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.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

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.

Simultaneously achieving excellent mechanical properties and superior gas separation performance remains a great challenge for thermally rearranged polymers when applied as the membrane materials in large scale gas separation applications. Herein, different heteroaromatic non-TR-able codiamines containing benzimidazole/benzoxazole structures were incorporated into ortho-hydroxyl functionalized polyimide backbones, which were subsequently transformed into the poly(benzoxazole-co-polyimide) copolymers by thermal rearrangement (TR). In all cases, the solid-state TR reaction induces the increased preferential intersegmental distances (d-spacing) and fractional free volumes of polymer chains, favorable for the gas permeation. While, the pi-pi stacking distance exhibits opposite variation tendencies for benzimidazole-based and benzoxazole-based TR-PBOI membranes, which is demonstrated to make a significant effect on the gas selectivity. These TR-PBOI membranes thermally treated at 420 degrees C for 1 h exhibit higher tensile properties in relative to most of previously reported TR-PBOI membranes with the tensile strength of 97-118 MPa and initial modulus of 2.0-2.4 GPa. Moreover, incorporating heteroaromatic non-TR-able codiamines endows the resultant TR-PBOI membranes with excellent gas separation properties for the CO2/CH4 gas pairs with the CO2 permeability and CO2/CH4 ideal selectivity values exceeding the 1991 upper bound and close to 2008 upper bound. We anticipate this facile method will facilitate the large-scale preparation and application of TR membranes for gas separation.

The Pd(OAc)(2)/PhI(OAc)(2) catalyst system promotes the highly regioselective dehydrogenative methoxylation of a C(sp(3))-H bond adjacent to benzoxazole and benzothiazole rings. The title transformation constitutes the first example of a Pd-catalyzed C(sp(3))-H activating methoxylation at the proximal-selective a-position with regard to a directing auxiliary and provides expedient access to an important class of azole-decorated methyl ethers (up to 90% isolated yield). The synthetic practicality of the methodology was demonstrated by achieving a-methoxyacetic acids via the elimination of the benzoxazole auxiliaries and by obtaining the precursor of an O-methylated Breslow intermediate.

Risperidone (RSP) is an atypical antipsychotic drug which acts as a potent antagonist of serotonin-2 (5TH2) and dopamine-2 (D2) receptors in the brain; it is used to treat schizophrenia, behavioral and psychological symptoms of dementia and irritability associated with autism. It is a poorly water soluble benzoxazole derivative with high lipophilicity. Supramolecular adducts between drug substance and two methylated beta-cyclodextrins, namely heptakis(2,6-di-O-methyl)-beta-cyclodextrin (DM-beta-CD) and heptakis(2,3,6-tri-O-methyl)-beta-cyclodextrin (TM-beta-CD) were obtained in order to enhance RSP solubility and improve its biopharmaceutical profile. The inclusion complexes were evaluated by means of thermoanalytical methods (TG-thermogravimetry/DTG-derivative thermogravimetry/HF-heat flow), powder X-ray diffractometry (PXRD), universal-attenuated total reflectance Fourier transform infrared (UATR-FTIR), UV spectroscopy and saturation solubility studies. Job’s method was employed for the determination of the stoichiometry of the inclusion complexes, which was found to be 2:1 for both guest-host systems. Molecular modeling studies were carried out for an in-depth characterization of the interaction between drug substance and cyclodextrins (CDs). The physicochemical properties of the supramolecular systems differ from those of RSP, demonstrating the inclusion complex formation between drug and CDs. The RSP solubility was enhanced as a result of drug encapsulation in the CDs cavity, the higher increase being obtained with DM-beta-CD as host; the guest-host system RSP/DM-beta-CD can thus be a starting point for further research in developing new formulations containing RSP, with enhanced bioavailability.

Mutations in RAS/RAF occur in large portion of malignancies and are associated with aggressive clinical behaviors and poor prognosis. Therefore, we developed a novel benzoxazole compound (KZ-001) as a highly potent and selective MEK 1/2 inhibitor. Our efforts were focused on enhancing the activity of the known MEK inhibitor AZD6244 and overcoming the shortcomings existing in current MEK inhibitors. Here we show that compound KZ-001 exhibits approximately 30-fold greater inhibition against BRAF- and KRAS-mutant tumor cells than that of AZD6244. These results were also demonstrated using in vivo xenograft models. Furthermore, pharmacokinetics (PK) analysis was performed for KZ-001, and this compound showed good orally bioavailability (28%) and exposure (AUC(0-infinity) = 337 +/- 169 ng h/mL). To determine its potential clinical application, the synergistic effect of KZ-001 with other agents was investigated both in vitro and in vivo (xenograft models). KZ-001 exhibited synergistic anti-cancer effect in combination with BRAF inhibitor vemurafenib and a microtubule-stabilizing chemotherapeutic agent docetaxel. In addition, KZ-001 inhibited the MAPK pathway like known MEK inhibitors. In summary, KZ-001, a structurally novel benzoxazole compound, was developed as a MEK inhibitor that has potential for cancer treatment.

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%.
