The results of experimental studies of the interaction of the S-protein with a monohetaryl-substituted porphyrin containing a benzimidazole residue are presented. It has been revealed that the S-protein forms high-affinity complexes with the specified porphyrin. The porphyrin binding by the SARS-CoV-2 S-protein has proceeded stepwise; at the first ...

Computational study of some details of the cyclization reaction between 3,5-diacetyl-2,6-dimethylpyridine and salicylic aldehyde in an acidic medium was performed by the DFT RB3LYP/6-31G method using the Gaussian-2016 software package. It was shown that protonation of the pyridine nitrogen atom leads to a significant increase in the charge of the h...

Sequential reaction of 2-chlorobenzaldehyde, cyanothioacetamide, and malononitrile dimer in the presence of an excess of N -methylmorpholine resulted in the formation of N -methylmorphlinium salt of 2-amino-4-(2-chlorophenyl)-6-(dicyanomethyl)-1,4-dihydropyridine-3,5-dicarbonitrile. The resulting salt reacts under Mannich conditions with primary am...

AbstractThe spectral characteristics of dithiomalondianilide (N,N′-diphenyldithiomalonodiamide) were studied, and the dissociation constant was determined by potentiometric titration. Quantum-chemical methods at the B3LYP-D3BJ/6-311+G (2d,p) level were used to calculate the molecular geometry and vibrational spectra of the most stable tautomeric fo...

AbstractA series of 1,3,4-oxadiazole bridged pyrazole/isoxazole bearing quinoline derivatives has been designed and synthesized by a clean and convenient method. Structures of the newly synthesized compounds have been confirmed by FTIR, 1H and 13C NMR, and HRMS spectral data. The titled compounds have been evaluated for their molecular docking guid...

AbstractThe article summarizes the results of studies of coexisting forms of metals (Al, Fe, Mn, Cu, Cr, Zn, and Pb) in some lakes of the Kiev city for the period of 2007–2019. The data on seasonal distribution of the metals into the suspended and dissolved forms are presented. It is shown that some of them migrate mainly in the dissolved state, wh...

AbstractThe composition and quality of water in the Malka River at the present time were determined as a result of the monitoring of the concentrations of trace elements and nutrients in the foothills and estuaries over a period of 2002‒2019. Comparison of the resulting data showed that in recent years the concentration of some elements has increas...

AbstractThe suitability of a combined tanning system comprising zinc salts and an organic tanning agent as an alternative to chromium compounds was considered. The structure of the organic tanning agent synthesized on the basis of formaldehyde and ethanolamine was identified by IR spectroscopy. The effect of the zinc salts on the viscosity and pH o...

AbstractThe results of long-term monitoring the total mercury and methylmercury levels in the bottom sediments of Lake Baikal are reported for the first time. It was shown that the levels of mercury and methylmercury in the lake sediments are within the range of the levels characteristic of unpolluted freshwater bodies. The factors affecting the ac...
