Ethynylpyridines (EPs) and ethynylbenzene (EB) are multifunctional systems able to participate in hydrogen-bonded complexes as both donors and acceptors of the H-atom. Their structures and stabilities are mainly a function of the hydrogen-bonding properties of the partner in the complex and the ...
Strontium carbonate (SrCO3) nanostructures with different morphology from bundles of nanorods to branchlet-like were synthesized by a simple and cost effective wet chemical method. Surface of nanoparticles capped by the adsorption of surface modifying agents is known for strongly influence the p...
The aim of this work is exploration of kinetic, thermodynamic and mechanistic aspects of triethylamine-mediated selenocyclofunctionalization of 4-pentenoic acid by means of phenylselenyl halides (PhSeCl and PhSeBr). The kinetics and mechanism for these reactions have been investigated by the UV–...
Triethylamine is a volatile organic compound and harmful to the environment. Development of an efficient detection and conversion method for triethylamine becomes urgent. In this work, Pt loaded three-dimensionally ordered macroporous (3DOM) WO3 materials were successfully synthesized through a ...
The simultaneous determination of xanthine (XA) and hypoxanthine (HXA) has been proved to be a feasible approach for the assessment of fish freshness. In this study, copper(II) nitrate and 1,3,5-benzenetricarboxylic acid (H3BTC) were used as precursors to prepare various Cu-BTC frameworks with t...
Glycerol-3-phosphate (G3P) is the important precursors for triacylglycerol synthesis, while glycerol-3-phosphate dehydrogenase (GPDH) determines the formation of G3P. In this study, two GDPH genes, Dtgdp1 and Dtgdp2 were isolated and identified from Dunaliella tertiolecta. The full-length Dtgdp1...
Novel one-pot homologation reactions of isoquinoline and quinoline with di-tert-butyl-TMP zincate/trimethyl borate are described. 1-tert-Butyl-3,4-dihydroisoquinoline 1 and 1-tert-butylisoquinoline 2 are formed unexpectedly under the presented reaction conditions with relative ease. A reaction m...
Novel one-pot homologation reactions of isoquinoline with lithium dialkyl-TMP-zincate⋅2MgBrCl/trimethyl borate are described. 1-Alkylisoquinolines (2, 3A, 4A, 5A, 6, and 7) and 1-alkyl-3,4-dihydroisoquinolines (3B, 4B, and 5B) are easily prepared under the presented reaction conditions. The role...
A thermodynamic modeling on the chemical vapor deposition in the B-C-O-H, B-C-O-H-He and B-C-O-H-N systems was performed. The thermodynamic equilibrium in these systems was calculated by minimization of Gibbs free energy for the conditions: 300 ≤ Tdep, K ≤ 2000; 0.001 ≤ Ptotal, Torr ≤ 760; m...
ZusammenfassungDie Bichromat-Oxydation des (-) (1R:6S)-Δ4(10)-Caren-trans-3-ols (I) in Benzol führt zu (-) (1R:6S)-Δ3-Caren-10-al (II), das durch Reduktion nach Huang-Minlon zum (+) (1R:6S)-Δ4(10)-Caren (V) reduziert wird.
Preparation of (2S, 3R)-methyl 3-phenylglycidate via enantioselective hydrolysis of racemic phenylglycidate was carried out using whole cells of Pseudomonas putida. Under optimal conditions (2S, 3R)-methyl-3-phenylglycidate could be got with ee value 99 and 48% chemical yield.
Reverse genetics in Trypanosoma brucei is dependent on the tetracycline inducible system for the precise control over the expression of both genes and dsRNA. Another independent inducible system for trypanosomes would enable the control of the activities of two different genes in the same cell, ...
Vanillic acid is found at high concentrations in many plants used in traditional medicine. It has been associated with a variety of pharmacologic activities such as carcinogenesis inhibition, apoptosis and inflammation; however, it has become most popular for its pleasant creamy odor. Since ther...
In this work the adsorption of vanillic (VA) and syringic (SA) acids onto the nonpolar resin SP700 was investigated aiming to collect data to evaluate their separation from a lignin oxidation mixture containing other phenolic compounds. The respective adsorption equilibrium isotherms in aqueous ...
A new bio-based biphenylene-containing diisocyanate, namely, 5,5′-diisocyanato-2,2′,3,3′-tetramethoxy-1,1′-biphenyl (BDI) was synthesized starting from vanillic acid – a lignin-derived phenolic acid. A series of new partially bio-based polyimides was prepared by polycondensation of BDI with...
Vanillic acid (VA), a dietary phenolic compound is generally studied for its anti-oxidative and anti-inflammatory effects. However, the effect of VA on insulin secretion and its mechanism of action has never been explored. In this study, we report that VA augments glucose-stimulated insulin secr...
Osteoarthritis (OA) is a frequently seen arthropathy that features cartilage loss and destruction. Vanillic acid (VA), is a well-known flavonoid, which possesses various pharmacological activities. However, the effects of Vanillic acid on articular cartilage destruction and the pathogenesis of O...
ObjectiveVanillic acid, also known as 4-hydroxy-3-methoxy benzoic acid has a potent effect on bone metabolism. The purpose of the present study was to specify the effects of vanillic acid (VA) on preventing inflammation and bone destruction in experimental periodontitis as inflammatory bone dise...
