Borane-Catalyzed Stereoselective C-H Insertion, Cyclopropanation, and Ring-Opening Reactions

Lewis acidic boranes have been shown to be effective metal-free catalysts for highly selective reactions of donor-acceptor diazo compounds to a range of substrates. The reactions of alpha-aryl alpha-diazoesters with nitrogen heterocycles indole or pyrrole selectively generate C3 and C2 C-H insertion products, respectively, in good to excellent yields even when using unprotected indoles. Alternatively, benzofuran, indene, and alkene substrates give exclusively cyclopropanated products with alpha-aryl alpha-diazoesters, whereas the reactions with furans lead to ring-opening. Comprehensive theoretical calculations have been used to explain the differing reactivities and high selectivities of these reactions. Overall, this work demonstrates the selective metal-free catalytic reactions of alpha-aryl alpha-diazoesters with (hetero)cycles and alkenes. This simple, mild reaction protocol represents an alternative to the commonly used precious metal systems and may provide future applications in the generation of biologically active compounds.

Highly Aromatic Flavan-3-ol Derivatives from Palaeotropical Artocarpus lacucha Buch.-Ham Possess Radical Scavenging and Antiproliferative Properties

Phytochemical investigation of leaves and stembark of Artocarpus lacucha collected in Thailand resulted in three yet undescribed isomeric flavan-3-ol derivatives (1-3), the four known compounds gambircatechol (4), (+)-catechin (5), (+)-afzelechin (6) and the stilbene oxyresveratrol (7). Compounds 1 to 3 feature 6/6/5/6/5/6 core structures. All structures were deduced by NMR and MS, while density functional theory (DFT) calculations on B3LYP theory level were performed of compounds 1 to 3 to support the stereochemistry in positions 2 and 3 in the C-ring. Possible biosynthetic pathways leading to 4 are discussed. The DPPH assay revealed high radical scavenging activities for 1 (EC50 = 9.4 +/- 1.0 mu mol mL(-1)), 2 (12.2 +/- 1.1), 3 (10.0 +/- 1.5) and 4 (19.0 +/- 2.6), remarkably lower than ascorbic acid (EC50 = 34.9) and alpha-tocopherol (EC50 = 48.6). A cytotoxicity assay revealed moderate but consistent antiproliferative properties of 1 in CH1/PA-1 (ovarian teratocarcinoma) and SW480 (colon carcinoma) cells, with IC50 values of 25 +/- 6 and 34 +/- 4 mu M, respectively, whereas effects in A549 (non-small cell lung cancer) cells were rather negligible. The performed DCFH-DA assay of 1 in the former cell lines confirmed potent antioxidative effects even in the cellular environment.

Synergistic effect of highly dispersed Ru and moderate acid site on the hydrodeoxygenation of phenolic compounds and raw bio-oil

Hydrodeoxygenation (HDO) is an indispensable and important reaction in the fuel production process. Generally, the catalysts for HDO contain metal or acidic active sites, and the co-existence of them can significantly promote the HDO performance. While the subtle interaction between metal and acidic active sites is still not very clear. Herein, a series of Ru-based catalysts with different supports were prepared by photochemical method to obtain both of the high Ru dispersion and the moderate acidity. Among the catalysts with various supports, Ru/TiO2-Al2O3 showed the most efficient performance in the HDO process of phenolic compounds. Guaiacol was converted into cyclohexane with above 90% selectivity at 240 degrees C. Other typical phenolic compounds, including phenol, anisole, p-cresol, 1,2-dimethoxybenzene, benzofuran, eugenol and dibenzyl ether, were all transformed into the corresponding cycloalkanes with yield close to 100%. The synergistic effect between highly dispersed Ru and moderate acid site played the key role for the enhanced production of hydrocarbon fuels. Moreover, this catalytic system was also effective on the raw bio-oil upgradation for producing high yield of hydrocarbons and alkylphenols, which has the potential to be used as biofuels.

Novel tacrine-benzofuran hybrids as potential multi-target drug candidates for the treatment of Alzheimer’s Disease

Pursuing the widespread interest on multi-target drugs to combat Alzheimer ‘ s disease (AD), a new series of hybrids was designed and developed based on the repositioning of the well-known acetylcholinesterase (AChE) inhibitor, tacrine (TAC), by its coupling to benzofuran (BF) derivatives. The BF framework aims to endow the conjugate molecules with ability for inhibition of AChE (bimodal way) and of amyloid-beta peptide aggregation, besides providing metal (Fe, Cu) chelating ability and concomitant extra anti-oxidant activity, for the hybrids with hydroxyl substitution. The new TAC-BF conjugates showed very good activity for AChE inhibition (sub-micromolar range) and good capacity for the inhibition of self- and Cu-mediated A beta aggregation, with dependence on the linker size and substituent groups of each main moiety. Neuroprotective effects were also found for the compounds through viability assays of neuroblastoma cells, after A beta(1-42) induced toxicity. Structure-activity relationship analysis provides insights on the best structural parameters, to take in consideration for future studies in view of potential applications in AD therapy.

Total Synthesis of Benzofuran-Based Aspergillusene B via Halogenative Aromatization of Enones

A novel non-aromatic pool synthetic strategy for the synthesis of benzofuran-based natural products via oxidative haloaromatization of enones is reported. This approach is successfully applied in the first total synthesis of the natural product aspergillusene B. In comparison with a separately executed aromatic pool synthesis, the non-aromatic pool protocol demonstrates equivalent efficiency but offers a much higher degree of modularity.

Chemical molecular-based approach to overcome multidrug resistance in cancer by targeting P-glycoprotein (P-gp)

Multidrug resistance (MDR) remains one of the major impediments for efficacious cancer chemotherapy. Increased efflux of multiple chemotherapeutic drugs by transmembrane ATP-binding cassette (ABC) transporter superfamily is considered one of the primary causes for cancer MDR, in which the role of P-glycoprotein (P-gp/ABCB1) has been most well-established. The clinical co-administration of P-gp drug efflux inhibitors, in combination with anticancer drugs which are P-gp transport substrates, was considered to be a treatment modality to surmount MDR in anticancer therapy by blocking P-gp-mediated multidrug efflux. Extensive attempts have been carried out to screen for sets of nontoxic, selective, and efficacious P-gp efflux inhibitors. In this review, we highlight the recent achievements in drug design, characterization, structure-activity relationship (SAR) studies, and mechanisms of action of the newly synthetic, potent small molecules P-gp inhibitors in the past 5 years. The development of P-gp inhibitors will increase our knowledge of the mechanisms and functions of P-gp-mediated drug efflux which will benefit drug discovery and clinical cancer therapeutics where P-gp transporter overexpression has been implicated in MDR.

1,2,3-Triazole-containing hybrids as leads in medicinal chemistry: A recent overview

The 1,2,3-triazole ring is a major pharmacophore system among nitrogen-containing heterocycles. These five-membered heterocyclic motifs with three nitrogen heteroatoms can be prepared easily using ‘click’ chemistry with copper-or ruthenium-catalysed azide-alkyne cycloaddition reactions. Recently, the ‘linker’ property of 1,2,3-triazoles was demonstrated, and a novel class of 1,2,3-triazole-containing hybrids and conjugates was synthesised and evaluated as lead compounds for diverse biological targets. These lead compounds have been demonstrated as anticancer, antimicrobial, anti-tubercular, antiviral, antidiabetic, antimalarial, anti-leishmanial, and neuroprotective agents. The present review summarises advances in lead compounds of 1,2,3-triazolecontaining hybrids, conjugates, and their related heterocycles in medicinal chemistry published in 2018. This review will be useful to scientists in research fields of organic synthesis, medicinal chemistry, phytochemistry, and pharmacology.

Commiphora myrrha Resin Alcoholic Extract Ameliorates High Fat Diet Induced Obesity via Regulation of UCP1 and Adiponectin Proteins Expression in Rats

This study was performed to evaluate anti-obesity potential of Commiphora myrrha resin ethanolic extract (CME) with the respect to expression of leptin, adiponectin and uncoupling protein 1 (UCP1) in rats. Control rats fed basal diet. Second group fed basal diet and administered CME (500 mg/kg bw) orally for 14 weeks. Third group fed high fat diet (HFD) for 14 weeks. Fourth group fed HFD and administered CME as second group. Fifth group fed HFD for 8 weeks then fed basal diet and administered CME as third group for another 6 weeks. Phytochemical analysis of CME identified the presence of germacrene B, 1,4-benzoquinone, benzofuran, hexadecanoic acid, 9,12-octadecnoic acid methyl ester, reynosin, 11, 14-eicosadienoic acid, isochiapin B, bisabolene epixod, elemene and 1-heptatriacotanol. High fat diet significantly increased food intake, body weight, hyperglycemia, serum levels of total cholesterol, triacylglycerol, low density lipoprotein and ketone bodies, AST and AST activities, concentration of malondialdehyde and histopathological changes in hepatic tissues. However, it significantly reduced serum levels of high density lipoprotein, leptin and adiponectin, activity of hepatic glutathione reductase (GR) and brown adipose tissue UCP1 protein expression. In contrast, CME ameliorated HFD increased body weight, hyperglycemia, dyslipidemia, ketonemia, hepatic tissues lipid peroxidation, restored hepatic tissue architecture and enhanced protein expression of leptin, adiponectin and UCP1 and activity of hepatic GR. This study indicated that CME ameliorated HFD induced hyperglycemia and dyslipidemia through normalization of HFD reduced leptin, adiponectin and UCP1 proteins production and antioxidant activity.

Comparative analysis of stilbene and benzofuran neolignan derivatives as acetylcholinesterase inhibitors with neuroprotective and anti-inflammatory activities

Stilbenes and benzofuran neolignans are important groups of plant phenolics therefore they play a significant role in plants and human health. The objective of this study was to investigate the structure-activity relationships of naturally occurring stilbene and benzofuran neolignan derivatives as acetylcholinesterase inhibitors. A series of these compounds were prepared and assessed for their inhibition on acetylcholinesterase activity. delta-Viniferin, pterostilbene trans-dehydrodimer, pallidol, grossamide, and boehmenan exerted acetylcholinesterase inhibitory potential. The several oligomeric compounds protected against cell damage resulting from t-BHP exposure and inhibited lipopolysaccharide/interferon-gamma (LPS/IFN gamma)-induced NO production in vitro. Our findings highlight the great potential of pterostilbene trans-dehydrodimer, pallidol, and boehmenan as multifunctional nutraceuticals for management of neurodegenerative diseases.
