Structural Requirements of Benzofuran Derivatives Dehydro-delta- and Dehydro-epsilon-Viniferin for Antimicrobial Activity Against the Foodborne Pathogen Listeria monocytogenes

In a recent study, we investigated the antimicrobial activity of a collection of resveratrol-derived monomers and dimers against a series of foodborne pathogens. Out of the tested molecules, dehydro-delta-viniferin and dehydro-epsilon-viniferin emerged as the most promising derivatives. To define the structural elements essential to the antimicrobial activity against the foodborne pathogen L. monocytogenes Scott A as a model Gram-positive microorganism, the synthesis of a series of simplified benzofuran-containing derivatives was carried out. The systematic removal of the aromatic moieties of the parent molecules allowed a deeper insight into the most relevant structural features affecting the activity. While the overall structure of compound 1 could not be altered without a substantial loss of antimicrobial activity, the structural simplification of compound 2 (minimal inhibitory concentration (MIC) 16 mu g/mL, minimal bactericidal concentration (MBC) >512 mu g/mL) led to the analogue 7 with increased activity (MIC 8 mu g/mL, MBC 64 mu g/mL).

Structural, spectroscopic and computational investigations on (4,6-dimethyl-benzofuran-3-yl)-acetic acid hydrazide

The present work investigates structural and spectroscopic characteristics of (4,6-dimethyl-benzofuran-3-yl)-acetic acid hydrazide (4DBAH) through different spectroscopic methods (Infrared, Raman, and NMR) and quantum chemical computations. The quantum chemical computations are done with adequate level of theory using B3LYP from density functional with 6-311++G(d,p) basis set. Conformational analysis is performed to identify the structure corresponding to local minima and local maxima from the potential energy surface (PES).The theoretically simulated and Raman wavenumbers are compared with experimental data. The complete wavenumber assignments are accomplished by the potential energy distribution (PED) of individual vibrational modes. The experimental H-1 and C-13 NMR chemical shifts are investigated and then compared with computed NMR data. The AIM and NCI analysis gives more insights into the nature of different types of interactions, both attractive and repulsive nature present in the molecule. In addition, several analyses such as NBO, NLO, FMO, MEP and thermodynamic properties have also been conducted to determine the nature of the 4DBAH. (C) 2020 Published by Elsevier B.V.

Organocatalytic Gram-Scale Synthesis and Alkylation of Heteroaryl and Electron-Rich Aryl alpha-Substituted gamma-Lactones

The synthesis of gamma-lactones alpha-substituted with heterocycles and electron-rich aromatic rings is described. The method, based on a sequence involving an organocatalytic addition of boronic acid to the 5-hydroxyfuran-2(5H)-one, followed by reduction and lactonization, gives access to broad range of gamma-lactones on a gram scale. Among these, gamma-lactones bearing a benzofuran, a benzothiophene, and an indole ring were alkylated in mild catalytic conditions to construct alpha-quaternary stereocenters. Interesting mild oxidation reaction, using molecular oxygen, was also highlighted during this study.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 66357-35-5, you can contact me at any time and look forward to more communication. Quality Control of Ranitidine.

Recent Updates on Anti-Inflammatory and Antimicrobial Effects of Furan Natural Derivatives

The furan nucleus is found in a large number of biologically active materials. In recent years, many natural furan derivatives were isolated and their biological effects were investigated. In this review, we focused on the anti-inflammatory and antimicrobial effects of some natural furans and discussed their effects on the immune system. Our investigation revealed that furan natural derivatives have effective antioxidant activities and exert regulatory effects on various cellular activities by modifying some signaling pathways such as MAPK (mitogen-activated Protein Kinase) and PPAR-gamma (peroxisome proliferator-activated receptor gamma). The antimicrobial activity of these natural compounds was performed through selective inhibition of microbial growth and modification of enzymes. Further studies are needed for isolation and detection of different furan derivatives from natural compounds and investigation of their precise mechanisms for revealing health beneficial effects of these compounds.

Cs2CO3-Mediated Rapid Room-Temperature Synthesis of 3-Amino-2-aroyl Benzofurans and Their Copper-Catalyzed N-Arylation Reactions

Cs2CO3 in dimethylformamide (DMF) is a perfect combination for the rapid room-temperature synthesis of 3-amino-2-aroyl benzofuran derivatives from the reaction of 2-hydroxybenzonitriles and 2-bromoacetophenones in good to excellent yields. Using this one-pot C-C and C-O bond-forming strategy, we prepared a series of 3-amino-2-aroyl benzofuran derivatives within a very short time (10-20 min). This method was also found suitable for gram-scale synthesis. Benzofurans (3) obtained by this Cs2CO3-mediated methodology were then further explored for the development of a tunable base- and ligand-free copper-catalyzed N-arylation methodology using arylboronic acids for the easy access of either mono- or bi-N-aryl derivatives of aminobenzofurans at ambient temperature. The reaction of 3 with malononitrile in DMF medium under microwave heating conditions provided highly fluorescent conjugated alkenes and novel pyridine-fused benzofurans.

Novel Meroterpenoids from Hypericum patulum: Highly Potent Late Na(v)1.5 Sodium Current Inhibitors

Hypulatones A and B (1 and 2), two racemic meroterpenoids possessing an unprecedented spiro[benzofuran-2,1′-cycloundecan]-4′-ene-4,6(5H)-dione core, were characterized from Hypericum patulum. Compound 2 was found to significantly inhibit the late current of Na(v)1.5 (late I-Na, IC50 = 0.2 mu M). Importantly, 2 exhibited remarkable separation (>100-fold) of late I-Na relative to peak I-Na and notable selectivity over Ca(v)3.1, K(v)1.5, and hERG. 1 showed comparable inhibition on late I-Na compared to that of 2 with poorer selectivity.
