BACKGROUND/AIMS 3,4-Dimethoxy-2-phenylethylamine is catalyzed to its aldehyde derivative by monoamine oxidase B, but the subsequent oxidation into the corresponding acid has not yet been studied. Oxidation of aromatic aldehydes is catalyzed mainly by aldehyde dehydrogenase and aldehyde oxidase. METHODS The present study examines the metabolism of 3,4-dimethoxy-2-phenylethylamine in vitro and ...

A total of 144 weaned crossed pigs were used in a 42-d trial to explore the effects of different concentrations/combinations of benzoic acid and thymol on growth performance and gut characteristics in weaned pigs. Pigs were randomly allotted to 4 dietary treatments: i) control (C), basal diet, ii) C+1,000 mg/kg benzoic acid+100 mg/kg thymol (BT1), iii) C+1,000 mg/kg benzoic acid+200 mg/kg thymo...

Aldehyde dextran sulfonate (ADS), a modified oligosaccharide polymer, was used to prepare a new matrix structure for affinity biosensors. The principal difference between the ADS matrix and similar structures developed previously results from presence of two active functional groups in the matrix, namely, aldehyde and sulfonate. These groups perform two different functions in the matrix. The al...

in the present study, aminoazines were prepared from the reaction of amidrazone hydroiodide with various aromatic aldehydes in the presence of a solid base under microwave irradiation with power level of 850 w for 2-7 min in high yields. the amidrazone hydroiodide can also be prepared by the reaction of s-methyl isothiobenzamide hydroiodide and hydrazine in methanol under nitrogen gas. all synt...
