Study of Metal Ion Removal from Aqueous Systems Using Magnetic Nanostructures Based on Functionalized Poly(Benzofuran-co-Arylacetic Acid)

Metal pollution has become a worldwide problem, mainly because of the toxicity, effects on living organisms, and the impact on the food chain and the quality of drinking water. Researchers have been focusing on developing new materials through green chemistry methods in order to remove these pollutants from the environment. In the recent decades, due to their unique properties, magnetic nanostructures containing functionalized polymers as shells have been demonstrated to be useful in water and wastewater treatment for this application. In this study, we report the synthesis and characterization of hybrid magnetic core-shell nanostructures including magnetite as the inorganic core and poly(benzofuran-co-arylacetic acid) functionalized with N alpha, N alpha’-bis(carboxymethyl)-L-lysine as the organic shell. These nanomaterials were used in the adsorption of different metal ions from aqueous solutions and contaminated water samples collected from Rosia River (Rosia Montana, Romania), representing attractive alternatives for water and/or wastewater treatment. The properties of the magnetic hybrid nanostructures were investigated by Fourier-transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), magnetization measurements. The heavy metal concentrations in aqueous solutions were determined by flame atomic absorption spectrometry (FAAS).

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 66357-35-5 is helpful to your research. Product Details of 66357-35-5.

Ultrasound Assisted Synthesis of 2-Substituted Benzofurans via One-Pot and Sequential Method: Their In Vitro Evaluation

Background: The 2-substituted benzofuran framework has attracted enormous attention due to its presence in a range of bioactive compounds and natural products. While various methods for the synthesis of 2-substituted benzofuran derivatives are known, several of them suffer from certain drawbacks. Objective: The main objective of this work was to explore a series of 2-(het)aryl substituted benzofurans derivatives for their cytotoxic properties against cancer cell lines in vitro. Methods: In our efforts, we have developed a one-pot synthesis of this class of compounds via sequential C-C coupling followed by C-Si bond cleavage and subsequent tandem C-C/C-O bond-forming reaction under ultrasound irradiation. The methodology involved coupling of (trimethylsilyl)acetylene with iodoarenes in the presence of 10% Pd/C-Cul-PPh3-Et3N in MeOH followed by treating the reaction mixture with K2CO3 in aqueous WON and finally coupling with 2-iodophenol. A variety of 2-substituted benzofurans were synthesized using this methodology in good yield. All the synthesized compounds were tested in vitro against two cancer cell lines, e.g. MDAMB-231 and MCF-7 cell lines subsequently against SIRT1. Results: The benzofuran derivative 3m showed encouraging growth inhibition of both MDAMB-231 and MCF-7 cell lines and significant inhibition of SIRT1. The compound 3m also showed a concentration-dependent increase in the acetylation of p53. Conclusion: Our efforts not only accomplished a one-pot and direct access to 2-(het)aryl substituted benzofurans but also revealed that the benzofuran framework presented here could be a potential template for the identification of potent inhibitors of SIRT1.

Selective Quadruple C(sp(3))-F Functionalization of Polyfluoroalkyl Ketones

The significance of organofluorine compounds has inspired the establishment of numerousmethods for the functionalization of rather inert C-F bonds. Despite advances achieved in the manipulation of C(sp(2))-F bonds by employing transitionmetal catalysts, such as Pd, Rh, Cu, Ni, Ru, and Ir, strategies that address the paucity of effective pathways for selective activation of multiple C(sp(3))-F bonds remained challenging. In this context, we present an unprecedented coupling-aromatization-cyclization reaction of polyfluorinated ketones with diverse Nand S-nucleophiles that forms regiodefined perfluoroalkylated naphtho[1,2-b] furan/benzofuran derivatives by harnessing Co-promoted distinctive quadruple C(sp(3))-F bonds cleavage relay. This chemistry involving controlled and successive selective defluorination at heteronuclear centers would greatly contribute to the preparation of drug-like heterocycles as well as the late-stage elaboration of bio-relevant compounds. Controlled experiments and DFT theoretical studies revealed that the combination of cheap cobalt salt with Cs2CO3 enable expeditious C-F functionalization.

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 97148-39-5. Product Details of 97148-39-5.

Application of Electrochemical Processes to Classical Iodocyclisation: Utility for Selectivity and Mechanistic Insight

The hazards and difficulties of handling elemental halogens such as I-2 can be circumvented through the electrochemical generation of these species in situ and ‘on-demand’. Advantages of this approach include the halogen being introduced into the reaction mixture at a steady rate, ensuring low concentrations to prevent halogenation of reactive aromatic rings. We also demonstrate that the Lewis acid required to promote this reaction, a Zn(II) salt, can also be generated in situ from a zinc-coated graphite electrode in a clean and energy-efficient manner. Mechanistic studies indicate an unusual pathway, which provides selectivity for the iodocyclisation without the often-problematic electrophilic aromatic iodination of the aryl ring.

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.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 6296-53-3, you can contact me at any time and look forward to more communication. Formula: C10H7NO4.

Synthesis and biological evaluation of 1-(benzofuran-3-yl)-4-(3,4,5-trimethoxyphenyl)-1H-1,2,3-triazole derivatives as tubulin polymerization inhibitors

The key functions of microtubules and the mitotic spindle in cell division make them attractive targets for cancer therapy. In this study, a series of 1-(benzofuran-3-yl)-4-(3,4,5-trimethoxyphenyl)-1H-1,2,3-triazole derivatives was synthesized, and their antiproliferative activities against HCT116, HeLa, HepG2, and A549 cells were evaluated. 6-Methoxy-N-phenyl-3-(4-(3,4,5 trimethoxyphenyl)-1H-1,2,3-triazol-1-yebenzofuran-2-carboxamide (17g) exhibited the strongest antiproliferative activities, with IC50 values ranging from 0.57 to 5.7 mu M. Mechanistic studies showed that 17g inhibited tubulin polymerization, leading to the disruption of mitotic spindle formation, cell cycle arrest in the G2/M phase, and apoptosis of A549 cells. A docking study indicated that 17g was a good molecular fit at the colchicine binding site of tubulin. These results showed that 17g is a potential anticancer compound that is worthy of further development as a tubulin polymerization inhibitor.

Synthesis and Evaluation of Some Novel Essential Amino Acid-Benzofuran-Acetamide/Propanamide/Butanamide Hybrids as Potential Anticonvulsant Agents

In this study, some new essential amino acid-benzofuran-acetamide/propanamide/butanamide hybrid derivatives were synthesized. The structures of the synthesized compounds were confirmed on the basis of their elemental and spectral analyses. Their anti-seizure activity was investigated using maximal electroshock seizure (MES) and subcutaneous metrazol (scMET) seizure tests in mice. Neurotoxicity (NT) of the synthesized compounds was also determined by the rotarod test. Derivatives exhibited favorable protection in both MES and scMET tests with high safety levels in NT test. The derivatives have proven significant activity in mice and could be suggested as potential anticonvulsant lead compounds. All leucine-chlorobenzoyl benzofuran-acetamide/propanamide/butanamide hybrid derivatives (6b, 7b, and 8b) showed significant anticonvulsant activity in MES model.

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.
