ContextTaraxacum officinale Weber (TO) commonly known as “dandelion”, is a tropical Asian medicinal plant which contains taraxasterol (TX) and taraxerol (TA) in its roots, which are reported to be commercially important anticancer compounds.
AimThe present study investigates the efficacy of Mangifera indica ethyl acetate extract (MIEE) and its bioactive compound, 3β-taraxerol in the reversal of dexamethasone (DEX) induced insulin resistance in 3T3L1 adipocytes.
Alzheimer’s disease (AD) is a neurodegenerative disorder associated with cognitive impairment and cholinergic neuronal death, characteristic of the effect of time on biochemical neuronal function. The use of medicinal plants as an alternative form of prevention, or even as a possible treatment ...
Taraxerol, a triterpenoid compound, has potent anti-inflammatory effects. However, the molecular mechanisms are not clear. In the study, taraxerol concentration dependently inhibited nitric-oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) at the protein and mRNA levels and these inhibitions de...
Persistent hyperglycaemia coupled with inflammation plays an important role in the pathogenesis of diabetic nephropathy (DN). Present study examined the therapeutic potential of taraxerol isolated from the methanol extract of Abroma augusta leaf against DN using rodent model of type 2 diabetes (...
Abroma augusta L. (Malvaceae) leaf is traditionally used to treat inflammatory disorders. In our laboratory, we have scientifically validated the anti-inflammatory effect of A. augusta leaf extract. In this study, it has been aimed to evaluate in vivo anti-inflammatory effect of taraxerol isolat...
In a weakly basic non-aqueous medium a condensation reaction proceeds between dichlorotetrafluoroacetone and an α-amino acid, such that two adjacent protonic groups, amino and carboxylic, were coupled together with the ketone in a relatively stable five-membered ring. The resulting cyclic deriv...
The 313 nm photolysis of 1,3-dichlorotetrafluoroacetone in the presence of oxygen was investigated at 298 K. CF2O and CO2 were identified as the reaction products, and a mechanism is proposed to explain their formation. Evidence is obtained for the formation of CO2 by the reaction of CF2ClO radi...
Two simple and convenient methods are described for the extraction, analysis and clean-up of nine acidic herbicides in water and soil samples. The extracted acidic herbicides were converted into their methyl esters by a modified method using diazomethane. The methylated herbicides were analyzed ...
SummaryThe effect of dalapon (2,2-dichloropropionic acid, sodium salt) in different concentrations on the soluble protein content and enzymatic activity of proteases and acid phosphatases in the needles of spruce seedlings treated with this herbicide before bud development and during bud formati...
This work reports thermophysical properties measurements of binary mixtures of N,N-dimethylacetamide with 2-propanol and 2-butanol. Density, ρ, speed of sound, u, refractive index, nD, and kinematic viscosity, ν, were measured over the whole composition range at the temperatures (283.15, 298.1...
Densities and sound velocities at temperatures (298.15, 303.15, 308.15, 313.15 and 318.15) K of magnesium(II), calcium(II) and strontium(II) trifluoromethanesulfonates (triflates), as well as barium(II) perchlorate in N,N-dimethylformamide (dmf) and N,N-dimethylacetamide (dma) have been measured...
Excess molar enthalpies, HmE, over the whole composition range have been determined for the liquid mixtures N,N-dimethylformamide (DMF) or N,N-dimethylacetamide (DMA) + butan-1-amine (BA), or + hexan-1-amine (HxA), or + N-propylpropan-1-amine (DPA), or N-butylbutan-1-amine (DBA) at 298.15 K and ...
Synthesis possibility of cellulose sulfates with a low and high degree of substitution (DS) by direct homogenous sulfation of cotton cellulose in N,N-dimethylacetamide/lithium chloride (DMA/LiCl) using SO3/pyridine (Py) complex was studied comprehensively. The sulfation reactions were carried at...
To enhance the degradation of N, N-dimethylacetamide (DMAC) in aqueous solution, the natural mackinawite (NM) is introduced for catalytic ozonation in this study as it is an environmentally friendly catalyst with low cost and easy availability. The properties of the NM were initially characteriz...
Several thermophysical properties such as densities, ρ, speeds of sound, u, refractive indices, nD, and kinematic viscosities, ν, have been measured for the binary mixtures of N,N-Dimethylacetamide with 1-propanol and 1-butanol over the entire range of composition, at the temperatures (283.15,...
The aim of this work was to enhance enzymatic hydrolysis of wheat straw (WS) via a combination of alkaline hydrogen peroxide (AHP) and lithium chloride/N,N-dimethylacetamide (LiCl/DMAc) pretreatment. The physicochemical structural changes of pretreated WS were systematically characterized. Furth...
Dimethylacetamide (DMAc) acts as an efficient source of acetyl and dimethylamine gas in the presence of N,N-carbonyldiimidazole (CDI). Addition of amines to the reaction mixture delivers the corresponding amides in good to excellent yields. The acetylation of amines reported herein, which relies...
Density and sound velocity of the solutions of ionic liquids based on N-alkyl-N-methyl- morpholinium cations: N-ethyl-N-methylmorpholinium bis(trifluoromethanesulfonyl)imide, N-butyl-N-methylmorpholinium bis(trifluoromethanesulfonyl)imide, N-octyl-N-methyl -morpholinium bis(trifluoromethanesulfo...
The preparation, crystal structures, and magnetic properties of two novel mononuclear ReIV complexes of formula cis-[ReIVCl4(dmf)2] (1) and cis-[ReIVCl4(dma)2] (2) (dmf = N,N-dimethylformamide and dma = N,N-dimethylacetamide) have been studied. Both ReIV systems were synthesized through ligand s...
