Three new 3-formyl-2-arylbenzofurans from Itea yunnanensis and their anti-hepatocellular carcinoma effects

Five 3-formyl-2-arylbenzofuran derivatives, including three new compounds (1-3) and two known analogues (4-5), were identified from the 95% EtOH extract of Itea yunnanensis. Extensive spectroscopic analyses were performed for the structure elucidation of all new benzofurans, and single-crystal X-ray diffraction analyses were further employed for the structure verification of iteafuranals C (1) and D (2). In MTT assay, iteafuranal E (3) and iteafuranal A (4) displayed significant growth inhibition effect on SK-Hep-1 cells with IC50 values of 5.365 mu M and 6.013 mu M, respectively. The colony formation assay of 3 and 4 further confirmed their remarkable inhibitory effect on cell growth. Preliminary mechanism study demonstrated that 3 remarkably down-regulated the phosphorylation level of ERK, which suggested 3 could inhibit cell growth and induce apoptosis of SK-Hep-1 cells by blocking RAS/RAF/MEK/ERK signaling pathway. This study highlighted the potential of 3-fomyl-2-benzofuran derivatives as novel lead compounds to treat Hepatocellular carcinoma.

Dihydrophthalazinediones accelerate amyloid beta peptide aggregation to nontoxic species

The production and accumulation of toxic amyloid plaques is one of the hallmarks of Alzheimer’s disease (AD). Amyloid beta (A beta) peptides undergo self-aggregation to form soluble oligomers, protofibrils and insoluble fibrils. This process is termed as amyloidogenesis and is a major contributor to the observed neuronal damage and memory impairment in the AD brain. Therefore, modulation of A beta aggregation process is considered to be an effective target to prevent neuronal damage under AD conditions. Modulation of amyloidogenesis involves inhibition of aggregation to form a toxic species or acceleration to drive the aggregation process to form species that are nontoxic by employing well-designed external ligands. In this context, we report a set of 2,3-dihydrophthalazine-1,4-dione (dihydrophthalazinedione, Phz) based small molecules (Phz 1-4) to modulate the A beta 42 aggregation and in cellular toxicity. Our detailed study (thioflavin T fluorescence assay, dot blot and transmission electron microscopy analysis) revealed fluorine containing Phz 4 as the potent modulator of A beta 42 aggregation by accelerating the process to form nontoxic aggregated species through hydrophobic and halogen interactions. A beta 42 aggregates formed in the presence of Phz 4 are mostly nontoxic when compared to the normal amyloid aggregates in the cellular milieu (PC12 cells). This study established that the hydrophobic and halogen interactions can be employed to develop anti-AD drug candidates. The excellent cell viability, effective modulation of A beta 42 aggregation to form nontoxic species and cellular (neuronal) rescue by Phz 4 offer a novel platform to develop therapeutic strategies for AD.

Cu-Mediated Amination of (Hetero)Aryl C-H bonds with NH Azaheterocycles

Direct synthesis of N-(hetero)arylated heteroarenes has been realized through Cu-mediated C-N coupling of NH azaheterocycles with aryl C-H bonds under aerobic conditions. This method features a broad scope of both heterocyclic arenes (pyridine, quinoline, pyrazole, imidazole, furan, thiophene, benzofuran, and indole) and NH azaheterocycles (imidazole, pyrazole, indole, azindole, purine, indazole, benzimidazole, pyridone, carbazole), providing a versatile method for the synthesis of pharmaceutically important N-(hetero)arylated heteroarenes. The versatility of this reaction was further demonstrated through late-stage modification of marketed drugs and the synthesis of a key intermediate for accessing a class of angiotensin II receptor 1 antagonists.

Catalytic Pyrolysis of Guaiacol over Ni/La-Modified Hierarchical HZSM-5

Catalytic pyrolysis of guaiacol as a model compound of lignin was conducted to explore the lignin pyrolysis mechanism in this study. The effects of catalyst and temperature on product distribution were studied. Five catalysts were tested including HZSM-5, hierarchical HZSM-5, metal-modified hierarchical HZSM-5 catalysts. And the Ni/La bimetallic hierarchical HZSM-5 (NiLa/HZ-SH) contributes to the achievement of high conversion and selectivity in catalytic pyrolysis of guaiacol. we obtained the yields of monocyclic aromatic hydrocarbons over NiLa/HZ-SH (550 degrees C): Phenol (23.01%), Benzofuran (6.68%), Salicylaldehyde (1.54%), 2-Methylphenol (31.48%), 4-Methylphenol (6.54%), 2-Ethylphenol (14.89%), 4-Vinylphenol (1.45%) and Catechol (8.67%), and the maximal yields of these monocyclic aromatic hydrocarbons is 94.26%. Moreover, the yield of polycyclic aromatic hydrocarbons (PAH) as the non-target product reached a minimum of 1.46% over NiLa/HZ-SH, while it was 16.88% without catalyst. In addition, catalyst stability was investigated, the reason that led to the decrease of target products could be the acidity and surface area of catalysts decreased as the coke blocked the pore channels, spent catalyst can be successfully regenerated through calcination treatment. Finally, based on the experiment results in this work and other published studies, a guaiacol pyrolysis mechanism was summarized and proposed aiming to understand the lignin pyrolysis process.

Novel benzofuran-based sulphonamides as selective carbonic anhydrases IX and XII inhibitors: synthesis and in vitro biological evaluation

Pursuing on our efforts toward searching for efficient hCA IX and hCA XII inhibitors, herein we report the design and synthesis of new sets of benzofuran-based sulphonamides (4a,b, 5a,b, 9a-c, and 10a-d), featuring the zinc anchoring benzenesulfonamide moiety linked to a benzofuran tail via a hydrazine or hydrazide linker. All the target benzofurans were examined for their inhibitory activities toward isoforms hCA I, II, IX, and XII. The target tumour-associated hCA IX and XII isoforms were efficiently inhibited with K (I)s spanning in ranges 10.0-97.5 and 10.1-71.8 nM, respectively. Interestingly, arylsulfonehydrazones 9 displayed the best selectivity toward hCA IX and XII over hCA I (SIs: 39.4-250.3 and 26.0-149.9, respectively), and over hCA II (SIs: 19.6-57.1 and 13.0-34.2, respectively). Furthermore, the target benzofurans were assessed for their anti-proliferative activity, according to US-NCI protocol, toward a panel of sixty cancer cell lines. Only benzofurans 5b and 10b possessed selective and moderate growth inhibitory activity toward certain cancer cell lines.

Alkoxyphenyl or alkylphenyl side-chained Thieno[2,3-f]benzofuran polymer for efficient non-fullerene solar cells

In this work, two novel thieno[2,3-f]benzofuran (TBF) unit, with fluorinated alkoxyphenyl or alkylphenyl side chain, were synthesized and characterized. Based on these TBF donor unit and benzodithiophene-4,8-dione (BDD) acceptor, two novel polymers, PTBFPF-BDD and PTBFP-BDD, were prepared by Stille coupling reaction. The conjugated side chain effects on the thermogravimetric, optical, electrochemical, and photovoltaic properties of these polymers were systematically investigated. Both polymers exhibited desirable power conversion efficiency (PCE) of more than 8% after thermal annealing. PTBFP-BDD:ITIC-based devices achieved higher PCE of 8.50% with an open-circuit voltage (V-OC) of 0.88 V, a short-circuit current density (J(SC)) of 16.01 mA/cm(2) and a fill factor (FF) of 59.80%. In addition, the devices based on PTBFPF-BDD:ITIC showed an enhanced V-OC of 0.92 V due to down-shifted the highest occupied molecular orbital (HOMO) energy levels. The results indicate that the alkylphenyl/alkoxyphenyl substitution of TBF donor units is promising strategy for improving PCE of PSCs. (C) 2020 Elsevier Ltd. All rights reserved.

Synthesis, In Vitro Evaluation and Molecular Docking of the 5-Acetyl-2-aryl-6-hydroxybenzo[b]furans against Multiple Targets Linked to Type 2 Diabetes

The 5-acetyl-2-aryl-6-hydroxybenzo[b]furans 2a-h have been evaluated through in vitro enzymatic assay against targets which are linked to type 2 diabetes (T2D), namely, alpha-glucosidase, protein tyrosine phosphatase 1B (PTP1B) and beta-secretase. These compounds have also been evaluated for antioxidant activity using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free-radical scavenging method. The most active compounds against alpha-glucosidase and/or PTP1B, namely, 4-fluorophenyl 2c, 4-methoxyphenyl 2g and 3,5-dimethoxyphenyl substituted 2h derivatives were also evaluated for potential anti-inflammatory properties against cyclooxygenase-2 activity. The Lineweaver-Burk and Dixon plots were used to determine the type of inhibition on compounds 2c and 2h against alpha-glucosidase and PTP1B receptors. The interactions were investigated in modelled complexes against alpha-glucosidase and PTP1B via molecular docking.
