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. 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: 76-54-0Product Details of 76-54-0).

“One-Pot” Synthesis of γ-Pyrones from Aromatic Ketones/Heteroarenes and Carboxylic Acids was written by Sun, Xiangyu;Gong, Ming;Huang, Mengmeng;Li, Yabo;Kim, Jung Keun;Kovalev, Vladimir;Shokova, Elvira;Wu, Yangjie. And the article was included in Journal of Organic Chemistry in 2020.Related Products of 38220-75-6 This article mentions the following:

Despite the various attractive properties of γ-pyrones, there are still some deficiencies in their synthetic approaches such as lower atom economy, multistep processes, and prefunctionalization of the reagents. In this work, an efficient and simple (CF₃CO)₂O/CF₃SO₃H-mediated “one-pot” approach was realized to produce γ-pyrones by applying aromatic ketones/heteroarenes and carboxylic acids as the starting materials. The target products were isolated in moderate to excellent yields. The reaction mechanism was studied by d. functional theory calculational methods. The results of exptl. and theor. investigations not only helped us explain the reason of high selectivity formation of β-diketones but also proved that 1,3,5-ketones might be important intermediates for the cyclization to afford γ-pyrones. In the experiment, the researchers used many compounds, for example, 1-(5-Bromobenzofuran-2-yl)ethanone (cas: 38220-75-6Related Products of 38220-75-6).

Effects of phonophoresis with diclofenac linked gold nanoparticles in model of traumatic muscle injury was written by Haupenthal, Daniela Pacheco dos Santos;Zortea, Diogo;Zaccaron, Rubya Pereira;Silveira, Gustavo de Bem;Correa, Maria Eduarda Anastacio Borges;Mendes, Carolini;Casagrande, Laura de Roch;Duarte, Mariane Bernardo;Pinho, Ricardo Aurino;Feuser, Paulo Emilio;Machado-de-Avila, Ricardo Andrez;Silveira, Paulo Cesar Lock. And the article was included in Materials Science & Engineering, C: Materials for Biological Applications in 2020.Application of 76-54-0 This article mentions the following:

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.

An examination of analysis of histamine in food for health risk management was written by Hanaishi, Ryuji;Yamamoto, Akemi. And the article was included in Aomori-ken Kankyo Hoken Senta Kenkyu Hokoku in 2019.Formula: C17H10O4 This article mentions the following:

A rapid anal. method of histamine in food for health risk management cases was explored. As a basic technique, the present authors adopted a method already reported by Kikuchi et al. (Hiroyuki Kikuchi et al., 2012), in which the eluted solution purified by solid-phase extraction using a C18 cartridge and a strongly acidic cation exchange resin cartridge was derivatized with fluorescamine. The method was modified using tetrabutylammonium hydroxide (TBAH) as a base in the eluted solution in the purification step to shorten the time required for anal. At the time of drawing a calibration line based on the results of standard solution measurement, percent differences were calculated and the ranges of the calibration line were determined, and spike recovery rates were calculated using sardine dried whole. Using the TBAH method, sufficient recovery rates were obtained, suggesting that the TBAH method was useful as an anal. method in health risk management. In the experiment, the researchers used many compounds, for example, 4-Phenyl-3H,3’H-spiro[furan-2,1′-isobenzofuran]-3,3′-dione (cas: 38183-12-9Formula: C17H10O4).

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.

Gram scale synthesis of Fe/Fe_xO_y core-shell nanoparticles and their incorporation into matrix-free superparamagnetic nanocomposites was written by Watt, John;Bleier, Grant C.;Romero, Zachary W.;Hance, Bradley G.;Bierner, Jessica A.;Monson, Todd C.;Huber, Dale L.. And the article was included in Journal of Materials Research in 2018.Name: 4-Phenyl-3H,3’H-spiro[furan-2,1′-isobenzofuran]-3,3′-dione This article mentions the following:

Significant reductions recently seen in the size of wide-bandgap power electronics have not been accompanied by a relative decrease in the size of the corresponding magnetic components. To achieve this, a new generation of materials with high magnetic saturation and permeability are needed. Here, we develop gram-scale syntheses of superparamagnetic Fe/Fe_xO_y core-shell nanoparticles and incorporate them as the magnetic component in a strongly magnetic nanocomposite. Nanocomposites are typically formed by the organization of nanoparticles within a polymeric matrix. However, this approach can lead to high organic fractions and phase separation; reducing the performance of the resulting material. Here, we form aminated nanoparticles that are then cross-linked using epoxy chem. The result is a magnetic nanoparticle component that is covalently linked and well separated By using this ‘matrix-free’ approach, we can substantially increase the magnetic nanoparticle fraction, while still maintaining good separation, leading to a superparamagnetic nanocomposite with strong magnetic properties.
