Аннотация: The reactions of alkyl tri-and tetrafluorosalicylates with diethylamine led to formation of the stable salts regardless of the conditions. Therein, ethyl esters were undergone dealkylation leading to formation of diethylammonium carboxylates. Methyl tetrafluorosalicylate was subject to similar transformations, while trifluoro-containing analog gave salt at the hydroxyl group and in which ester fragment was remained.

Заглавие : Stereoselective synthesis of dihydropyrimidinethione podand in the presence of L-proline or 4-hydroxy-L-proline and metal nitrates
Место публикации : Russian chemical bulletin. - 2022. - Vol. 71, № 7. - С. 1506-1513
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: The asymmetric Biginelli reaction involving a 3-oxobutanoyl-containing podand, benzaldehyde, and thiourea was studied using secondary amines as a chiral inductor, Brönsted acid as a catalyst, and metal salts (especially metal nitrates) as an additive of asymmetric catalysis (AAC) was studied. The tuberculostatically active dihydropyrimidine-thione-containing podand was synthesized with an enantiomeric excess of 57% in the presence of 4-hydroxy-L-proline. In the presence of metal nitrates, the influence of the ionic radius of the cation on the enantioselective excess of the reaction under study was observed, which made it possible to propose a possible mechanism of chiral induction controlled by the complexing ability of the initial β-ketoester-containing podand with metal ions and coordination of the reagents in the transition states.

Заглавие : The ability of new diaminoalkanes and their additive salts, effective in the mouse survival test, to protect the blood system in the bone marrow form of acute radiation disease

Аннотация: A complex of parameters of the blood system of BALB/c mice was studied using alkanes symmetrically and asymmetrically replaced with heterocyclic amines, which protected 85–100% of mice after total exposure to 137Cs γ-radiation at the minimum lethal dose. The ability of substances of different structures to protect hematopoietic tissue in in vivo and in vitro experiments has been established. Differences in the rates of post-radiation repopulation of blood cells in protected mice were revealed, which are associated with the survival of the organism. It was found that the response to the effect of the investigated substances at the level of the organism (acute toxicity, anti-radiation activity, oxygen consumption by the body) and hematopoietic tissue (changes in cellularity in the hematopoietic organs and peripheral blood) depends on the structure of the substance (length of the aliphatic chain, acidic component).

Ключевые слова (''Своб.индексиров.''): nitro-1,2,4-triazolo[1,5a]pyrimidines--triazid--nitro group transformations--nitroaromatic compounds
Аннотация: This article presents the results of a study of electrochemical transformations in aqueous and aprotic media of 5-methyl-6-nitro-7-oxo-4,7-dihydro-1,2,4-triazolo[1,5-a]pyrimidinide l-arginine monohydrate (1a, Triazid) obtained by electrochemical methods and ESR spectroscopy. The effect of pH on the current and the reduction potential of 1a in an aqueous Britton–Robinson buffer solution was studied. It was found that 1a is irreversibly reduced in aqueous acidic media on a glassy carbon electrode in one stage with the participation of six electrons and the formation of 5-methyl-6-amino-7-oxo-1,2,4-triazolo[1,5-a]pyrimidin. The electroreduction of 1a in DMF on a background of tetrabutylammonium salts proceeds in two stages, controlled by the kinetics of second-order reactions. In the first stage, the reduction of 1a is accompanied by protonation by the initial compound of the basic intermediate products formed in the electrode reaction (self-protonation mechanism). The second quasi-reversible stage of the electroreduction 1a corresponds to the formation of a dianion radical upon the reduction of the heterocyclic anion 5-methyl-6-nitro-7-oxo-4,7-dihydro-1,2,4-triazolo[1,5-a]pyrimidin, which is formed upon the potentials of the first peak. The ESR spectrum of the radical dianion was recorded upon electroreduction of Triazid in the presence of Bu4NOH. The effect of the formation of ion pairs on the reversibility of the second peak of the 1a transformation is shown. A change in the rate and regioselectivity of the protonation of the dianion radical in the presence of Na+ and Li+ ions is assumed. The results of studying the electroreduction of 1a by ESR spectroscopy with a TEMPO trap make it possible to assume the simultaneous formation of both a nitroxyl radical and a radical with the spin density localized on the nitrogen at the 4 position of the six-membered ring

Заглавие : Modification of chemically and physically obtained Fe3O4 magnetic nanoparticles with L-Lys for cell labeling
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.

Заглавие : Functionalized trifluoromethyl-containing lithium β-diketonate in the synthesis of homo- and heteronuclear complexes of rare-earth metals
Место публикации : Russian Journal of Coordination Chemistry. - 2021. - Vol. 47, № 4. - С. 280-295
Ключевые слова (''Своб.индексиров.''): β-diketonates--lanthanides--19f nmr spectroscopy--mass spectrometry
Аннотация: The reactions of functionalized lithium CF3-β-diketonate (LiL) with trivalent rare-earth metal salts in methanol afford homobinuclear and heterobi(tri)nuclear complexes depending on the nature of the transition metal and anion (chlorides, nitrates, and acetates). In the cases of lanthanum(III) and cerium(III), homoleptic complexes [(LnL3)2] are isolated (CIF files CCDC nos. 2031097 (Ia) and 2031102 (Ib)). The reaction of LiL with praseodymium(III) nitrate gives the new trimetallic structure [(LiPrL3)(LiL)(NO3)(H2O)2] (CIF file CCDC no. 2031103 (II)), and the replacement of nitrate by chloride gives [(PrL3)(LiL)(H2O)] (CIF file CCDC no. 2031104 (IIIa)). Regardless of the nature of the anion of the salt in the series from neodymium(III) to ytterbium(III) and yttrium(III), Ln–Li β-diketonates [(LnL3)(LiL)(solv)] (solv is H2O and MeOH) are formed, and their structures are characterized by X-ray structure analysis (CIF files CCDC nos. 2031099 (IIIb), 2031100 (IIIc), 2031098 (IVa), 2031096 (IVc), 2031094 (IVf), 2031101 (IVg), and 2031095 (IVh)). The equilibrium of the diketonate isomeric forms in a solution of deuterated dimethyl sulfoxide is studied by 19F NMR spectroscopy, and the qualitative composition of the polynuclear complexes is determined by mass spectrometry.

Аннотация: Data on anodic dehydroaromatization of 9,10-dihydroacridines, bearing aryl and heteroaryl fragments, are presented. Effects of both electron-donating and electron-withdrawing substituents on the current-voltage characteristics of these compounds have been established. The experimental data proved to be in a good agreement with quantum chemical calculations. A simple and convenient method for the electrochemical conversion of dihydroacridines into the corresponding 9-(hetero)aryl-N-methylacridinium salts has been advanced

Ключевые слова (''Своб.индексиров.''): pyrazines--antituberculosis activity--2(1h)-pyrazinone
Аннотация: A simple method based on hydrolysis of 2,3-dicyanopyrazinium salts has been used for the synthesis of the corresponding 5-(hetero)aryl-3-cyano-1-ethyl-2(1H)-pyrazinones. Also, the series of novel 1-ethyl-5-(hetero)aryl-1,6-dihydropyrazine-2,3-dicarbonitriles have been obtained through reduction of the same pyrazinium salts with triethylsilane. The obtained compounds proved to be active in micromolar concentrations in vitro against Mycobacterium tuberculosis H37Rv, Mycobacterium avium, Mycobacterium terrae, as well as against rifampicin and isoniazid-resistance strains of Mycobacterium tuberculosis. The data for acute in vivo toxicity in mice have been obtained for these compounds which appear to be promising antitubercular agents

Аннотация: The behavior of 4-thienyl substituted pyrimidine ligands (L1-3) has been studied for the series of their reactions with various salts of 3d metals (Co, Zn, Ni, Cu) and platinoids (Pt, Pd). In particular, mononuclear Co(OTf)(2)(L1-3)(2)(H2O)(2)(MeCN)(2) (1), binuclear Co-2(Piv)(2)(L1-3)(4) (2a,b), Cu-2(Piv)(2)(L1-3)(2) (5a,b), heterometallic polynuclear Li2Co2(Piv)(6)(L1-3)(2) (4) and chelate [(L-1)Pd(OAc)](2) (6) complexes have been obtained. The structures of all complexes have been established by X-ray diffraction. Also magnetic properties of coordination compounds 1, 2, 4 and 5 have been studied in details. In particular, mononuclear Co(II) complexes I and 4 proved to exhibit paramagnetism with large positive zero-field splitting parameters. Dinuclear Co(II) complexes 2a,b show weak antiferromagnetic interactions. Dinuclear Cu(II) complexes 5a,b demonstrate strong antiferromagnetic superexchange interactions via four carboxylate bridges. The systems 2a,b and 5a,b are isolated as exchange coupled dimers
