About The Meeting

The idea that small, unreactive organic compounds could kill cells by undergoing biotransformation to chemically reactive metabolites stems from work done in the laboratory of Dr. Bernard Brodie at the NIH starting in the late 1960s. Since then an avalanche of chemical and biological studies of "covalent binding" has appeared in the literature. Xenobiotic-adducted proteins released by dying cells, as well as those formed by reactive metabolites that escape cells, are found circulating in plasma and are being considered as biomarkers for potential toxicity. These collective findings have significantly influenced the drug development process in industry and regulatory thinking on the part of government agencies. Yet, it is still not clear exactly how cells recognize and react when their proteins experience xenobiotic post-translational modification by chemically reactive metabolites. The talk will present a retrospective over some of the important technical and conceptual advances in the chemistry and biology of reactive metabolites that have occurred since Brodie's seminal work, and some of the questions that remain.

About Dr. Hanzlik

Dr. Hanzlik earned a B.A in Chemistry and Biology from Southern Illinois University ('66) and a Ph.D. in Organic Chemistry from Stanford University ('70) where he worked on the biosynthesis of lanosterol under the direction of Professor Eugene van Tamelen. After a postdoctoral year as a NATO-NSF Fellow in Cambridge working on chemical models for oxygenase enzymes with Professor Jack Lewis, he joined the University of Kansas where he is currently Professor of Medicinal Chemistry.

He is an active member of the scientific community, having served on NIH study sections and Editorial Advisory Boards for several journals. He is a Charter Member and Past President of ISSX and has also held elective office in the SOT and AAAS. In addition he is a member of the ACS, the Royal Society of Chemistry and the Protein Society. He has trained more than 50 graduate and postdoctoral students at Kansas where he currently teaches graduate courses in the physiological aspects of medicinal chemistry and principles of drug design. He also directs a NIH COBRE Center in Protein Structure and Function.

His research interests encompass a broad range of biology and chemistry. His laboratory has been active in the field of drug metabolism and reactive metabolite toxicology for almost 40 years. His work has focused on bromobenzene, thiobenzamide and thioacetamide as model hepatotoxins, with an emphasis on elucidating the structure and reactivity of their chemically reactive metabolites. As this work progressed it evolved to include proteomics for identifying reactive metabolite target proteins and bioinformatics for exploring the connection between protein covalent binding and the resulting cytotoxicity. Outside the lab his main interests are jogging, backpacking and windsurfing.
