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.

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.

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.

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.

Acyl radical to rhodacycle addition and cyclization relay to access butterfly flavylium fluorophores

Transition metal-catalyzed C-H activation and radical reactions are two versatile strategies to construct diverse organic skeletons. Here we show the construction of a class of flavylium fluorophores via the merge of radical chemistry and C-H activation starting from (hetero)aryl ketones and alkynes. This protocol is not only applicable to aryl ketones but also to heteroaryl ketones such as thiophene, benzothiophene and benzofuran, thus leading to structural diversity. Mechanism studies, including control experiments, intermediate separation, radical trapping, EPR and ESI-HRMS experiments, demonstrate that the key step lies in the addition of the acyl radical generated by the copper-catalyzed C-C bond cleavage of aryl ketone to the rhodacycle formed via the C-H activation of aryl ketone. The flavylium fluorophores feature butterfly symmetrical configuration, nearly planar skeleton and delocalized positive charge, and exhibit intriguing photophysical properties, such as tunable absorption and emission wavelengths and high quantum yields.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 497-23-4, in my other articles.

Substituted benzothiophene and benzofuran derivatives as a novel class of bone morphogenetic Protein-2 upregulators: Synthesis, anti-osteoporosis efficacies in ovariectomized rats and a zebrafish model, and ADME properties

The bone morphogenetic protein (BMP) pathway is a promising new target for the design of therapeutic agents for the treatment of low bone mass. This study optimized the structure of the anti-osteoporosis compound 38 by balancing its lipophilicity and improving its stability. Twenty derivatives which were not reported in the literature were designed and synthesized. The ovariectomized rat model of osteoporosis was selected to evaluate the therapeutic effects. Compound 125 showed better therapeutic efficacy than that of 38. We verified the anti-osteoporosis activity and BMP-2 protein upregulation after treatment with 125 in a zebrafish osteoporosis model. We found that 125 improved the ADME properties, therapeutic efficacy, and pharmacokinetics of the drug. Overall, we evaluated the anti-osteoporosis effects of the compounds of this type, preliminarily determined the target patient population, verified the mechanism of action, clarified the level of toxicity, and provided preliminary ADME data. We believe that these compounds can both correct bone loss that is already occurring in patients and have broad clinical applicability. (C) 2020 Elsevier Masson SAS. All rights reserved.

Modulation of benzofuran structure as a fluorescent probe to optimize linear and nonlinear optical properties and biological activities

The study presents the influence of structure modulation by introducing selected donor and acceptor substituents on optical properties of benzofuran used in biological imaging. As the starting form, 2-(5-formylbenzofuran-2-yl)acetamide described experimentally was used. This molecule contains an aldehyde group as reactive site, through which conjugation with protein occurs. Structure modulation was carried out by attaching additional electron-donating and electron-withdrawing substituents to the amino group, namely -NH2, -NHCH3, -NO2, -OH, and -OCH3. Studies have shown that the -NH2, -NHCH3, -OH, and -OCH(3)substituents do not induce a significant change in the position of maximum absorption and fluorescence relative to each other. They also do not change the parameters describing the nonlinear response. Only the presence of the -NO2 substituent results in significant solvatochromic shifts. Changing substituents also does not significantly affect the LD50 value, and all tested fluorescent probes should not be considered toxic to humans. Modulation of the benzofuran derivative structure also does not change the active center in which the biocomplex with the protein is formed. In each case, the conjugation takes place via LYS114. In addition, the study was prompted to analyze the linear and nonlinear optical properties of conjugates formed after the reaction with Concanavalin A.
