A series of some novel 2-amino benzothiazole derivatives were synthesized and evaluated for antiinflammatory activity. The titled compounds were synthesized from the substituted aromatic amines through the intermediate substituted 1-phenylthiourea oxidation by bromine water in acidic medium. The purity of the synthesized compounds were judged by their C, H and N analysis and the structure was a...

Conductance of gap junctions in many preparations has been shown to be sensitive to cytoplasmic pH, decreasing as pH decreases below 7.5 in fish and amphibian embryos and below 7.1 in crayfish septate axon. We have found a new class of compounds, benzyl acetate derivatives, that reversibly decrease junctional conductance, gj, when applied in low concentration (approximately 1 mM). Simultaneous ...

  A theoretical density functional theory (DFT) study was performed on a series of the neutral N-phenylthiourea substituents (p-OC2H5, p-CH3, m-CH3, H, p-Cl, p-Br, m-Cl, and p-NO2) as the sensor of acetate and fluoride anions. The hydrogen bond character was analyzed as a scale ...

In this article, the catalytic activity of bis[2-(p-tolyliminomethyl)phenolato] copper(II) complex was studied, for the first time, in the oxidation of various primary and secondary alcohols to the corresponding aldehydes or ketones. The effect of different solvent was studied in the oxidation of benzyl alcohol and methanol was chosen as the reaction medium. Also the effect of different oxidant...

Biological Electronic, Optical Properties, and Vibrational Analysis of 1-benzyl-4-formyl-1H-pyrrole 3carboxamide are studied by using a combination of DFT/B3LYP method and 6-311G (d, p) basis set. Optimized parameters of the title molecule are well-matched with the experiments. The NLO properties of 1-benzyl-4-formyl-1H-pyrrole 3carboxamide have been examined with the help of Polarizability...

New N-(benzyl carbamothioyl)-2-hydroxy substituted benzamides 13, 20, and 21 were synthesized using sodium bicarbonate and benzyl amine with 2-thioxo-substituted-1,3-benzoxazines 6, 10a, b, 11c, and 12a-n. The 2-thioxo-substituted-1,3-oxazines 6, 10a-b, 11d 12a-n, and 26 were converted to the corresponding 2-methylthio-substituted-1,3-oxazines 14a-l and 24 which were then converted to 2-benzyl ...

A new alkaloid, 1,2,3,9-tetrahydropyrrolo(2,1-b)quinazolin-1-carboxylic acid (1), together with eight known compounds, 7-hydroxy vasicine (2), benzyl alcohol beta-D-(2'-O-beta-xylopyranosyl)glucopyranoside (3), benzyl alcohol O-beta-D-glucopyranoside (4), benzyl alcohol O-beta-D-primveroside (5), 3,5-dimethyl-4-hydroxy benzaldehyde (6), gluco-syringic acid (7), syringin (8), and liriodendrin (9...

The trisaccharide, 3,4-di-0-(a-L-rhamnopyranosyl)-D-galactose was synthesized using benzyl 2,6-di-0-benzyl-/?-D-galactopyranoside as starting compound. Its acetobromo derivative was coupled with 4',7-di-O-benzyl-kaempferol. The structure of the synthetic kaempferol trioside was characterised by different spectroscopic methods (UV, IR, XH, 13C NMR and MS). Chromatographic and mass spectrometric ...

The reactivity of 2-benzyl-1,2,3-triazole in palladium-catalyzed direct arylation was studied. reaction conditions for the selective synthesis 2-benzyl-4-aryl-1,2,3-triazoles moderate to high yields using phosphine-free Pd(OAc)2 catalyst and inexpensive KOAc base have been found. Then, from these 4-aryl-1,2,3-triazoles, C?H bond functionalization C5-position allowed corresponding 4,5-diarylated...
