Highly Efficient and Selective Electrochemical Synthesis of Substituted Benzothiophenes and Benzofurans in Microcontinuous Flow

A green and practical method for the synthesis of C-3 halogenated benzothiophenes and benzofurans from 2-alkynylthioanisoles or 2-alkynylanisoles and potassium halide was developed under transition-metal- and oxidant-free conditions, employing an assembled electrochemistry continuous-flow system. The carbon and platinum plates were used as the anode and cathode, respectively; KI or KBr not only served as a halogen source but also as an electrolyte. Moderate to good yields of C-3 halogenated benzothiophenes and benzofuran derivatives were obtained under constant current. Notably, the halogen could also be restored at the cathode to obtain C-3 dehalogenated benzothiophenes and benzofurans in high selectivity by adjusting the current and flow rate of the continuous-flow system. Moreover, this reaction could be easily scaled up with good efficiency in the continuous-flow system, which presents major advantages over reactions in a traditional batch.

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 174775-48-5, in my other articles.

Probing 2-acetylbenzofuran hydrazones and their metal complexes as alpha-glucosidase inhibitors

Inhibition of alpha-glucosidase is one of the important approaches in designing antidiabetic drugs for its role in decrease of the carbohydrates digestion to avoid post-prandial increase in blood sugar levels in diabetic patients. In the present study we designed a novel series of 2-acetylbenzofuran hydrazones (L1-L7) and their metal (II) complexes Cu (II), Co (II), Zn (II) and Mn (II) (8-29) and screened for inhibitory activity against the yeast alpha-glucosidase. The synthesis of hydrazones incorporated the use of I-2 as a catalyst which resulted in excellent yield of 94%. The ligand L3, showed good activity (IC50 = 47.51 +/- 0.86 mu M) while its metal complex (10) showed potent activity (IC50 = 1.15 +/- 0.001 mu M) compared to reference acarbose IC50 = 378.25 +/- 0.12 mu M. Similarly, the Cu (II) complexes with ligands L5 and L6 showed excellent alpha-glucosidase inhibition (IC50 = 0.15 +/- 0.003 12 and 0.21 +/- 0.002 mu M for 13, respectively) whereas, the metal complexes of Co (II), Mn (II), and Zn (II) showed moderate to poor inhibitory activities against alpha-glucosidase. The The findings are supported by the ligands and enzyme interactions through molecular docking studies. In conclusion, it is indicated that metal complexes of 2-acetylbenzofuran hydrazones have good potential for research leading to antidiabetic therapies.

Novel bis(pyrazole-benzofuran) hybrids possessing piperazine linker: Synthesis of potent bacterial biofilm and MurB inhibitors

Novel 1,4-bis[(2-(3-(dimethylamino)-1-oxoprop-2-en-1-yl)benzofuran-5-yl)methyl]piperazine was prepared and used as a key synthon for the this study. Therefore, 1,3-dipolar cycloaddition of this synthon with the appropriate hydrazonyl chlorides afforded a new series of bis(1,3,4-trisubstituted pyrazoles), linked via piperazine moiety. Furthermore, it reacted with hydrazine hydrate and phenyl hydrazine individually to afford the corresponding 1,4-bis[(2-(1H-pyrazolyl)benzofuran-5-yl)methyl]piperazines. Different bacterial strains and cell lines were selected to study the in-vitro antibacterial and cytotoxic activities for the new derivatives. 1,4-Bis[((2-(3-acetyl-1-(4-nitrophenyl)-1H-pyrazole-4-yl)carbonyl)benzofuran-5-yl)methyl]piperazine 5e showed the best anti-bacterial efficacies with MIC/MBC values of 1.2/1.2, 1.2/2.4 and 1.2/2.4 mu M against each of E. coli, S. aureus and S. mutans strains, respectively. In addition, the inhibitory activity of some new bis(pyrazoles) as MRSA and VRE inhibitors were studied. Compound 5e gave the best inhibitory activity with MIC/MBC values of 18.1/36.2, 9.0/18.1 and 18.1/18.1 mu M, respectively, against MRSA (ATCC:33591 and ATCC:43300) and VRE (ATCC:51575) bacterial strains, respectively. Compound 5e showed more effective biofilm inhibition activities than the reference Ciprofloxacin. It showed IC50 values of 3.0 +/- 0.05, 3.2 +/- 0.08 and 3.3 +/- 0.07 mu M against S. aureus, S. mutans and E. coli strains, respectively. Furthermore, experimental study showed excellent inhibitory activities of 1,4-bis[((2-(3-substituted-1-aryl-1H-pyrazole-4-yl)carbonyl)benzofuran-5-yl)methyl]piperazine derivatives, attached to p-NO2 or p-Cl groups, against MurB enzyme. Compound 5e gave the best MurB inhibitory activity with IC50 value of 3.1 mu M. The in-silico study was performed to predict the capability of new derivatives as potential inhibitors of MurB enzyme.

Prostaglandins Isolated from the Octocoral Plexaura homomalla: In Silico and In Vitro Studies Against Different Enzymes of Cancer

Prostaglandin A(2)-AcMe (1) and Prostaglandin A(2) (2) were isolated from the octocoral Plexaura homomalla and three semisynthetic derivatives (3-5) were then obtained using a reduction protocol. All compounds were identified through one- and two-dimensional (1D and 2D) nuclear magnetic resonance (NMR) experiments. Additionally, evaluation of in vitro cytotoxic activity against the breast (MDA-MB-213) and lung (A549) cancer cell lines, in combination with enzymatic activity and molecular docking studies with the enzymes p38 alpha-kinase, Src-kinase, and topoisomerase II alpha, were carried out for compounds 1-5 in order to explore their potential as inhibitors of cancer-related molecular targets. Results showed that prostaglandin A(2) (2) was the most potent compound with an IC50 of 16.46 and 25.20 mu g/mL against MDA-MB-213 and A549 cell lines, respectively. In addition, this compound also inhibited p38 alpha-kinase in 49% and Src-kinase in 59% at 2.5 mu M, whereas topoisomerase II alpha was inhibited in 64% at 10 mu M. Enzymatic activity was found to be consistent with molecular docking simulations, since compound 2 also showed the lowest docking scores against the topoisomerase II alpha and Src-kinase (-8.7 and -8.9 kcal/mol, respectively). Thus, molecular docking led to establish some insights into the predicted binding modes. Results suggest that prostaglandin 2 can be considered as a potential lead for development inhibitors against some enzymes present in cancer processes.

Synthetic enhancer compounds, besides acting on biogenic amine system, influence the glutamate transmission and stress response

Pharmaceutically available enhancer selegiline/(-)-deprenyl (DEP) in the clinically used dose shows antidepressant effect, but nothing is known about this effect in enhancer dose, and its effect on co-morbid anxiety. Moreover, data about the antidepressant/antianxiety effects of the serotonin-influencing enhancer, (2R)-1-(1-benzofuran-2-yl)-N-propylpentane-2-amine (BPAP) are also missing. The aim of the present paper is to establish the role of enhancer regulation in anxiety and follow the changes in the phosphorylation of glutamate subunits in prefrontal cortex as well as stress-related organ and hormonal changes as possible background mechanism. The effect of 3-week-treatment of rats with specific (0.001 mg/kg for DEP, 0.0001 mg/kg for BPAP) and non-specific (0.1 mg/kg for DEP, 0.05 mg/kg for BPAP) enhancer doses were evaluated on anxiety-like behavior in the elevated plus maze (EPM) and open-field (OF) tests. Phosphorylated glutamatergic GluR1 and GluN2B subunits were analyzed by Western blot. Changes in the stress-regulatory system were evaluated by measuring the organ weights and blood corticosterone concentrations. Non-specific enhancer doses had a tendency for anxiolysis on EPM, while only 0.1 mg/kg DEP elevated motility in OF. Specific enhancer doses significantly increased the expression of both glutamatergic receptor subunits; non-specific doses elevated only pGluR1. Treatments had no effects on stress-like organ weights; however, the specific enhancer doses significantly reduced the dark phase resting corticosterone levels. The study proved the enhancer-sensitivity of the glutamatergic transmitter system and suggested enhancer-induced stabilization of stress-hormone levels without major impact on non-stimulated anxiety-like behavior.

Formation of Polycyclic Aromatic Hydrocarbons (PAHs) and Oxygenated PAHs in the Oxidation of Ethylene Using a Flow Reactor

Interest in polycyclic aromatic hydrocarbons (PAHs) including a functional group in its chemical structure, particularly oxygenated PAHs (OPAHs), has been growing due to the toxicity and wide presence of the compound. Understanding the formation mechanism of OPAHs is very important for reducing their emission during combustion. However, studies on the quantitative evaluation of OPAHs have been very limited. In this study, the formation of OPAHs was quantitatively evaluated in addition to that of PAHs using a flow reactor system in which a mixture of ethylene, O-2, and N(2)reacted at atmospheric pressure. 5 types of OPAHs were targeted in this study: phenol, benzofuran, dibenzofuran, 9-fluorenone, and benzanthrone. 3 types of monocyclic aromatic hydrocarbons (MAHs) and 17 types of PAHs were also analyzed by gas chromatography mass spectrometry. Measurements were performed at different reaction gas temperatures (1050 to 1350 K), residence times (0.40 to 1.5 second), and equivalence ratios (3.0 to 12.0). Some measured data, mainly MAHs and PAHs, were compared with the concentrations predicted using existing kinetic models. Finally, we evaluated the reaction pathways that contributed to the formation of the OPAHs such as benzofuran, dibenzofuran, 9-fluorenone, and benzanthrone quantified in this study.
