Аннотация: This review is focused on consideration of effects of the nature of N,​N'- and N,​O-​bidentate ligands on the structure and optical properties of their B(III) complexes. It has been established that B(III) complexes with asym. N,​N'- and N,​O-​bidentate ligands, such as ortho-​hydroxyphenyl substituted azaheterocycles and heteryl-​β-​ketoimines, exhibit large Stokes shifts, enhanced intensity, and extended range for luminescence in solns. as well as in solid state, comparable with characteristics of the family of BODIPYs derivs. Complexes of some bidentate ligands can be considered as promising fluorophores for applications in biomedical imaging, electroluminescent, solar cell devices, and other fields.

Заглавие : 1H-pyrazole-appended pyridines and their 1,2,4-triazine precursors: a rational synthesis and in silico and in vitro evaluation of anti-cancer activity
Место публикации : European Journal of Organic Chemistry. - 2022. - Vol. 2022, № 22. - С. e202200227
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: An operationally facile and high yielding one-pot protocol has been developed for the preparation of pyridines appended with pyrazole via NH linker. This protocol includes SNipso/aza-Diels-Alder reactions in up to 54 % yields starting from 1,2,4-triazine precursors. All the synthesized compounds have been evaluated for their in silico activity against JAK1, SYK, and FAK1 kinases. The most promising compound was tested in vitro using A-172, Hs578T, and HepG2 cancer cell lines and exhibited considerable cytotoxicity with IC50 values 50 μM in A-172 and HepG2 cell lines. Anticancer in vitro activity correlates well with the predicted in silico data.

Аннотация: The antioxidant and antimutagenic activities of the novel carboxyethyl derivatives of chitosan with three different degrees of substitution have been assayed in vitro in the unicellular flagellate Euglena gracilis subjected to the action of genotoxic agents acridine orange and ofloxacin. It has been demonstrated that chitosan derivatives exhibit concentration-dependent protective antigenotoxic activity against both mutagens. It is suggested that different mechanisms may be involved in its protective action—antioxidant activity in case of ofloxacin-induced DNA damage, as well as possible interaction with the cell membrane that prevents acridine orange from reaching the genetic compartments and subsequent damaging DNA through intercalative binding. Direct adsorption of acridine orange on chitosan derivatives was ruled out as a possible mechanism of protection on the basis of spectrophotometric measurements. Dependence of the antimutagenic properties of the studied chitosan derivatives on the degree of substitution was reversed in experiments involving acridine orange and ofloxacin, which also indicated different mechanisms of protection involved in these two cases.????

Ключевые слова (''Своб.индексиров.''): enteroviruses--enteroviral infection--coxsackievirus
Аннотация: Enteroviruses are non-enveloped viruses of Enterovirus genus, Picornaviridae family, causing a variety of human diseases: from acute respiratory and intestinal infections to more severe pathologies including poliomyelitis, encephalitis, myocarditis, pancreatitis. Currently, no approved direct-acting antiviral drugs for treatment of enterovirus infections exists, whereas vaccination is available only for prevention of poliomyelitis and enterovirus 71 infection. Therefore, it is promising to conduct a search for inhibitors of enteroviruses life cycle in drug development to treat enterovirus infections. Here, antiviral properties of stable free radicals, verdazyls, and their precursors, leucoverdazyls, were investigated. It has been shown that leucoverdazyls vs verdazyls increased the survival of permissive cell culture infected with coxsackievirus. The activity range of the lead leucoverdazyl against RNA-containing and DNA-containing human viruses (in the viral yield reduction assay) and its proposed mechanism of action (time of addition assay) was studied. The lead compound suppressed reproduction of group B enteroviruses in vitro, with modest activity against influenza A virus and no activity against herpes virus type 1 and adenovirus type 5. The maximum decrease in viral titers was observed upon its addition to infected cells during early and middle stages of the virus life cycle. Thus, we concluded that the studied compound has a pronounced inhibitory activity against group B enteroviruses not belonging to the class of capsid binder inhibitors, without virucidal properties. Previously, we described antioxidant properties of leucoverdazyls. It is known that many viral infections are accompanied by production of reactive oxygen species and oxidative stress, and some compounds with antioxidant properties exhibit antiviral potential. Targeted chemical modifications of leucoverdazyls and further studies of leucoverdazyl mechanism of action as well as in vivo animal studies are needed. However, the results obtained may be useful for future development of new antiviral drugs to treat enteroviral infections.

Аннотация: Influenza viruses of types A and B cause periodic pandemics in the human population. The antiviral drugs approved to combat influenza virus infections are currently limited. We have investigated an effective novel inhibitor of human influenza A and B viruses, triazavirine {2-methylthio-6-nitro-1,2,4- triazolo[5,1-c]-1,2,4-triazine-7(4Í)-one} (TZV). TZV suppressed the replication of influenza virus in cell culture and in chicken chorioallantoic membranes, and it protected mice from death caused by type A and B influenza viruses. TZV was also effective against a rimantadine-resistant influenza virus strain and against avian influenza A virus H5N1 strains. The pharmacokinetic parameters and bioavailability of TZV were calculated after the administration of TZV to rabbits. The TZV metabolite AMTZV {2-methylthio-6-amino-1,2,4- triazolo[5,1-s]-1,2,4-triazin(e)-7(4Í)-one} was discovered inÍÅK 293T and Huh7 cell cultures, a liver homogenate, and rabbit blood after intragastric administration of TZV. AMTZV was nontoxic and inactive as an inhibitor of influenza virus in cell culture. Most likely, this metabolite is a product of TZV elimination

Аннотация: The method of thermodynamic simulation was used to study chemical interactions in the cathode half-cell of lithium-ion battery, which contained LiCoO2 as cathode active material and a LiPF6 solution as the electrolyte. It was shown that in the temperature range 298–400 K in thermodynamic equilibrium state a layer of solid products of chemical reaction formed on the cathode/electrolyte interface. The layer predominantly consisted of LiF and LiPO3 in the molar ratio about 2:1 (corresponding to the volume ratio 2:3). In equilibrium state also some soluble interaction products formed, namely: CoF2 (considerable quantity), POF3 and PF5. The concentration of the later two substances was small, but it increased with increase of the temperature. Furthermore, in equilibrium state oxygen gas formed as a product of chemical interactions in cathode half-cell.????Thermodynamic characteristics of Co2O3 and LiCoO2 compounds were determined using a set of calculation methods??

Ключевые слова (''Своб.индексиров.''): drug discovery---nucleosides--herpes simplex virus
Аннотация: A series of 5,6-disubstituted benzimidazole nucleosides, obtained earlier, did not show any significant antiviral activity at relatively low cytotoxicity in vitro. In the course of our research we have succeeded in introducing an additional fluorine atom into the benzimidazole ring system. A new series of 4,6-difluorobenzimidazoles, bearing various groups (fluoro-, methoxy-, ethoxy-, morpholino-, and pyrrolidino-) in the 5-position of the benzene ring, have been synthesized. All these compounds proved to be substrates for recombinant E. coli purine nucleoside phosphorylase (PNP) in the transglycosylation reaction. Effective methods for the synthesis of ribo- and 2′-deoxyribonucleosides with high yields (60–90%) have been described, and the formation of regioisomeric N3-nucleosides of benzimidazoles have been detected. The biological activity of the nucleosides obtained against herpes simplex virus type 1 (HSV-1) has been elucidated. All compounds show a low cytotoxicity in the cell culture Vero E6. 4,5,6-Trifluoro-1-(β-d-ribofuranosyl)benzimidazole and 5-methoxy-4,6-difluoro-1-(β-d-2′-deoxyribofuranosyl)benzimidazole proved to inhibit completely the progression of the virus cytopathic effect (CPE) at a multiplicity of infection (MOI) of 0.01 PFU/cell.

Заглавие : Complexation models of N-(2-carboxyethyl)chitosans with copper(II) ions
Место публикации : Biomacromolecules. - 2005. - Vol. 6, № 1. - С. 189-195. - ISSN 1525-7797. - ISSN 1525-7797

Аннотация: The copper(II) complex formation equilibria of N-(2-carboxyethyl)chitosans with three different degrees of substitution (DS = 0.42, 0.92, and 1.61) were studied in aqueous solution by pH-potentiometric and UV-spectrophotometric techniques. It was demonstrated that the complexation model of CE-chitosans depends on DS: the [Cu(Glc-NR2)2] complexes are predominant for two lower substituted samples ("bridge model", log ?12 = 10.06 and 11.6, respectively), whereas the increase of DS leads to formation mainly of the [Cu(Glc-NR2)] complexes ("pendant model", log ?11 = 6.41). As a model for copper complexation with a disubstituted residue of CE-chitosan, the complex of N-methyliminodipropionate [CuMidp(H2O)]·(H2O) was synthesized and structurally characterized by XRD. The unit cell consists of two crystallographically nonequivalent Cu atoms having slightly distorted square pyramidal coordination; Midp constitutes the basal plane of the pyramid and acts as a tetradentate NO3 chelate-bridging ligand by the formation of two six-membered chelate rings (average Cu-O 1.99 A, Cu-N 2.04 A) and a bridge via carbonyl O atom (average Cu-O 1.99 A), an apical position is occupied by a water molecule (average Cu-Ow 2.30 A).

Аннотация: These data are related to our previous paper “Synthesis and approbation of new neuroprotective chemicals of pyrrolyl-and indolylazine classes in a cell model of Alzheimer’s disease” (Dutysheva et al., 2021), in which we demonstrate neu-roprotective abilities of pyrrolyl- and indolylazines in a cell model of Alzheimer’s disease. Using a novel procedure of photocatalysis we have synthesized a group of new compounds. The current article presents nuclear magnetic resonance spectra including heteronuclear single quantum coherence spectra of chemicals synthesized by us. The effect of new compounds have on heat shock proteins genes expression in reprogrammed human neurons are presented. We also presented data that verify neuronal phenotype of reprogrammed cells.

Аннотация: Diesters on the basis of 16-hydroxyisosteviol and dicarboxylic acids, exhibiting anti-tubercular activity, transport Fe(III) through liquid chloroform membrane which models a cell membrane. It is revealed that fluxes and anti-tubercular activity increase, as the length of the chain (spacer) between two ent-beyran skeletons of diesters increases. Computations on the level DFT/PBE explain the dependence of complexes stability on a structure of diterpenoid ligands. The structures of three diesters were established by single crystal X-ray analysis. ??

Ключевые слова (''Своб.индексиров.''): гипотермия--hypothermia--1,3,4-thiadiazine--метаболиты мозга--brain metabolites--терморегуляция--thermoregulation
Аннотация: The aim of the present study was to examine how administration of a compound of 1,3,4-thiadiazine class 2-morpholino-5-phenyl-6H-1,3,4-thiadiazine, hydrobromide (L-17) with hypothermia inducing properties affects the brain metabolism. The mechanism by which L-17 induces hypothermia is unknown; it may involve hypothalamic central thermoregulation as well as act via inhibition of energy metabolism. We tested the hypothesis that L-17 may induce hypothermia by directly inhibiting energy metabolism. The study in vivo was carried out on Sprague-Dawley adult rats. Two doses of L-17 were administered (190 mg/ kg and 760 mg/kg). Brain metabolites were analyzed in control and treated groups using magnetic resonance spectroscopy, along with blood flow rate measurements in carotid arteries and body temperature measurements. Further in vitro studies on primary cultures from rat hippocampus were carried out to perform a mitochondria function test of L-17 preincubation (100 μM, 30 min). Analysis of brain metabolites showed no significant changes in 190 mg/kg treated group along with a significant reduction in body temperature by 1.5ÊC. However, administration of L-17 in higher dose 760 mg/kg provoked changes in brain metabolites indicative of neurotoxicity as well as reduction in carotid arteries flow rate. In addition, a balance change of excitatory and inhibitory neurotransmitters was observed. The L-17 pre-incubation with cell primary cultures from rat brain showed no significant changes in mitochondrial function. The results obtained in the study indicate that acute administration of L-17 190 mg/kg in rats induces mild hypothermia with no adverse effects onto brain metabolism.

Ключевые слова (''Своб.индексиров.''): antiviral drug--nucleotide analogue--remdesivir
Аннотация: Nucleotide analogues are the divergent scaffolds that are reliable potential therapeutic drugs to treat the wide range of diseases including viral infections. For instance, Remdesivir is a biologically important nucleotide analogue prodrug that can act as a key drug target for the diseases Ebola and COVID-19. Remdesivir is a structurally chiral aryloxy-phosphoramidate prodrug as it is metabolized into nucleoside triphosphate (active drug form) inside the cell through sequential reactions by ester mediated-hydrolysis. Thus, the current minireview focuses on the earlier reported synthetic approaches of key fragments of remdesivir and their developments to attain the scale-up yields of the drug for clinical/commercial applies. Further, this review serves as a template for the design and development of other complex organic molecules.

Место публикации : Russian chemical bulletin. - 2021. - Vol. 70, № 6. - С. 1199-1208
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Peculiar features of the modification of Fe3O4 magnetic nanoparticles (MNPs) obtained by co-precipitation from solutions of FeII and FeIII salts (10-nm MNPs) and by the gas-condensation method (30-nm MNPs) with 3-aminopropylsilane and then with L-lysine were studied. The chemically obtained MNPs possess more pronounced hydrophilic properties and therefore readily form stable aqueous colloidal solutions and can be loaded with a larger amount of L-Lys. However, samples based on the physically obtained MNPs were characterized by more efficient internalization and longer retention times by the NIH 3T3 cells. The results obtained can be used in the design of novel nanomaterials for magnetic cell labeling.

Аннотация: New 2-aryl-1,2,3-triazolopyrimidines were designed, synthesized, and characterized. Their optical properties were thoroughly studied in the solid phase, in solution and in a biological environment. Density Functional Theory (DFT) based calculations were performed, including the molecular geometry optimization for both the ground state and the first singlet excited state, the prediction of the UV-Vis absorption and fluorescence spectra, the determination of the molecular electrostatic properties and the solvent effect on the optical properties. The emission intensity was revealed to increase in time upon irradiation. Mass spectrometric research, quantum mechanical calculations, and analysis of literature data suggested a possible photo-transformation pathway through the homolytic cleavage of one of the C–Cl bonds upon irradiation with UV light. The structure of the active intermediate was identified by the series of mass spectrometry experiments and via synthesis of putative transformation products. The kinetic parameters measured in different solvents allowed estimating the rate of these photo-transformations. Biological experiments demonstrated that 2-aryl-1,2,3-triazolopyrimidines penetrate cells and selectively accumulate in the cell membrane and the Golgi complex and endoplasmic reticulum. Their unique properties pave the way for new possible applications of fluorescent 8-azapurines in biology and medicine.

Заглавие : Pyrrolylquinoxaline-2-one derivative as a potent therapeutic factor for brain trauma rehabilitation
Место публикации : Pharmaceutics. - 2020. - Vol. 12, № 5. - С. 414
Ключевые слова (''Своб.индексиров.''): apoptosis--cerebrospinal fluid--hsp70--small molecule--traumatic brain injury
Аннотация: Traumatic brain injury (TBI) often causes massive brain cell death accompanied by the accumulation of toxic factors in interstitial and cerebrospinal fluids. The persistence of the damaged brain area is not transient and may occur within days and weeks. Chaperone Hsp70 is known for its cytoprotective and antiapoptotic activity, and thus, a therapeutic approach based on chemically induced Hsp70 expression may become a promising approach to lower post-traumatic complications. To simulate the processes of secondary damage, we used an animal model of TBI and a cell model based on the cultivation of target cells in the presence of cerebrospinal fluid (CSF) from injured rats. Here we present a novel low molecular weight substance, PQ-29, which induces the synthesis of Hsp70 and empowers the resistance of rat C6 glioma cells to the cytotoxic effect of rat cerebrospinal fluid taken from rats subjected to TBI. In an animal model of TBI, PQ-29 elevated the Hsp70 level in brain cells and significantly slowed the process of the apoptosis in acceptor cells in response to cerebrospinal fluid action. The compound was also shown to rescue the motor function of traumatized rats, thus proving its potential application in rehabilitation therapy after TBI.

Заглавие : Stimuli-responsive dual cross-linked N-carboxyethylchitosan hydrogels with tunable dissolution rate
Место публикации : Gels. - 2021. - Vol. 7, № 4. - Ст.188
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Ключевые слова (''Своб.индексиров.''): hydrogels--chitosan--salicylaldehyde
Аннотация: Here, we discuss the applicability of (methylenebis(salicylaldehyde)—MbSA) for the fabrication of the stimuli-responsive N-carboxyethylchitosan (CEC) hydrogels with a tunable dissolution rate under physiological conditions. In comparison with non-covalent salicylimine hydrogels, MbSA cross-linking via covalent bis(‘imine clip’) and non-covalent hydrophobic interactions allowed the fabrication of hydrogels with storage moduli 1 kPa at ten-fold lower aldehyde/CEC molar ratio with the preservation of pH- and amino-acid responsive behavior. Although MbSA-cross-linked CEC hydrogels were stable at neutral and weakly alkaline pH, their disassembly in cell growth medium (Dulbecco’s modified Eagle’s medium, DMEM) under physiological conditions was feasible due to transimination reaction with amino acids contained in DMEM. Depending on the cross-linking density, the complete dissolution time of the fabricated hydrogels varied from 28 h to 11 days. The cytotoxicity of MbSA cross-linked CEC hydrogels toward a human colon carcinoma cell line (HCT 116) and primary human dermal fibroblasts (HDF) was remarkably lower in comparison with CEC-salicylimine hydrogels. Fast gelation, relatively low cytotoxicity, and tunable stimuli-induced disassembly under physiological conditions make MbSA cross-linked CEC hydrogels promising for drug encapsulation and release, 3D printing, cell culturing, and other biomedical applications.

Аннотация: Tri- and pentacyclic fluoroquinolones were synthesized by intramolecular cyclization of the corresponding 3-hydrazinopolyfluorobenzoylacrylates followed by substitution of fluorine atoms by amine residues. The antitumor activity of the resulting compounds was studied at the National Cancer Institute using cultures of 60 cell lines of nine groups, including leukemia, lung tumor, large intestine tumor, CNS tumor, melanoma, ovary tumor, renal tumor, prostate tumor, and breast tumor. Relationships between structure and antitumor activity were analyzed. In vivo experimental data from hollow fiber tests are presented for two derivatives
