Ключевые слова (''Своб.индексиров.''): nitroaromatic explosives--pyrimidine scaffold
Аннотация: A series of D-​π-​A- type dyes based on pyrimidines, bearing various thiophene linkers, have been studied as sensing fluorophores. Fluorescence studies have demonstrated that the emission of all derivs. is sensitive to the presence of nitroarom. explosives, such as 2,​4,​6-​trinitrophenol (PA)​, 2,​4,​6-​trinitrotoluene (TNT)​, and 2,​4-​dinitrotoluene (DNT)​, in their acetonitrile solns. The detection limits of fluorophores to PA, TNT, and DNT proved to be in the range from 5.83 × 10-​6 to 2.38 × 10-​7 mol​/L, 1.70 × 10-​4 to 8.40 × 10-​6 mol​/L, and 8.39 × 10-​5 to 6.87 × 10-​6 mol​/L, resp. The theor. investigation into the quenching mechanism in the presence of fluorophore has been performed. All compds. have shown a good efficiency as sensor materials when tested as elements of the original device Nitroscan for detecting nitro-​contg. explosives in vapor phase

Аннотация: Various 5-(fluoroaryl)-4-(hetero)aryl substituted pyrimidines have been synthesized based on the Suzuki cross-coupling and nucleophilic aromatic substitution of hydrogen (S-N(H)) reactions starting from commercially available 5-bromopyrimidine and their antitubercular activity against Mycobacterium tuberculosis H(37)Rv has been explored. The outcome of the study disclose that, some of the compounds have showed promising activity in micromolar concentration against Mycobacterium tuberculosis H(37)Rv, Mycobacterium avium, Mycobacterium terrae, and multidrug-resistant strains isolated from tuberculosis patients in Ural region (Russia). The data concerning the 'structure-activity' relationship for fluorinated compounds have been discussed

Аннотация: A novel synthetic route to novel thienoacene systems bearing a fused pyrimidine ring is proposed. The commercially available 5-bromopyrimidine is used as the starting material to obtain various dithienoquinazoline and benzo[f]thieno[3,2-h] quinazoline systems through the Suzuki cross-coupling, nucleophilic aromatic substitution of hydrogen (the S-N(H) reaction), and finally palladium-catalyzed intramolecular cyclization under microwave irradiation. Redox properties of some of the new compounds have been investigated. The data obtained show that these systems have plausible potential for use in organic electronic applications.

Аннотация: The results of the Ural scientific school's organic chemists on the creation of antiviral and antibacterial, including antitubercular, chemopreparations are considered. Basic research data were generalized on the synthesis and study of antiviral activity and the establishment of the metabolism and mechanism of azoloazine series compounds-azaanalogs of adenine and guanine, as well as their nucleosides, which led to the creation of a new family of antiviral substances. One of them, triazavirin, has become a regular therapeutic fixture as an antiflu preparation. The results of synthetic and biological studies on substituted pyrimidines, nucleosides of the benzimidazole and purine series, and other biologically active azaheterocycles are also discussed.

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

Аннотация: Triazolo[5,1-b]purines are rare structural analogues of natural nucleosides and nucleobases purine series. At the same time, prominent representatives of azolopurines exhibit a broad spectrum of antiviral effect, activity against of rheumatoid arthritis, psoriasis, Alzheimer’s, Parkinson’s and etc. Despite the practical value azolo[5,1-b]purines extremely sparingly represented in the chemical literature, due to the complexity of their synthesis. We suggest a convenient way to synthesize triazolopurines with aminotriazolo[1,5-a]pyrimidines (2) as available starting compounds obtained in good yield by reduction of nitro derivatives (1).

Аннотация: Novel donor-pi-acceptor dyes bearing the pyrimidine unit as an electron-withdrawing group have been synthesized by using combination of two processes, based on the microwave-assisted Suzuki cross-coupling reaction and nucleophilic aromatic substitution of hydrogen. Spectral properties of the obtained dyes in six aprotic solvents of various polarities have been studied by ultraviolet-visible and fluorescence spectroscopy. In contrast to the absorption spectra, fluorescence emission spectra displayed a strong dependence from their solvent polarities. The nature of the observed long wavelength maxima has been elucidated by means of quantum chemical calculations. The electrochemical properties of these dyes have been investigated by using cyclic voltammetry, while their photovoltaic performance was evaluated by a device fabrication study. The experimental and calculation data show that all of the dyes can be regarded as potentially good photosensitizers for dye-sensitized solar cells.

The selectivity index of the anti-influenza action of {5-[(4,6-dimethylpyrimidin-2-yl)sulfanyl]-1H-tetrazol1-yl}acetic acid, which has very low cytotoxicity, was twice as high as the selectivity index of the reference drug rimantadine.

Ключевые слова (''Своб.индексиров.''): nitroaromatic explosives--fluorescence quenching--pyridines--pyrazine--pyrimidines--triazines
Аннотация: Highly sensitive and selective detection of nitro containing high energy organic compounds such as picric acid (PA), 2,4,6-trinitrotoluene (TNT) and 2,4-dinitrotoluene (DNT) has become a challenging task due to concerns over national security, criminal investigations and environment protections. Among various known detection methods, fluorescence sensors have gained special attention in recent time. The family of fluorescent sensors based on push-pull systems that incorporate nitrogen heterocycles as an electron-withdrawing group have a growing interest due to their high sensitivity, selectivity and easy tuning. The fluorescent sensors discussed in this review are classified and organized according to used azaheterocyclic scaffold, their functionality and their ability to detect of nitroaromatics by fluorescence quenching.

Аннотация: The reaction tolerance of the multicomponent process between 3-aminoazoles, 1-morpholino-2-nitroalkenes, and aldehydes was studied. The main patterns of this reaction have been established. Conditions for the oxidation of 4,7-dihydro-6-nitroazolo[1,5-a]pyrimidines were selected. Previous claims that the 4,7-dihydro-6-nitroazolo[1,5-a]pyrimidines could not be aromatised have now been refuted. Compounds with an electron-donor substituent at position seven undergo decomposition during oxidation. The phenomenon was explained based on experimental data, electro-chemical experiment, and quantum-chemical calculation. The mechanism of oxidative degradation has been proposed.

Аннотация: Amide unit is a privileged structural motif and is a constituent of proteins, natural products and pharmaceuticals. Amongst different heterocyclic scaffolds, azoles and pyrimidines are the prominent entities in pharmaceutical arena. The biopotency of these heterocycles have triggered to synthesize a variety of heteroaromatics – azoles linked with pyridines by amino acetamide group. The target molecules-azolylaminoacetamidopyrimidines were prepared by the reaction of methyl azolylglycinate with pyrimidinyl-2-amine in the presence of DMAP and triethylamine in dichloromethane under ultrasonication. The lead molecules were evaluated for antimicrobial activity. Nitro substituted 2-((4-(4-chlorofuran-2-yl)thiazole-2-yl)amino)-N-(4,6-diphenylpyrimidin-2-yl)acetamide (9c) displayed excellent antibacterial activity against B. subtilis greater than the standard drug Chloramphenicol. However, 9c and nitro substituted 2-((4-(4-chlorofuran-2-yl)-1H-imidazol-2-yl)amino)-N-(4,6-diphenylpyrimidin-2-yl)acetamide (10c) showed antifungal activity on A. niger greater than the standard drug Ketoconazole.
