Reactions of p-Nitrophenyloxirane with Amines Containing Fragments with Bicyclic Skeleton
(Pleiades Publishing, 2002) Kas'yan, A. O.; Golodaeva, E. A.; Tsygankov, A. V.; Kas'yan, L. I.
Reactions of p-nitrophenyloxirane with amines containing fragments with bicyclic skeleton of norbornene, norbornane, epoxynorbornane (stereoisomeric exo- and endo-5-aminomethylbicyclo[2.2.1]hept-2-enes, N-benzyl-endo-5-aminomethylbicyclo[2.2.1]hept-2-ene, endo-5-(2-aminoethyl)bicyclo[2.2.1]hept-2-ene, stereoisomeric exo- and endo-2-aminomethylbicyclo[2.2.1]heptanes, 2-(1-aminoethyl)bicyclo[2.2.1]-heptane, exo-5-aminomethyl-exo-2,3-epoxybicyclo[2.2.1]heptane) were investigated. The aminolysis of pnitrophenyloxirane occurred regioselectively according to Krasusky rule as was proved by 1H and 13C NMR data. As shown by 1H and 13C NMR spectroscopy the oxyalkylation product obtained from N-benzyl-endo-5-aminomethylbicyclo[2.2.1]hept-2-ene was composed of two diastereomers originating from the presence of a chiral nitrogen atom in the rear part of the rigid bicyclic skeleton. New products of amino groups transformation in the molecules of hydroxyamines were obtained by reaction with p-methylbenzoyl chloride and p-nitrophenylsulfonyl chloride. Regioselectivity of the attack of electrophilic reagents on the nitrogen in the hydroxyamines was confirmed by IR and 1H NMR spectra of the products. The data on pharmacological activity tests of N-2-hydroxyethyl(p-nitrophenyl)-5-aminomethylbicyclo[2.2.1]hept-2-ene are reported.
A study of cell membranes in nasal epithelial cells from patients with chronic rhinosinusitis with nasal polyps by means of a fluorescent probe
(2019) Onishchenko, A. I.; Tkachenko, A. S.; Nakonechna, O. A.; Korniyenko, Y. M.; Ryshchenko, I. M.; Tsygankov, A. V.; Posokhov, Ye. O.
Aim. To assess the state of membranes in nasal epithelial cells obtained from the patients with chronic rhinosinusitis with nasal polyps (CRSwNP) with the help of the fluorescent probe 2-(2ʹ-ОН-phenyl)-5-phenyl-1,3-oxazole. Methods. The state of membrane phospholipid bilayer in suspensions of nasal epithelial cells isolated from ten patients with CRSwNP was evaluated using the fluorescent probe 2-(2ʹ-ОН-phenyl)-5-phenyl-1,3-oxazole that reacts on the physico-chemical properties of its microenvironment. Changes in fluorescence spectra were determined using a Thermo Scientific Lumina fluorescence spectrometer (Thermo Fisher Scientific) 1 hour after the addition of the probe to nasal epithelial cell suspensions. Results. CRSwNP was found to be associated with a higher rate of nasal epithelial cell membrane hydration in the region of phospholipid glycerol moiety, carbonyl groups and aliphatic chains of fatty acids attached to the carbonyl groups. Conclusion. Our findings suggest that CRSwNP is accompanied by the elevated hydration rate of the most polar region, namely polar heads of phospholipids of nasal epithelial cell membranes.

(Elsevier Inc., 2012) Shtamburg, V. G.; Tsygankov, A. V.; Shishkin, O. V.; Zubatyuk, R. I.; Shtamburg, V. V.; Gerasimenko, M. V.; Mazepa, A. V.; Kostyanovsky, R. G.
A study of enterocyte membranes during activation of apoptotic processes in chronic carrageenan-induced gastroenterocolitis
(Medical Association of Zenica-Doboj Canton, 2018) Tkachenko, A. S.; Marakushyn, Dmytro; Kalashnyk, Iuliia; Korniyenko, Yevgen; Onishchenko, Anatolii; Gorbach, Tatyana; Nakonechna, Oksana; Posokhov, Ye. O.; Tsygankov, A. V.
Aim. To investigate the lipid membranes of rat enterocytes in chronic carrageenan-induced gastroenterocolitis accompanied by the activation of apoptotic processes. Methods. Steady-state fluorescence spectroscopy: a study by fluorescent probes – by ortho-hydroxy derivatives of 2,5-diaryl-1,3-oxazole. Activity of apoptosis signal-regulating kinase 1 and poly (ADP-ribose) polymerase in small intestinal homogenates, blood serum levels of matrix metalloproteinase-2 and caspase-3 and the level of DNA fragmentation in small intestinal homogenates were determined. Results. Biochemical analysis revealed that an activation of apoptotic processes occurred in the intestinal epithelium of rats during chronic carrageenan-induced gastroenterocolitis. The fluorescence probes showed that activation of apoptotic processes in carrageenan-induced gastroenterocolitis was accompanied by changes in polar regions of rat enterocyte membranes, while no changes were revealed in more hydrophobic regions of the membranes. Conclusion. The increase in hydration of membranes was attributed to the activation of the apoptosis of enterocytes. It has been shown that a fluorescent probe (2-(2′-hydroxyphenyl)-5-phenyl-1,3-oxazole) can be used for the detection of apoptosis of enterocytes.
Doebner-type pyrazolopyridine carboxylic acids in an Ugi four-component reaction
(BioMed Central, United Kingdom, 2019) Murlykina, M. M.; Kolomiets, O. V.; Kornet, M. M.; Sakhno, Y. I.; Desenko, S. M.; Dyakonenko, V. V.; Shishkina, S. V.; Brazhko, O. A.; Musatov, V. I.; Tsygankov, A. V.; Van der Eycken, E. V.; Chebanov, V. A.
Substituted 1H-pyrazolo[3,4-b]pyridine-4- and 1H-pyrazolo[3,4-b]pyridine-6-carboxamides have been synthetized through a Doebner–Ugi multicomponent reaction sequence in a convergent and versatile manner using diversity generation strategies: combination of two multicomponent reactions and conditions-based divergence strategy. The target products contain as pharmacophores pyrazolopyridine and peptidomimetic moieties with four points of diversity introduced from readily available starting materials including scaffold diversity. A small focused compound library of 23 Ugi products was created and screened for antibacterial activity.

Synthesis and structure of N-alkoxyhydrazines and N-alkoxy-N',N',N'-trialkylhydrazinium salts
(Elsevier Inc., 2013) Shtamburg, V. G.; Shishkin, O. V.; Zubatyuk, R. I.; Shtamburg, V. V.; Tsygankov, A. V.; Mazepa, A. V.; Kadorkina, G. K.; Kostyanovsky, R. G.
New types of 1,1,1-trialkyl-2-alkoxyhydrazinium chlorides and N-alkoxyhydrazines were obtained by reactions of N-chloro-N-alkoxyureas with trimethylamine or 1,4-diaza[2.2.2]bicyclooctane and by reactions of methyl N chloro-N-methoxycarbamate with potassium salt of N-acetylbenzenesulfonylamide. The XRD studies of N,N' bis(methoxycarbonyl)-N,N'-dimethoxyhydrazine, N'-methoxy-N'‑methoxycarbonyl-N-acetylbenzenesulfonylhydrazide and 1,1,1-trimethyl-2-methoxyhydrazinium perchlorate revealed the pyramidal configuration of the central nitrogen atoms in O–N–N geminal system, unusual elongation of N–N+ bond and shortening of N–OMe bond in 1,1,1-trimethyl-2-methoxyhydrazinium perchlorate.
The properties and structure of N-chloro-N-methoxy-4-nitrobenzamide
(Elsevier Inc., 2012) Shtamburg, V. G.; Tsygankov, A. V.; Shishkin, O. V.; Zubatyuk, R. I.; Uspensky, B. V.; Shtamburg, V. V.; Mazepa, A. V.; Kostyanovsky, R. G.
The XRD study of N-chloro-N-methoxy-4-nitrobenzamide revealed the high pyramidality degree of its amide nitrogen atom in O–N–Cl moiety. N-Chloro-N-methoxy-4-nitrobenzamide reacts with AcONa in MeCN selectively forming N-acetoxy-N-methoxy-4-nitrobenzamide, whereas its methanolysis in the presence of AcONa yields N,N' bis(4-nitrobenzoyl)-N,N'-dimethoxyhydrazine.
