The European Solar Telescope (EST) is a project of a new-generation solar telescope. It has a large aperture of 4 m, which is necessary for achieving high spatial and temporal resolution. The high polarimetric sensitivity of the EST will allow to measure the magnetic field in the solar atmospher...
The cytotoxic effects of 2,6-di-tert-butyl-4-methylphenyl N-methylcarbamate (terbutol) and its major metabolites were investigated in freshly isolated rat hepatocytes. Terbutol and its metabolite, especially 2,6-di-tert-butyl-4-methylphenyl carbamate (N-demethylterbutol), at a concentration of 1...
A series of 5-substituted-benzylsulfanyl-thiophene-2-sulfonamides was prepared by reacting 5-bromo-thiophene-2-sulfonamide with 5-substituted-benzyl mercaptans. The new compounds were investigated as carbonic anhydrase (CA, EC 4.2.1.1) inhibitors. The cytosolic human (h) isoforms hCA I was poorl...
A mixture of the E and Z isomers of ethyl 2-cyano-3-((4-fluorophenyl)amino) acrylate was synthesized and characterized by elemental analysis, attenuated total reflectance-Fourier transform infrared spectroscopy, 1H and 13C nuclear magnetic resonance spectroscopy. The structure of the Z isomer wa...
Solvent effects were determined for the15N NMR chemical shifts of some primary, secondary, and tertiary amines along with solvent, concentration, and counterion dependences of the corresponding amine salts. The solvent effects on tertiary-amine nitrogen resonances appear to be dominated by hydro...
Using the Ramsey formulation of the chemical shift parameter and a VB formalism, the chemical shifts of the methyl amines and methylamine hydrochlorides have been calculated. In addition, pair-interaction terms in a linear expression are presented and discussed in the light of deviations from th...
Publisher SummaryThis chapter discusses cocaine hydrochloride. Cocaine hydrochloride is also called cocaine muriate and néurocaine hydrochloride. It is present in the form of colorless granule crystals or a white crystalline powder, which is odorless and hygroscopic. It has a slightly bitter ta...
2-(4-Chlorophenyl)-2-oxoethyl 3-nitrobenzoate is synthesized by reacting 4-chlorophenacyl bromide with 3-nitrobenzoic acid using a slight excess of potassium or sodium carbonate in DMF medium at room temperature. The structure of the compound was confirmed by IR and single-crystal X-ray diffract...
[2 + 3] Cycloaddition reaction of fluorine-containing alkynes with various 2-iodoaryl ketones in the presence of CoCl2(dppf) catalyst proceeded very smoothly to give the corresponding 2- or 3-fluoroalkylated indenols in 57–98% yields. These regioisomers could be successfully separated and obtai...
In order to make a progress in discovering a new agents for chemotherapy with improved properties and bearing in mind the fact that substituted 3-hydroxy-3-pyrrolin-2-ones belong to a class of biologically active compounds, series of novel 1,5-diaryl-4-(2-thienylcarbonyl)-3-hydroxy-3-pyrrolin-2-...
The reactions of bis(organonitrile) platinum(II) complexes trans-[PtCl2(NCR)2] (R = C6H4(p-HCO), CH2C6H4(p-CH3)) with pyrroline N-oxide −O+NCHCH2CH2CMe2 afford arylamido platinum(II) complexes trans-[PtCl2{(OCR)NCCH2CH2CMe2NH}2] (R = C6H4(p-HCO) (1), CH2C6H4(p-CH3) (2)). The spectral data of 1 a...
A novel palmitic imidazoline compound, N-(2-(2-pentadecyl-4,5-dihydro-1H-imidazol-1-yl)ethyl)palmitamide (NIMP) has been successfully synthesized and characterized with Fourier transform spectroscopy (FTIR), Proton nuclear magnetic resonance (1H NMR), and Carbon-13 nuclear magnetic resonance (13...
The interactions of soy protein isolate with cyanidin-3-O-glucoside were investigated to study the protective effect of protein on anthocyanin’s stability by UV–Vis spectrophotometry, Fourier transform infrared spectroscopy, circular dichroism and fluorescence spectroscopy. Preheat treatment a...
Molybdenum doped indium oxide (In2−xMoxO3, IMO) is widely used in many electronic and optoelectronic devices due to its excellent electrical properties and optical transparency. In this work, a first attempt to produce IMO films by sol–gel dip coating was reported, starting from different reage...
A series of semi-interpenetrating network (SIPN) membranes was synthesized by using poly(vinyl alcohol) (PVA) with sulfosuccinic acid (SSA) as a cross-linking agent and poly(styrene sulfonic acid-co-maleic acid) (PSSA-MA) as a proton source for direct methanol fuel cell (DMFC) application. A bri...
Conducting polyaniline (PANI) was chemically synthesized in the presence of water-soluble aromatic polyamides containing sulfonic groups: poly-(p,p’-(2,2′-disulfonic acid)-diphenylene-tere-phthalamide) (t-PASA, rigid backbone), poly-(p,p’-(2,2′-disulfonic acid)-diphenylene-iso-phthalamide) (...
A series of promising proton conducting membranes have been synthesized by using poly(vinyl alcohol), with sulfosuccinic acid (SSA) as a cross-linking agent and poly(styrene sulfonic acid-co-maleic acid) (PSSA-MA) as proton source, which form a semi-interpenetrating network (semi-IPN) PVA/SSA/PS...
