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.

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.

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

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).

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.

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.

miR-381-3p inhibits high glucose-induced vascular smooth muscle cell proliferation and migration by targeting HMGB1 was written by Zhu, Xiao-Shan;Zhou, Han-Yun;Yang, Feng;Zhang, Hong-Shen;Ma, Ke-Zhong. And the article was included in Journal of Gene Medicine in 2021.Computed Properties of C20H10Cl2O5 This article mentions the following:

Hyperglycemia increases the risk of many cardiovascular diseases (CVD), and the dysregulation of proliferation and migration in vascular smooth muscle cells (VSMCs) also participates in the pathogenesis of CVD. miR-381-3p is known to suppress the proliferation and migration of multiple human cell types. Nevertheless, the function of miR-381-3p in VSMCs remains largely indistinct. A quant. real-time polymerase chain reaction (qRT-PCR) was employed to investigate miR-381-3p expression in high-glucose-induced VSMCs. Inflammatory cytokines tumor necrosis factor-α, interleukin-1β and interleukin-6, as well as oxidative stress markers SOD and MDA, were determined by an ELISA. Reactive oxygen species generation was examined using a 2,7′-dichlorofluorescein kit. The proliferation, migration and apoptosis of VSMCs were monitored by 3-(4,5-dimethylthiazl2-yl)-2,5-diphenyltetazolium bromide (MTT), transwell and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assays. The TargetScan database (http://www.targetscan. org) was employed to seek the potential target gene of miR-381-3p. Interaction between miR-381-3p and HMGB1 was determined by a qRT-PCR, western blotting and a luciferase reporter assay. MiR-381-3p expression was significantly reduced in a VSMCs dysfunction model induced by high-glucose in a dose- and time-dependent manner. Transfection of miR-381-3p mimics suppressed the inflammation, oxidative stress, proliferation and migration of VSMCs, whereas apoptosis of VSMCs was promoted, and the transfection of miR-381-3p inhibitors had the opposite effect. Mechanistically, HMGB1, an important factor in inflammation response, was confirmed as a target gene of miR-381-3p. MiR-381-3p targets HMGB1 to suppress the inflammation, oxidative stress, proliferation and migration of high-glucose-induced VSMCs by targeting HMGB1.

Dual-mode chemosensor for the fluorescence detection of zinc and hypochlorite on a fluorescein backbone and its cell-imaging applications was written by Maity, Sibaprasad;Maity, Annada C.;Das, Avijit kumar;Bhattacharyya, Nandan. And the article was included in Analytical Methods in 2022.Product Details of 76-54-0 This article mentions the following:

Fluorescein coupled with 3-(aminomethyl)-4,6-dimethylpyridin-2(1H)-one (FAD) was synthesized for the selective recognition of Zn²⁺ over other interfering metal ions in acetonitrile/aqueous buffer (1 : 1). Interestingly, there was a significant fluorescence enhancement of FAD in association with Zn²⁺ at 426 nm by strong chelation-induced fluorescence enhancement (CHEF) without interrupting the cyclic spirolactam ring. A binding stoichiometric ratio of 1 : 2 for the ligand FAD with metal Zn²⁺ was proven by a Jobs plot. However, the cyclic spirolactam ring was opened by hypochlorite (OCl-) as well as oxidative cleavage of the imine bond, which resulted in the emission enhancement of the wavelength at 520 nm. The binding constant and detection limit of FAD towards Zn²⁺ were determined to be 1 x 104 M^-1 and 1.79 μM, resp., and the detection limit for OCl^– was determined as 2.24 μM. We introduced here a dual-mode chemosensor FAD having both the reactive functionalities for the simultaneous detection of Zn²⁺ and OCl^– by employing a metal coordination (Zn²⁺) and analytes (OCl^–) induced chemodosimetric approach, resp. Furthermore, for the practical application, we studied the fluorescence imaging inside HeLa cells by using FAD, which demonstrated it can be very useful as a selective and sensitive fluorescent probe for zinc.

Thus, the objective of this study was to investigate the therapeutic effect of phonophoresis using diclofenac (DC) linked to gold nanoparticles (GNPs) in the skeletal muscle of rats used as a model of traumatic muscular injury. Wistar rats were divided into eight groups: Sham, Muscle injury (MI), MI + TPU, MI + DC, MI + GNPs, MI + TPU + DC, MI + TPU + GNPs, and MI + TPU + DC-GNPs. The traumatic injury was performed in the gastrocnemius with a single direct traumatic impact via an injuring press. The animals received daily treatment for 5 consecutive days with TPU and gel with DC and/or GNPs. Two hours after the last treatment session, animals were euthanized and the gastrocnemius muscle surgically removed for histol. and biochem. anal. Reactive species production and protein damage resulting from oxidative damage was lower for the group exposed to all tested therapies had lower production Lower protein damage was also observed in the TPU + GNPs group. The group that underwent all tested therapies combined showed a significant increase in antioxidants compared to the MI group. During histol. anal., the MI group showed large amounts of cell infiltration and centralized nuclei, whereas the MI + TPU + DC-GNPs group showed structural improvements. Pain levels in the MI + TPU + DC-GNPs group were lower than those of the MI group. We believe that the association of TPU with DC linked to GNPs decreases the inflammation caused by traumatic muscle injury and accelerates tissue repair.

Differential in vitro interactions of the Janus kinase inhibitor ruxolitinib with human SLC drug transporters was written by Bruyere, Arnaud;Le Vee, Marc;Jouan, Elodie;Molez, Stephanie;Nies, Anne T.;Fardel, Olivier. And the article was included in Xenobiotica in 2021.HPLC of Formula: 76-54-0 This article mentions the following:

The present study was therefore designed to investigate this issue. The interactions of ruxolitinib with SLCs were analyzed using transporter-overexpressing human embryonic kidney HEK293 cells. Substrate accumulation was detected by spectrofluorimetry, liquid chromatog. coupled to tandem mass spectrometry or scintillation counting. Ruxolitinib was found to potently inhibit the activities of organic anion transporter 3 (OAT3), organic cation transporter 2 (OCT2), multidrug and toxin extrusion 1 (MATE1) and MATE2-K (half maximal inhibitory concentration (IC50) < 10μM). It blocked OAT1, OAT4, OATP1B1, OATP1B3, OATP2B1 and OCT3, but in a weaker manner (IC50 > 10μM), whereas OCT1 was not impacted. No time-dependent inhibition was highlighted. When applying the US Food and Drug Administration (FDA) criteria for transporters-related drug-drug interaction risk, OCT2 and MATE2-K, unlike MATE1 and OAT3, were predicted to be in vivo inhibited by ruxolitinib. Cellular uptake studies addnl. indicated that ruxolitinib is a substrate for MATE1 and MATE2-K, but not for OAT3 and OCT2. Ruxolitinib in vitro blocked activities of most of SLC transporters. Only OCT2 and MATE-2K may be however clin. inhibited by the JAK inhibitor, with the caution for OCT2 that in vitro inhibition data were generated with an FDA-non recommended fluorescent substrate. Ruxolitinib MATEs-mediated transport may addnl. deserve attention for its possible pharmacol. consequences in MATE-pos. cells.
