Synthesis and characterization of amino glucose-functionalized silica-coated NiFe2O4 nanoparticles: A heterogeneous, new and magnetically separable catalyst for the solvent-free synthesis of 2,4,5-trisubstituted imidazoles, benzo[d]imidazoles, benzo[d]oxazoles and azo-linked benzo[d]oxazoles

Amino glucose-functionalized silica-coated NiFe2O4 nanoparticles (NiFe2O4@SiO2@amino glucose) were chemically synthesized and characterized by transmission electron microscope (TEM), X-ray diffraction (XRD), thermal gravimetric analysis (TGA), energy dispersive X-ray analysis (EDX), vibrating sample magnetometer (VSM), Zetasizer and Fourier transform infrared spectroscopy (FT-IR) instruments. NiFe2O4@SiO2@amino glucose supply an environmentally friendly procedure for the synthesis of 2,4,5-trisubstituted imidazoles through one-pot multicomponent condensation of benzil or benzoin, ammonium acetate with aryl aldehydes and for the synthesis of benzoxazoles using condensation reaction of 2-aminophenol with aryl aldehydes under solvent free condition. In the other study, this synthesized magnetically reusable catalyst was introduced as a new avenue for the synthesis of benzofdlimidazoles using the reaction between aryl aldehydes and 1,2-diaminobenzene. These compounds were obtained in high yields and short reaction times. The catalyst could be easily recovered and reused for five cycles with almost consistent activity. Synthesized compounds were characterized by their physical constant, comparison with authentic samples, FT-IR, H-1 NMR, C-13 NMR spectroscopy and elemental analysis. (C) 2018 Elsevier B.V.

Regulatory Dendritic Cells Induced by K313 Display Anti-Inflammatory Properties and Ameliorate Experimental Autoimmune Encephalitis in Mice

As a GSK-3 beta inhibitor reported by our group, K313 is a novel benzoxazole derivative and displays anti-inflammatory properties in RAW264.7 macrophages without cytotoxicity. The activity of GSK-3 beta affects the differentiation and maturation of bone marrow-derived dendritic cells (DCs). This study aims to investigate whether K313 can be used to induce regulatory/tolerogenic dendritic cells (DCregs), and the therapeutic effects of DCregs induced by K313 in the autoimmune model of experimental autoimmune encephalitis (EAE). The results show that compared with LPS stimulated mature DCs, K313-treated bone marrow-derived DCs display obvious tolerogenic characteristics with decreased expression of co-stimulatory molecules, downregulated secretions of pro-inflammatory cytokines and unregulated secretion of anti-inflammatory cytokine IL-10. The above characteristics conform to the typical phenotypes of DCregs. Moreover, K313-modified DCregs inhibit antigen-specific T cell responses in vitro. Furthermore, by adoptive transfer, K313 modified DCregs to the EAE mice, and the development of disease was ameliorated to some extent. In addition, treatment with K313-modified DCregs also significantly reduced the percentages of splenetic Th1 and Th17 cells and increased the percentage of regulatory T cells in EAE mice. In conclusion, K313-modified DCregs show anti-inflammatory properties in vitro and have a significant positive effect on the EAE disease in vivo. Our data indicate that K313-induced DCregs pulsed with auto-antigen might have potential use as a therapeutic approach for autoimmune inflammation of the central nervous system.

Processable poly(benzoxazole imide)s derived from asymmetric benzoxazole diamines containing 4-phenoxy aniline: synthesis, properties and the isomeric effect

Two asymmetric diamine monomers, incorporating both aryl ether and non-linear benzoxazole groups, namely 5-amino-2-(4-(4-aminophenoxy)phenyl)benzoxazole (p-BOODA) and 5-amino-2-(3-(4-aminophenoxy)phenyl)benzoxazole (m-BOODA), were designed and synthesized. Two novel series of poly(benzoxazole imide)s (PBOIs), PI-3(a-e) and PI-4(a-e), were prepared via thermal imidization of commercial tetracarboxylic dianhydrides with diamines p-BOODA and m-BOODA, respectively. The effects of chain isomerism on molecular packing and the physical properties of PBOIs are investigated. These PBOIs showed excellent mechanical properties with tensile strengths of 106-168 MPa, tensile moduli of 2.7-5.5 GPa and elongations at break of 4.4-9.3%; in addition, they exhibited good thermal stability (T-5% = 488-570 degrees C) and high glass transition temperatures (T(g)s) up to 333 degrees C. Moreover, BTDA (3,3,4,4-benzophenone tetracarboxylic dianhydride) derived PBOIs, PI-3b and PI-4b, showed crystalline transition in spite of bent groups and the asymmetric chain structure. The incorporation of the asymmetric benzoxazole structure with flexible ether connecting groups improved the solubility of the PBOI system. Furthermore, the controlled molecular weight (M-w) polymer PI-4e-PA derived from m-BOODA demonstrated excellent solution and melt processability with the lowest complex viscosity of 44 Pa s at 380 degrees C.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 540-36-3 is helpful to your research. Safety of 1,4-Difluorobenzene.

Thiosemicarbazonate complexes with affinity for amyloid-beta fibers: synthesis, characterization and biological studies

Aim: Obtain radioimages of amyloid-beta fibers using Tc-99m-complexes. Methodology: Tridentate thiosemicarbazone and thiocarbonohydrazone ligands containing fragments (stilbene, azobenzene, benzothiazole or benzoxazole) with affinity for amyloid-beta fibers and its Re(I) complexes have been prepared. The molecular structures of several ligands and complexes were determined by x-ray diffraction. Binding affinity studies toward A beta 1- 42 fibers were performed for the ligands and Re(I) complexes. The ability of formation of some Tc-99m(I) complexes, their biodistribution and in vivo stability have been established. Results & conclusion: Complexes of stilbene and benzothiazole thiosemicarbazonates show similar affinity for amyloid-beta fibers to the free ligand. These Tc-99m complexes present a reasonable in vivo stability and a low capability to cross the blood-brain barrier although not sufficient to brain amyloid imaging.

Effects of ionic liquid doping on gas transport properties of thermally rearranged poly(hydroxyimide)s

In this study we present a novel and simple approach to improve the gas separation performance of the thermally rearranged membranes, which involves doping the polyimide precursors (HPI) with ionic liquid (IL), and carrying out its degradation along with the conversion process to polybenzoxazole (PBO) in order to facilitate the formation of larger and /or more numerous free volumes. A series of aromatic (co)poly(hydroxyimide)s based on 6FDA and HAB/4MPD diamines in different molar ratios, as well as BPADA-HAB poly(hydroxyimide) were synthesized as the precursors to be doped with IL and thermally rearranged to PBO. The structural modifications of the precursor backbone were applied to study the impact of IL on the physical properties, thermal conversion process, as well as gas transport properties of the doped polymers with different chain rigidities. The pure and IL doped (co)polyimides and their thermally rearranged counterparts were characterized by WAXD, DSC, TGA, tensile tests, and PALS, and examined in pure gas permeation experiments. TR conversion temperature was considerably reduced by IL doping (e.g. by 126 degrees C). This effect depended on the precursor chemical structure and the IL content. After thermal rearrangement of the IL doped HPIs, the membrane permeability to gases increased significantly compared to the un-doped analogues (e.g. 2 fold increase for O-2 permeability). The permeability increase was larger for the higher IL content and the precursor chain rigidity. This was accompanied by a relatively small loss in selectivity leading to the performance shift towards the 2008 upper bound. The differences in permeability among the samples correlated with the free volume size from PALS. In particular, a very good correlation was obtained (r(2) = 0.958), when the data fitted to the Cohen-Turnbull model concerned only PBO samples with low cohesive energy density. Further studies on HPIs doped with IL with lower degradation temperatures are suggested to mitigate polymer degradation and explore this new method for the design of improved gas separation membrane materials.

Synthesis and biological evaluation of some 1,3-benzoxazol-2(3H)-one hybrid molecules as potential antioxidant and urease inhibitors

A new series of 1,3-benzoxazol-2(3H)-one hybrid compounds, including coumarin, isatin 1,3,4-triazole and 1,3,4-thiadiazole moieties, were synthesized and biologically evaluated for their antioxidant capacities and anti-urease properties. The synthesized benzoxazole-coumarin (6a-e) and benzoxazole-isatin (10a-c) hybrids showed remarkable urease inhibitory activities with IC50(mu M), ranging from 0.0306 +/- 0.0030 to 0.0402 +/- 0.0030, while IC(50)of standard thiourea is 0.5027 +/- 0.0293. The synthesized benzoxazole-triazole (8a-c) and benzoxazole-thiadiazole (9a-c) hybrids showed similar urease inhibitory activities with IC50(mu M), ranging from 0.3861 +/- 0.0379 to 0.5126 +/- 0.0345. The antioxidant activity of the synthesized compounds was evaluated for their antioxidant activities, such as reducing power and ABTS (2,2 ‘-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt) radical scavenging. The results of ABTS radical scavenging activities of some of the synthesized molecules showed higher activities than standard Trolox, SC50(mu M) = 213.04 +/- 18.12. One benzoxazole-coumarin (6f), two benzoxazole-isothiocyanate (7b, 7c), and two benzoxazole-triazole (8b, 8c) derivatives showed higher activities (SC50(mu M) values, 82.07 +/- 10.34, 120.19 +/- 7.30, 104.58 +/- 10.55, 153.26 +/- 7.14, and 144.82 +/- 10.68, respectively) than standard Trolox, (SC50(mu M) = 213.04 +/- 18.12).

Enhanced, hydrophobic, fluorine-containing, thermally rearranged (TR) nanofiber membranes for desalination via membrane distillation

Though membrane distillation (MD) has been considered as a promising desalination process, it is still required to develop a desirable membrane which has high water flux and long-term stability for practical use in the MD process. In our previous work, thermally rearranged nanofiber membranes (TR-NFMs), which exhibited high water flux (80 kg m(-2) h(-1)) and salt rejection (> 99.99%) as well as outstanding long-term stability (more than 180 h), were first introduced as a promising candidate for MD applications. However, nascent TR-NFM is susceptible to fluctuations in operating conditions due to insufficient liquid entry pressure with water (LEPw). In continuation of our enhanced hydrophobic TR-NFM study, we develop fluorine-containing thermally-rearranged nanofiber membranes (F-TR-NFMs) for MD applications for the first time. F-TR-NFMs showed enhanced hydrophobic properties such as high water contact angle (143 degrees), high LEPw (1.3 bar), and high effective evaporation area (EEA) due to the introduction of fluorine atoms in the backbone of the TR membrane. As the result, the developed F-TR-NFMs exhibited outstanding MD performance (114.8 kg m(-2) h(-1) of water flux and > 99.99% of salt rejection at feed and permeate temperatures of 80 degrees C and 20 degrees C, respectively) and excellent energy efficiency (52.1% at feed and permeate temperatures of 50 degrees C and 20 degrees C, respectively). The long-term stability of F-TR-NFM is also investigated over more than 250 h of operation time.

Benzoxazole derivatives suppress lipopolysaccharide-induced mast cell activation

Mast cells are central regulators of allergic inflammation that function by releasing various proallergic inflammatory mediators, including histamine, eicosanoids and proinflammatory cytokines. Occasionally, bacterial infections may initiate or worsen allergic inflammation. A number of studies have indicated that activation of lipoxygenase in mast cells positive regulates allergic inflammatory responses by generating leukotrienes and proinflammatory cytokines. In the present study, the effects of benzoxazole derivatives on the lipopolysaccharide (LPS)-induced expression of proinflammatory cytokines, production of histamine and surface expression of co-stimulatory molecules on bone marrow-derived mast cells (BMMCs) were studied. The benzoxazole derivatives significantly reduced the expression of interleukin (IL)-1 beta, IL-6, IL-13, tumor necrosis factor-alpha, perilipin (PLIN) 2, and PLIN3 in BMMCs treated with LPS. Furthermore, histamine production was suppressed in BMMCs treated with LPS, or treated with phorbol-12-myristate-13-acetate/ionomycin. Benzoxazole derivatives marginally affected the surface expression of cluster of differentiation (CD)80 and CD86 on BMMCs in the presence of LPS, although LPS alone did not increase the expression of those proteins. Therefore, benzoxazole derivatives inhibited the secretion of proinflammatory cytokines in mast cells and may be potential candidate anti-allergic agents to suppress mast cell activation.

Three new mixed-ligand copper(II) complexes containing glycyl-l-valine and N,N-aromatic heterocyclic compounds: Synthesis, characterization, DNA interaction, cytotoxicity and antimicrobial activity

Three novel copper(II) complexes, [Cu(Gly-l-Val)(HPBM)(H2O)]ClO4H2O (1), [Cu(Gly-l-Val)(TBZ)(H2O)]ClO4 (2) and [Cu(Gly-l-Val)(PBO)(H2O)]ClO4 (3) (Gly-l-Val=glycyl-l-valine anion, HPBM=5-methyl-2-(2-pyridyl)benzimidazole, TBZ=2-(4-thiazolyl)benzimidazole, PBO=2-(2-pyridyl)benzoxazole), have been prepared and characterized with elemental analyses, conductivity measurements as well as various spectroscopic techniques. The interactions of these copper complexes with calf thymus DNA were explored using UV-visible, fluorescence, circular dichroism, thermal denaturation, viscosity and docking analyses methods. The experimental results showed that all three complexes could bind to DNA via an intercalative mode. Moreover, the cytotoxic effects were evaluated using the MTT method, and the antimicrobial activity of these complexes was tested against Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. The results showed that the activities are consistent with their DNA binding abilities, following the order of 1 > 2 > 3.

Fluorescent phenoxy benzoxazole complexes of zirconium and hafnium: synthesis, structure and photo-physical behaviour

A series of ten heteroleptic and homoleptic mononuclear Zr(iv) and Hf(iv) complexes bearing differently substituted phenoxy-benzoxazole ligands was synthesised. The complexes were characterised by H-1 and C-13{H-1} NMR spectroscopy as well as by elemental analyses and X-ray diffraction experiments. The molecular structures show octahedral or tetragonal-antiprismatic coordination motifs at the metal atom. The crystal packing patterns depend on the substitution of the ligands. The intermolecular interactions in the solid state are governed by weak – interactions, and are also dependent on the ligand structure. Photo-physical investigations reveal that all ten complexes show a ligand-centered fluorescence with emission maxima in the blue region of the electromagnetic spectrum.
