds, such as ABTS Diammonium(cas: 30931-67-0Reference of ABTS Diammonium)

Recommanded Product: ABTS DiammoniumOn March 4, 2020, Gaikwad, Adwait; Hlushko, Hanna; Karimineghlani, Parvin; Selin, Victor; Sukhishvili, Svetlana A. published an article in ACS Applied Materials & Interfaces. The article was 《Hydrogen-Bonded, Mechanically Strong Nanofibers with Tunable Antioxidant Activity》. The article mentions the following:

We report on mech. strong, water-insoluble hydrogen-bonded nanofiber mats composed of a hydrophilic polymer and a natural polyphenol that exhibit prolonged antioxidant activity. The high performance of fibrous mats resulted from the formation of a network of hydrogen bonds between a low-mol.-weight polyphenol (tannic acid, TA) and a water-soluble polymer (polyvinylpyrrolidone, PVP) and could be precisely controlled by the TA-to-PVP ratio. Dramatic enhancement (5- to 10-fold) in tensile strength, toughness, and Young’s moduli of the PVP/TA fiber mats (as compared to those of pristine PVP fibers) was achieved at the maximum d. of hydrogen bonds, which occurred at ∼0.2-0.4 M fractions of TA. The formation of hydrogen bonds was confirmed by an increase in the glass-transition temperature of the polymer after binding with TA. When exposed to water, the fibers exhibited composition- and pH-dependent stabilities, with the TA-enriched fibers fully preserving their integrity in acidic and neutral media. Importantly, the fiber mats exhibited strong antioxidant activity with dual (burst and prolonged) activity profiles, which could be controlled via fiber composition, a feature useful for controlling radical-scavenging rates in environmental and biol. applications. In addition to this study using ABTS Diammonium, there are many other studies that have used ABTS Diammonium(cas: 30931-67-0Recommanded Product: ABTS Diammonium) was used in this study.

Formula: C18H24N6O6S4On June 8, 2022, Chalmpes, Nikolaos; Patila, Michaela; Kouloumpis, Antonios; Alatzoglou, Christina; Spyrou, Konstantinos; Subrati, Mohammed; Polydera, Angeliki C.; Bourlinos, Athanasios B.; Stamatis, Haralambos; Gournis, Dimitrios published an article in ACS Applied Materials & Interfaces. The article was 《Graphene oxide-cytochrome C multilayered structures for biocatalytic applications: Role of surfactant in Langmuir-Schaefer layer deposition》. The article mentions the following:

Graphene, a two-dimensional single-layer carbon allotrope, has attracted tremendous scientific interest due to its outstanding physicochem. properties. Its monat. thickness, high sp. surface area, and chem. stability render it an ideal building block for the development of well-ordered layered nanostructures with tailored properties. Herein, biohybrid graphene-based layer-by-layer structures are prepared by means of conventional and surfactant-assisted Langmuir-Schaefer layer deposition techniques, whereby cytochrome C mols. are accommodated within ordered layers of graphene oxide. The biocatalytic activity of the as-developed nanobio-architectures toward the enzymic oxidation of 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt and decolorization of pinacyanol chloride is tested. The results show that the multilayer structures exhibit high biocatalytic activity and stability in the absence of surfactant mols. during the deposition of the monolayers. In the experimental materials used by the author, we found ABTS Diammonium(cas: 30931-67-0Formula: C18H24N6O6S4)

Halogenation, in which one or more hydrogen atoms of an amine is replaced by a halogen atom, occurs with chlorine, bromine, and iodine, as well as with some other reagents, notably hypochlorous acid (HClO). With primary amines the reaction proceeds in two stages, producing N-chloro- and N,N-dichloro-amines, RNHCl and RNCl2, respectively. With tertiary amines, an alkyl group may be displaced by a halogen.Formula: C18H24N6O6S4

And the article was published in Journal of the Serbian Chemical Society in 2019. Reference of ABTS Diammonium The author mentioned the following in the article:

The antiradical activity of L-3,4-dihydroxyphenylalanine (L-DOPA), dihydroxyphenylacetic acid (DOPAC), homovanillic acid and tyrosine towards 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt radi- cal (ABTS·-) was investigated exptl. and theor. by UV-Vis spectroscopy and the DFT theory. The importance of the catechol moiety for this reaction was proven due to the formation of intramol. hydrogen bond in the formed anions and radicals. The results indicated L-DOPA and DOPAC were more potent radical scavengers than homovanillic acid and tyrosine just because of intramol. hydrogen bond formation. Based on exptl. spectra, it was proved that electron transfer led to the reduction of ABTS·. The values of thermodn. parameters were used to predict the preferred mech- anism. The reaction rates were calculated for the electron transfer processes and it was shown that these were both kinetically and thermodynamically driven processes. Based on the reaction rate values, thermodn. para- meters, and present species, as determined by electronic spectra, it was con- cluded that single proton loss electron transfer (SPLET) is the dominant react- ion mechanism in the investigated system. After reading the article, we found that the author used ABTS Diammonium(cas: 30931-67-0Reference of ABTS Diammonium)

Reduction of nitro compounds, RNO2, by hydrogen or other reducing agents produces primary amines cleanly (i.e., without a mixture of products), but the method is mostly used for aromatic amines because of the limited availability of aliphatic nitro compounds. Reduction of nitriles and oximes (R2C=NOH) also yields primary amines.Reference of ABTS Diammonium

《Phytochemical profile and comparative anti-radical scavenging activities of n-hexane extracts of indigenous Zingiber officinale and Curcuma longa》 was written by Nweze, Chibuzo Carole; Dingwoke, Emeka John; Adamude, Fatima Amin; Nwobodo, Nwobodo Ndubuisi. Synthetic Route of C18H24N6O6S4 And the article was included in Free Radicals and Antioxidants in 2019. The article conveys some information:

Objectives: Free radical scavenging activities of n-haxane extracts of indigenous Curcuma longa and Zingiber officinale was investigated and compared to CellGevity; a nutraceutical antioxidant supplement. Methods: We used 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical, 2,2′-Azino-bis3-ethylbenzothialine-6-sulfonic acid (ABTS) radical cations and hydrogen peroxide (H2O2) to determine free radical scavenging activities of the extracts The ability of the extracts to scavenge free radicals was determined following the discoloration of the solution mixtures, measured spectrophotometrically. The reducing power efficacy of the extracts was determined by their ability to reduce Fe3+ to Fe2+ ions. Results:Curcuma longa and Zingiber officinale have more free radical scavenging power compared to CellGevity. Curcuma longa has more scavenging power against DPPH and H2O2 system, while Zingiber officinale has more scavenging power against ABTS cations. CellGevity had the least scavenging activity against the free radicals, as observed in this study. The highest phenolic, flavonoid, Vitamin C, Vitamin B1 and Vitamin B2 quantified were found in Curcuma longa and Zingiber officinale compared to CellGevity. Conclusion: The indigenous Curcuma longa and Zingiber officinale are natural sources of effective antioxidants with more scavenging power compared to a standard CellGevity nutraceutical.

ABTS Diammonium(cas: 30931-67-0) belongs to anime. Nitrous acid converts secondary amines (aliphatic or aromatic) to N-nitroso compounds (nitrosamines): R2NH + HNO2 → R2N―NO. Some nitrosamines are potent cancer-inducing substances, and their possible formation is a serious consideration when nitrites, which are salts of nitrous acid, are present in foods or pharmaceutical preparations. Tertiary amines give rise to nitrosamines more slowly; an alkyl group is eliminated as an aldehyde or ketone, along with nitrous oxide, N2O.Synthetic Route of C18H24N6O6S4

《Blue Light-Gated Reversible Silver Nanozyme Reaction Networks that Achieve Life-like Adaptivity》 was written by Jiang, Zhengxing; Li, Hua; Deng, Yuequan; He, Yi. Synthetic Route of C18H24N6O6S4 And the article was included in ACS Sustainable Chemistry & Engineering on April 6 ,2020. The article conveys some information:

Life is preserved by complex enzymic reaction systems. Inspired by life, here the authors report on the first example to fabricate blue light-gated reversible silver nanozyme reaction networks that achieve life-like adaptivity. Upon blue light excitation, silver nanoparticles (AgNPs) display oxidase-like activity in the presence of Cl- as a cofactor. The addition of Cl- promotes the separation between hot holes and electrons that are generated by excited-state surface plasmon of AgNPs, inducing the generation of highly reactive hydroxyl and superoxide anion radicals. They oxidize colorless 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)diammonium salt (ABTS) to yield green ABTS radicals (ABTS•+). It is shown that ABTS•+ is able to be reduced by AgNPs to regenerate ABTS when the blue light is turned off, and the reaction system returns to its initial state, which is the typical feature of the artificial adaptive system. The dynamic process of the adaptive system is tunable by changing the concentrations of AgNPs and Cl-, and it possesses excellent recyclable performance, which can be repeated at least six times. Overall, the silver nanozyme reaction networks are capable of responding to blue light stimuli and renewing by recycling to the initial state without blue light irradiation Inspired by enzymic reaction systems, blue light-gated reversible silver nanozyme reaction networks that achieve life-like adaptivity are successfully constructed.

HPLC of Formula: 30931-67-0On October 31, 2020 ,《Enzymatic depolymerization of industrial lignins by laccase-mediator systems in 1,4-dioxane/water》 appeared in Biotechnology and Applied Biochemistry. The author of the article were Dillies, Justine; Vivien, Celine; Chevalier, Mickael; Rulence, Alexandre; Chataigne, Gabrielle; Flahaut, Christophe; Senez, Vincent; Froidevaux, Renato. The article conveys some information:

Lignin is the second most abundant polymer after cellulose in lignocellulosic biomass. Its aromatic composition and recalcitrant nature make its valorization a major challenge for obtaining low mol. weight aromatics compounds with high value-added from the enzymic depolymerization of industrial lignins. The oxidation reaction of lignin polymer using laccases alone remains inefficient. Therefore, researches are focused on the use of a laccase-mediator system (LMS) to facilitate enzymic depolymerization Until today, the LMS system was studied using water-soluble lignin only (com. lignins, modified lignins, or lignin model compounds). This work reports a study of three LMS systems to depolymerize the three major industrial lignins (organosolv lignin, Kraft lignin, and sodium lignosulfonate). We show that an enzymic depolymerization of these lignins can be achieved by LMS using laccase from Trametes versicolor, 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt as mediator and a cosolvent (25% of 1,4-dioxane) to enhance the solubilization of lignins.

Wang, Dan; Lou, Jiangfei; Xu, Jin; Yuan, Jiugang; Wang, Qiang; Wang, Ping; Fan, Xuerong published an article in Environmental Science and Pollution Research. The title of the article was 《Degradation of octylphenol polyethoxylates with a long ethoxylate chain using the laccase-mediated systems》.Reference of ABTS Diammonium The author mentioned the following in the article:

Alkylphenol polyethoxylates (APEOn) are the second-largest category of com. nonionic surfactants, which are difficult to degrade naturally in the environment. This study examined the degradation of octylphenol polyethoxylate (OPEOn) by laccase and its laccase-mediated systems. The results showed that OPEOn was poorly degraded by laccase alone. 2, 2′-azino-bis [3-ethylbenzothiazoline-6-sulfonic acid] (ABTS), 1-hydroxybenzotriazole (HBT), and 2, 2, 6, 6-tetramethylpiperidine-1-oxyl (TEMPO) were selected as the redox mediators. Exptl. results also indicated that 52.4% of the initial OPEOn amount was degraded by laccase in the presence of TEMPO. The degradation efficiency was analyzed using high-performance liquid chromatog. Furthermore, the structural characteristics of the degradation products were measured using matrix-assisted laser desorption/ionization-time of flight mass spectrometry and NMR spectroscopy, and it could be found that the laccase-TEMPO system could gradually shorten the ethoxylate chain by oxidizing the primary hydroxyl group of OPEOn, thereby degrading the OPEOn of the macromol. into small mols. The maximum of the ion peak distributions of OPEOn decreased from n = 8 finally down to 3. The novel enzymic system introduced by this study will become a promising alternative method for high-efficiency APEOn conversion and had great potential value in wastewater treatment. The results came from multiple reactions, including the reaction of ABTS Diammonium(cas: 30931-67-0Reference of ABTS Diammonium)

HajKacem, Sihem; Galai, Said; Hernandez Fernandez, Francisco Jose; Perez de los Rios, Antonia; Smaali, Issam; Quesada Medina, Joaquin published an article on January 31 ,2020. The article was titled 《Bioreactor Membranes for Laccase Immobilization Optimized by Ionic Liquids and Crosslinking Agents》, and you may find the article in Applied Biochemistry and Biotechnology.HPLC of Formula: 30931-67-0 The information in the text is summarized as follows:

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.
