Our lab is focused on the development of novel cancer chemotherapeutic drugs targeting different biomolecular targets. To achieve these goals, we are utilizing the concepts and techniques in computer-assisted molecular modeling to design the molecules, organic chemistry to synthesize the molecules and biological assays to evaluate the molecules in cancer-relevant models. We recently discovered a small molecule inhibitor of CREB-mediated gene transcription by inhibiting the CREB-CBP interaction. This small molecule, naphthol AS-E, potently inhibits cancer cell proliferation and induce apoptosis in a variety of different cancer cells. Currently, we are investigating its mechanism of action and structure-activity relationships to design more potent derivatives as potential anticancer drugs. In addition, we are also interested in the development of novel nanotechnologies to deliver nucleic acids into the cells. This could potentially lead a new way for cancer gene therapy.
