title: Characterisation of metabolites of 3-ethyl-3-(4-pyridyl)-piperidine-2,6-dione, a potential breast cancer drug.
abstract: The identification of metabolites from the pyridylglutarimide 3-ethyl-3-(4-pyridyl)piperidine-2,6-dione (PG, Rogletimide) was achieved using liquid chromatography-mass spectrometry with a thermospray interface (LC-TSP-MS). The urinary metabolites include PG N-oxide, the products of 4- and 5-hydroxylation in the piperidine residue (4- and 5-hydroxy-PG) and a gamma-butyrolactone derived via terminal hydroxylation in the ethyl residue. In addition to the above metabolites, several products of glutarimide ring-opening could be detected in the plasma extracts after multiple-dose treatment. Thus LC-TSP-MS is potentially a simple and rapid technique in studies of drug metabolism for the important glutarimide class of drug.
