Isoelectric focusing was used to study the multiple forms of acid phosphatase, arylsulfatase, β-glucuronidase and β-N-acetylhexosaminidase in lysosomes isolated from rat kidney. The isoelectric points of the main protein and hydrolase peaks were 1–1.5 units lower when electrofocusing was done...
Human liver sialidase was measured using methylumbelliferyl-N-acetylneuraminic acid as a substrate.The enzyme activity was linear for only 20 min and linearity was not improved by adding albumin, CaCl2, dithiothreitol, or Ep-459.The optimal pH was 4.5 and the apparent Km value, approximately 0.0...
Ruthenium-supported catalysts modified by the addition of Mg, Na or Ce were studied in the selective hydrogenation of paracetamol (4-acetamidophenol) to cis- and trans-4-acetamidocyclohexanol. In both series, catalysts supported on carbon or on alumina, the modified catalysts were more selective...
Two new C2 symmetric bis-cellobiose and bis-glucose azacrown derivatives were prepared according to the one-step procedure using azacrown ethers and azidosaccharides. Their complexes with aspirin and paracetamol were studied with the use of proton NMR spectroscopy. It was found that these pseudo...
The Ni(II) and Cu(II) complexes of four azo compounds (H2L1–4), namely, 2-(p-X-phenylazo)-4-acetamidophenol (X = OCH3, NO2, Br, and H for H2L1, H2L2, H2L3, and H2L4, respectively) were prepared and characterized on the basis of their analytical, spectroscopic, magnetic, and conductance data. Th...
In the present work, samarium (Sm) and nitrogen (N) doped TiO2 photocatalysts have been synthesized using conventional sol-gel process (CSP) and ultrasound assisted sol-gel process (USP). Detailed characterizations of catalysts have been performed using PL, UV-DRS, XPS, XRD, FTIR, FESEM, and EDX...
One of the reported advantages of the avicide 2-chloro-4-acetotoluidide (CAT) over its parent compound, 3-chloro-p-toluidine (CPT, DRC-1339) is its markedly lower oral toxicity in mammals. The present study was undertaken in an effort to elucidate the reasons for the differences in toxicity of t...
Theoretical calculations of the m-acetotoluidide and m-thioacetotoluidide isolated molecules were performed by using density functional theory (DFT) method at B3LYP/6–311++G (d,p) and B3LYP/6–311++G (3df,2pd) basis set levels. The Hirshfeld surfaces analysis and FT-IR and FT-Raman spectroscopy...
The construction and performance characteristics of PVC membrane (PME) and coated graphite (CGE) Fe3+ ion selective electrodes based on 1-phenyl-3-pyridin-2-yl-thiourea (PPT) are described. The electrodes exhibit a Nernstian slope of 20.2 ± 0.8 (CGE) and 19.9 ± 0.4 (PME) mV decade−1 of activit...
Chalcones or 1,3-diaryl-2-propen-1-ones are known to be useful for treating pain, inflammation, and certain diseases although their uses have not been scientifically verified. Due to the limitations of opioid and NSAID therapy, there is a continuing search for new analgesics. A series of novel n...
The thermal performances of acetanilide, meso-erythritol and an In-Sn alloy, as phase change materials (PCMs) for medium temperature applications, inside separate, spherical aluminum capsules are investigated. The average radial temperatures in the capsules are used for analyses during the charg...
Knowledge about solubility in water is required for crystallization processes, for the development of structure-property relationships, for the establishment of solubility scales, assessing environmental contamination, and for validating thermodynamic models. Approaches are desired that allow pr...
Ionic liquid-based matrix solid phase dispersion-solvent flotation coupled with high performance liquid chromatography was developed for the determination of the acetanilide herbicides, including metazachlor, propanil, alachlor, propisochlor, pretilachlor, and butachlor in rice samples. Some exp...
In this work a solution calorimetry approach was applied for determination of the sublimation enthalpies of 9 substituted acetanilides. The solution enthalpies of acetanilide and 9 its derivatives in acetonitrile were measured and solvation enthalpies were calculated by a group-additivity scheme...
The new method of ionic liquid-based homogeneous liquid-liquid micro-extraction coupled with high performance liquid chromatography was established for the determination of the four acetanilide herbicides, including metazachlor, propanil, alachlor, and butachlor in the brown rice juice. Some exp...
The Freidel-Crafts sulfination reaction of acetanilide with sulfur dioxide was catalyzed by several AlCl3-based liquid coordination complexes (LCCs), and the results were compared with that catalyzed by traditional ILs. Influences of different catalysts, ligand/AlCl3 molar ratios, and reaction c...
The reaction of N,N-dimethylbenzylamine complex of palladium(II) with isocyanides led to a cleavage of halide bridges to give (o-C6H4CH2NMe2)Pd(RNC)Cl 2. On heating of 2 in THF, an intramolecular insertion of coordinated isocyanide took place to give the dimeric iminoacyl complex 3. Treatment of...
N,N-dimethylbenzylamine complexes with Ag(I), Au(III), Zn(II), Cd(II) and Hg(II) are reported. Characterization of the complexes is made on the basis of spectroscopic techniques and analytical data. Thermal decomposition patterns of the complexes are determined by thermogravimetric (TG) and diff...
Reactions of [(C6H4CH2NMe2-C2,N)PdCl]2 (1) with (2,6-dimethoxyphenyl)diphenylphosphine (MDMPP), bis(2,6-dimethoxyphenyl)phenylphosphine (BDMPP), and tris(2,6-dimethoxyphenyl)phosphine (TDMPP) gave the corresponding complexes [(C6H4CH2NMe2-C2,N)PdCl(L)] (2a: L=MDMPP; 2b: L=BDMMP; 2c: L=TDMPP). Re...
Direct observation of the respective ortho and benzylic metalated N,N-dimethylbenzylamines by 13C and 1H FT NMR spectroscopy has been achieved. NMR assignments and the effect of temperature on the 13C resonances are reported. Evidence for an essentially trigonal benzylic carbon in α-potassio-N,...
