1-Nitro-2-phenylethene (NPe) induces a more potent vasorelaxant effect in rat aorta than its structural analog 1-nitro-2-phenylethane, but mediated through a different mechanism, independent of soluble guanylate cyclase (sGC) stimulation. We hypothesized that introducing an electron donor into t...

Previously, we showed that the synthetic nitroderivative trans-4-methyl-β-nitrostyrene (T4MeN) induced vasorelaxant effects in rat isolated aortic rings. Here, we investigated the mechanisms underlying the cardiovascular effects of T4MeN in normotensive rats. In pentobarbital-anesthetized rats,...

The IR and Raman spectra of the two polymorphic forms (58°- and 68°-forms) of cis-cinnamic acid were measured, and the spectral differences discussed on the basis of the crystal structures of the two forms. The IR bands related to the COOH group differ in the frequencies and band shape, reflec...

The electrolysis of cinnamoyl chloride in dry acetone anhydrous lithium perchlorate is carried out under controlled cathodic potential on a preparative scale. The ketonic reaction products are identified and their formation is rationalized through the electrogeneration of cinnamoyl free radical,...

Thermo-triggerable self-assembly was prepared by co-dissolving cinnamoyl Pluronic F127 (CinPlu) and cinnamoyl polymeric β cyclodextrin (CinPβCD) in an aqueous phase. On TEM photo, the CinPlu/CinPβCD self-assembly was 100–200 nm in diameter. The specific loading of Nile red (NR) in the assemb...

The surface modification of silica particles by an organic functional group has been intensively studied, and the modified structure can be analyzed by various experiments and simulations. Cinnamyl alcohol and cinnamoyl chloride are well known for their photo-dimerization reactions. By introduci...

In order to improve thermal stability of poly(l-lactide) (PLLA), the terminal hydroxy groups of PLLAs were converted to cinnamate esters by the treatment with cinnamoyl chloride. The resulting end-group modified PLLAs exhibited much higher thermal degradation temperature at 10% weight loss (Td10...

Pyridine compounds having a carboxyl side chain at the 2-position are attracting considerable attention for their ability. Chromium, manganese, iron, copper, zinc, and molybdenum are present as chelating agents in the human body. Picolinic acid acts as a chelating agent instead of these elements...

Reactive extraction can be used for the recovery of carboxylic acids from fermentation broth. Through the formation of complex with extractants at the two-phase interface, the carboxylic acids are partitioned into organic solvents. But, the recovery of carboxylic acids is interrupted by the cond...

In order to obtain efficient electrophoretic inks, Tridodecylamine (Dod3N), has been studied as charge control agent (CCA) in a non-polar paraffin solvent (Isopar G) for various inorganic pigments (TiO2 and Fe2O3). All hydrophobic mineral oxides, i.e. treated with octyltrimethoxysilane (C8) or d...

The extraction of hydrochloric acid by tri-n-hexylamine dissolved in n-octane has been studied, at low acid concentration, by e.m.f. measurements. The experimental data were treated graphically as well as numerically by means of the general minimizing program LETAGROP. They indicate the formatio...

The voltammetric characteristics of the title adducts [Co(Cp) (S2C2X2L] (X CN, CF3, COOCH3, 4-pyridyl, phenyl; L = tributylphosphane or tributyl phosphite) in acetonitrile solutions are reported. Both the phosphane and the phosphite adducts were oxidized and reduced through one-electron transfe...

The reaction of (E)-4-ethoxy-l,l,l-trifluoro-3-buten-2-one EtOCHCHCOCF3 1 with diethyl phosphite (EtO)2P(O)H 2 afforded a 1:1 cis- and trans-mixture of diethyl(l-trifluomethyl-3-ethoxy)allyl-phosphate EtO–CHCH–CH(CF3)OP(O)(OEt)2 3 via the 1,2-λ5-oxaphosphol-4-ene intermediate. While tributyl ...

Changes in the reactivity of phosphorus(III) esters, which are promoted by coordination to the ruthenium(II) metal centre, were the focus of this study. Nuclear magnetic resonance data, which were acquired as a function of time, suggest that the phosphite coordination to the ruthenium(II) centre...

This study involves the synthesis and characterization of novel cyclohexyl 1,3-propanediamine-N,N′-diacetate molecules as well as investigation of their cytotoxic action. New acid 1a was synthesized by reaction between (S)-2-amino-3-cyclohexylpropanoic acid and 1,3-dibromopropane, while the est...

The paper is devoted to studying the possibility of application of tributylamine (TBA) as volatile inhibitor of hydrogen sulfide corrosion (HSC) of steels. The influence of С(H2S), pH and temperatures on TBA protective action is studied as well. Amine adsorption on steel surface modified by sul...

The electrogenerated chemiluminescence (ECL) behavior of lucigenin in the presence of tributylamine (TBA) or other amines in ethanol solution at a polycrystalline gold electrode was studied under conventional cyclic voltammetric conditions. An anodic ECL peak (ECL-1 at 0.91 V vs. SCE) with two s...

Tributylamine (TBA) was found to be effective in promoting the cracking of heptane. The conversion of heptane and the yield of gas product are both distinctly accelerated. The selectivity of propylene is remarkably promoted compared with that by cracking pure heptane at 550 °C, while at the hig...

Binary mixtures of tributylamine with aromatics (toluene, ethylbenzene, o-xylene, m-xylene, p-xylene and nitrobenzene) were selected in order to investigate intermolecular interactions by calculation of their excess molar volume VmE, from density measurements. Thermal expansion coefficients αp,...

The reactive extraction process with amine extractants for the separation of KCl and NH4Cl was studied. Tributylamine (TBA) with 1-butanol has been proven to be an effective extractant. A series of influencing factors of the NH4Cl conversion rate were systematically investigated (such as reactio...
