Enhanced enzymatic removal of anthracene by the mangrove soil-derived fungus, Aspergillus sydowii BPOI

The present study investigated the efficiency of Aspergillus sydowii strain bpo1 (GenBank Accession Number: MK373021) in the removal of anthracene (100 mg/L). Optimal degradation efficiency (98.7%) was observed at neutral pH, temperature (30 degrees C), biomass weight (2 g) and salinity (0.2% w/v) within 72 h. The enzyme analyses revealed 131%, 107%, and 89% induction in laccase, lignin peroxidase, and manganese peroxidase respectively during anthracene degradation. Furthermore, the degradation efficiency (99.8%) and enzyme induction were significantly enhanced with the addition of 100 mg/L of citric acid and glucose to the culture. At varying anthracene concentrations (100-500 mg/L), the degradation rate constants (k(1)) peaked with increasing concentration of anthracene while the half-life (t(1/2)) decreases with increase in anthracene concentration. Goodness of fit (R-2 = 0.976 and 0.982) was observed when the experimental data were subjected to Langmuir and Temkin models respectively which affirmed the monolayer and heterogeneous nature exhibited by A. sydwoii cells during degradation. Four distinct metabolites; anthracene-1,8,9 (2H,8aH,9aH)-trione, 2,4a-dihydronaphthalene-1,5-dione, 1,3,3a,7a-tetrahydro-2-benzofuran-4,7-dione and 2-hydroxybenzoic acid was obtained through Gas Chromatography-Mass spectrometry (GC-MS). A. sydowii exhibited promising potentials in the removal of PAHs.

High-mobility organic single-crystalline transistors with anisotropic transport based on high symmetrical H-shaped heteroarene derivatives

To reveal the influence of synergistic effect of non-covalent forces on the FET performance, two highly symmetrical H-shaped heteroarene derivatives anthra[2,1-b:3,4-b ‘:6,5-b ”:7,8-b ”’]tetra(benzothiophene) (ATBT) and anthra[2,1-b:3,4-b ‘:6,5-b ”:7,8-b ”’]tetra(benzofuran) (ATBF) as novel two-dimensional (2D) organic semiconductor materials were synthesized. The thermal, optical and electrochemical properties of ATBT and ATBF were investigated and high stability was confirmed. Single crystal XRD of ATBT confirmed the close pi-pi stacking due to the wider pi-conjugation framework and four S atoms sited on both sides of each molecule could produce eight SMIDLINE HORIZONTAL ELLIPSISS contacts with neighbouring molecules. Mobility of up to 15.6 cm(2)V(-1)s(-1)could be achieved for the single-crystalline field effect transistor, which was fabricated by the ‘two-dimensional organic-ribbon mask’ technique based on the individual ATBT microribbon. The strong anisotropy along different crystal axes is consistent with the molecular arrangement, which was evidenced by XRD, TEM and corresponding selected-area electron diffraction pattern. Moreover, the analogue ATBF shows lower FET performance due to lack of SMIDLINE HORIZONTAL ELLIPSISS contacts in comparison to that of ATBT, which reflects that the synergistic effect of non-covalent forces has an important influence on the molecular aggregation and electrical properties.

Novel radiogallium-labeled pyridyl benzofuran derivative for detection of amylin aggregates in pancreas

Introduction: The deposition of islet amyloid composed of amylin aggregates is related to p-cell mass dysfunction in type 2 diabetes mellitus (T2DM), and it may be involved in the development and progression of T2DM. In this study, we newly designed, synthesized, and evaluated a radiogallium-labeled pyridyl benzofuran derivative ([Ga-67(/)68]GPBF) as an amylin imaging probe. Methods: An in vitro competitive inhibition assay was performed to determine the binding affinity for amylin aggregates. An in vitro autoradiographic study was carried out using pancreatic sections from a T2DM patient. A biodistribution of [Ga-67]GPBF in normal mice was evaluated. Finally, we carried out ex vivo autoradiography using mouse transplanted with amylin aggregates. Results: GPMFexhibited binding affinity for amylin aggregates in vitro. In addition, [Ga-67]GPBF dearly labeled islet amyloids in in vitro autoradiography of a T2DM pancreatic section. In a biodistribution study using normal mice, [Ga-67]GPEIF showed initial uptake into the pancreas, but non-specific accumulation in the liver, spleen, and pancreas was also observed. Furthermore, an ex vivo autoradiogram demonstrated that [Ga-67]GPBF bound to amylin aggregates in the pancreas of the amylin aggregate-transplanted mice. Conclusions: These results provide useful insights into the development of radiogallium labeled probes that target amylin aggregates in the T2DM pancreas. (C) 2020 Elsevier Inc. All rights reserved.

Unusual structural changes as a result of weathering benzofuran-based diarylethenes in simulated sunlight

While the products that result from photochemical degradation of thiophene-based diarylethenes have been documented, those from the benzofuran counterparts have been less extensively studied. In this article, we present two unusual and yet to be reported degradation products of a dialkoxybenzofuran derivative, characterized by a combination of spectroscopy techniques and X-ray crystallography. We show that these products are generated by due to the specific substitution position of the alkoxy groups on the benzofuran heterocycle. We also propose reasonable mechanisms for the degradation pathways and products formation, which are supported by equivalent studies using isomeric monoalkoxy versions.

A benzofuran-beta-alaninamide based turn-on fluorescent chemosensor for selective recognition of Fe3+ ions

A benzofuran-beta-alaninamide based chemosensor, 3-(3-((4-methylbenzyl)amino)propanamido)benzofuran-2-carboxamide (BAA), was designed and synthesized for selective detection of Fe3+ ions. The binding ability of BAA towards Fe3+ in DMSO/H2O solution (9/1, v/v) has been studied by UV-vis absorption and fluorescence spectroscopy. Interestingly, the probe BAA exhibits an excellent turn-on fluorescence enhancement at 424 nm with an excitation wavelength of 290 nm. The quantum yield was determined to be 0.248 for BAA and 0.447 for the iron complex. The limit of detection (LOD) was calculated to be 1.3 mu M and 0.067 mu M by UV-vis absorption and fluorescence methods respectively. These values are much lower than that of US Environmental Protection Agency guidelines for drinking water (5.37 mu M). Job’s plot measurement evidenced the 2 : 1 binding stoichiometry for the complex formed between BAA and Fe3+. Moreover, the binding interaction of BAA towards Fe3+ was confirmed by density functional theory (DFT) studies. Finally, the real sample analysis proved that the probe BAA was more suitable for the detection of Fe3+.

Structurally Modified Cyclopenta[b]benzofuran Analogues Isolated from Aglaia perviridis

Four new cyclopenta[b]benzofuran derivatives based on an unprecedented carbon skeleton (1-4), with a dihydrofuran ring fused to dioxanyl and aryl rings, along with a new structural analogue (5) of 5”’-episilvestrol (episilvestrol, 7), were isolated from an aqueous extract of a large-scale re-collection of the roots of Aglaia perviridis collected in Vietnam. Compound 5 demonstrated mutarotation in solution due to the presence of a hydroxy group at C-2”’, leading to the isolation of a racemic mixture, despite being purified on a chiral-phase HPLC column. Silvestrol (6) and episilvestrol (7) were isolated from the most potently cytotoxic chloroform subtraction of the roots. All new structures were elucidated using 1D and 2D NMR, HRESIMS, IR, UV, and ECD spectroscopic data. Of the five newly isolated compounds, only compound 5 exhibited cytotoxic activity against a human colon cancer (HT-29) and human prostate cancer cell line (PC-3), with IC50 values of 2.3 mu M in both cases. The isolated compounds (1-5) double the number of dioxanyl ring-containing rocaglate analogues reported to date from Aglaia species and present additional information on the structural requirements for cancer cell line cytotoxicity within this compound class.

(4+3) cycloadditions of allenyl ether-derived oxygen-stabilized oxyallyls with furans

(4 + 3) cycloadditions between allenyl ethers and furans are described. The reaction features an in situ formation of oxygen-stabilized oxyallyls via epoxidations of allenyl ethers in the presence of H2PO4-. The multiple interactions between the oxygen-stabilized oxyallyl species and H2PO4- were studied using DFT calculations for rationalization of the regio- and diastereoselectivity of this cycloaddition. The utilities of this cycloaddition have been demonstrated by converting the (4 + 3) cycloadduct into the cyclohepta[b]benzofuran skeleton of frondosin B in two steps.

The charge transfer and charge regeneration in the ground and excited states of the dyes are established. The photon to electron energy transfer from the dye (quercetin) to the semiconductor (TiO2) surface is analyzed based on intramolecular charge transfer.
