The overall objective of the research projects in my laboratory is to design and develop novel antitumor agents that will extend the productive lives of patients who have cancer. My research program in medicinal chemistry depends upon a structure-based approach to drug design that is intertwined with clinical oncology programs in cancer therapeutics directed by Dr. Daniel Von Hoff at the Translational Genomics Research Institute (TGen), Dr. Scot Ebbinghaus and Dr. Robert Livingston at the Arizona Cancer Center. I direct a research group that consists of a team of graduate and postdoctoral students with expertise in structural and synthetic chemistry working alongside students in biochemistry and molecular biology. In vitro and in vivo evaluations of novel agents, as well as clinical trials, are carried out in collaboration with other research groups in the Arizona Cancer Center.
At present, we have a number of different groups of compounds that target a variety of intracellular receptors. The receptors include (1) promoter complexes and (2) those involved in cell signaling pathways. Examples of specific projects are given below.
1. Targeting Oncogene Promoters
We have established that a number of important oncogene promoters, including c-MYC, Bcl-2, VEGF, and PDGF-A, have guanine repeat regions that can form G-quadruplex structures, which can be specifically targeted by small molecules, leading to suppression of gene expression. We are exploring the molecular mechanisms for control of gene expression by G-quadruplexes and how G-quadruplex-interactive compounds modulate gene expression.
2. Targeting Protein Kinases
Using a structure-based approach, we are targeting a number of kinases, including aurora kinase A. This work involves molecular modeling, synthetic medicinal chemistry and molecular biology.
