Abstract:

The quinoxaline derivatives are beneficial compounds because of their various medicinal and industrial applications. They are well-known for application in organic light emitting devices, polymers and pharmaceutical agents. The quinoxaline-containing polymers are applicable in optical devices due to their thermal stability and low band gap. There are many reported procedures for the synthesis of bis- and polyquinoxalines and quinoxaline-containing macrocycles. The quinoxaline-based compounds as fascinating structures are important subjects of interest in either basic or applied sciences. This review summarizes the latest progresses related to the quinoxalines, quinoxaline-containing macrocycles, and bis- and poly quinoxalines, including the synthesis, functionalization and modification methods and applications of these compounds.

Abstract:

There has been substantial research undertaken on the role of green synthesized corrosion inhibitors as a substantial approach to inhibit the corrosion of metals and their alloys in acidic environments. Herein, electrochemical studies, surface characterization, and theoretical modeling were adopted to investigate the corrosion inhibition proprieties of novel synthesized quinoxaline derivatives bearing 8-Hydroxyquinoline, namely 1-((8-hydroxyquinolin-5-yl) methyl)-3,6-dimethylquinoxalin-2(1H)-one (Q1) and 1-((8-hydroxyquinolin-5-yl)methyl) quinoxalin-2(1H)-one (Q2) on mild steel corrosion in 1 mol/L HCl solution. The principal finding of this research was that both inhibitors acted as good corrosion inhibitors with Q1 having the highest performance (96% at 5 × 10−3 mol/L). Electrochemical results obtained via potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) techniques demonstrated that quinoxaline compounds belonged to mixed-type inhibitors; their presence significantly increased the polarization resistance, preventing simultaneously anodic and cathodic reactions. Further, experimental results provided preliminary insights about the interactions mode between studied molecules and the mild steel surface, which followed the Langmuir adsorption model, and physical and chemical interactions assisted their inhibition mechanism. Besides, SEM analyses confirmed the existence of protective film on the metal surface after the addition of 5 × 10−3 mol/L of quinoxalines. In addition, the temperature and immersion time effects on inhibition performances of quinoxalines were investigated to evaluate their performances in different operating conditions. Besides, Density Functional Theory (DFT) and molecular dynamics (MD) simulations were carried out to explore the most reactive sites of quinoxaline inhibitors and their interaction mechanism. Theoretical results revealed that the inhibitor molecule with additional electron-donating functional group strongly interacted with the steel surface.

Abstract:

We report a suitable quinoxaline synthesis using molybdophosphovanadates supported on commercial alumina cylinders as catalysts. These catalysts were prepared by incipient wetness impregnation. The catalytic test was performed under different reaction conditions in order to know the performance of the synthesized catalysts. The method shows high yields of quinoxaline derivatives under heterogeneous conditions. Quinoxaline formation was obtained using benzyl,o-phenylenediamine, and toluene as reaction solvent at room temperature. The CuH2PMo11VO40supported on alumina showed higher activity in the tested reaction. Finally, various quinoxalines were prepared under mild conditions and with excellent yields.

Full text

Abstract:

The work reported is divided into two parts: fIrstly a section dealing with the preparation of some novel diazanaphthoquinones and their reactions, especially the Diels-Alder reaction, and secondly an account of some quinoxaline derivatives and their fluorescence properties. Quinoxaline quinones containing electron-donating groups at both the 2- and 3- position have shown a difference in their stability and their behaviour in the Diels-Alder reaction compared to the stability and the reactions of quinoxaline quinone. Symmetrical dienes in the Diels-Alder reaction yielded the initial addition products, which were resistant to oxidation, whereas unsymmetrical dienes produced fully aromatized products. Crown ether derivatives of 5,8-dimethoxyquinoxaline and the corresponding quinoxaline quinones were prepared. An improved method for the preparation of a fluorescent derivatising reagent is described. This compound was then used to prepare ion-responsive fluoroionophores containing monoazacrown ethers of different cavity sizes. The complexation of these fluoroionophores, in dichloromethane, was achieved by using perchlorates of alkali and alkaline earth metals. A strong correlation between the size of the metal ion and the cavity size of the crown ether was seen in the fluorescence quantum yields of the complex, and a fluoroionophore containing a diazacrown ether gave particularly noteworthy results. A bathochromic shift with a strong hyperchromic effect was the most important feature caused by complexation with metal ions for these fluoroionophores. Fluorescent open chain ethers (podands) were also prepared and their complexation with metal ions was studied. A strong bathochromic shift and a hypochromic effect was observed especially in their excitation spectra. A further novel fluorescent derivatising reagent was prepared by extending the conjugated system. This gave the expected improved results upon the preparation of the derivatives including fluoroionophores having crown ethers of different cavity sizes. However, the changes in fluorescence did not correlate with the relationship between the sizes of the metals ion and the cavity of the crown ether. Nevertheless, a large bathochromic shift was observed on complexation with metal ions.

Dissertação para obtenção do Grau de Doutor em Química Sustentável
Antimicrobial agents have revolutionized medicine and promoted an increase in average life expectancy of human populations worldwide. These drugs are used not only in human medicine but also in veterinary practice, in the treatment and prevention of infections, and in some regions in the world, as well as growth promoters, ensuring a greater and better animal production. The use of antimicrobial agents in animal production causes contamination of the final product with drug residues that are eventually distributed in human food chain. Residues of antimicrobial agents provenient from human and animal consumption are also present in sewage, surface water or ground water. It is still unknown all the consequences of this contamination, but there are indications of changes in indigenous microbiota. The use of these drugs was quickly followed by the emergence of resistance, which led to decreased efficacy and compounds available. Therefore, the spread of antimicrobial agents in the environment is also associated with increased resistance to such drugs. The presented work intended to establish methods for monitoring the presence of antibiotics in animal foods, evaluate if the presence of antimicrobial agents in the environment at sub-inhibitory concentrations can contribute to the selection of resistant bacteria and characterize the biological activity of a number of compounds of the quinoxaline family as potential new antimicrobial agents. In order to achieve these objectives, chromatographic techniques were used for detection and quantification of antimicrobial agents, methods of microbiology and molecular biology to evaluate the behavior of bacteria under selective pressure. Various strains of prokaryotes and eukaryotes microorganisms were also used to evaluate the antimicrobial activity of N-oxide derivatives of quinoxaline. We used, also, cell cultures to assess the potential toxicity of these new antibiotics. A new chromatographic method was developed to quantify the reduced and oxidized forms of glutathione, in order to infer the cellular oxidative stress induced by exposure to the quinoxaline derivative compounds with proven antimicrobial activity. The results confirm that the chromatographic HPLC-DAD methods are powerful tools in monitoring food quality. They also indicate that the presence of subinhibitory amounts of ciprofloxacin in water may influence the dynamic of susceptible and resistant to ciprofloxacin Escherichia coli population. An assessment of the biological activity of quinoxaline derivatives indicated the compounds studied as potential new antimicrobial agents who have shown low toxicity in cell lines and oxidative cell damage in small extent.

Abstract:

Quinoxaline-functionalized, cage-annulated oxa- and thiacrown ethers have been synthesized as possible specific metal host systems. The synthesis and characterization of quinoxaline-functionalized, cage-annulated oxa- and thiacrown ethers have been described. The characterization of these host systems have been fully achieved in solution by using various techniques such as IR, 1H NMR, and 13C NMR spectroscopic methods, high-resolution mass spectrometry (HRMS), elemental microanalysis, and X-ray crystallographic analysis in case of one quinoxaline-functionalized, cage-annulated oxacrown ether compound. The synthesis of the diphosphine ligand 2,3-bis(diphenylphosphino)-N-p-tolylmaleimide (bmi) is described. The substitution of the MeCN ligands in the activated cluster 1,2-Os3(CO)10(MeCN)2 by the diphosphine ligand bmi proceeds rapidly at room temperature to furnish a mixture of bridging and chelating Os3(CO)10(bmi) isomers and the ortho-metalated product HOs3(CO)9[μ-(PPh2)C=C{PPh(C6H4)}C(O)N(tolyl-p)C(O)]. Thermolysis of the bridging isomer 1,2-Os3(CO)10(bmi) under mild conditions gives the chelating isomer 1,1-Os3(CO)10(bmi), whose molecular structure has been determined by X-ray crystallography. The kinetics for the ligand isomerization have been investigated by UV-vis and 1H NMR spectroscopy in toluene solution over the temperature range of 318-348 K. On the basis of kinetic data conducted in the presence of added CO and the Eyring activation parameters, a non-dissociative phosphine migration across one of the Os-Os bonds is proposed. Orthometalation of one of the phenyl groups associated with the bmi ligand is triggered by near-UV photolysis of the chelating cluster 1,1- Os3(CO)10(bmi).

The redox properties of two quinoxaline derivatives, brimonidine and varenicline, previously studied electrochemically, were evaluated by performing a computational study. On the basis of some useful quantum chemical parameters the differences and similarities between their redox features were explained. The obtained results support the experimental findings that the redox processes of both compounds are under strong influence of the solution pH, whereas the reduction of brimonidine occurs easier than the reduction of varenicline, at corresponding pH values.
