Aryl Ketone Mediated Photoinduced Radical Coupling for the Alkylation- of Benzazoles Employing Saturated Heterocyclic Compounds

An aryl ketone mediated synthesis of 2-alkylated benzazoles was achieved via radical coupling under photoirradiation starting from saturated heterocycles and 2-sulfonylated benzazoles, such as benzothiazoles, benzoxazole, and benzimidazole. Heterocyclic compounds, including a cyclic ether, azacycles, and tetrahydrothiophene, were applicable, and the benzazole unit was site-selectively installed at the carbon center proximal to the heteroatom. The present transformation takes place at ambient temperature under neutral reaction conditions without the aid of any metallic catalysts or reagents.

Novel SIRT1 activator MHY2233 improves glucose tolerance and reduces hepatic lipid accumulation in db/db mice

The NAD(+)- dependent deacetylase SIRT1, which is associated with the improvement of metabolic syndromes, such as type 2 diabetes, is a well-known longevity-related gene. Several in vitro and in vivo studies have shown the known protective effects of SIRT1 activators, such as resveratrol and SRT1720, on diabetes-or obesity-induced fatty liver and insulin resistance. Here, we newly synthesized 18 benzoxazole hydrochloride derivatives based on the structure of resveratrol and SRT1720. We performed an in vitro SIRT1 activity assay to identify the strongest SIRT1 activator. The assay confirmed MHY2233 to be the strongest SIRT1 activator (1.5-fold more potent than resveratrol), and docking simulation showed that the binding affinity of MHY2233 was higher than that of resveratrol and SRT1720. To investigate its beneficial effects, db/db mice were orally administered MHY2233 for 1 month, and various metabolic parameters were assessed in the serum and liver tissues. MHY2233 markedly ameliorated insulin signaling without affecting body weight in db/db mice. In particular, the mRNA expression of lipogenic genes, such as acetyl CoA carboxylase, fatty acid synthase, and sterol regulatory element-binding protein, which increased in db/db mice, decreased following oral treatment with MHY2233. In conclusion, the novel SIRT1 activator MHY2233 reduced lipid accumulation and improved insulin resistance. This finding may contribute toward therapeutic approaches for fatty liver disease and glucose tolerance. (C) 2018 The Authors. Published by Elsevier Ltd.

Medium viscosity effect on fluorescent properties of Sn(IV)-tetra(4-sulfonatophenyl)porphyrin complexes in buffer solutions

Supramolecular triads consisting of hydrophilic Sn(IV)-tetra(4-sulfophenyl)-porphyrin and two axial guests such as propylphenol, tyrosine, and 2-(2-hydroxyphenyl)-benzoxazole were synthesized. The structures of synthesized complexes were identified by experimental spectroscopic and quantum-chemical simulation methods, and their fluorescent properties were studied in various viscosity media (mixed phosphate buffer-glycerin solvents of different composition). The effect of axial ligand structure on the fluorescent properties of these triads (due to the hydrogen bonding or pi-pi stacking between the components of host-guest systems) is discussed. The potential use of synthesized complexes as environmental probes of local viscosity is proposed. (C) 2019 Elsevier B.V. All rights reserved.

Benzoxazole and dioxolane substituted benzimidazole-based N-heterocyclic carbene-silver( I) complexes: Synthesis, structural characterization and in vitro antimicrobial activity

A novel series of 1,3-benzoxazole and 1,3-dioxolane substituted benzimidazole-based N-heterocyclic carbene (NHC) precursors (6a-b and 11a-b) and their corresponding NHC-silver(I) acetate (12a-b and 14a-b) and bis-NHC-silver(I) hexafluorophosphate complexes (13a-b and 15a-b) were synthesized and characterized by H-1 NMR, C-13 NMR, ATR-IR spectroscopic methods and elemental analysis techniques. Also, the molecular structure of benzimidazolium salt (6a) and bis-NHC-silver(I) hexafluorophosphate complex (13b) were unambiguously established by single crystal X-ray diffraction analysis. Fascinatingly, bis-NHC-silver(I) hexafluorophosphate complex (13b) was revealed to be dinuclear in nature. All the azolium salts (6a-b and 11a-b) as well as the corresponding silver(I) complexes (12a-b, 13a-b, 14a-b and 15a-b) were evaluated for their antimicrobial potential against Gram positive (Staphylococcus aureus), and a set of Gram negative (Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa) bacterial strains and two fungi, Candida albicans and Cryptococcus neoformans. Antimicrobial studies revealed the comparable activities of benzimidazolium salts (6a-b and 11a-b) and the silver(I) complexes (12a-b, 13a-b and 15a-b). Whereas, the 1,3-dioxolane substituted benzimidazole-based silver(I) acetate complexes (14a-b) demonstrated excellent potentials with both bacterial and fungal growth inhibition above 95%.

Synthesis, structure, luminescence and electrochemical and antioxidant properties of anion-controlled silver(I) complexes with 2,2 ‘-(1,4-butanediyl)bis-1,3-benzoxazole

To explore the influence of various anions on the self-assembly and properties of silver complexes, reactions of anions of silver salts with 2,2 ‘-(1,4-butanediyl)bis-1,3-benzoxazole (BBO) afforded four complexes, formulated as [Ag-2(BBO)(2)(p-toluenesulfonate)(2)] (1), {[Ag(BBO)(picrate)]}(infinity) (2), {[Ag(BBO)(1/2)(o-coumarate)]center dot DMF}(infinity) (3) and {[Ag-2(BBO)(3)](PF6)(2)}(infinity) (4). These complexes were characterized using elemental analysis, infrared spectroscopy and single-crystal X-ray diffraction. The crystal analysis results show that under the influence of coordination modes and steric hindrance of anions, the complexes exhibited binuclear (1), one-dimensional polymeric (2 and 3) and two-dimensional polymeric (4) structures. Compared with the BBO ligand, only complex 1 has a new emission peak at 428 nm, which is attributed to ligand-metal charge transfer. The emission peaks of complexes 2-4 are similar to those of the BBO ligand, which can be due to pi-pi* and n-pi* transitions. These results indicate that anions can modulate the structures and luminescent properties of silver complexes. Moreover, cyclic voltammograms of 1-4 indicated an irreversible Ag+/Ag couple with the order of reversibility being 2 > 1 > 4 > 3. In vitro antioxidant experiments showed that complex 3 has significant antioxidant activity against superoxide and hydroxyl radicals.

Synthesis and biological activity evaluation of azacycloheptane sulfonamide derivatives as potential orexin receptor antagonists

As the orexin signaling system is crucial for the regulation of the sleep/wake cycle, inhibitors of orexin-1 and orexin-2 receptors are of significant interest in the treatment of insomnia. Herein, a series of novel azacycloheptane sulfonamide derivatives were designed and synthesized, and all the compounds were evaluated as potential orexin receptor inhibitors by FLIPR Tetra calcium assay. A majority of the tested azacycloheptane sulfonamide derivatives showed OX1R and OX2R inhibitory activity. Chloro-substituted derivatives functionalized at the C5 or C6 position of the benzoxazole group exhibited better inhibitory activity for OX1R and OX2R than unsubstituted derivatives functionalized at C5 or C6. In addition, phenyl group modification had positive effects on the inhibitory activities, and an electron-withdrawing fluorine group at theorthoormetaposition of the phenyl ring improved the OX2R inhibitory activity of the derivatives. This suggests that azacycloheptane sulfonamide derivatives are promising scaffolds for the development of OX1R and OX2R antagonists.

Effects of the functional groups amino and nitro on the reactivity of benzoxazoles and comparison with homologous benzothiazoles

The energetic study of 2-aminobenzoxazole (ABO) and 2-methyl-6-nitrobenzoxazole (MNBO) has been developed using experimental and computational tools. The enthalpies of combustion, of fusion, and of sublimation of these compounds were measured by static-bomb combustion calorimetry, differential scanning calorimetry, and Calvet microcalorimetry drop-technique and/or the Knudsen-effusion method. Additionally, we calculated the gas-phase standard molar enthalpies of formation of these compounds, as well as of 2-methyl-6-nitrobenzothiazole (MNBT), through high level ab initio calculations, at the G3(MP2)//B3LYP level of theory. Furthermore, the energetic effects associated with the presence of the amino and nitro groups on the core of benzoxazole or benzothiazole molecules were also evaluated, as well as stabilizing electronic interactions occurring in the molecules. The latter were investigated through Natural Bonding Orbital (NBO) of the corresponding wave functions. Finally, the thermodynamic stability of the titled compounds was evaluated and a comparison with their sulfur heteroanalogs was achieved. In the gaseous phase, the oxygen derivatives exhibit the lowest tendency to decompose into their constituent elements at standard conditions.

Transition-Metal Acetate-Promoted Intramolecular Nitrene Insertion to Vinylogous Carbonates for Divergent Synthesis of Azirinobenzoxazoles and Benzoxazines

Synthesis and isolation of highly unstable azirinobenzoxazole and benzoxazines in a chemodivergent fashion from aryl azido vinylogous carbonates by simple change in transition metal acetate is described. Thermal or rhodium(II) acetate-mediated decomposition of these azides gave dihydroazirino benzoxazole. Their nickel(II) acetate-promoted reaction gave 4-dihydro-2H-benzoxazines, whereas copper(II) acetate led to the corresponding oxidized imine derivatives. Benzaoxazine derivative could be kinetically resolved using a proline-catalyzed Mannich reaction. The benzoxazines were rapidly elaborated to angularly fused tetracyclic systems and coumarin-fused derivatives in a one pot fashion.
