《Revealing the active site of gold nanoparticles for the peroxidase-like activity: the determination of surface accessibility》 was published in Catalysts in 2019. These research results belong to Liu, Ching-Ping; Chen, Kuan-Chung; Su, Ching-Feng; Yu, Po-Yen; Lee, Po-Wei. Related Products of 30931-67-0 The article mentions the following:

Despite the fact that the enzyme-like activities of nanozymes (i.e., nanomaterial-based artificial enzymes) are highly associated with their surface properties, little is known about the catalytic active sites. Here, we used the sulfide ion (S2-)-induced inhibition of peroxidase-like activity to explore active sites of gold nanoparticles (AuNPs). The inhibition mechanism was based on the interaction with Au(I) to form Au2S, implying that the Au(I) might be the active site of AuNPs for the peroxidase-like activity. XPS anal. showed that the content of Au(I) on the surface of AuNPs significantly decreased after the addition of S2-, which might be contributed to the more covalent Au-S bond in the formation of Au2S. Importantly, the variations of Au(I) with and without the addition of S2- for di erent surface-capped AuNPs were in good accordance with their corresponding peroxidase-like activities. These results confirmed that the accessible Au(I) on the surface was the main requisite for the peroxidase-like activity of AuNPs for the first time. In addition, the use of S2- could assist to determine available active sites for di erent surface modified AuNPs. This work not only provides a new method to evaluate the surface accessibility of colloidal AuNPs but also gains insight on the design of efficient AuNP-based peroxidase mimics.

《Carbohydrates profile, polyphenols content and antioxidative properties of beer worts produced with different dark malts varieties or roasted barley grains》 was published in Molecules in 2020. These research results belong to Gasior, Justyna; Kawa-Rygielska, Joanna; Kucharska, Alicja Z.. Safety of ABTS Diammonium The article mentions the following:

The aim of this study was to assess the possibility of shaping properties of beers at the stage of brewing wort production with the use of various types of special malts (chocolate pale, chocolate dark, wheat chocolate, brown barley) and roasted barley grains. The carbohydrate profile, polyphenols content, antioxidant capacity, 5-hydroxymethylfurfural content, and the browning index level were analyzed. Statistical anal. showed significant differences in the values of the examined features between the samples. The sugars whose content was most affected by the addition of special malts were maltose and dextrins. The polyphenol content in worts with 10% of additive was 176.02-397.03 mg GAE/L, ferric reducing antioxidant power (FRAP) 1.32-2.07 mmol TE/L, and capacity to reduction radical generated from 2,2′-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS•+) 1.46-2.70 mmol TE/L. Wort with 40% dark malt showed the highest content of polyphenolic compounds and antioxidant activity (FRAP and ABTS•+). The HMF content and the browning index value were higher for wort with the addition of darker-colored malts (EBC) and increased with increasing dark malt dose.

Due to unique properties of the nanoparticles (NPs) with biocompatibility, their application as drug in drug delievery and diagnostics, the recent scientific branch nanotechnol. has emerged as hope in modern medicine. Zinc oxide nanoparticles (ZnO NPs) have gained tremendous interest due to their potential use as chemotherapeutic and antimicrobial agents. They are included in the category of “”generally recognized as safe (GRAS) metal oxide””. There is an urgent need for developing addnl. sources of ZnO NPs. Therefore, in the present study 30 cyanobacterial extracts were screened for ZnO NPs synthesis.. The color change of the reaction mixture from blue to pale white indicated the synthesis of ZnO NPs. It was further confirmed by UV-Visible spectroscopy that showed the absorption peak at 372 nm. The SEM anal. during screening revealed that Oscillatoria sp. synthesized smallest ZnO NPs (∼40 nm) that were further optimized for their higher yield by altering reaction conditions (pH, temperature, reaction time, concentration of extract and metal precursor). Best conditions for ZnO NPs synthesis are (0.02 M zinc nitrate, 10 mL of extract volume, pH 8, at 80°C for 3 h). The NPs were purified through calcination at 350°C and characterized by UV-Vis, FTIR, XRD, SEM-EDAX, TEM, Zeta potential and DLS anal. The comparative anal. of purified biogenic ZnO NPs with com. chem. synthesized ZnO NPs (CS), exhibited their superior nature as antioxidant and anti-bacterial agent against both gram-pos. and gram-neg. bacteria. Synergistic effects of biogenic ZnO NPs and streptomycin addnl. favored for their future use as a potential biomedical agent.

Xing, Yanyan; Chen, Meiling; Zhao, Yunkun; Xu, Jiabi; Hou, Xiaohong published an article on January 31 ,2022. The article was titled 《Triple-enzyme mimetic activity of Fe3O4 @C@MnO2 composites derived from metal-organic frameworks and their application to colorimetric biosensing of dopamine》, and you may find the article in Microchimica Acta.Formula: C18H24N6O6S4 The information in the text is summarized as follows:

Novel Fe3O4 @C@MnO2 composites were successfully synthesized for the first time via an interfacial reaction between magnetic porous carbon and KMnO4, in which the magnetic porous carbon was derived from the pyrolysis of Fe-MIL-88A under N2 atmosphere. Interestingly, the obtained Fe3O4 @C@MnO2 composites were found to have triple-enzyme mimetic activity including peroxidase-like, catalase-like, and oxidase-like activity. As a peroxidase mimic, Fe3O4 @C@MnO2 composites could catalyze the oxidation of TMB into a blue oxidized product by H2O2. As a catalase mimic, Fe3O4 @C@MnO2 could catalyze the decomposition of H2O2 to generate O2 and H2O. As an oxidase mimic, Fe3O4 @C@MnO2 could catalyze the direct oxidation of TMB to produce a blue oxidized product without H2O2. Reactive oxygen species measurements revealed that the oxidase-like activity originated from 1O2 and O2-•and little•OH generated by the dissolved oxygen, which was catalyzed by the Fe3O4 @C@MnO2 in the TMB oxidation reaction. The oxidase-like activity of Fe3O4 @C@MnO2 was investigated in detail. Under the optimized conditions, a rapid, sensitive, visual colorimetric method for dopamine detection was developed based on the inhibitory effect of dopamine on the oxidase-like activity. The proposed method allows for dopamine detection with a limit of detection of 0.034μM and a linear range of 0.125-10μM. This new colorimetric method was successfully used for the determination of dopamine in human blood samples.

In this study, decolorization and degradation of malachite green dye was studied using the laccase immobilized pine needle biochar. Successful immobilization of biochar was achieved by adsorption and confirmed through SEM and energy dispersive X-ray anal. (SEM-EDX), Fourier transform IR spectroscopy (FTIR). High laccase binding of 64.4 U/g and high immobilization yield of 78.1% was achieved using 4U of enzyme at pH3 and temperature 30 °C. The immobilized laccase retained >50% relative activity in the pH range 2-7, >45% relative activity at 65 °C and >55% relative activity at 4 °C for 4 wk. The re-usability of immobilized enzyme was checked with 2, 2′-azino-bis 3-ethylbenzothiazoline-6-sulfonic acid (ABTS) substrate and enzyme retained 53% of its activity after 6 cycles. Immobilized laccase was used for the degradation and decolorization of azo dye malachite green in aqueous solution More than 85% removal of malachite green dye (50 mg/L) was observed within 5 h. FTIR and high performance liquid chromatog. (HPLC) anal. clearly indicated the breakdown of dye and presence of metabolites (leuco malachite green, methanone, [4-(di-Me amino)pheny]phenyl and 3-dimethyl-Ph amine) in gas chromatog.-mass spectrometry (GC-MS) anal. confirmed the dye degradation Phytotoxicity anal. indicated that the enzymic degradation resulted in lesser toxic metabolites than the original dye.

The article was titled 《New Quinoline-Urea-BenzΞothiazole Hybrids as Promising Antitubercular Agents: Synthesis, In Vitro Antitubercular Activity, Cytotoxicity Studies, and In Silico ADME Profiling》. The information in the text is summarized as follows:

A series of 25 new benzothiazole-urea-quinoline hybrid compounds, I (X = H, Me, F, NO2, etc.) and II (n = 0, 2, 3, 4, and 6) were synthesized successfully via a three-step synthetic sequence involving an amidation coupling reaction as a critical step. In vitro evaluation of these hybrid compounds for their antitubercular inhibitory activity against the Mycobacterium tuberculosis H37Rv pMSp12::GPF bioreporter strain was undertaken. Of the 25 tested compounds, 17 compounds exhibited promising anti-TB activities of less than 62.5μM (MIC90) and 13 compds showed promising activity with MIC90 values in the range of 1-10μM, while compound I(X = CF3), being the most active, exhibited sub-micromolar activity (0.968μM) in the CAS assay. In addition, minimal cytotoxicity against the HepG2 cell line (cell viability above 75%) in 11 of the 17 compounds, at their resp. MIC90 concentrations, was observed, with compound I(X = CF3), exhibiting 100% cell viability. The hybridization of the quinoline, urea, and benzothiazole scaffolds demonstrated a synergistic relationship because the activities of resultant hybrids were vastly improved compared to the individual entities. In silico ADME predictions showed that the majority of these compounds have drug-like properties and are less likely to potentially cause cardiotoxicity (QPlogHERG > -5).6-Chlorobenzothiazol-2-ylamine(cas: 95-24-9Safety of 6-Chlorobenzothiazol-2-ylamine) was used in this study.

Recommanded Product: ABTS Diammonium. The article was titled 《Nanoporous silk films with capillary action and size-exclusion capacity for sensitive glucose determination in whole blood》. The information in the text is summarized as follows:

In optical biosensing, silk fibroin (SF) appears as a promising alternative where other materials, such as paper, find limitations. Besides its excellent optical properties and unmet capacity to stabilize biomacromols., SF in test strips exhibits addnl. functions, i.e. capillary pumping activity of 1.5 mm s-1, capacity to filter blood cells thanks to its small, but tuneable, porosity and enhanced biosensing sensitivity. The bulk functionalization of SF with the enzymes glucose oxidase and peroxidase and the mediator ABTS produces colorless and transparent SF films that respond to blood glucose increasing 2.5 times the sensitivity of conventional ABTS-based assays. This enhanced sensitivity results from the formation of SF-ABTS complexes, where SF becomes part of the bioassay. Addnl., SF films triple the durability of most stable cellulose-based sensors. Although demonstrated for glucose, SF microfluidic test strips may incorporate other optical bioassays, e.g. immunoassays, with the aim of transferring them from central laboratories to the place of patient’s care.
