Quantum chemical computational and spectroscopic (IR, Raman, NMR, and UV) studies on the 5-(5-methoxy-benzofuran-3-ylmethyl)-3H-[1,3,4] oxadiazole-2-thione

This research article describes the quantum chemical computational and spectroscopic (IR, Raman, NMR, and UV) studies on the 5-(5-methoxy-benzofuran-3-ylmethyl)-3H-[1, 3, 4] oxadiazole-2-thione (55MBOT). The research work is conducted in two levels. Initially, experimental FT-IR, FT-Raman, NMR (C-13, H-1) chemical shift and UV-Vis spectral data are recorded. After that, the theoretical computational analysis have been performed by DFT/B3LYP/6-311++G (d, p) basis level. The optimization of the 55MBOT is conducted to obtain the standard molecular structure. The theoretical FT-IR and FT-Raman wavenumbers obtained from the DFT/B3LYP/6-311++G (d, p) basis level and compared with experimental data. The detailed vibrational assignments are obtained with the help of potential energy distribution (PED). The experimental NMR chemical shifts are compared with computed NMR data. In addition, several analyses such as NBO, NLO, FMO MEP, Fukui function and thermodynamic properties have been conducted to determine the nature of the 55MBOT. (C) 2020 Elsevier B.V.

Ultrasonic-assisted micro solid phase extraction of arsenic on a new ion-imprinted polymer synthesized from chitosan-stabilized pickering emulsion in water, rice and vegetable samples

Pickering emulsion polymerization has been employed for the Ultrasonic assisted-micro solid phase extraction (UA-mu SPE) of ultra trace arsenic species by a new magnetic ion imprinted polymer (MIIP) prior to hydride generation atomic absorption spectrometry. 2-acetyl benzofuran thiosemicarbazone (2-ABT) as a new chelating agent and core- shell hydrophobic magnetic nanoparticles was synthesized and the polymerization was carried out at the presence of arsenic – ligand complex, crosslinker, monomer, initiator, stabilizing agent and water-oil emulsion magnetic carrier. In second step, the nanoparticles and polymers were characterized. The analytical parameters such as pH, amount of polymer and ultrasonic time were selected and optimozed by Plackett-Burman and Box-Behnken designs respectively. Linear dynamic range, detection limit and relative standard deviation were 0.01-85.000 mu g.L-1, 0.003 mu g.L-1, and 3.21%, respectively. The proposed preconcentration procedure was successfully applied to the determination of arsenic ion in a wide range of food samples with different and complex matrixes.

Amidino-Rocaglates: A Potent Class of eIF4A Inhibitors

Rocaglates share a common cyclopenta[b]benzofuran core that inhibits eukaryotic translation initiation by modifying the behavior of the RNA helicase, eIF4A. Working as interfacial inhibitors, rocaglates stabilize the association between eIF4A and RNA, which can lead to the formation of steric barriers that block initiating ribosomes. There is significant interest in the development and expansion of rocaglate derivatives, as several members of this family have been shown to possess potent anti-neoplastic activity in vitro and in vivo. To further our understanding of rocaglate diversity and drug design, herein we explore the RNA clamping activity of >200 unique rocaglate derivatives. Through this, we report on the identification and characterization of a potent class of synthetic rocaglates called amidino-rocaglates. These compounds are among the most potent rocaglates documented to date and, taken together, this work offers important information that will guide the future design of rocaglates with improved biological properties.

Metal-Free Tandem Rearrangement/Lactonization: Access to 3,3-Disubstituted Benzofuran-2-(3H)-ones

A novel metal-free synthesis of 3,3-disubstituted benzofuran-2-(3H)-ones through reacting alpha-aryl-alpha-diazoacetates with triarylboranes is presented. Initially, triarylboranes were successfully investigated in alpha-arylations of alpha-diazoacetates, however in the presence of a heteroatom in the ortho position, the boron enolate intermediate undergoes an intramolecular rearrangement to form a quaternary center. The intermediate cyclizes to afford valuable 3,3-disubstituted benzofuranones in good yields.

The psychoactive aminoalkylbenzofuran derivatives, 5-APB and 6-APB, mimic the effects of 3,4-methylenedioxyamphetamine (MDA) on monoamine transmission in male rats

Rationale The nonmedical use of new psychoactive substances (NPS) is a worldwide public health concern. The so-called benzofury compounds, 5-(2-aminopropyl)benzofuran (5-APB) and 6-(2-aminopropyl)benzofuran (6-APB), are NPS with stimulant-like properties in human users. These substances are known to interact with monoamine transporters and 5-HT receptors in transfected cells, but less is known about their effects in animal models. Methods Here, we used in vitro monoamine transporter assays in rat brain synaptosomes to characterize the effects of 5-APB and 6-APB, together with theirN-methyl derivatives 5-MAPB and 6-MAPB, in comparison with 3,4-methylenedioxyamphetamine (MDA) and 3,4-methylenedioxymethamphetamine (MDMA). In vivo neurochemical and behavioral effects of 5-APB (0.3 and 1.0 mg/kg, i.v.) and 6-APB (0.3 and 1.0 mg/kg, i.v.) were assessed in comparison with MDA (1.0 and 3.0 mg/kg, i.v.) using microdialysis sampling in the nucleus accumbens of conscious male rats. Results All four benzofuran derivatives were substrate-type releasers at dopamine transporters (DAT), norepinephrine transporters (NET), and serotonin transporters (SERT) with nanomolar potencies, similar to the profile of effects produced by MDA and MDMA. However, the benzofurans were at least threefold more potent than MDA and MDMA at evoking transporter-mediated release. Like MDA, both benzofurans induced dose-related elevations in extracellular dopamine and serotonin in the brain, but benzofurans were more potent than MDA. The benzofuran derivatives also induced profound behavioral activation characterized by forward locomotion which lasted for at least 2 h post-injection. Conclusions Overall, benzofurans are more potent than MDA in vitro and in vivo, producing sustained stimulant-like effects in rats. These data suggest that benzofuran-type compounds may have abuse liability and could pose risks for adverse effects, especially if used in conjunction with abused drugs or medications which enhance monoamine transmission in the brain.

The role of amiodarone in contemporary management of complex cardiac arrhythmias

Amiodarone is an iodinated benzofuran derivative, a highly lipophilic drug with unpredictable pharmacokinetics. Although originally classified as a class III agent due to its ability to prolong refractoriness in cardiac regions and prevent/terminate re-entry, amiodarone shows antiarrhythmic properties of all four antiarrhythmic drug classes. Amiodarone is a potent coronary and peripheral vasodilator and can be safely used in patients with left ventricular dysfunction after myocardial infarction or those with congestive heart failure or hypertrophic cardiomyopathy. Its use is regularly accompanied with QT and QTc-interval prolongation but rarely with ventricular proarrhythmia. It is the most powerful pharmacological agent for long-term sinus rhythm maintenance in patients with atrial fibrillation. Amiodarone, particularly if co-administered with beta-blockers, reduces the rate of arrhythmic death due to ventricular tachyarrhythmias in patients with heart failure, but its benefit on cardiovascular and overall survival in these patients is uncertain. In addition, amiodarone is an important adjuvant drug for the reduction of shocks in patients with an implantable cardioverter-defibrillator. Over the past 40 years, amiodarone became the most prescribed antiarrhythmic. Nevertheless, the slow onset of its antiarrhythmic action requires a loading dose while the high risk of non-cardiac toxicity and common drug-drug interactions limit its long-term use. Furthermore patients treated with amiodarone require a close supervision by the treating physician. Therefore amiodarone is generally considered a secondary therapeutic option. Long-term treatment with amiodarone should be based on the use of minimal doses for satisfactory arrhythmia outcome and serial screening for thyroid, liver and pulmonary toxicity.

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 66357-35-5. Recommanded Product: Ranitidine.
