A comparative study on mechanical and rheological properties of ternary rubber blends

Polymer blends lead to producing a new class of plastics, which may have better properties than being individual. In this study, the ternary blends of natural rubber (NR)/styrene-butadiene rubber (SBR)/nitrile rubber (NBR) were prepared via melt compounding, and then the physicomechanical properties of ternary NR/SBR/NBR blends were investigated. NR content was kept constant at 30 phr, while SBR and NBR fractions were varied simultaneously. The effect of the addition of 3 phr of ultrablend 4000 as compatibilizer on the compatibility of the rubber blends was studied. The results revealed that the use of the compatibilizer has significantly resulted in the clear stability of the scorch time and the optimum cure time of the blends. Tensile strength; stress at 100%, 200%, and 300% elongations; elongation at break %; compression strength; and compression set increase with the NBR content. There was a dramatic rise in the value of swelling ratio with the decrease of NBR. Moreover, the dynamic mechanical analysis showed some shifts in glass transition temperatures for blends to higher and lower temperatures as a function of the composition, which indicates the partial miscibility between the contributing components. Scanning electron microscopy of the tear fracture surfaces indicated that incorporation of NBR in the blends resulted in better adhesion of ternary blends and improved the tensile properties of ternary blends.

Rotational correlation times of 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy spin label with respect to heme and nonheme proteins

Noncovalent spin labeled proteins (ovalbumin, bovine serum albumin, hemoglobin, and cytochrome c) were investigated in order to follow the different type of interactions between the nitroxide radical of 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy spin label and functional groups of heme and nonheme proteins as well as the pH influence on molecular motion of the label with respect to these proteins. EPR spectra were recorded at room temperature and the computer simulation analysis of spectra was made in order to obtain the magnetic parameters. Noncovalent labeling of proteins can give valuable information on the magnetic interaction between the label molecule and the paramagnetic center of the proteins. The relevance of this interaction can be obtained from line shape analysis: computer simulations for nonheme proteins assume a Gaussian line shape, whereas for heme proteins, a weighted sum of Lorentzian and Gaussian components is assumed. In the framework of the moderate jump diffusion model for rotational diffusion, the rotational correlation time is strongly influenced by pH, because of the electrostatic interactions and hydrogen bonding.

DETERMINATION OF 3-HYDROXY-3-PYRROLINE-2-ONE IN URINE AND STUDY OF ITS EXCRETION FROM THE ORGANISM OF LABORATORY ANIMALS

cological activity. Currently, this group continues to expand. By the employees of Perm State Pharmaceutical Academy (PSPA), ruled by Professor V.L. Gein, a new biologically active compound, a 3-pyrrolin-2-one derivative – KOH-1 was synthesized. This compound is at the preclinical research stage now. The aim of this work was the development of methods for determination of KOH-1 in urine by high performance liquid chromatography (HPLC), the study of excretion KOH-1 from the organism of laboratory animals. Materials and methods. Studies on the development of methods were carried out by using a liquid chromatograph LC-20 Prominence (Shimadzu, Japan) with a diode-array detector. The validation was carried out in accordance with the requirements for bioanalytical methods, in terms of selectivity, linearity, precision and accuracy. The study of excretion of KOH-1 was performed on white non-linear male rats weighing 300-400 g. The substance KOH-1 was administered once orally in a suspension of starch mucus at a dose of 100 mg/kg. Results and discussion. As a result of the research, the method for determining the biologically active compound KOH-1 in urine has been developed. The validation showed its suitability for pharmacokinetic studies. The data on daily excretion of KOH-1 in urine after a single oral administration to rats were obtained. Conclusion. The developed conditions for the chromatographic determination of KOH-1 in urine can be used in pharmacokinetic studies, both at the preclinical and clinical stages of the study of a potential drug. The data on excretion of KOH-1 will allow to determine the ways of excretion of the preparation, and also to select a rational dosage, to identify possible contraindications to the use.

Remarkably, Atoms in Molecules analysis also confirms the existence of energetically significant unconventional anti-parallel nitrile center dot center dot center dot nitrile interaction in the crystal structure of 2. Cell cytotoxicity of the compounds performed in Dalton’s lymphoma (DL) malignant cancer cell line showed effective potency with negligible cytotoxicity in normal cells (similar to 12%).

Triarylborane catalysed N-alkylation of amines with aryl esters

The ability of halogenated triarylboranes to accept a lone pair of electrons from donor substrates renders them excellent Lewis acids which can be exploited as a powerful tool in organic synthesis. Tris(pentafluorophenyl)borane has successfully demonstrated its ability to act as a metal-free catalyst for an ever-increasing range of organic transformations. Herein we report the N-alkylation reactions of a wide variety of amine substrates including diarylamines, N-methylphenyl amines, and carbazoles with aryl esters using catalytic amounts of B(C6F5)(3). This mild reaction protocol gives access to N-alkylated products (35 examples) in good to excellent yields (up to 95%). The construction of a C-N bond at the propargylic position has also been demonstrated to yield synthetically useful propargyl amines. On the other hand, unsubstituted 1H-indoles and 1H-pyrroles at the C3/C2 positions afforded exclusively C-C coupled products. Extensive DFT studies have been employed to understand the mechanism for this transformation.
