Аннотация: The acidity and basicity constants of isomeric phenyl(aryl)-1,2,4-triazin- 3- and -5-ones in aqueous solution were determined by spectrophotometry: pK a = 7.3-6.2; pKBH+ = 0.1 to -2.2. 1,2,4-Triazin-3-ones are weaker bases than the corresponding 1,2,4-triazin-5-ones. According to the AM1 calculations, the most thermodynamically favorable tautomer in the gas phase is the oxo form: namely, 2H-tautomers of the neutral bases and 2,4-H,H +-tautomers of the conjugate acids.

Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Di(het)areno[e,l][1,3]diazapyrene core was constructed by FeCl3-mediated intramolecular oxidative cyclodehydrogenation of 5-[2,6-di(het)arylphenyl]pyrimidine precursors, which in turn were obtained by the Suzuki cross-coupling of 5-(2,6-dibromophenyl)pyrimidine derivative with the corresponding (het)arylboronic acids. Molecular orbital calculations as well as redox and photophysical measurements show that the fused products are promising for organic electronic application.

CHITOSAN -- CHEMICAL MODIFICATION -- GEL TECHNIQUE
Аннотация: This study presents a new approach for direct carboxyalkylation of chitosan in the gel state by using aza-Michael addition and substitution reactions. Various reagents were applied including acrylic and crotonic acids, and alpha-, beta-, gamma-, delta-, and epsilon-halocarboxylic acids. The reaction of chitosan with gamma- and delta-halocarboxylic acids showed no target product formation either in solution or in the gel state. In the case of acrylic, crotonic, alpha- and beta-halocarboxylic acids, the reaction performed in the gel state (concentration of chitosan 20-40%) shows higher degree of substitution at lower reaction time and temperature than in diluted solutions (concentration of chitosan 0.5-2%). The results were discussed in terms of kinetics of the target and side reactions. H-1 and C-13 NMR confirmed that in all cases the carboxyalkylation of chitosan proceeds exclusively at the amino groups

BETA-LACTAM ANTIBIOTICS -- BORON NEUTRON CAPTURE THERAPY -- FLUOROQUINOLONES -- HETEROCYCLES
Аннотация: A brief review of chemical elements, compounds from which find application in medicine, ranging from the commonly occurring organogenic elements (carbon, hydrogen, nitrogen, oxygen, sulfur, and phosphorus), composing the structure of proteins and nucleic acids of the cells of living organisms and determining the genetic transmission, to native rarely encountered organic fluorine compounds, synthetic derivatives of which have become firmly ingrained in the arsenal of modern pharmaceutical drugs, is given. Strong emphasis is put on metalloproteins, which play a significant role in the biochemistry of vitally essential processes, as well as metal compounds that are widely used in medicine. Of particular importance are the chemical elements and the isotopes, compounds of which are employed in nuclear medicine for diagnostics and treatment of a wide range of diseases, oncological and cardiovascular in particular.

Synthetic approaches to the quinolone system, as well as all kind of structural modifications by incorporating substituents into 1–8 positions or by means of annelation have been discussed. The “structure-activity” relationships for antibacterial fluoroquinolones, as well as the data on other types of biological activity for the family of bi- and polycyclic fluoroquinolones are presented. The formation of complexes of fluoroquinolones with metals and their applications have been considered. The bibliography

Аннотация: Crown ethers form strong proton-acceptor complexes with CF3COOH or C4F9COOH that undergo thermal decarboxylation at 200–260 °C which results in 60–80% of CF3H or C4F9H (including up to 20 % of a mixture of C4F8). Critical parameters of the process were determined in relation to the temperature and amount of crown ether. The relative activities of different crown ethers in decarboxylation were also established. A scheme is proposed that explains the effect of the structure of crown ethers on this reaction. The data obtained substantiate the view that the topological correspondence concept is insufficient to explain the ability of crown ethers to form complexes with cat
