Synthesis, characterization and spectroscopic investigation of N-(2-acetylbenzofuran-3-yl)acrylamide monomer: Molecular structure, HOMO-LUMO study, TD-DFT and MEP analysis

In this study, a novel acrylamide monomer was synthesized and characterized by UV-Vis, FT-IR and H-1 NMR measurements. The acrylamide monomer namely, N-(2-acetyl-benzofuran-3-yl)acrylamide (NABA), was prepared in two steps. In the first step, 1-(3-aminobenzofuran-2-yl)ethan-1 -one was synthesized by the reaction of 1-chloroacetone with 2-hydroxy-benzonitrile under basic conditions. In the second step, the obtained 1-(3-aminobenzofuran-2-yl)ethan-1 -one was reacted with acryloyl chloride and triethylamine at 0-5 degrees C temperature for obtaining NABA monomer. Then, the structural, vibrational, nuclear magnetic resonance and electronic properties for the synthesized monomer were determined by quantum chemical calculations of DFT method. The results were compared with experimental FT-IR, H-1 NMR and UV-Vis spectral data. The band gap of HOMO and LUMO show that the NABA monomer is chemically active and has charge transfer within the monomer. Moreover, molecular electrostatic potential (MEP) maps were drawn to identify reactive regions of NABA monomer. (C) 2019 Elsevier B.V. All rights reserved.

New negative dielectric anisotropy liquid crystals based on benzofuran core

In this paper, new liquid crystal compounds with negative dielectric anisotropy were synthesised by regulating the substituents on the benzofuran ring. Their structures were confirmed by(1)H-nuclear magnetic resonance,(CNMR)-C-13 and mass spectra. The effects of substituent on the properties of liquid crystals were investigated. Compared with the reference compounds, the compounds with 5-ethoxy-6,7-difluorobenzofuran ring exhibit higher clearing points as well as the tendency of expansion of SmA phase range. The density functional theory calculation results reveal that the 6-ethoxy-7-fluorobenzofuran-based compound has smaller aspect ratio than that of the 5-ethoxy-6,7-difluorobenzofuran-based compound, which results in the diminish of the mesophase. Although the dielectric anisotropy of the 5-ethoxy-6,7-difluorobenzofuran-based compound is slightly lower than that of the reference compound, it has both the largest perpendicular and parallel dielectric constant.

Site-selective remote C(sp(3))-H heteroarylation of amides via organic photoredox catalysis

Radical translocation processes triggered by nitrogen-centered radicals (NCRs), such as 1,5-hydrogen atom transfers (1,5-HAT), demonstrated by the well-established Hofmann-Loffler-Freytag (HLF) reaction, provide an attractive approach for the controllable and selective functionalization of remote inert C(sp(3))-H bonds. Here we report an amidyl radical-triggered site-selective remote C(sp(3))-H heteroarylation of amides under organic photoredox conditions. This approach provides a mild and highly regioselective reaction affording remote C(sp(3))-H heteroarylated amides at room temperature under transition-metal free, weakly basic, and redox-neutral conditions. Non-prefunctionalized heteroarenes, such as purines, thiazolopyridines, benzoxazole, benzothiazoles, benzothiophene, benzofuran, thiazoles and quinoxalines, can be alkylated directly. Sequential and orthogonal C-H functionalization of different heteroarenes by taking advantage pH value or polarity of radicals has also been achieved. DFT calculations explain and can predict the site-selectivity and reactivity of this reaction. This strategy expands the scope of the Minisci reaction and serves as its alternative and potential complement.

Evaluation of Synthesized Ester or Amide Coumarin Derivatives on Aromatase Inhibitory Activity

Aromatase inhibitors are effective for the treatment of diseases such as breast cancer, which has led to an increase in their demand. However, only a limited number of aromatase inhibitor drugs are currently being marketed. In addition, considering the important aspect of drug resistance, the development of newer drug types is required. We have been developing inhibitors with backbone structures that differ from existing aromatase inhibitors. In this regard, we previously reported that diethylaminocoumarin dimers and thiazolyl coumarin derivatives possess strong aromatase inhibiting capabilities. In this study, we further examined the structure activity relationships of coumarin derivatives synthesized from thiazolyl coumarin derivatives and their aromatase inhibiting capabilities. Consequently, amide coumarin N-benzhydry1-7-(diethylamino)2-oxo-2H-chromene-3-carboxamide (IC50 values 4.5 mu M) is inhibitor of aromatase. This inhibitor was found to be comparable aromatase inhibitory activity to the 1st generation aromatase inhibitor aminoglutethimide (3.2 mu M). Substitution of the amide group on the amide coumarin derivative affects the aromatase inhibiting activity. Our findings suggest that the structure of each substituent changes the orientation of the compound in the active site of aromatase, thus creating a difference in their activities.

Bioactive Potential of 2-Methoxy-4-vinylphenol and Benzofuran from Brassica oleracea L. var. capitate f, rubra (Red Cabbage) on Oxidative and Microbiological Stability of Beef Meat

In the future, plant based phytochemicals will be considered as efficient replacement sources of chemical preservatives, to act as potential bio-preservatives. We investigated the antibacterial and antioxidant activity of red cabbage (RC) extracts using different solvents. Among all extracts, chloroform extract exhibited strong antimicrobial and antioxidant activities. Hence, the phytochemical constitutions of the RC chloroform extract was examined by GC-MS analysis, and further, based on molecular docking analysis, revealed 2-Methoxy-4-vinylphenol and benzofuran as two major compounds found to be possessing higher degrees of interaction with DNA gyrase (4PLB; -8.63 Kcal.mol(-1)) and lipoprotein (LpxC-8.229 Kcal.mol(-1)), respectively, of the bacterial cell wall, which leads to higher antimicrobial efficacy. Further, it was confirmed with that the in vivoCaenorhabditis elegansmodel (but no cytotoxic effect) was exhibited in the MCF-7 cell line. Thus, we investigated the influence of this extract on the shelf life of meat under refrigeration storage. The physicochemical properties were observed periodically, and microbial analysis was conducted. The shelf life of the beef was enhanced (up to eight days) in terms of microbial and physiochemical properties, at 4 +/- 2 degrees C when compared to control. We concluded that chloroform extract of RC has potential as a natural preservative in the meat processing industry.

Amino acids conjugated quinazolinone-Schiff’s bases as potential antimicrobial agents: Synthesis, SAR and molecular docking studies

A series of amino acids conjugated quinazolinone-Schiff’s bases were synthesized and characterized by analytical and spectroscopic methods. All the synthesized analogues (8-43) and the intermediates (1-7) were screened for their in vitro antibacterial and antifungal activities. In antimicrobial activity, compounds 12-16, 21-25, 30-34 and 39-43 showed excellent antibacterial activity which is better than the antibacterial standard Streptomycin. Compounds 15, 23-25, 30-34, 36 and 38-43 showed excellent antifungal activities which is more active than the reference antifungal drug Bavistin. Further, to understand the correlation of biological activity with that of drug-receptor interaction, molecular docking was performed on active site ofglucosamine-6-Phosphate (GlcN-6-P) synthase (PDB ID: 2VF5) which showed good binding profile. Molecular docking studies and Preliminary structure-activity (SAR) relationship revealed that the tryptophan and phenylalanine conjugated quinazolinones with electron donating groups (OH and OCH3) were found to be excellent antimicrobial activities which is better than the glycine and alanine conjugated derivatives. This may be explained by the contribution of aromaticity and hydrophobicity of amino acids. Among the series, compounds 41 and 43 showed the highest docking scores for antimicrobial activity. The conjugation plays a major role in improving the biological activities of those compounds.

OH-Initiated Reactions of para-Coumaryl Alcohol Relevant to the Lignin Pyrolysis. Part II. Kinetic Analysis

Monolignols are precursor units and primary products of lignin pyrolysis. The currently available global (lumped) and semidetailed kinetic models, however, are lacking the comprehensive decomposition kinetics of these key intermediates in order to advance toward the fundamentally based detailed chemical-kinetic models of biomass pyrolysis. para-Coumaryl alcohol (HOPh-CH=CH-CH2OH, p-CMA) is the simplest of the three basic monolignols containing a typical side-chain double bond and both alkyl and phenolic type OH groups. The two other monomers additionally contain one and two methoxy groups, respectively, attached to the benzene ring. Previously, we developed a detailed fundamentally based mechanism for unimolecular decomposition of p-CMA (as well as its truncated allyl and cinnamyl alcohol models) and explored its reactivity toward H radicals generated during pyrolysis. The reactions of p-CMA with pyrolytic OH radicals is another set of key reactions particularly important for understanding the formation mechanisms of a wide variety of oxygenates in oxygen-deficit (anaerobic) conditions and the role of the lignin side groups in pyrolysis pathways. In Part I of the current study (J. Phys. Chem. A, 2019, 123, 2570-2585), we reported a detailed potential energy (enthalpy) surface analysis of the reaction OH + p-CMA with suggestions for a variety of chemically activated, unimolecular, and bimolecular reaction pathways. In Part II of our work, we provide a detailed kinetic analysis of the major reaction channels to evaluate their significance and possible impacts on product distributions. Temperature- and pressure-dependent rate constants are calculated using the quantum Rice-Ramsperger-Kassel method and the master equation analysis for falloff and stabilization. Enthalpies of formation, entropies, and heat capacities are calculated using density functional theory and higher-level composite methods for stable molecules, radicals, and transition-state species. A significant difference between well depths for the chemically activated adduct radicals, [p-CMA-OH]*, is found for the alpha- and beta-carbon addition reactions to generate the 1,3- and 1,2-diol radicals, respectively. This is due to the synergistic effect from conjugation of the proximal radical center with the aromatic ring and the strong H-bonding interaction between vicinal OH groups in the beta-adduct (1,2-diol radical). Both adducts undergo isomerization and low-energy transformations, however, with different kinetic efficiencies because of the difference in stabilization energies. Reaction pathways include dissociation, intramolecular abstraction, atom and group transfers, and elimination. Of particular interest is a roaming-like low-energy dehydration reaction to form O-centered intermediate radicals. The kinetic analysis demonstrated the feasible formation of various products detected in pyrolysis experiments, suggesting that the gas-phase reactions of OH radicals can be a key process to form major products and complex oxygenates during lignin pyrolysis. Our preliminary experiments involving pyrolysis of the vaporized monomers support this basic statement. A novel mechanism for the formation of benzofuran, identified in experimentation, is also provided based on the potential conversions of hydroxyphenylacetaldehyde and corresponding isomers, which are kinetically favored products.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 6296-53-3. Product Details of 6296-53-3.
