Alpha-naphthyl isothiocyanate (ANIT) is a known hepatotoxicant that causes acute cholestatic hepatitis characterized by the infiltration of neutrophils around bile ducts and necrotic hepatocytes. The effects of glycyrrhizin (GL), 18beta-glycyrrhetinic acid (GA), matrine (MT), oxymatrine (OMT), salvianolic acid B (SAB)

To build up the research models of hepatic fibrosis in mice. Inbred wild-type FVB/N mice were either treated with alpha-naphthyl-isothiocyanate (ANIT), allyl alcohol (AA), carbon tetrachloride (CCl(4)), 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC), and silica, or subjected to common bile duct ligation (CBDL) to

A method for determining the enantiomers of 10 therapeutically relevant aminoalcohols using HPLC and precolumn derivatization was developed. Naphthyl isocyanate reacted with racemic aminoalcohols to form urea derivatives which were separated isocratically on a cellulose tris(3,5-dimethylphenylcarbamate) coated silica gel column

alpha-Naphthyl isocyanate (NI) as a derivatizing agent to separate several beta-blockers was described. This procedure is simple, rapid and gives good resolution. Experiments with NI derivatives of alprenolol showed that the isocyanate group reacted with the amino group on the

Choline is an essential nutrient which is difficult to measure because it has no native absorbance or fluorescence and only relatively unreactive functional groups. The method described here uses the reaction of the hydroxyl group on choline with 1-naphthyl isocyanate
