A major focus of my laboratory is the discovery of new drugs for the treatment of cancer, primarily breast cancer and solid pediatric cancers. Our historic focus has been on the identification of novel microtubule-targeting agents from natural products and synthetic chemistry efforts. This work continues and we are also evaluating diverse natural product extracts for activity against specific types of cancer, including the molecularly defined subtypes of triple negative breast cancer and pediatric solid tumors. We conduct the initial discovery in mechanism-based and mechanism blind screens, we use bioassay-guided fractionation, in collaboration with our chemistry collaborators to identify the active constituents, and then we conduct mechanistic studies on the pure compounds and on synthetic and natural analogs.
In addition to our drug discovery efforts, a second major initiative is identifying the molecular mechanisms of action of chemically diverse microtubule targeting agents. While microtubule targeting drugs have been used successfully for decades for breast and pediatric cancers, we still do not fully understand why these drugs are effective and which patients will respond best to the different drugs. We are investigating how these drugs differentially interfere with interphase signaling events important for oncogenesis. I was initially trained in cardiovascular pharmacology and then developed expertise in drug discovery, cell biology and molecular oncology. The long-term goal of our research is to develop more effective therapies for the treatment of cancer.

Title | Taccalonolides: Mechanisms of Action and Cellular Resistance |
Status | Active |
Period | 4/2006 - 6/2017 |
Role | Principal Investigator |
Grant Detail | The goals of this effort are to identify the molecular mechanisms of action of the taccalonolides and to identify structure activity relationships of this class of microtubule stabilizing agents. The overall goal of this research project is to identify the cellular mechanisms of action and resistance of the taccalonolides, novel cytotoxic steroids with a unique mechanism of action. The taccalonolides are a new class of microtubule stabilizers and they are the first microtubules stabilizers identified that have Taxol-like effects in cells without binding to tubulin. They may have potential for the treatment of cancer. These studies are expected to identify new targets for stabilizing microtubules that lead to antitumor effects and will identify new drug targets. The information gained from these studies will also identify the signaling pathways invoked by chemically and biologically diverse microtubule stabilizers to initiate mitotic arrest and subsequent apoptosis. These studies will lead to the identification of new therapeutic targets for cancer that could provide the anticancer efficacy of the taxanes with the ability to circumvent taxane drug resistance including tubulin-mediated taxane toxicity. By comparing the activities of the taccalonolides with Taxol and discodermolide we will gain an understanding of the advantages of each stabilizer and how they can best be used to treat human cancers. The first goal of this effort is to identify the cellular binding site of the taccalonolides. We will test the hypothesis that the taccalonolides bind to and inhibit an intrinsic cellular microtubule destabilizing factor resulting in microtubule stabilization. A second goal is to elucidate the mechanisms by which the taccalonolides interrupt mitotic signaling leading to mitotic arrest and apoptosis. We will test the hypothesis that the taccalonolides inhibit Aurora A expression and activity. Drug resistance is an important problem in the treatment of cancer. We |
