Outline of Final Research Achievements |
Simulation of human plasma concentrations of the teratogen thalidomide and its human metabolites is possible with a simplified physiologically-based pharmacokinetic model based on data obtained in mice with humanized liver. In vivo non-specific hepatic protein binding parameters of metabolically activated [14C]-5-hydroxythalidomide and subsequent metabolic activation in humanized liver mice can be analyzed by accelerator mass spectrometry. Human placental microsomal fractions showed detectable thalidomide 5-hydroxylation activities. Thalidomide significantly induced P450 3A4/3A5 and pregnane X receptor (PXR) mRNA levels 2- to 3-fold in human placental BeWo cells cultured with a modified medium. Thalidomide also significantly induced midazolam 1´-hydroxylation and thalidomide 5-hydroxylaion activities 3-fold. Taken together, activation of thalidomide to 5-hydroxythalidomide with autoinduction of P450 3A enzymes in human placentas, as well as livers, is suggested in vivo.
