In 2019,Polymers (Basel, Switzerland) included an article by Zhang, Shengming; Fang, Guizhen; Chen, Haitao; Lang, Qian. Recommanded Product: ABTS Diammonium. The article was titled 《The effect of degradation of soda lignin using Pd/SO42-/ZrO2 as a catalyst: improved reactivity and antioxidant activity》. The information in the text is summarized as follows:

To the value-added application of the soda lignin by improving its reactivity and antioxidant activity, a self-made Pd/SO42-/ZrO2 catalyst was used to catalyze the degradation reaction of soda lignin. The catalyst was loaded with the palladium of 1.47 weight% while retaining the super acidity of SO4 2-/ZrO2. The reaction condition was determined as follows: the dioxane-water solution was selected as the reaction solution, the addition amount of the catalyst was 5 weight% of the soda lignin, the system was heated at 100°C for 4 h under a hydrogen pressure of 3 MPa. The reactivity of the catalyzed-soda lignin compared to the soda lignin before the reaction was significantly improved: the values of phenolic hydroxyl groups and total hydroxyl groups were increased by 35.3% and 97.1%, resp., and the value of methoxy groups was decreased by 13%. Approx. 63.3% of the β-O-4 bonds were cleaved, which resulted in a reduction of the weight average mol. weight from 8200 g.mol-1 to 4900 gmol-1. At the same time, the EC50 values of the catalyzed-soda lignin on DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS+ 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonate) radicals scavenging were decreased by 20.6% and 32.6%, resp., and the reducing power of catalyzed-soda lignin at the absorption value of 0.5 was increased by 10.5%. The Pd/SO42-/ZrO2catalyst works by breaking the β-O-4 linkages and degrading the methoxy groups. The catalyzed-soda lignin exhibits the possibility of being used as the antioxidants, grafting precursors, adhesive additives, and raw materials for lignin/polymer composites.

《Redox Properties of Pyrogenic Dissolved Organic Matter (pyDOM) from Biomass-Derived Chars》 was written by Xu, Wenqing; Walpen, Nicolas; Keiluweit, Marco; Kleber, Markus; Sander, Michael. Product Details of 30931-67-0 And the article was included in Environmental Science & Technology on August 17 ,2021. The article conveys some information:

Chars are ubiquitous in the environment and release significant amounts of redox-active pyrogenic dissolved organic matter (pyDOM). Yet, the redox properties of pyDOM remain poorly characterized. This work provides a systematic assessment of the quantity and redox properties of pyDOM released at circumneutral pH from a total of 14 chars pyrolyzed from wood and grass feedstocks from 200 to 700°C. The amount of released pyDOM decreased with increasing pyrolysis temperature of chars, reflecting the increasing degree of condensation and decreasing char polarity. Using flow-injection anal. coupled to electrochem. detection, we demonstrated that electron-donating capacities (EDCpyDOM; up to 6.5 mmole-·gC-1) were higher than electron-accepting capacities (EACpyDOM; up to 1.2 mmole-·gC-1) for all pyDOM specimens. The optical properties and low metal contents of the pyDOM implicate phenols and quinones as the major redox-active moieties. Oxidation of a selected pyDOM by the oxidative enzyme laccase resulted in a 1.57 mmole-·gC-1 decrease in EDCpyDOM and a 0.25 mmole-·gC-1 increase in EACpyDOM, demonstrating a largely irreversible oxidation of presumably phenolic moieties. Non-mediated electrochem. reduction of the same pyDOM resulted in a 0.17 mmole-·gC-1 increase in EDCpyDOM and a 0.24 mmole-·gC-1 decrease in EACpyDOM, consistent with the largely reversible reduction of quinone moieties. Our results imply that pyDOM is an important dissolved redox-active phase in the environment and requires consideration in assessing and modeling biogeochem. redox processes and pollutant redox transformations, particularly in char-rich environments. In the part of experimental materials, we found many familiar compounds, such as ABTS Diammonium(cas: 30931-67-0Product Details of 30931-67-0)

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.Product Details of 30931-67-0

Sillero, Leyre; Prado, Raquel; Welton, Tom; Labidi, Jalel published their research in Sustainable Chemistry and Pharmacy on December 31 ,2021. The article was titled 《Extraction of flavonoid compounds from bark using sustainable deep eutectic solvents》.Application of 30931-67-0 The article contains the following contents:

The use of green solvents in extraction processes, especially for applications of lignocellulosic biomass, has been extensively studied over the last years. Among the range of different green solvents, deep eutectic solvents (DES) show promising results for extraction processes. Therefore, the aim of this work was the use of DES as additives in aqueous mixtures for the selective extraction of flavonoid compounds from the bark of Larix decidua. For this purpose, bark has been treated using different solvent ratios consisting of a DES/H2O mixture (0, 25, 50 and 75 wt%). Two DES were studied, choline chloride:urea and choline chloride:1,4-butanediol. In order to study the success of the extractions, the extracts and the remaining solid fraction were characterized. From the results, it was concluded that the choline chloride:1,4-butanediol (75 wt%) gave the best results, obtaining the richest extracts in flavonoids (383 mg CE/g dried bark extract), as well as those with the highest antioxidant capacity. These good results confirm the capacity of this DES to obtain active biomols. for further application. In the experiment, the researchers used many compounds, for example, ABTS Diammonium(cas: 30931-67-0Application of 30931-67-0)

The author of the article were Wang, Jing; Lu, Qiaoyun; Weng, Chenyuan; Li, Xiaoyun; Yan, Xiaoqiang; Yang, Wei; Li, Bingzhi; Zhou, Xuemin. The article conveys some information:

In this research, we attempted to develop a sensitive colorimetric sensing strategy for the detection of acid phosphatase (ACP) based on MnO2 nanosheets and explored its applications in screening and evaluating inhibitors of ACP. The MnO2 nanosheets exhibit intrinsic biomimetic oxidase activity, which can catalyze the oxidation of the colorless 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonate) diammonium salt (ABTS) into green oxidized ABTS (oxABTS). Upon the introduction of ACP, L-ascorbic acid-2-phosphate can be dephosphorylated to ascorbic acid, which arouses the disintegration of MnO2 nanosheets into Mn2+ ions. This disintegration weakens the enzyme mimicking activity of the MnO2 nanosheets, leading to the impediment of the oxidation of ABTS. Conversely, in the absence of ACP, the ABTS is rapidly oxidized by MnO2, leading to a significant colorimetric signal change. The absorbance difference at 420 nm displayed a linear relationship with the concentration of ACP ranging from 0.075 to 0.45 mU·mL-1, generating a detection limit of 0.046 mU·mL-1. In the inhibition assays, this sensing platform provided simple detection for parathion-Me (PM), a representative inhibitor of ACP. The facile evaluation of the inhibitory effect of PM, including its IC50 toward ACP, was also realized. The experimental part of the paper was very detailed, including the reaction process of ABTS Diammonium(cas: 30931-67-0Category: thiazole)

We present a technique for the simultaneous photostructuring of hydrogels on the μm scale with different compositions on one substrate. The existing methods (e.g. spin-coating of the hydrogel precursor and application of simple molds or spacers) have less potential to integrate spatially separated functional hydrogel dots as needed for the fabrication of complex polydimethylsiloxane (PDMS) on-glass microfluidic chips. Here, we report a method for the fast production of precisely placed hydrogel structures with adjustable height (= 80μm) and width (= 500μm) on glass substrates utilizing black polyoxymethylene molds. The integration of several chambers for different hydrogel precursor solutions in one mold allows the simultaneous photopolymerization of hydrogels with different compositions To visualize the difference in composition of the hydrogel dots and to demonstrate the precision in structuring, various quantum dots were added to the hydrogel precursor solutions and phys. entrapped during the photopolymerization To show the high potential of our photostructuring method, a microfluidic double-chamber reactor was designed and the variability in the performance of tri-enzymic cascade reactions with optionally spatially separated or non-separated enzymes β-galactosidase, glucose oxidase, and horseradish peroxidase was visualized.ABTS Diammonium(cas: 30931-67-0Product Details of 30931-67-0) was used in this study.

Abstract: The reported fluorescent dye-based artificial light-responsive oxidase mimics are suffering from their low catalytic efficiency. To overcome the limitation, we report the photooxidase-mimicking activity of Eosin Y which can catalyze the oxidation of various chromogenic substrates such as 3,3′,5,5′-tetramethylbenzydine (TMB), 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS), 3,3′-diaminobenzidine (DAB), and o-phenylenediamine (OPD) by dissolved oxygen. The photooxidase-like activity of Eosin Y is highly efficient for TMB substrate, and its catalytic efficiency is higher than that of the reported fluorescein (130 fold) and 9-mesityl-10-methylacridinium ion (7.7-fold) mimetic photooxidase. Moreover, the photosensitized Eosin Y-TMB chromogenic system is utilized for colorimetric detection of highly toxic and explosive sodium azide (NaN3) in a linear range from 5 to 500 μM with a limit of detection of 3.5 μM. The resulting colorimetric assay is selective and applied to determine NaN3 in real lake water samples.

《Programmable and Reversible Regulation of Catalytic Hemin@MOFs Activities with DNA Structures》 was written by Liu, Shuo; Yang, Mingjie; Guo, Weiwei. Electric Literature of C18H24N6O6S4 And the article was included in Chemical Research in Chinese Universities on April 30 ,2020. The article conveys some information:

Abstract: Metal-organic frameworks(MOFs)-based nanozyme plays an important role in biosensing, therapy and catalysis. In this study, the effects of single-stranded DNA(ssDNA) with programmable sequences and its complementary DNA(TDNA) on the intrinsic peroxidase-like activity of hemin loaded MOFs(UiO-66-2), denoted as hemin@UiO-66-NH2, were investigated. The hemin@UiO-66-2 exhibited improved catalytic activity compared with free hemin. However, the catalytic activity is inhibited in the presence of ssDNA, as ssDNA can be adsorbed by MOFs and therefore protected the active sites from contact with substrates. Upon the addition of the TDNA, double-stranded DNA(dsDNA) was formed and detached from the MOFs, resulting in the recovery of catalytic activity. Sequentially adding ssDNA or its complementary DNA strands can achieve the reversible regulation of the catalytic activity of MOFs nanozymes. Moreover, the DNA hybridization-based regulation was further applied to a cascaded catalytic system composed of the nanozyme, hemin@UiO-66-NH2, and glucose oxidase. These nanozyme based programmable and reversibly regulated catalytic systems may have potential applications in future smart biosensing and catalysis systems.

To elucidate the influence of methionine, which is an essential sulfur-containing amino acid, on the antioxidant activity of rice protein (RP), methionine was added to RP (RM). The addition of methionine to RM0.5, RM1.0, RM1.5, RM2.0, and RM2.5 was 0.5-, 1.0-, 1.5-, 2.0-, and 2.5-fold of methionine of RP, resp. Using the in vitro digestive system, the antioxidant capacities of scavenging free radicals (superoxide; nitric oxide; 2,2′-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt, ABTS), chelating metal (iron), and reducing power were investigated in the hydrolyzates of RP and RMs. Upon pepsin-pancreatin digestion, the weakest antioxidant capacity was produced by RP. With the addition of methionine, RMs exhibited more excellent responses to free radical scavenging activities and reducing power than RP, whereas RMs did not produce the marked enhancements in iron chelating activity as compared to RP. The present study demonstrated that RMs differently exerted the free radical scavenging activities that emerged in the protein hydrolyzates, in which the strongest scavenging capacities for ABTS, superoxide, and nitric oxide were RM1.5, RM2.0, and RM2.5, resp. Results suggested that the availability of methionine is a critical factor to augment antioxidant ability of RP in the in vitro gastrointestinal tract.

High activity and stability of immobilized enzymes have been constant pursuits and critical challenges for decades. Herein, Cytochrome c (peroxidase, Cyt c) and its corresponding enzyme mimic (Pd nanoparticles) were combined and successfully embedded into a zeolitic imidazolate framework-8 (ZIF-8) to enhance the enzymic catalytic performance using a biomimetic mineralization approach. Owing to allosteric effects of Cyt c-Pd complexes, the as-synthesized Cyt c-Pd@ZIF-8 composites exhibit an increased turnover number (approx. 2.4-fold for kcat) and an enhanced catalytic efficiency (approx. 2.3-fold for kcat/KM) compared to free Cyt c; also the shielding effect of ZIF-8 endows enzyme with improved resistance against harsh conditions (e.g. high temperatures and organic solvents). The strategy, which integrates enzyme with its enzyme mimic derived from transition metal nanoparticles to enhance enzymic catalytic performances, may provide a versatile and facile technique for designing highly efficient and multi-functional bio-catalysts.
