Access to Corrole-Appended Persubstituted Benzofurans by a Multicomponent Reaction: The Dual Role of p-Chloranil

A multicomponent reaction among dipyrranes, arylpropargyl aldehydes, and p-chloranil leading to 10-(benzofuran-2yl)corroles is described. p-Chloranil was identified as a crucial reagent playing a twofold role: an oxidant taking part in the formation of the corrole macrocycle and a component undergoing heteroannulation to the incipient 10-arylethynylcorrole. A series of corroles bearing persubstituted benzofuran-2-yl moieties have been synthesized, and their fundamental electronic properties have been studied via UV-vis absorption and fluorescence spectroscopies.

Chiral Bronsted Acid-Catalyzed Asymmetric 1,4-Addition of Benzofuran-Derived Azadienes with 3-Substituted indoles

A chiral phosphoric acid-catalyzed asymmetric 1,4-addition of benzofuran-derived azadienes with 3-substituted indoles has been established, which offered enantioenriched tri(hetero)arylmethane products in generally good yields (up to 98 %) and high enantioselectivities (up to 99 : 1 er). This reaction has not only realized the application of chiral phosphoric acid as a competent catalyst in the asymmetric transformations of benzofuran-derived azadienes, but also has accomplished the task of developing chiral Bronsted acid-catalyzed asymmetric 1,4-additions of benzofuran-derived azadienes, which will enrich the research contents of chiral phosphoric acid catalysis and the chemistry of benzofuran-derived azadienes.

Isoparvifuran isolated from Dalbergia odorifera attenuates H2O2-induced senescence of BJ cells through SIRT1 activation and AKT/mTOR pathway inhibition

Isoparvifuran is a benzofuran compound isolated from the heartwood of Dalbergia odorifera. Related research reported that isoparvifuran has antioxidant property. However, it is unclear whether isoparvifuran has anti-aging effects. In this research, we established an aging model, hydrogen peroxide (H2O2)-induced BJ cell senescence, to explore the protective effect of isoparvifuran on cell senescence and its related mechanisms. Our results revealed that isoparvifuran obviously attenuated H2O2-induced cell senescence, increased the cell proliferation rate,and reversed senescence-associated molecular markers expression such as cyclin D1, pRb, caveolin-1, ace-p53, p21 and p16. Moreover, isoparvifuran dose and time dependently increased the expression level of Sirtuin 1 (SIRT1) in BJ cells. The inhibition of SIRT1 obviously reversed the reduction of SA-beta-gal activity and the alteration of senescence-associated molecular markers induced by isoparvifuran. Additionally, isoparvifuran also inhibited H2O2-induced AKT and S6 phosphorylation and increase of SA-beta-gal activity. In summary, isoparvifuran protects BJ cells from H2O2-induced premature senescence, the anti-senescence effect of isoparvifuran is associated with the activation of SIRT1 and the suppression of AKT/mTOR signaling pathway.

A series of new benzofuran/oxadiazole hybrids (8a-n) was synthesized from 2H-chromene-3-carbonitriles (3a-c) through the multistep synthetic methodology, and these hybrids are known to exhibit anticancer activities. All the compounds were evaluated for their in vitro cytotoxicity against the HCT116 and MIA PaCa2 cell lines. Compounds 6a (IC50: 9.71 +/- 1.9 mu M), 6b (IC50: 7.48 +/- 0.6 mu M), and 6c (IC50: 3.27 +/- 1.1 mu M) displayed a significant cytotoxic activity, whereas compounds 8d and 8e exhibited good activity against both cell lines. The depletion of glycogen synthase kinase-3 beta (GSK3 beta) induces apoptosis through the inhibition of basal NF-kappa B activity in HCT116 colon cancer cells and MIA PaCa2 pancreatic cancer cells. Molecular docking of compounds 6a, 6b, 6c, 8d, and 8e with GSK3 beta demonstrated the best binding affinity, correlating with the biological activity assay. Furthermore, the structure-activity relationship of these novel compounds reveals promising features for their use in anticancer therapy.

Characterization of a Dibenzofuran-degrading strain of Pseudomonas aeruginosa, FA-HZ1

Dibenzofuran (DBF) derivatives have caused serious environmental problems, especially those produced by paper pulp bleaching and incineration processes. Prominent for its resilient mutagenicity and toxicity, DBF poses a major challenge to human health. In the present study, a new strain of Pseudomonas aeruginosa, FA-HZ1, with high DBF-degrading activity was isolated and identified. The determined optimum conditions for cell growth of strain FA-HZ1 were a temperature of 30 degrees C, pH 5.0, rotation rate of 200 rpm and 0.1 mM DBF as a carbon source. The biochemical and physiological features as well as usage of different carbon sources by FA-HZ1 were studied. The new strain was positive for arginine double hydrolase, gelatinase and citric acid, while it was negative for urease and lysine decarboxylase. It could utilize citric acid as its sole carbon source, but was negative for indole and H2S production. Intermediates of DBF 1,2-dihydroxy-1,2-dihydrodibenzofuran, 1,2-dihydroxydibenzofuran, 2-hydroxy-4-(3′-oxo-3’H-benzofuran-2′-yliden)but-2-enoic acid, 2,3-dihydroxybenzofuran, 2-oxo-2-(2′-hydrophenyl)lactic acid, and 2-hydroxy-2-(2′-hydroxyphenyl)acetic acid were detected and identified through liquid chromatography-mass analyses. FA-HZ1 metabolizes DBF by both the angular and lateral dioxygenation pathways. The genomic study identified 158 genes that were involved in the catabolism of aromatic compounds. To identify the key genes responsible for DBF degradation, a proteomic study was performed. A total of 1459 proteins were identified in strain FA-HZ1, of which 100 were up-regulated and 104 were down-regulated. A novel enzyme HZ6359 dioxygenase, was amplified and expressed in pET-28a in E. coli BL21(DE3). The recombinant plasmid was successfully constructed, and was used for further experiments to verify its function. In addition, the strain FA-HZ1 can also degrade halogenated analogues such as 2, 8-dibromo dibenzofuran and 4-(4-bromophenyl) dibenzofuran. Undoubtedly, the isolation and characterization of new strain and the designed pathways is significant, as it could lead to the development of cost-effective and alternative remediation strategies. The degradation pathway of DBF by P. aeruginosa FA-HZ1 is a promising tool of biotechnological and environmental significance. (C) 2019 Elsevier Ltd. All rights reserved.
