1. Drug Transport and Metabolism in Rat and Human Intestine
Abstract : One of the aims of this thesis was to investigate the involvement of efflux proteins, such as the P-glycoprotein (Pgp), in the drug transport in different regions of the rat and the human intestine. The intestinal extrusion of intracellularly formed CYP3A4 metabolites, including whether this extrusion might be mediated by Pgp, was also studied. READ MORE

2. Blood-Brain Barrier Transport : Investigation of Active Efflux using Positron Emission Tomography and Modelling Studies
Abstract : This thesis examines the transport of exogenous molecules across the blood-brain barrier (BBB), focusing on active efflux, using positron emission tomography (PET), computer simulation and modelling. P-glycoprotein (P-gp) inhibition was studied using [11C]verapamil and [11C]hydroxyurea was investigated as a new marker for active efflux transport. READ MORE

3. ATP-Binding-Cassette Transporters in Biliary Efflux and Drug-Induced Liver Injury
Abstract : Membrane transport proteins are known to influence the absorption, distribution, metabolism, excretion and toxicity (ADMET) of drugs. At the onset of this thesis work, only a few structure-activity models, in general describing P-glycoprotein (Pgp/ABCB1) interactions, were developed using small datasets with little structural diversity.

4. In Vivo Active Drug Uptake and Efflux at the Blood-Brain Barrier : With Focus on Drug Transport Interactions
Abstract : The blood-brain barrier (BBB) controls the movement of substances into and out of the brain. The tight junctions between endothelial cells and energy dependent transporters in the BBB influence rate and extent of drug distribution to the brain. READ MORE

5. ATP-Binding Cassette Efflux Transporters and Passive Membrane Permeability in Drug Absorption and Disposition
Abstract : Transport into and across the cells of the human body is a prerequisite for the pharmacological action of drugs. Passive membrane permeability and active transport mechanisms are major determinants of the intestinal absorption of drugs, as well as of the distribution to target tissues and the subsequent metabolism and excretion from the body.
