Selenium-Catalyzed Carbonylative Synthesis of 3,4-Dihydroquinazolin-2(1H)-one Derivatives with TFBen as the CO Source

An efficient and general carbonylative procedure for the synthesis of 3,4-dihydroquinazolin-2(1H)-one from 1-(halomethyl)-2-nitrobenzenes and aryl/alkyl amines have been explored. In this approach, to avoid of using toxic CO gas, a solid and stable CO precursor, TFBen (benzene-1,3,5-triyl triformate), was utilized. With elemental selenium as the catalyst, a variety of aryl/alkyl amines has been tolerated well to afford the corresponding 3,4-dihydroquinazolin-2(1H)-one products in moderate to excellent yields under mild reaction condition.

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.

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.

Identification of novel STAT3 inhibitors bearing 2-acetyl-7-phenylamino benzofuran scaffold for antitumour study

Signal transducer and activator of transcription 3 (STAT3) is identified as a promising target for multiple cancer therapy and attracts widespread concern. Herein, we reported the discovery of a series of 2-acetyl-7-phenylamino benzofuran derivatives as STAT3 inhibitors using scaffold fusion strategy. Further structure activity relationship study led to the discovery of compound C6, which displayed the most potent anti-proliferation activities against MDA-MB-468 cells (IC50 = 0.16 mu M). Western blot assay demonstrated that C6 inhibited the activation of STAT3 (Tyr705) without influencing the phosphorylation of STAT1 (Tyr701). Further mechanistic studies indicated that C6 caused a notable G2/M cycle-arresting and early apoptosis in a concentration-dependent manner in MDA-MB468 cells. Finally, molecular modelling study elucidated the binding mode of C6 in STAT3 SH2 domain.

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.

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.

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.

Probing 2-acetylbenzofuran hydrazones and their metal complexes as alpha-glucosidase inhibitors

Inhibition of alpha-glucosidase is one of the important approaches in designing antidiabetic drugs for its role in decrease of the carbohydrates digestion to avoid post-prandial increase in blood sugar levels in diabetic patients. In the present study we designed a novel series of 2-acetylbenzofuran hydrazones (L1-L7) and their metal (II) complexes Cu (II), Co (II), Zn (II) and Mn (II) (8-29) and screened for inhibitory activity against the yeast alpha-glucosidase. The synthesis of hydrazones incorporated the use of I-2 as a catalyst which resulted in excellent yield of 94%. The ligand L3, showed good activity (IC50 = 47.51 +/- 0.86 mu M) while its metal complex (10) showed potent activity (IC50 = 1.15 +/- 0.001 mu M) compared to reference acarbose IC50 = 378.25 +/- 0.12 mu M. Similarly, the Cu (II) complexes with ligands L5 and L6 showed excellent alpha-glucosidase inhibition (IC50 = 0.15 +/- 0.003 12 and 0.21 +/- 0.002 mu M for 13, respectively) whereas, the metal complexes of Co (II), Mn (II), and Zn (II) showed moderate to poor inhibitory activities against alpha-glucosidase. The The findings are supported by the ligands and enzyme interactions through molecular docking studies. In conclusion, it is indicated that metal complexes of 2-acetylbenzofuran hydrazones have good potential for research leading to antidiabetic therapies.
