Abstract:

A novel series of azolylalkyloxy compounds was designed, synthesized and evaluated for antipicornaviral activity. Several of the compounds exhibited in vitro activity comparable to that of Disoxarll. An investigation of qualitative structure-activity relationships indicated that the optimal length of the alkyI chain is six or seven carbon atoms, with seven being marginally superior. The effect of different azole moieties on activity was relatively small, with 3-methylisoxazole and 4-methylthiazole being most effective. The nature of the oxy substituent was found to be extremely important for a

Abstract:

The contamination of the environment has been a global issue, and bioremediation is proposed as an option to clean up the contamination sites with the promising utilization of bacterial community capabilities. The indigenous bacterial community in the landfill leachate is recognized to carry enzymes for the degradation of contaminants such as dioxin congeners, the dibenzofuran. Environmental factors have been known to influence the process to achieve successful biodegradation, and the optimized conditions may speed up the biodegradation process. Thus, this study was conducted to optimize the s

Abstract:

ABSTRACT The genes responsible for angular dioxygenation of dibenzofuran in actinomycetes were cloned by using a degenerate set of PCR primers designed by using conserved sequences of the dioxygenase alpha subunit genes. One sequence of alpha subunit genes was commonly amplified from four dibenzofuran-utilizing actinomycetes: Terrabacter sp. strains YK1 and YK3, Rhodococcus sp. strain YK2, and Microbacterium sp. strain YK18. A 5.2-kb PstI fragment encoding the alpha and beta subunits of the terminal dioxygenase, ferredoxin, and ferredoxin reductase (designated dfdA1 to dfdA4, respectively) was

Abstract:

Fluorene and its three heteroatomic analogs, dibenzofuran, dibenzothiophene, and carbazole, are environmental contaminants in areas impacted by spills of creosote. In addition, dibenzofuran has been used as an insecticide, and it is formed from the photolysis of chlorinated biphenyl ethers. Many biodegradation studies of dibenzofuran have considered it as a model for chlorinated dibenzofurans, which are of greater environmental concern. This paper reviews the bacterial degradation of fluorene and its analogs. These compounds are susceptible to three different modes of initial oxidation: (i) th

Abstract:

Regioselective functionalization of core per-substituted boron dipyrromethenes (BODIPYs) has been achieved efficiently based on tetrabromoBODIPY, which affords a series of dibenzofuran-fused chromophores, via a regioselective nucleophilic substitution reaction followed by direct palladium-catalyzed two-fold intramolecular ring fusion. These rigid dibenzofuran-fused BODIPYs showed impressive photophysical properties such as clearly red-shifted absorption and emission bands, enhanced absorption coefficients upon and intense fluorescence (close to unity).

Abstract:

Photochemical cyclization reactions of iodinated diphenyl ethers to produce dibenzofuran derivatives have been studied. While U.V. irradiation of the thyroid hormone thyroxine produces a complex mixture of products, treatment of the thyroid hormone analogue 3,5-diiodo-4-(4'-methyoxphenoxy)nitrobenzene with U.V. light yielded 4-iodo-8-methoxy-2-nitrodibenzofuran (34%) in a clean reaction. The functionalized dibenzofuran framework produced in this reaction has considerable potential for the development of novel, rigid thyroid hormone analogues.

Abstract:

ABSTRACT Cells of the gram-negative bacterium Ralstonia sp. strain SBUG 290 grown in the presence of biphenyl are able to cooxidize dibenzofuran which has been 1,2-hydroxylated. Meta cleavage of the 1,2-dihydroxydibenzofuran between carbon atoms 1 and 9b produced 2-hydroxy-4-(3′-oxo-3′H-benzofuran-2′-yliden)but-2-enoic acid, which was degraded completely via salicylic acid. The presence of these intermediates indicates a degradation mechanism for dibenzofuran via lateral dioxygenation by Ralstonia sp. strain SBUG 290.

Abstract:

ABSTRACT In this study, the genes involved in the initial attack on fluorene by Sphingomonas sp. strain LB126 were investigated. The α and β subunits of a dioxygenase complex (FlnA1-FlnA2), showing 63 and 51% sequence identity, respectively, to the subunits of an angular dioxygenase from the gram-positive dibenzofuran degrader Terrabacter sp. strain DBF63, were identified. When overexpressed in Escherichia coli, FlnA1-FlnA2 was responsible for the angular oxidation of fluorene, 9-hydroxyfluorene, 9-fluorenone, dibenzofuran, and dibenzo-p-dioxin. Moreover, FlnA1-FlnA2 was able to oxidize polycy

Abstract:

Four regioisomers were synthesized for use as bipolar host materials for phosphorescent organic light-emitting diodes (PhOLEDs) by classic cross-coupling reactions using cyanofluorene and fused dibenzofuran and were readily purified.

Abstract:

The planarity and rigidity of dibenzofuran inverts the docking preference for increasingly bulky R-OH solvent molecules, compared to the closely related diphenyl ether. Now, London dispersion favors OH⋯π hydrogen bonding.

Abstract:

ABSTRACT We characterized the ability of a yeast to cleave the aromatic structure of the dioxin-like compound dibenzofuran. The yeast strain was isolated from a dioxin-contaminated soil sample and identified asTrichosporon mucoides. During incubation of glucose-pregrown cells with dibenzofuran, six major metabolites were detected by high-performance liquid chromatography. The formation of four different monohydroxylated dibenzofurans was proven by comparison of analytical data (gas chromatography-mass spectrometry) with that for authentic standards. Further oxidation produced 2,3-dihydroxydibe
