The Analyst, 120(6), 1729-1732 (1995-06-01)
A rapid solid-phase extraction (SPE) procedure was developed for the quantitative isolation of three important antipyrine (dipyrone) metabolites from human plasma: 4-formylaminoantipyrine (FAA), 4-aminoantipyrine (AA) and 4-methylaminoantipyrine (MAA). Separation and quantitation were performed using micellar liquid chromatography (MLC) with a

Aminopyrine and its metabolites, including 3-hydroxymethyl-2-methyl-4-dimethylamino-1-phenyl-3-pyrazoline-5-one which is a hydroxylated metabolite of aminopyrine, were separated on a reversed-phase (C8) Radial-Pak column using a mobile phase of methanol-triethylamine-water (30:1:69) adjusted to pH 5.40 with acetic acid. Detection of the peak was

Archives of biochemistry and biophysics, 265(1), 159-170 (1988-08-15)
Four aminopyrine metabolites generated by hepatic microsomes were simultaneously assayed by high-performance liquid chromatography. The metabolites were 4-monomethylaminoantipyrine (MAA), 4-aminoantipyrine (AA), 3-hydroxymethyl-2-methyl-4-dimethylamino-1-phenyl-3-pyrazoline-5-one (AM-OH), and one unidentified metabolite. MAA was the major metabolite generated by the microsomes; its formation was induced
