Unassymetric bis[2-(2′-hydroxyphenylbenzoxole)] bis(HBO) derivatives with a DPA functionality for zinc binding have been developed with an efficient synthetic route, using the retrosynthetic analysis. Comparison of bis(HBO) derivatives with different substitution patterns allows us to verify and optimize their unique fluorescence properties. Upon binding zinc cation, bis(HBO) derivatives give a large fluorescence turn-on in both visible (lambda(em) approximate to 536 nm) and near-infrared (NIR) window (lambda(em) approximate to 746 nm). The probes are readily excitable by a 488 nm laser, making this series of compounds a suitable imaging tool for in vitro and in vivo study on a confocal microscope. The application of zinc binding-induced fluorescence turn-on is successfully demonstrated in cellular environments and thrombus imaging.

The biological activities of aminoguanidine (GNH(2)) and its derivatives have been extensively studied due to their properties as radical scavengers and antioxidants. Some of their biological activities may result from their binding to various metals present in biological systems. However, the reactivity of coordinated aminoguanidines has not been investigated. We report herein the synthesis, structure and reactivity of a novel osmium(iii) complex bearing the parent aminoguanidine, mer-[Os{NHC(NH2)(NHNH2)}(L)(CN)(3)](-) (OsGNH(2), HL = 2-(2-hydroxyphenyl)benzoxazole). The antioxidant properties of OsGNH(2) have been investigated by reactions with various oxidants, including O-2, H2O2, m-chloroperbenzoic acid (m-CPBA) and Ce(iv). Various osmium products are produced, which depend on the type of oxidant used. OsGNH(2) is readily oxidized by O-2 or H2O2 under ambient conditions to afford an osmium(iii) formamidine complex, [Os-III(NH2CNH)(L)(CN)(3)](-) (OsFA, FA = formamidine). With m-CPBA, the nitrosyl complex, mer-[Os(NO)(L)(CN)(3)](-) (OsNO), is formed instead. On the other hand, the nitrido complex mer-[Os(N)(L)(CN)(3)](-) (OsN) is produced when the one-electron oxidant (NH4)(2)[Ce-IV(NO3)(6)] (Ce(iv)) is employed. The molecular structures of OsGNH(2) and OsFA have been determined by X-ray crystallography. The oxidation of OsGNH(2) to OsFA by O-2 or H2O2 is proposed to go through initial dehydrogenation to give a diazoamidine intermediate. In the oxidation by m-CPBA and Ce(iv), it is proposed that the initially formed OsFA is further oxidized to OsNO and OsN, respectively, via osmium(iii) hydrogen cyanamido and osmium(iv) cyanoimido intermediates.

Expanding the chemical space: Discovery of new anticancer3-arylbenzofuranderivatives

A new chemical space was generated via C-2-functionalization of 3-arylbenzofurans. Mannich reaction of 3-arylbenzofurans with secondary amines and formaldehyde allowed for installation of aminomethyl unit at C(2)position of benzofurans. A formyl group at C(2)site introduced as a result of Vilsmeier-Haack formylation of 3-arylbenzofurans was employed as a reacting partner for three-component Kabachnik-Fields reaction with various amines and triethyl phosphite to give a wide variety of aminomethylphosphonates. Furthermore, several benzo[d]oxazoles and pyrrolo[1,2-a]quinoxalines were prepared by using the formyl group. Biological screening of the synthesized compounds revealed that the benzofuran bearing a pyrrolo[1,2-a]quinoxaline moiety (5b) most potently inhibited the viability of human blood cancer cells, but not solid tumor cells. Caspase activity assay, analysis of Annexin V-positive cells, and Western blot analysis indicated that5b-induced death of human lymphoma U937 cells could result from its potential to induce the caspase-dependent apoptotic death of blood cancer cells with inhibition of ERK activation.

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

Facile synthesis of 2-benzoxazoles via CuI/2,2′-bipyridine catalyzed intramolecular C-O coupling of 2-haloanilides

Development of newer methods for the synthesis of Benzoxazoles has of greater interest due to their wide range of biological activities and pharmaceutical importance. We herein report a facile and general method for the synthesis of 2-substituted Benzoxazoles via copper catalyzed intramolecular C-O cross-coupling of 2-haloanilides. A combination of CuI (5 mol%), 2,2′-bipyridine (10 mol%), Cs2CO3 (2 equiv.) in DMF solvent with 4 angstrom molecular sieves at 140 degrees C, illustrated the scope for tuning the reactivity of 2-haloanilides toward the selective formation of a series of 2-alkyl benzoxazole derivatives in moderate to good yields. This is the first systematic study using CuI/2,2′-Bipyridine as the catalytic system for the synthesis of 2-substituted Benzoxazoles. The outcome of the reaction was found to be significantly influenced by the aromatic and amide substituents of 2-haloanilides. [GRAPHICS]
