A series of novel V-shaped quinoxaline, [1,2,5]oxadiazolo[3,4-
The synthetic approach based on a sequence of Buchwald–Hartwig cross-coupling and annulation through intramolecular oxidative cyclodehydrogenation has been used for the construction novel 4-alkyl-4H-thieno[2′,3′:4,5]pyrrolo[2,3-b]quinoxaline derivatives. For first time, these polycyclic compounds were evaluated antimycobacterial activity, including extensively drug-resistant strains. A reasonable bacteriostatic effect against Mycobacterium tuberculosis H37Rv was demonstrated. plausible...
In this paper, we present an original approach for the voltammetric determination of antibiotic chloramphenicol on a glassy carbon electrode modified with nanotubes and electrodeposited layer based 3,6‐diethynyl‐9H‐carbazole used as molecular recognition agent. The analytical signal was detected by electrochemical reduction current analyte using differential pulse voltammetry. nature intermolecular interaction studied absorption fluorescence spectroscopy, well high‐performance liquid...
The well-known fluorophore, namely 1,3,6,8-tetrakis[(trimethylsilyl)ethynyl]pyrene, has been studied profoundly as a fluorescent sensor toward nitroaromatic compounds in solutions and vapor phase. Three prototypes of materials for sensing were prepared via electrospinning drop-casting onto the melamine formaldehyde foam with fluorophore pure solid or dopant polystyrene matrix. It shown that this based on it have high detection limits within range 10−8 to 10−9 M acetonitrile solution up ppb...
New donor–π–acceptor pyrimidine-based dyes comprising an amide moiety as anchoring group have been designed. The were synthesized by sequential procedures based on the microwave-assisted Suzuki cross-coupling and bromination reactions. influence of dye structure length π-linker photophysical electrochemical properties photovoltaic effectiveness dye-sensitized solar cells was investigated. An increase in efficiency with a decrease revealed. D1 only one 2,5-thienylene-linker provided highest...
Five random copolymers comprising styrene and with pendant fluorophore moieties, namely pyrene, naphthalene, phenanthrene, triphenylamine, in molar ratios of 10:1, were synthesized employed as fluorescent sensors. Their photophysical properties investigated using absorption emission spectral analyses dichloromethane solution solid state. All possessed relative quantum yields up to 0.3 absolute 0.93 state, depending on their components. Fluorescence studies showed that the these is highly...
Hypercytokinemia, or cytokine storm, often complicates the treatment of viral and bacterial infections, including COVID-19, leading to risk thrombosis. However, use currently available direct anticoagulants for COVID-19 patients is limited due safety reasons. Therefore, development new remains an urgent task organic medicinal chemistry. At same time, drugs that combine anticoagulant properties with antiviral antidiabetic activity could be helpfull in patients, especially those suffering from...
[1,2,5]Oxadiazolo[3,4-b]pyrazines are of great interest due to their promising photophysical and electrochemical properties, as well potential use in a wide range electronic devices. Herein, we report on the preparation unexpected product derived from interaction 2′-([1,2,5]oxadiazolo[3,4-b]pyrazin-5-yl)-N,N-diphenyl-[1,1′-biphenyl]-4-amine with 2-cyanoacetic acid under basic conditions. The resulting was characterized using 1H 13C NMR spectra, high resolution mass spectrometry,...
