    Thiocarbamoyl chitosan: Synthesis, characterization and sorption of Au(III), Pt(IV), and Pd(II) [Text] / S. YU. Bratskaya, A. Yu. Ustinov, Yu. A. Azarova, A. V. Pestov // Carbohydrate Polymers. - 2011. - Vol. 85, № 4. - P854-861 : ил. - Bibliogr. : p. 860-861 (39 ref.)

Аннотация: Here we suggest a new method of chitosan sulfur derivatives (thiocarbamoylchitosans, TC-chitosans) synthesis via reaction in eutectic two-component system ammonium rodanide–thiourea that allows significant increase of substitution degrees at the reduced time and reagent consumption as compared to conventional synthetic procedures. The sorption properties of TC-chitosans with substitution degrees (DS) from 0.4 to 0.9 toward Au(III), Pt(IV), Pd(II) ions were studied in chloride solutions, including systems with 10 to 1000-fold excess of Fe(III), Cu(II), and Zn(II) over the precious metal ions content. The sorption capacities of TC-chitosans increase with DS and change in the row: Au(III) Pd(II) Pt(IV) ? Cu(II) Fe(III) Zn(II). The maximum sorption capacities of TC-chitosan with DS 0.9 for Pt(IV), Pd(II), and Au(III) were 1.24 mmol/g, 3.43 mmol/g, and 3.81 mmol/g, respectively. Characterization of precious metals oxidation states by the XPS method after the sorption on TC-chitosan revealed that the platinum and gold recovery occurred with reduction of Au(III) to Au(I)/Au(0) and Pt(IV) to Pt(II)????

    Synthesis, analgesic and antipyretic activity of 2-(antipyrin-4-yl)hydrazones of 1,2,3-triketones and their derivatives [Electronic resource] / E. V. Shchegol'kov, O. G. Khudina, L. V. Anikina, Ya. V. Burgart, V. I. Saloutin // Pharmaceutical Chemistry Journal. - 2006. - Vol. 40, № 7. - P373-376. - Библиогр. : с. 376 (10 назв.)

Аннотация: 1,2,3-Triketone 2-(antipyrin-4-yl)hydrazones were synthesized via the azo-coupling reactions of 1,3-diketones with 2-(antipyrin-4-yl)diazonium chloride. The fluoroalkyl-containing hetarylhydrazone enters into cyclocondensation with hydrazines at the 1,3-dicarbonyl fragment to yield 3-tetrafluoroethyl derivatives of pyrazole. It was found that 1,2,3-triketone 2-(antipyrin-4-yl)hydrazones and N-(2-hydroxyethyl)-substituted pyrazole exhibit analgesic activity comparable with that of their structural analog analgin (metamizole sodium), but do not possess antipyretic properties. In contrast, N-phenyl-substituted pyrazole did not exhibit analgesic properties but produced a certain antipyretic effect four hours after pyrogenic administration. Fluoroalkyl-containing compounds are less toxic substances than nonfluorinated 2-(antipyrin-4-yl)hydrazone and analgin.

SYNTHESIS -- PYRAZOLES -- TUBERCULOSTATIC ACTIVITY
Аннотация: Alkylation of polyfluoroalkyl-containing pyrazoles with 4-bromobutyl acetate in acetone in the presence of potassium carbonate leads to a mixture of isomeric 1-(4-acetoxybutyl)-3-fluoroalkyl- and 1-(4-acetoxybutyl)-5-fluoroalkylpyrazoles, which in a number of cases were successfully separated by HPLC. Deacylation in acidic medium with gaseous hydrogen chloride and in basic medium with gaseous ammonia leads to 1-(4-hydroxybutyl)pyrazoles, which manifest moderate tuberculostatic activity

MAGNETIC NANOPARTICLES -- IRON-CARBON -- BENZENESULFONIC ACID -- IR SPECTROSCOPY
Аннотация: Magnetic iron nanoparticles (MNPs) encapsulated in a carbon shells and containing sulfo groups on the surface (Fe@C-SO3H) were synthesized. The aggregative stability of aqueous suspensions of the Fe@C-SO3H nanoparticles was studied in solutions of bovine serum albumin and calcium chloride and in phosphate-buffered saline, which simulate blood plasma. It is shown that the Fe@C-SO3H particles practically do not aggregate in the phosphate buffer saline for a long time (several days). On the contrary, MNPs encapsulated in a protein shells using ultrasonic treatment form aggregates up to 110–120 nm in size under these conditions. Suspensions of the Fe@C-SO3H particles are stable in aqueous solutions of calcium chloride in the range of the solid phase concentration between 0.05 and 0.10 g L−1. The results obtained indicate the possibility of using the functionalized Fe@C-SO3H nanoparticles in vitro experiments in biological media.

Аннотация: Azo coupling of fluorinated 1,3-diketones with 4-ethoxycarbonyl-1H-imidazole-5-diazonium chloride led to the formation of 4-hydroxy-4-polyfluoroalkyl-1,4-dihydroimidazo[5,1-c][1,2,4]triazines. According to the 1H and 19F NMR data, these compounds in solution give rise to ring-chain tautomerism via opening of the C4-N5 bond, which is especially characteristic of dihydroimidazotriazines with a polyfluoroalkyl substituent longer than trifluoromethyl group
