FEATURES OF INTERACTION BETWEEN 1,3- DIKETONE PHOSPHORUS-CONTAINING

DENDRIMERS AND PROTEINS

O.V. Kulynych, V.S.Starova, O.A. Zaporozhets

Taras Shevchenko National University of Kyiv, 01033, Lva Tolstogo str. 12 , Kyiv, Ukraine; e-mail: [email protected]

Phosphorus-containing dendrimers with terminal -diketone groups are a new class of materials with unique molecular structures, which causes their ca-pacity to self-aggregation and interaction with organic substances by the host-guest mechanism. These properties also make dendrimers suitable for applica-tion as nano-carriers for transmembrane transfer of the large biologically active substances, such as nucleic acids and even peptides. So, it is important to es-tablish the main features of interactions between dendrimers and various amino acids that allow to predict the proteins solubilization efficiency by dendrimer ag-gregates [1,2].

The values of critical concentration of aggregation were established for series of phosphorus-containing dendrimers with terminal -diketones groups using fluorescence spectroscopy. Experimental data confirmed that fluorescent properties and capacity to self-aggregation of these substances increase with generation. That`s why phosphorus-containing dendrimers with terminal -diketones groups of the fourth generation (Gd4) was chosen for further studies. The diameter of dendrimer`s molecules is lower than 6 nm, when the size of Gd4 aggregates reaches approximately 134 nm. It is known, that aggregates particles whose diameter is less than 200 nm are considered to be optimal for their circulation in vessels of the living organism [3].

Using the amino acids with various level of hydrophobicity (histidine, phenylalanine, tyrosine, 4-amino-3-phenylbutanoic acid, 1-amino-4-phenyl cyclohexanecarboxylic acid, S-(triphenylmethyl)-cysteine) as model compounds the capability of dendrimer to interact with both lipophilic and lipophobic organic substrates was shown. The same effect was observed at interaction of den-drimer aggregates and proteins molecules. Thus, Gd4 has similar ability to solu-bilize of different proteins, such as: ovalbumin (Mr = 4.3104 g/mol), bovine se-rum albumin (Mr = 6.7104 g/mol) and gelatin (Mr = 30104 g/mol). At that, the scattering factor of protein solution in acetone increases after addition of Gd4 due to extraction of protein molecules into dendrimer aggregates that provide the perspectives of application of such dendrimers as nano-carriers for target delivery of large biologically active substrates.

SEQUENTIAL INJECTION KINETIC-POTENTIOMETRIC DETERMINATION OF BORON

M.V. Fershal1, G.YE. Yankovych1, Ya.I. Studenyak1, Ya.R. Bazel 2. 1Uzhgorod National University, Pidhirna St. 46, 88000 Uzhgorod, Ukraine.

As an analytical signal in kinetic methods of analysis (KM) is measured during of the course of the reaction such methods exhibit some advantages over the conventional equilibrium ones. Thus, kinetic methods uses reactions with small equilibrium constants or slow rate reactions that are not suitable for equilibrium methods. From the other hand, ion-selective sensors are very useful for monitoring analytical reactions for kinetic analysis. In that reason the combi-nation of kinetic methods of analysis with the advantages of ion-selective sen-sors produces an excellent selective and sensitive technique. As the metrologi-cal characteristics of KM depend heavily on the reproducibility and stability of in-dicator reaction conditions and uniformity of manipulations the automation is the main way of considerable improving of the overall precision of kinetic methods.

This work shows the usefulness of tetrafluoroborate selective electrode as detector in SIA system in kinetic analysis of boron based on potentiometric monitoring of fluoroborate formation reaction in fluoride-acid media. In prelimi-nary studies it was shown that ion pairs of cyanine dye derivatives of N-substituted indolenines and benzothiazoles can be used as active substances for [BF4] - selective electrode preparation. The PVC membrane electrode based on an active substance formed by the ion pair of 2-[3-(5,6-dimethyl-3-nonyl-1,3-benzothiazol-2(3H)-ylidene)propenyl]-5,6-dimethyl-3-nonyl-1,3-benzothiazolium tetrafluoroborate (DMNBTC) has life-time 24 month, retainits sensitivity in strong acidic solutions and can be used for boron determination in acidic media of 67 molL-1 H2SO4 that allows to use it for fluoroborate formation reaction monitoring. The initial rate of the complex formation reaction and the area under Grans function processed potential time curves were used to con-struct calibration graphs. The effect of various interferents on the analytical sig-nal receiving and fluoroborate formation process have been examined. For the analysis process standardization the teflone potentiometric cell has been con-structed and integrated to FIAlab3500B sequential injection system (FIAlabs In-strument Systems Inc., Bellevue, USA). It was equipped with ten lateral ports multipositional Cheminert valve for redirection of reacting mixture and sample by means of a tubing system. Syringe pump was used to handle reagents to po-tentiometric cell. The working volume of the cell was 2000 l and needs only 100 l of the sample to analyze. The proposed method was successfully applied to the determination of boron in different honey samples from Transcarpation region.

FLUORESCENT DETERMINATION OF TARTRATE AD-DITIVES IN FOODS

Boiko H.I., Paustovska A.S., Zinko L.S., Zaporozhets O.A.

Taras Shevchenko National University of Kyiv 01033, Kyiv,12 L.Tolstogo str., e-mail:[email protected]

Tartrate additives are widely used in the production of canned food, jam, jelly, juice, water and various table confectioneries as acidity regulators and emulsifiers (E-334, E-335, E-336, E-337, E-354, E-483). Generally, tartrate show no significant harmful effects on the human body, but too high concentra-tions (over 30 mg per kilogram of body weight) can cause serious health dam-age. In order to control the safe levels of tartrate additives permitted in food, new method is needed to analyze food.

The determination of tartrate can be carried out by an ion and liquid chro-matography, electrophoresis. These methods are very sensitive, but have sev-eral disadvantages, such as duration of analysis and expensive equipment. More simple and economical are potentiometric and spectrophotometric ones. But the first are characterized by poor sensitivity, and the second by low se-lectivity. Fluorescent techniques are known to be sensitive, low cost, easy de-tection and widely used for the determination of anions.

The goal of this research was to develop fluorescent methodology for the determination of tartrate ions in foods using the Zr(IV) complex with morin.

The interaction nature in three-component system Zr(IV)-Morin-Tartrate have been investigated by means of spectrofluorometric methods. It has been shown that in the presence of tartrate, the fluorescence of the complex Zr(IV) with morin turned to be less intensive. A complete quenching of the emission maximum could be attributed to the replacement of the morin molecule with tartrate, which has a high affinity to Zr(IV). The scheme of analytical reactions has been proposed. The conditions (concentration of the indicator system, the acidity of the solution, the excitation and emission wavelengths) for determina-tion of tartrate using competitive reactions have been optimized.

The effect of foreign ions and sucrose that are in the water and sweets on the determination of tartrate has been studied.

Metrological characteristics have been tested on standard solutions. The method has been applied to analyze bottled carbonated and non-carbonated water, sugar syrup and peppermint candies. It has been shown that the pro-posed method is accurate, sensitive, inexpensive and suitable for the determi-nation of tartrate additives in foods.
