Qualitative Fourier transform infrared (FTIR) spectroscopy has long been established and implemented in a wide variety of fields including pharmaceutical, biomedical, and clinical fields. While the quantitative applications are yet to reach their full potential, this technique is flourishing. It is tempting to shed light on modern engaging and the...
Article
Recently, there has been an interest in solvent extraction for extraction organic matter from oil shale. Heating of oil shale in an inert atmosphere facilitated the extraction of the organic matter by solvent extraction. In this research, shale oil obtained by Soxhlet extraction was separated and characterized, and this was not studied previously....

Variables selection is often necessary to remove redundant data and to reduce the negative influence of spectral overlapping. In the current work, two interval variable selection methods were applied to quantify five coloring agents (Tartrazine TAR, Sunset Yellow SY, Allura Red AR, Brilliant Blue BBL, and Brilliant Black BBK) which exhibited intens...

Background : Attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy is a rapid quantitative method which has been applied for pharmaceutical analysis. This work describes the utility of first derivative ATR-FTIR spectroscopy in the quantitative determination of diclofenac sodium tablets. Methods : This analytical quantitativ...

Article
When compared to a long-straight chain terminal alkyne, a long chain terminal alkyne with a distal isopropyl unit (isobranched) isomerizes about two times faster when treated with strong base under identical conditions, and appears to follow pseudo first order kinetics. In both cases, equilibration to a 95–97:5–3 mixture of terminal:internal alkyne...
Article
Acetylacetone was successfully used as a precursor of 4-aminomethylpyrazoles and 4-aminomethylisoxazoles in a two step process at ambient temperature. In the first step, acetylacetone was transformed to the corresponding hexahydropyrimidines (1,3-diazinanes) via two consecutive one-pot Mannich aminomethylations. Hexahydropyrimidines were then treat...
Article
1,3-Disubstituted hexahydropyrimidin-5-yl(phenyl)methanone (products 1–5) were prepared from the reaction of dibenzoylmethane with primary amines and formaldehyde in the presence of Lewis acid catalyst at ambient temperature. Replication of the reaction with acetylacetone and ethyl aetoacetate yielded 1,1′-(1,3-disubstituted hexahydropyrimidine-5,5...
Article
With a total concentration of 7055 mgS/kgfuel, the content of organosulphur compounds (OSCs) in local diesel is 20 times higher than the regulated value. Analysis revealed that 30% of OSC is originated from dibenzothiophene (DBT). It is known that DBT is a hardly removable compound and selective adsorbents are often needed for its removal with low...

A series of chromium(III)-, cobalt(III)-, and iron(III)-based complexes of the general formula [(N∩O)2MCl] (1–7) (N∩O: N-salicylidene(R)amine, R = 1-naphthyl or cyclohexyl) have been applied as catalysts for the coupling reaction of carbon dioxide and epoxystyrene (styrene oxide) in the presence of tetrabutylammonium bromide (Bu4NBr) as a cocatalys...
Article
L- and D-glutamic acids, as well as trans-4-hydroxy-L-proline, are converted to the corresponding 3-guaninyl-5-hydroxymethyl-2-pyrrolidinone (4) or 3-adeninyl-5-hydroxymethyl-2-pyrrolidinone (5) nucleoside analog. The protecting group used to block the lactam nitrogen in key intermediates has a significant effect on the diastereoselectivity of the...
Article
The N-terminal domain of human soluble epoxide hydrolase (EH) has been recently reported as phosphatase. In this work, molecular dynamics (MD) simulations were performed to study the binding modes of three inhibitors (A, B and C, Scheme 1) of the phosphatase activity. Recently, compound A has been tested as inhibitor of the phosphatase activity of...

The compressibility and compactibility studies of binary mixtures containing chitosan (CS) and xanthan gum (XG) were highlighted in this article. The compressibility of the examined powders was studied according to Heckel and Gurnham equations. Results indicated that CS exhibits more ductile character than XG. Moreover, in this study percolation th...
Article
Porphyromonas gingivalis, a recognized periodontal pathogen, is a source of sphinganine bases, fatty acids, free ceramides as well as complex lipids that potentiate interleukin-1b-mediated secretory responses in gingival fibroblasts. The purpose of this study is the structural verification of the sphinganine bases and fatty acids that had been prop...
