An important research focus is to understand the target tissue pharmacokinetics of ABC and OATP transporter substrates. Imaging processes involving transporters such as absorption, distribution, metabolism, and excretion of a pharmaceutical compound within the human organism is our core expertise. Functional alteration of transporter processes such as up- or down regulation are often observed in various pathophysiological states and may contribute to pharmacoresistancy, drug-drug interactions or vulnerability towards diseases or drug side effects. Thus, the characterization of transporter function and modulation of transporter activity are another focus of our work.
Techniques, methods & infrastructure
Positron-emission tomography (PET) and magnete resonance iamging (MRI) are valuable tools to investigate such processes involved in the absorption, distribution, metabolism, and excretion of a pharmaceutical compound within the human organism. Based on the microdosing concept only sub pharmacological doses of a radiolabelled compound are used to investigate drug distribution and pharmacokinetics in healthy vlunteers and patients. This study setup eases first in human trials and first application of a novel radiotracer for clinical PET imaging.
