ObjectiveTo identify inhibitors of nitric oxide production and NF-κB activity from Chromolaena odorata (C. odorata).

The feasibility of biodiesel production from tung (Vernicia montana) oil was investigated with respect to the transesterification yield and biodiesel properties. Tung oil has poor oxidation stability due to the instability of the conjugated carbon–carbon double bonds in the α-elaeostearic acid...

Lipoxygenases catalyze the oxygenation of polyunsaturated fatty acids and their derivatives to produce conjugated diene hydroperoxides. Soybean lipoxygenase-1 (SBLO-1) has been the subject of intensive structural and mechanistic study, but the manner in which this enzyme binds substrates is unce...

in this paper is reported the stereoselective synthesis of all-trans-tetraenes by reductive elimination of 1,8-dibenzoate-2,4,6-trienes with sodium amalgam. The method was applied to the syntheses of 4E, 6E, 8E, 10E-heptatetraene and β—parinaric acid methyl ester.

A high-density, polymeric C18 stationary phase (Inertsil ODS-P) or a polymeric C30 phase (Inertsil C30) provided improved resolution of the isomeric fatty acids (FAs), FA methyl esters (FAMEs), triacylglycerols (TAGs), and tocopherols with an increase in pressure of 20–70 MPa in reversed-phase ...

4-Bromobenzyl isothiocyanate when added to aerated dense suspensions of resting Candida albicans cells brings about a rapid increase in absorbance near 340 nm due to the reduction of intracellular NAD(P). No significant changes in the redox state of cytochromes were observed under these conditio...

Bis(imidazolium) chlorides based on 1,2-phenylenediamine were introduced as efficient ligand precursors in the Pd-catalyzed Mizoroki-Heck cross-coupling reactions of substituted aryl halides with activated alkenes to afford the corresponding functionalized alkenes. While high to excellent yields...

A regioselective, solvent-free and catalyst-free synthesis of isoxazoles has been successfully developed under ball milling conditions. Milling the mixtures of N-hydroxybenzimidoyl chlorides and enamino carbonyl compounds in a ball mill at a frequency of 14.6 Hz for 20–60 min afforded isoxazole...

The acrylamide monomer, N-(4-bromophenyl)-2-methacrylamide (BrPMAAm) has been synthesized by reacting 4-bromoaniline with methacryloyl chloride in the presence of triethylamine(NR3) at 0–5 °C. Copolymers of N-(4-bromophenyl)-2-methacrylamide (BrPMAAm), with glycidyl methacrylate (GMA) were syn...

The solubility of 5,10,15,20-tetrakis(4-chlorophenyl) porphyrin manganese(III) chloride (abbreviated in p-ClTPPMnCl) in N,N-dimethylformamide (abbreviated in DMF) + water solvent mixtures at 293.2–353.2 K were measured. The effects of mass fraction of DMF in the solvent mixtures at 1.00–0.80 o...

The synthesis, structure and spectroscopic properties of novel palladium(II) chloro complexes with a series of (aminoalkyloxymethyl)dimethylphosphine oxides (AOPO) are reported. The complexes with general formula PdCl2(N,N′-AOPO2) were obtained by the reaction of PdCl2(CH3CN)2 with the ligands ...

The stabilities and the heats of formation of mercury(II) n-hexylamine, di-n-butylamine and piperidine complexes have been studied in dimethyl sulfoxide (DMSO) by means of potentiometric and calorimetric measurements. Three mononuclear complexes are formed with the secondary amines, and there th...

In the present work, pseudo-emulsion hollow fiber strip dispersion system was used in which the pseudo-emulsion phase consisted of di-2-ethylhexylphosphoric acid as a carrier, n-heptane as an organic solvent and sulphuric acid with thiourea as stripping solution. Experiments were carried out in ...

This paper presents the development and construction of a sensitive new optical sensor that is highly selective to Hg2+ ion in aqueous solution. The sensing element, the newly synthesized (1Z,2Z)-N′1,N′2-dihydroxy-N1,N2-dipyridin-2-ylethanediimidamide, incorporated into a plasticized poly(viny...

The transport of mercury ions (Hg2+) through hollow fiber supported liquid membrane was examined using the extractant Calix[4]arene nitrile. Optimum condition was achieved using 4.5 pH of feed solution, 0.004 M of Calix[4]arene nitrile as extractant, de-ionized water as stripping solution and an...

Measurements are reported of the vapour pressures of di-n-hexyl ether + chloroform at 278.68 K. The molar excess Gibbs function obtained from these measurements has been compared with values predicted from the Barker generalized quasi-lattice theory with interaction parameters computed in earlie...

A new and simple two-step SFODME using 4-nitro-o-phenylenediamine (4-NOPD) as a chelating agent was developed for mercury speciation in water and fish samples by ETAAS. For the first step, methylmercury was extracted into 1-undecanol and for the second step, the Hg(II) remaining in the sample so...

Glucocorticoids, a class of metabolic hormones, impact a wide range of traits (e.g., behavior, skeletal growth, muscle maintenance, glucose metabolism), and variation in concentrations of circulating glucocorticoids (such as corticosterone), at the level of natural individual variation, in relat...

Publisher SummaryThis chapter discusses the description, methods of preparation, physical properties, stability, and methods of analysis of cortisone acetate. When obtained from 95% ethanol, cortisone occurs as rhombohedral platelets. Cortisone acetate can be obtained either as clusters of radia...

Cortisone is derived from the peripheral metabolism of cortisol and lacks biological activity. The rapid interconversion between cortisol and cortisone has been well established. The altered equilibrium between these steroids may regulate glucocorticoid activity in various tissues. We evaluated ...
