- The use of 3-dimensional tissue culture techniques to investigate anticancer drug transport and activity.
- Spatially resolved pharmacokinetic/pharmacodynamic modelling of anticancer drug transport and cytotoxicity.
- The design, synthesis, and evaluation of novel 1,2,4-benzotriazine dioxides as hypoxia-selective cytotoxins bioreductive drugs.
Kevin's research involves the use of multicellular layers (MCL) to investigate the extravascular transport of anticancer drugs. Multicellular layers are a model for the tumour extravascular compartment similar to multicellular spheroids but their planar geometry diffusion studies to be performed in diffusion chambers to assess drug transport.
Results of MCL studies require interpretation by modelling drug transport in tumours constrained by tumour geometry and blood/plasma drug pharmacokinetics. In collaboration with Dr Timothy Secomb at The University of Arizona and Dr Mark Dewhirst at The tumor Microcirculation Laboratory, Duke University we have developed a spatially resolved 3-dimensional PK/PD model for the extravascular transport of hypoxic cytotoxins. This program is available for download on Kevin's homepage.
These techniques can be used to assist in drug design programs in order to introduce PK/PD and, in particular, extravascular transport early in the drug design process.
