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 facile approach to hybrid compounds containing a tricyclic diterpenoid and fluorine-substituted heterocycles

2,3-Butadienes have become valuable building blocks in the synthesis of various heterocyclic compounds. The Pd-catalyzed cross-coupling and cyclization reaction of N-(2,3-butadienyl)carboxamide of isopimaric acid with fluorine-substituted 2-iodophenols proceeds with the formation of optically active fluorinated benzofuran and benzopyrane derivatives of isopimaric acid. This transformation opens a potential route to the synthesis of hybrid compounds containing a tricyclic diterpenoid moiety and several fluorinated benzoannelated heterocycles.

Rhodium-Catalyzed Successive C-H Bond Functionalizations To Synthesize Complex Indenols Bearing a Benzofuran Unit

An efficient rhodium-catalyzed redox-neutral annulations of N-phenoxyacetamides and ynones via successive double C-H bond activations has been developed. A series of novel and complex indenols bearing a benzofuran unit were generated with moderate to excellent regioselecetivities under mild conditions. Adding N-ethylcyclohexanamine (CyNHEt) could restrict the formation of the mono C-H bond activation byproduct, which is not the intermediate of the reaction demonstrated via the mechanistic investigations.

Transition-Metal-Free Synthesis of Heterobiaryls through 1,2-Migration of Boronate Complex

The synthesis of a diverse range of heterobiaryls has been achieved by a transition-metal-free sp(2)-sp(2) cross-coupling strategy using lithiated heterocycle, aryl or heteroaryl boronic ester and an electrophilic halogen source. The construction of heterobiaryls was carried out through electrophilic activation of the aryl-heteroaryl boronate complex, which triggered 1,2-migration from boron to the carbon atom. Subsequent oxidation of the intermediate boronic ester afforded heterobiaryls in good yield. A comprehensive B-11 NMR study has been conducted to support the mechanism. The cross coupling between two nucleophilic cross coupling partners without transition metals reveals a reliable manifold to procure heterobiaryls in good yields. Various heterocycles like furan, thiophene, benzofuran, benzothiophene, and indole are well tolerated. Finally, we have successfully demonstrated the gram scale synthesis of the intermediates for an anticancer drug and OLED material using our methodology.

Tuning the emissive characteristics of TADF emitters by fusing heterocycles with acridine as donors: highly efficient orange to red organic light-emitting diodes with EQE over 20%

The development of highly efficient orange-red organic thermally activated delayed fluorescence (TADF) emitters is currently challenging. Herein, we reported two new emitters, namely, BTDMAc-NAI and BFDMAc-NAI with benzofuran and benzothiophene fused to the acridine frame. Inspiringly, the target emitters showed very different emissions from orange to pure red, with the emission peak of BTDMAc-NAI red-shifting to 650 nm. Meanwhile, these two emitters showed distinct TADF characteristics and high photoluminescence quantum yields (PLQYs). As a result, the orange-red OLED based on BFDMAc-NAI demonstrated an excellent performance with external quantum efficiency (EQE) beyond 20%. This work unveils the great potential of the fused polycycle molecular design in exploiting new orange-red TADF emitters for high-performance OLEDs.

Synthesis and in vitro study of nitro- and methoxy-2-phenylbenzofurans as human monoamine oxidase inhibitors

A new series of 2-phenylbenzofuran derivatives were designed and synthesized to determine relevant structural features for the MAO inhibitory activity and selectivity. Methoxy substituents were introduced in the 2-phenyl ring, whereas the benzofuran moiety was not substituted or substituted at the positions 5 or 7 with a nitro group. Substitution patterns on both the phenyl ring and the benzofuran moiety determine the affinity for MAO-A or MAO-B. The 2-(3-methoxyphenyl)-5-nitrobenzofuran 9 was the most potent MAO-B inhibitor (IC50 = 0.024 mu M) identified in this series, whereas 7-nitro-2-phenylbenzofuran 7 was the most potent MAO-A inhibitor (IC50 = 0.168 mu M), both acting as reversible inhibitors. The number and position of the methoxyl groups on the 2-phenyl ring, have an important influence on the inhibitory activity. Molecular docking studies confirmed the experimental results and highlighted the importance of key residues in enzyme inhibition.

Directing-Group-Assisted Transition-Metal-Catalyzed Direct C-H Oxidative Annulation of Arenes with Alkynes for Facile Construction of Various Oxygen Heterocycles

The most recent advances in the construction of oxygen heterocycles by the directing-group-assisted transition-metal-catalyzed direct oxidative annulation of arenes with diverse alkynes are summarized in this review. More than 140 recent research papers and many closely related reviews are referenced in this paper. Nine different oxygen heterocycles frameworks are discussed. Several traditional transition-metal catalysts as well as some classical non-noble metals are utilized to promote the annulation. Three plausible controlling models are disclosed to clarify the excellent regioselectivity outcomes achieved in case of unsymmetrical alkyne substrates.
