title: [Metabolism and pharmacokinetics of piprozoline in rat, dog and man. 2nd Communication: Determination of metabolic profiles with the aid of an HPLC-radioactivity detection system following direct injection of urine and bile onto a reversed-phase column (author's transl)].
abstract: This paper describes the determination of metabolic profiles of 14C marked ethyl (Z-3-ethyl-4-oxo-5-piperidino-thiazolidin-2-ylidene) acetate (piprozoline, Gö 919, Probilin) in rat, dog and human urine and rat bile with the aid of an HPLC-radioactivity detector system following the direct injection of large quantities onto an analytical C-18 column. Metabolite 1 and two glucuronic acid conjugates of metabolite I were determined quantitatively, isolated and identified. Following HPLC separation, the specific detection of radioactivity permits the determination of metabolic profiles without prior clean-up so that unstable metabolites can also be analyzed.
