Yusoff, Hanis Mohd;Bala Chandran, Prasana Devi;Sayuti, Fatin Amira Binti;Kan, Su-Yin;Mohd Radzi, Siti Aisha;Yong, Fu-Siong Julius;Lee, Oon Jew;Chia, Poh Wai research published 《 Highly efficient, recyclable and alternative method of synthesizing phenols from phenylboronic acids using non-endangered metal: Samarium oxide》, the research content is summarized as follows. Oxidation of phenylboronic acid to phenol is one of the important industrial processes and it is generally employed in the plastic, explosive and drug manufacturing industries. Over the past decades, numerous efficient methods have been described for the generation of phenols from phenylboronic acids in the presence of oxidant. However, these methods suffered from various limitations, including the use of expensive, toxic reagents and sophisticated protocol to synthesize the phenols. Addnl., some of these reported literatures employed endangered metals, in which mankind is facing the risk of limited supply of these elements in 20 years’ time from now. As such, a viable alternative and green method for achieving organic synthesis is highly sought after by the chemists of today. Herein, we report for the first time a facile, efficient and alternative method in the preparation of phenols from phenylboronic acids using non-endangered metal as catalyst. In all cases, all phenols were afforded in satisfactory yields (81-96%) by employing column-free method. In the recyclability study, the Sm₂O₃ catalyst was found to possess good catalytic performance, even after being reused for five consecutive times (96-91%). In addition, SEM result revealed that the morphol. of the recycled Sm₂O₃ catalyst was well preserved after five successive uses, which indicate no observable changes occurred in the recovered catalysts. As a final note, the current method is anticipated to be useful for industries manufacturing chem. intermediates as it provides an alternative method of catalysis by using a non-endangered metal in organic transformations.

Yang, Yuyuan;Zhang, Jian;Li, Xiangyang;He, Fangcheng;Wu, Rong;Hu, Deyu;Song, Baoan research published 《 Discovery of Dithioacetal Derivatives Containing Sulfonamide Moiety of Novel Antiviral Agents by TMV Coat Protein as a Potential Target》, the research content is summarized as follows. Tobacco mosaic virus coat protein (TMV CP) plays an important role in viral replication, translation, and intracellular and intercellular movements. Thus, TMV CP could be regarded as a potential target for antiviral agents. In this study, in order to find out whether dithioacetal derivatives act on the CP target, a series of dithioacetal derivatives containing sulfonamide moiety was first designed and synthesized. Bioassay results demonstrated that three of the compounds exhibited excellent activities against TMV, with half-maximal effective concentrations (EC₅₀) of the curative, protective, and inactivate activities being 183.0 ± 3.2, 252.3 ± 2.6, and 63.8 ± 1.2μg/mL, 270.6 ± 3.7, 249.7 ± 3.5, and 57.7 ± 1.4μg/mL, and 329.5 ± 1.5, 269.2 ± 3.7, and 48.1 ± 2.0μg/mL, which were higher than those for the control agents ningnanmycin (331.0 ± 2.8, 271.0 ± 2.8, and 77.4 ± 1.3μg/mL, resp.) and d2 (471.5 ± 1.4, 447.2 ± 2.1, and 91.7 ± 1.8μg/mL, resp.). Transmission electron microscopy showed that the particle morphol. of TMV was destroyed by I, and microscale thermophoresis (MST) showed that I bonded to CP with a dissociation constant (K_d) of 9.7 ± 1.7μM. Then, mol. docking and MST further illustrated that I had a weak binding affinity with the TMV mutant protein (K_d = 561.3 ± 83.2μM). Thus, we deduced that the dithioacetal derivative I may inhibit TMV activity by binding TMV CP. This work provides some new insights for the design and optimization of anti-TMV agents.

Yang, Ziqi;Ying, Yunpan;Pu, Yunchuan;Wang, Dechao;Yang, Hao;Zhao, Dan research published 《 Poly(ionic liquid)-Functionalized UiO-66-(OH)₂: Improved Interfacial Compatibility and Separation Ability in Mixed Matrix Membranes for CO₂ Separation》, the research content is summarized as follows. Incorporating porous materials into polymeric matrix to produce mixed matrix membranes (MMMs) usually offer the combined properties of each component. However, it requires efficient dispersity of porous materials in polymeric matrix and good compatibility between them. To enhance the compatibility, we report an approach by covalent grafting of poly(ionic liquid) (PIL) brushes on the surface of metal-organic framework (MOF) UiO-66-(OH)₂. Benefiting from the surface grafted PIL brushes, the as-synthesized UiO-66-(OH)₂@PIL shows an improved dispersity in solvent media and Pebax matrix due to the hydrophilicity of PIL and the formed hydrogen bonds between MOF fillers and Pebax matrix. The obtained UiO-66-(OH)₂@PIL-based MMMs manifest simultaneously increased selectivity and permeability for CO₂/N₂ separation, with the best performance at 20 wt % of loading (CO₂ permeability of 132 Barrer and CO₂/N₂ separation factor of 71). This work highlights the efficiency of MOF functionality to achieve enhanced interfacial compatibility and membrane separation performance.
