Gassericin A, a bacteriocin that was produced by Lactobacitins gasseri LA39, was treated with lysylendopeptidase and 3-bromo-3-methyl-2-(2-nitrophenyl・mercapto)3H-indole. The fragments were recovered by SDS-PAGE and sequenced. All amino acids of gassericin A were distributed by sequence analysis and the bacteriocin did not contain Qny modified amino acids. The amino acid sequence ef gassericin ...

Protein chips technology has emerged as a promising tool for screening protein-protein interactions and characterizing the levels of proteins expressed in cells. Novel surface technologies must be improved to satisfy the specific protein orientation on the surface without denaturation, retaining non-fouling character of the surface. In order to construct facile immobilization of protein on the ...

A solvent-extraction spectrophotometric technique is proposed as a new method for determination of trace quantities of vanadium. Sodium salt of 2-mercapto-pyridine-N-oxide (thione) forms a complex with vanadium instantaneously. The purple 1:2 complex is formed of pH 2.3, easily extracted in chloroform and shows strong absorbance at 500 nm. The extracted complex is found to obey Beer's law i...

Metabolites of β2-agonists 2-(4-amino-3,5-dichlorophenyl)-2-(alkylamino)ethanols, derivatives hippuric and mandelic acids, were synthesized. The excretion profiles the target compounds metabolites with urine studied in experiments on laboratory animals. 2-(4-Amino-3,5-dichlorophenyl)-2-(isopropylamino) ethanol (9.7% administered dose) 2-(4-amino-3,5-dichlorophenyl)-2-(tert-amylamino)ethanol (0....

A series of new 3-(4-methylcoumarinyl-7-oxymethyl)-6-substitutedphenyl-5,6-dihydro-s-triazolo (3,4-b)(1,3,4)-thiadiazoles 2(a-j) have been synthesized by reacting 5-(4-methyl coumarinyl-7-oxymethyl)-4-amino-3-mercapto(4H)-1,2,4-triazole with various aromatic aldehydes by microwave assisted organic synthesis. The structure of the compounds 2 (a-j) has been confirmed by IR, (1)H NMR and mass spec...
