A theoretical study on excited state proton transfer in 2-(2 ‘-dihydroxyphenyl) benzoxazole

This research investigates the dynamic excited state process for a novel system 2-(2-dihydroxyphenyl) benzoxazole (DHBO) for excited state proton transfer (ESPT) process based on density functional theory (DFT) and time-dependent DFT (TDDFT) methods. Because 2 intramolecular hydrogen bonds (O-1?H2N3 and O-4?H5O6) in DHBO molecules may trigger proton transfer process in the S-1 state, we focus on these 2 hydrogen bonds. Our results show that only the O-1?H2N3 bond has obvious changes in both bond length and bond angle upon photoexcitation. Charge redistribution also confirms that hydrogen bond wire (O-1?H2N3) is the best way to achieve the ESPT process in the S-1 state. Considering the ESPT mechanism, our theoretical potential energy curves of DHBO indicate that only the excited state single-proton transfer process occurs via O-1?H2N3 rather than O-4?H5O6. We believe that our work not only clarifies the excited state dynamical behavior of DHBO but also promotes the investigations about ESPT reactions in intramolecular or intermolecular hydrogen bonded chemical systems.

SeO2 Mediated Synthesis of Selected Heterocycles by Oxidative C-C Bond Cleavage of AcetophenoneDerivatives

An interestingcyclization reactions of aryl ketones with 2-amino aniline derivatives under SeO2 (oxidant) are described for the synthesis of benzoxazole, benzothiazole, benzimidazole and quinazolinone through the C-C cleavage of acetophenone. The reaction likely involves sequential C-N, C-O and C-S bond formation followed by C(CO)-C(alkyl) bond cleavage. Various substituted fused heterocycles are obtained in good to excellent (gram scale) yields in a single step from readily available acetophenones.

Liquid-crystalline behavior and thermal conductivity of vinyl polymers containing benzoxazole side groups

A series of methacrylamides containing benzoxazole (BO) mesogenic side groups and different lengths of alkyl units was synthesized in this study. A methacrylamide containing the n-dodecyl group was selected as a suitable monomer to obtain beneficial thermally conductive polymeric materials because of its sufficient solubility in toluene in the subsequent radical polymerization and because of its liquid crystallinity. This methacrylamide led to a highly soluble polymer with film-forming ability. The BO-containing polymethacrylamide also exhibited liquid-crystalline (LC) behavior during the heating and cooling processes. The cast film was kept at a slightly lower temperature than the clearing temperature and quenched to room temperature. This procedure afforded a film maintaining optical anisotropy at room temperature, implying that a frozen LC structure is maintained at room temperature. The quenched film also resulted in a significantly enhanced thermal conductivity (lambda = 0.60 W m(-1) K-1) without the aid of fillers and external fields, unlike the as-cast counterpart without optical anisotropy. A polyacrylate containing a flexible long alkylene (C-6) spacer between the main chains and a BO-containing mesogenic side group was also investigated. The polyacrylate exhibited LC behavior during the heating and cooling processes over wide ranges. The polyacrylate film quenched from an established temperature, which contains a frozen LC structure, also exhibited a significantly enhanced lambda value (0.63 W m(-1) K-1) without fillers and external fields. Thus, the BO-containing vinyl polymers studied in this work are promising candidates for novel heat-releasing materials. (c) 2020 Society of Chemical Industry

QSAR Modeling and Drug-Likeness Screening for Antioxidant Activity of Benzofuran Derivatives

In order to explore the relationship between the antioxidant activity and structure of fifteen benzofuran derivatives, we carried out a QSAR study using multiple linear regression (MLR) and artificial neural network (ANN) methods. Six descriptors were used as input data (molar weight, surface area, octanol-water partition coefficient, hydration energy, highest occupied molecular orbital energy and lowest unoccupied molecular orbital energy). The electronic properties were derived at the B3LYP/6-31 G (d,p) level. Benchmarks on furan and benzofuran subunits and their comparison to the experiment showed that this level of theory is good enough. The output data correspond to the antioxidant activity as given by IC50. The predicted properties are in agreement with experimental values. Our study shows that 80% of studied molecules are in accordance with the Lipinski and Veber rules and reach the optimal lipophilicity indices. In addition, statistical analysis reveals that ANN technique with (6-2-1) architecture is more significant than MLR model. (C) 2019 Elsevier B.V. All rights reserved.

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.

High-performance poly( benzoxazole/benzimidazole) bio-based plastics with ultra-low dielectric constant from 3-amino-4-hydroxybenzoic acid

High-performance bio-based plastics can make a major contribution to environmental sustainability. A series of high-performance poly(2,5-benzoxazole-co-2,5-benzimidazole)s (PBO-co-PBI) bio-based plastic films, were developed using the aromatic biomolecule 3-amino-4-hydroxybenzoic acid and the commercial product 3,4-diaminobenzoic acid. The partially bio-based PBO-co-PBI films exhibit higher thermal and mechanical performance than conventional bio-based polymers such as polyamide 11 or poly(lactic acid). The robust PBO-co-PBI films exhibit lower dielectric constants (e(r)) than conventional high-performance aromatic polymers, attaining the value comparable to those of polyethylene or polypropylene.
