S-Adenosylmethionine (AdoMet) concentrations are highly elevated in tissues and biol. fluids of patients affected by S-adenosylhomocysteine hydrolase deficiency. This disorder is clin. characterized by severe neurol. symptoms, whose pathophysiol. is not yet established. Therefore, we investigated the effects of intracerebroventricular administration of AdoMet on redox homeostasis, microglia activation, synaptophysin levels, and TAU phosphorylation in cerebral cortex and striatum of young rats. AdoMet provoked significant lipid and protein oxidation, decreased glutathione concentrations, and altered the activity of important antioxidant enzymes in cerebral cortex and striatum. AdoMet also increased reactive oxygen (2′,7′-dichlorofluorescein oxidation increase) and nitrogen (nitrate and nitrite levels increase) species generation in cerebral cortex. Furthermore, the antioxidants N-acetylcysteine and melatonin prevented most of AdoMet-induced pro-oxidant effects in both cerebral structures. Finally, we verified that AdoMet produced microglia activation by increasing Iba1 staining and TAU phosphorylation, as well as reduced synaptophysin levels in cerebral cortex. Taken together, it is presumed that impairment of redox homeostasis possibly associated with microglia activation and neuronal dysfunction caused by AdoMet may represent deleterious pathomechanisms involved in the pathophysiol. of brain damage in S-adenosylhomocysteine hydrolase deficiency. In the experiment, the researchers used many compounds, for example, 2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one (cas: 76-54-0Application In Synthesis of 2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one).

Pyrocatalysis-The DCF assay as a pH-robust tool to determine the oxidation capability of thermally excited pyroelectric powders was written by Raufeisen, Sascha;Stelter, Michael;Braeutigam, Patrick. And the article was included in PLoS One in 2020.Category: benzofurans This article mentions the following:

Pyrocatalysis uses thermally excited pyroelec. materials for the generation of reactive oxygen species in water. This unique feature allows it to harvest energy in the form of natural temperature gradients or waste heat from industrial processes in order to degrade organic pollutants at low costs. Its further development into an advanced oxidation process for water remediation is dependent on the availability of pH-robust and nonspecific redox assays for the determination of its oxidation capability. Nevertheless, previous studies neglected the influence of pH changes and they were focused mainly on the degradation of one organic compound or specific chem. dosimetries. In this study, a pH-robust and nonspecific reaction protocol of the dichlorofluorescein assay was established for the investigation of the oxidation capability of the pyrocatalytic process. This reaction protocol was tested on three pyroelec. powders (LiNbO3, LiTaO3, BaTiO3) in different amounts and it overcomes major constraints of a previously used dichlorodihydrofluorescein diacetate-based reaction protocol. Instead of its diacetate, dichlorodihydrofluorescein was used as fluorogenic probe and its concentration was drastically reduced to 1 μM. For the first time, these changes enable the determination and comparison of the oxidation capability independently of pH-rising processes, which are present for all investigated pyroelec. powders up to a pH of 11. Addnl., the precision of the dichlorofluorescein assay was drastically increased and the determination and consideration of autoxidation processes was enabled. Of all three pyroelec. powders, BaTiO3 exhibited the highest oxidation capability with a linear increase with respect to the powder amount In the experiment, the researchers used many compounds, for example, 2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one (cas: 76-54-0Category: benzofurans).

Metal-Organic Framework-Based Nanoagents for Effective Tumor Therapy by Dual Dynamics-Amplified Oxidative Stress was written by Chen, Jiajie;Wang, Yitong;Niu, Huicong;Wang, Yuwei;Wu, Aijun;Shu, Chaoqin;Zhu, Yufang;Bian, Yuhai;Lin, Kaili. And the article was included in ACS Applied Materials & Interfaces in 2021.Formula: C20H10Cl2O5 This article mentions the following:

Overproduction of reactive oxygen species (ROS) within tumors can cause oxidative stress on tumor cells to induce death, which has motivated us to develop ROS-mediated tumor therapies, such as typical photodynamic therapy (PDT) and Fenton reaction-mediated chemodynamic therapy (CDT). However, these therapeutic modalities suffer from compromised treatment efficacy owing to their limited generation of highly reactive ROS in a tumor microenvironment (TME). In this work, a nanoscale iron-based metal-organic framework, MIL-101(Fe), is synthesized as a Fenton nanocatalyst to perform the catalytic conversion of hydroxyl radicals (·OH) from hydrogen peroxide (H2O2) under the acidic environment and as a biocompatible and biodegradable nanocarrier to deliver a 5,10,15,20-tetrakis(4-carboxyphenyl)porphyrin (TCPP) photosensitizer for light-activated singlet oxygen (1O2) generation. By coupling such chemodynamic/photodynamic effects, the photosensitizer-integrated nanoagents (MIL-101(Fe)@TCPP) could enable more ROS production within tumors to induce amplified oxidative damage for tumor-specific synergistic therapy. In vitro results show that MIL-101(Fe)@TCPP nanoagents achieve the acid-responsive CDT and effective PDT, and synergistic CDT/PDT provides an enhanced therapeutic effect. Ultimately, based on such synergistic therapy, MIL-101(Fe)@TCPP nanoagents cause a significant tumor growth inhibition in vivo without severe side effects, showing great potential for anti-tumor application. In the experiment, the researchers used many compounds, for example, 2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one (cas: 76-54-0Formula: C20H10Cl2O5).

2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one (cas: 76-54-0) belongs to benzofurans derivatives. Benzofurans are compounds with a planar structure having 10 pi electrons that include the lone pair on oxygen atom, which makes it more susceptible to electrophilic attack. As benzofurans are prone to undergo ring opening of the heterocycle, examples of reduction of this type of aromatics by using dissolving metals are rather scarce.Formula: C20H10Cl2O5

Field applicable detection of hepatitis B virus using internal controlled duplex recombinase-aided amplification assay and lateral flow dipstick assay was written by Bai, Xueding;Ma, Xuejun;Li, Minghui;Li, Xinna;Fan, Guohao;Zhang, Ruiqing;Wang, Ruihuan;Duan, Qingxia;Shen, Xinxin;Xie, Yao;Rong, Xiuge. And the article was included in Journal of Medical Virology in 2020.Safety of 2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one This article mentions the following:

Hepatitis B virus (HBV) is a widespread blood-borne pathogen associated with the complication of liver cirrhosis and hepatocellular carcinoma, particularly in south-east Asian and African countries where HBV is highly endemic and the budget and resources are limited. Therefore, simple, rapid, and portable field detection methods are crucial to efficiently control HBV infection. In this study, using heat-treated DNA, we developed two-field applicable detection assays for HBV based on recombinase-aided amplification (RAA). One was an internal controlled duplex RAA assay using a portable real-time fluorescence detection device, another was an instrument-free visual observation assay using lateral flow dipsticks. The entire exptl. time was greatly shortened to less than 40 min at 39.0°C. The sensitivities, specificities, and clin. performance of both assays were evaluated. Compared with quant. polymerase chain reaction assay as a reference, our results demonstrated that the two RAA-based assay obtained 97.18% and 95.77% of sensitivity, resp., and the specificity was 100%, by testing a total of 157 serum samples with HBsAg pos. We conclude that the advantages of rapidity, simplicity, portability, and visualization of proposed two assays make them great potentials in point-of-care testing of HBV infection by untrained people in resource-limited situations.

Coffee-Derived Phenolic Compounds Activate Nrf2 Antioxidant Pathway in I/R Injury In Vitro Model: A Nutritional Approach Preventing Age Related-Damages was written by Lonati, Elena;Carrozzini, Tatiana;Bruni, Ilaria;Mena, Pedro;Botto, Laura;Cazzaniga, Emanuela;Del Rio, Daniele;Labra, Massimo;Palestini, Paola;Bulbarelli, Alessandra. And the article was included in Molecules in 2022.Safety of 2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one This article mentions the following:

Age-related injuries are often connected to alterations in redox homeostasis. The imbalance between free radical oxygen species and endogenous antioxidants defenses could be associated with a growing risk of transient ischemic attack and stroke. In this context, a daily supply of dietary antioxidants could counteract oxidative stress occurring during ischemia/reperfusion injury (I/R), preventing brain damage. Here we investigated the potential antioxidant properties of coffee-derived circulating metabolites and a coffee pulp phytoext., testing their efficacy as ROS scavengers in an in vitro model of ischemia. Indeed, the coffee fruit is an important source of phenolic compounds, such as chlorogenic acids, present both in the brewed seed and in the discarded pulp. Therefore, rat brain endothelial cells, subjected to oxygen and glucose deprivation (OGD) and recovery (ogR) to mimic reperfusion, were pretreated or not with coffee byproducts. The results indicate that, under OGD/ogR, the ROS accumulation was reduced by coffee byproduct. Addnl., the coffee extract activated the Nrf2 antioxidant pathway via Erk and Akt kinases phosphorylation, as shown by increased Nrf2 and HO-1 protein levels. The data indicate that the daily intake of coffee byproducts as a dietary food supplement represents a potential nutritional strategy to counteract aging.

Disposition of the waste sawdust substrate from sawdust-based cultivation of shiitake mushrooms (Lentinula edodes) is an important issue. In this study, we evaluated the physiol. activity in the water extracts of waste sawdust substrate which had been extracted, by the two-step hot/hot-compressed water percolation. The 180°C water extract of waste sawdust substrate contained some isoprenoid and high amounts of polyphenol. Addnl., high antioxidant activity was found in the 180°C water extract of the waste sawdust substrate in in vitro experiment (DPPH scavenging activity) and the human keratinocyte, HaCaT. This study suggested that the two-step hot/hot-compressed water percolation elutes the antioxidant components in the 180°C fraction from the waste sawdust substrate.

OBJECTIVE: To evaluate the effects of oxidative stress on insulin signaling in cardiac tissue of obese mice. METHODS: Thirty Swiss mice were equally divided (n=10) into three groups: Control Group, Obese Group, and Obese Group Treated with N-acetylcysteine. After obesity and insulin resistance were established, the obese mice were treated with N-acetylcysteine at a dose of 50mg/kg daily for 15 days via oral gavage. RESULTS: Higher blood glucose levels and nitrite and carbonyl contents, and lower protein levels of glutathione peroxidase and phosphorylated protein kinase B were observed in the obese group when compared with their respective control. On the other hand, treatment with N-acetylcysteine was effective in reducing blood glucose levels and nitrite and carbonyl contents, and significantly increased protein levels of glutathione peroxidase and phosphorylated protein kinase B compared to the Obese Group. CONCLUSION: Obesity and/or a high-lipid diet may result in oxidative stress and insulin resistance in the heart tissue of obese mice, and the use of N-acetylcysteine as a methodological and therapeutic strategy suggested there is a relation between them.

This study aimed to verify possible alterations involving histol. and oxidative stress parameters in the lungs of wild bats in the Carboniferous Basin of Santa Catarina (CBSC) state, Southern Brazil, as a means to evaluate the impact of coal dust on the health of wildlife. Specimens of frugivorous bat species Artibeus lituratus and Sturnira lilium were collected from an area free of coal dust contamination and from coal mining areas. Chem. composition, histol. parameters, synthesis of oxidants and antioxidant enzymes, and oxidative damage in the lungs of bats were analyzed. Levels of Na, Cl, Cu, and Br were higher in both species collected in the CBSC than in the controls. Levels of K and Rb were higher in A. lituratus, and levels of Si, Ca, and Fe were higher in S. lilium collected in the carboniferous basin. Both bat species inhabiting the CBSC areas exhibited an increase in the degree of pulmonary emphysema compared to their counterparts collected from control areas. Sturnira lilium showed increased reactive oxygen species (ROS) and 2′,7′-dichlorofluorescein (DCF) levels, while A. lituratus showed a significant decrease in nitrite levels in the CBSC samples. Superoxide dismutase (SOD) activity did not change significantly; however, the activity of catalase (CAT) and levels of glutathione (GSH) decreased in the A. lituratus group from CBSC compared to those in the controls. There were no differences in NAD(P)H quinone dehydrogenase 1 protein (NQO1) abundance or nitrotyrosine expression among the different groups of bats. Total thiol levels showed a significant reduction in A. lituratus from CBSC, while the amount of malondialdehyde (MDA) was higher in both A. lituratus and S. lilium groups from coal mining areas. Our results suggested that bats, especially A. lituratus, living in the CBSC could be used as sentinel species for harmful effects of coal dust on the lungs.

Bee pollen monofloral from Attalea funifera Mart., Arecaceae, known as piacava, was analyzed with ultra-performance liquid chromatog. coupled with diode array detector and quadrupole time-of-flight mass spectrometry for the profiling and structural characterization of the replicated compounds The principal compound was isolated and tested against Leishmania amazonensis. Fifty-eight compounds were identified, including one sugar, ten flavonoids, two putrescine derivatives, sixteen hydroxycinnamic acid amide derivatives, two coumarate derivatives, and twenty-seven lipids. The isolated compound identified as the biflavonoid rhusflavone showed high leishmanicidal activity against both promastigote (IC₅₀ = 5 μM) and amastigote (76.7% mortality at 2 μM) forms of L. amazonensis, acting via a mechanism involving reactive oxygen species production, mitochondrial dysfunction, and membrane disruption in parasites. The compound showed low toxicity to mammalian cells and human erythrocytes, with selectivity index for erythrocytes >100 and for macrophages (CC50 macrophages/IC₅₀ amastigotes) > 10.

All in one theranostic nanoagent based on MoSe₂/Au@PEG hollow nanospheres for the enhanced synergetic antitumor was written by Li, Yang;Wang, Limin;Kang, Keke;Ma, Yajie;Yu, Kai;Lu, Tong;Qu, Fengyu;Lin, Huiming. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2022.HPLC of Formula: 76-54-0 This article mentions the following:

MoSe2/Au@PEG nanoheterostructure were synthesized to integrate multi-imaging and therapeutic strategies into one nanoplatform. These Au nanoparticles were deposited on the surface of MoSe2 hollow nanospheres (250 nm) to reveal the enhanced NIR harvest owing to localized surface plasma resonance of Au, which could be varied with the particle sizes and the distance of Au nanoparticles. Therefore, MoSe2/Au@PEG nanocomposites revealed the great photothermal conversion efficiency to 73.0 %. In addition, they also exhibited the promoted reactive oxygen species (ROS) generation about 4-times as the pure sample, owing to the plasmon-mediated electron-transfer between the two components. Besides, the peroxidase and catalase activity of MoSe2 could convert the intracellular H2O2 to ·OH and O2 for chemotherapy. In addition, the glucose oxidase activity of Au made the H2O2 supplement for promoted chemodynamic therapy (CDT) and the glucose consumption for starvation therapy. It noted that the MoSe2/Au@PEG heterostructure also increased the nanozyme activity (2 times), ascribing to the decreased resistant of the charge transfer. The photothermal/photodynamic/starvation therapy combined with CDT could bring the immunogenic cell death that was associated with anti-CTLA4 to further arouse immune response to eliminate the primary as well as metastatic tumors. In addition, the novel biodegradation of the nanocomposite made the elimination via urine and feces within 18 d.
