The overall, long-term goal is to contribute to the understanding of processes affecting the fates and effects of drugs in the body, in terms of structures and properties of drugs and body components, by a concerted deployment of bench-top and computational techniques. The approaches can be divided into two main streams: Subcellular Pharmacokinetics and Drug-Receptor Interactions, which are integrated into Quantitative Structure-Time-Activity Relationships.
