Bio Statement

Anticancer Agents
Our lab is interested in the design and development of anticancer agents that target topoisomerase (topo) II. Most topo II anticancer drugs are referred to as poisons because they function by trapping the cells DNA in a complex, thereby terminating DNA replication. Well known poisons include doxorubicin, etoposide, mitoxantrone, and amsacrine. While these compounds have proven their utility in the war on cancer, they are highly toxic and mutagenic, greatly limiting their therapeutic outcome. A second class of compounds that inhibit topo II activity are referred to as catalytic inhibitors. This group of compounds functions by disrupting or blocking the enzymes association with DNA or by disrupting processing of the DNA by enzymes involved in the topo-DNA cycle. Unlike poisons which are known for their antitumor activity, catalytic inhibitors are used for a variety of applications (including cardioprotectors and antineoplastic agents) and tend to show a lower toxicity. We have recently discovered a novel series of catalytic inhibitors of topo II that show broad spectrum activity in stopping cancer cell proliferation. The lab is currently applying synthetic medicinal chemistry to explore the structure-based mechanism of DNA binding and topo inhibition as well as the requirements for in vivo activity.

Opioid Receptors
Our lab has a long history of innovation in the field of opioid ligand design and development. We developed and described some of the first ligand-receptor models that explained the structural basis to selectivity of mu, delta, and kappa opioid receptors. These models have been applied over the years for virtual screening, ligand design, and in the development of mechanisms of signal transduction. Our work in modeling selectivity sites within the delta and kappa opioid receptor helped guide the design of the potent kappa antagonist guanidinyl naltrindole (GNTI). This was one of the first opioid ligands to be a priori designed using structure-based arguments derived from receptor models. Our lab is also interested in the natural product salvia divinorum or “Sally D” which contains the psychoactive salvinorin A. Salvinorin is a non-nitrogenous opioid ligand with unique pharmacological properties. Our work combining ligand binding-mutagenesis studies with molecular modeling has led to the development of a novel binding site model that has helped define the structural basis to recognition and selectivity of this natural product.
