Inflammatory responses are generated against the danger molecules under normal conditions but excessive or chronic inflammation leads to tissue degeneration and loss of function. To prevent the disease symptoms associated with the inflammatory disorders or the growth of tumor types that require inflammatory environment, generation of immunomodulatory drugs with suppressive functions have great potentials. In this study, we synthesized new generation of anti-proliferative bis-benzoxazole derivatives and tested their anti-inflammatory and anti-cancer potencies. For this purpose, we used a well-characterized mouse macrophage cell line (RAW 264.7). Furthermore, anti-cancer activity of these compounds were tested using MTT assay on prostate (DU145) and breast (MCF7) cancer cells. The screening results revealed that all compounds possessed a high-level anti-inflammatory potential by reducing the expression of inflammatory cytokines in LPS-stimulated macrophages. There were significant and substantial reductions in the secreted TNF alpha, IL6, and IL1 beta levels by chemically treated LPS-induced macrophages compared to non-treated induced ones. Our compounds exerted their anti-inflammatory effect in a dose-dependent manner and they were biologically active even in low nanomolar range concentrations. Bis-benzoxazole derivatives had anti-proliferative effect on MCF-7 and DU-145 cancer cells. Together, our results present a series of new bis-benzoxazole-based compounds with potential therapeutic effects in inflammatory diseases and on tumor cells.

New discoveries in chemical research and development in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 273-53-0, Name is Benzoxazole, molecular formula is C7H5NO. In an article, author is Aguilar-Lugo, Carla,once mentioned of 273-53-0, Category: benzoxazole.

A new nucleophilic monomer (2,2-bis(3-amino-4-hydroxyphenyl)adamantane, ADHAB) having bulky adamantane groups has been synthesized following an efficient synthetic methodology. The main target of this work was to employ a high thermal stable bulky cycloaliphatic moiety as adamantane to obtain aromatic ortho-hydroxypolyimides (poly(o-hydroxyimide)s) able to thermally rearrange to give polybenzoxazole (TR-PBO) materials that could be tested as gas separation membranes. Thus, an array of ortho-acetylcopolyimides, o-acetyl PIs) were prepared by reaction of ADHAB and 2,2-bis(3-amino-4-hydroxyphenyl)hexafluoropropane (APAF) with 2,2-bis(3,4-dicarboxyphenyl)hexafluoropropane dianhydride (6FDA) via chemical imidization. Copolyimides and homopolyimides showed inherent viscosities ranging from 0.49 to 0.70 dL/g and provided good-quality dense membranes. Glass transition temperatures of these o-acetyl copolyimides were higher as the amount of ADHAB increased. The thermal stability of the adamantane moiety during the TR process was evaluated by directly synthesizing PBOs, which were made from the reaction, and ulterior thermal cyclization, of 2,2-bis(4-chlorocarbonylphenyl)-hexafluoropropane with ADHAB/APAF. TR-PBO membranes made through a thermal treatment at 450 degrees C for 30 min showed excellent gas separation properties for the CO2/CH4 gas pair with values close to the 2008 Robeson limit.

Herein, we fabricated two types of electrospun membrane using: 1) sulfonated poly (arylene ether sulfone), which needs chemical cross-linking to increase its mechanical strength, and 2) thermally rearranged poly (benzoxazole-co-imide), which is mechanically robust while requiring the hydrophilic coating. With a high porosity and low structure parameter of the support layer, two thin film composite (TFC) membranes were fabricated via interfacial polymerization on the support layer using 1,3,5-bezenetricarbonyl trichloride (TMC) and m-phenylene diamine (MPD) monomers. Chlorine modification using NaOCl solution was applied to two TFC membranes (denoted as XBPSH-TFC-Cl and XPBO-TFC-Cl, respectively) to improve water permeability (A) of the polyamide selective layer, while maintaining decent salt rejection values (R). As a result, the highly efficient XPBO-TFC-Cl achieved a peak power density of 26.6 W.m(-2) at 21 bar using 1 M NaClaq and deionized (D.I.) water as draw and feed solutions, respectively. According to the modeling results, XPBO-TFC-Cl was less affected by the adverse phenomena (such as concentration polarization and reverse salt permeation), and showed lower performance reduction for various feed sources compared to XBPSH-TFC-Cl. These results demonstrate the potential of the next generation TFC membranes, which are commonly used for power generation and liquid separation.

Polymers are promising materials for gas separation membranes. However, the trade-off relationship between gas permeability and selectivity remains an obstacle for achieving polymer membranes that exhibit high gas permeation with desirable separation efficiency. Improving polymer microporosity is of interest in gas separation membranes to enhance gas transport behavior. Polymer modifications by (a) incorporating intrinsically microporous units and/or (b) increasing chain rigidity can enhance microporosity in conventional polymer membrane materials such as polyimides. These strategies are adopted for new classes of microporous polymers, thermally rearranged (TR) polymers, and polymers with intrinsic microporosity (PIMs), to maximize gas transport properties. Their outstanding gas separation performances have redefined the traditional trade-off lines. This review aims to explore the advances in microporous polymers for gas separation applications. The approaches on TR polymers and PIMs to enhance their microporosity are listed, and their developments are evaluated in the context of revisiting performance limits for industrially relevant gas separation applications.

The structural uniqueness of covalent organic frameworks (COFs) has brought these new materials great potential for advanced applications. One of the key aspects yet to be developed is how to improve the robustness of covalently linked reticular frameworks. In order to make the best use of pi-conjugated structures, we develop herein a killing two birds with one stone strategy and construct a series of ultrastable benzoxazole-based COFs (denoted as LZU-190, LZU-191, and LZU-192) as metal-free photocatalysts. Benefiting from the formation of benzoxazole rings through reversible/irreversible cascade reactions, the synthesized COFs exhibit permanent stability in the presence of strong acid (9 M HC1), strong base (9 M NaOH), and sunlight. Meanwhile, reticulation of the benzoxazole moiety into the Jr-conjugated COF frameworks decreases the optical band gap and therefore increases the capability for visible-light absorption. As a result, the excellent photoactivity and unprecedented recydability of LZU-190 (for at least 20 catalytic runs, each with a product yield of 99%) have been illustrated in the visible-light-driven oxidative hydroxylation of arylboronic acids to phenols. This contribution represents the first report on the photocatalytic application of benzoxazole-based structures, which not only sheds new light on the exploration of robust organophotocatalysts from small molecules to extended frameworks but also offers in-depth understanding of the structure activity relationship toward practical applications of COF materials.

A new application of silicon Grignard reagents in C(sp(3))-Si bond formation is reported. With the aid of BF3 center dot OEt2, these silicon nucleophiles add across alkenes activated by various azaaryl groups under copper catalysis. An enantioselective version employing benzoxazole-activated alkenes as substrates and a CuI-josiphos complex as catalyst has been developed, forming the C(sp3)-Si bond with good to high enantiomeric ratios (up to 97:3). The method expands the toolbox for conjugate addition type C(sp(3))-Si bond formation.

We embarked on a structural optimization campaign aimed at the discovery of novel anti-angiogenesis agents with previously reported imidazole kinase inhibitors as a lead compound. A library of 29 compounds was synthesized. Several title compounds exhibited selective inhibitory activities against vascular endothelial growth factor receptor 2 (VEGFR-2) over epidermal growth factor receptor (EGFR) kinase; these compounds also displayed selective and potent antiproliferative activity against three cancer cell lines. The newly synthesized compounds were evaluated for anti-angiogenesis activity by chick chorioallantoic membrane (CAM) assay. Among them, 1-(2-(2-chlorophenyl)benzo[d]oxazol-5-yl)-3-(4-(trifluoromethoxy)phenyl)urea (compound 5 n) showed the most potent anti-angiogenesis capacity, efficient cytotoxic activities (in vitro against human umbilical vein endothelial cells (HUVEC), H1975, A549, and HeLa cell lines, with respective IC50 values of 8.46, 1.40, 7.61, and 0.28 mu m), and an acceptable level of VEGFR-2 kinase inhibition (IC50=0.25 mu m). Molecular docking analysis revealed 5 n to be a type II inhibitor of VEGFR-2 kinase. In general, these results indicate that these 6-arylurea-2-arylbenzoxazole/benzimidazole derivatives are promising inhibitors of VEGFR-2 kinase for potential development into anti-angiogenesis drugs.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 273-53-0. SDS of cas: 273-53-0.

Detection and visualization of latent fingermarks are research areas that have been extensively explored over the years, mainly in the search for new methods and to improve existing fingermark developers. The aim of the present study was to propose new fingermark developers in an attempt to improve existing methods, especially regarding characteristics such as sensitivity, selectivity and ease of visualization on various substrates. In addition, we looked for developers that are cheaper, more environmentally friendly and less harmful to the health of those who handle them often. For this, the formulation of the proposed fluorescent developers was based on starch, a natural and high abundant polymer matrix. The small amount of organic dye incorporated into this matrix considerably reduces any risk of inherent toxicity. The high photophysical stability of the novel developer due to the use of embedded dyes that exhibit the excited-state infra-molecular proton transfer (ESIPT) mechanism and a high Stokes shift confer important and relevant optical properties. The influence of fingermark age and sequential deposition were studied. The results of the present study show that these novel developers are efficient and promising, especially for detecting fresh and non-fresh fingermarks on porous and non-porous substrates. Furthermore, the high photophysical stability of these fluorescent microparticles allow for preserving developed prints for a long time without degradation (important for the chain of custody).
