研究领域

Our group interests are firmly rooted in natural product chemistry, biochemistry, and biosynthesis. The unifying theme of our researchis to gain an understanding of how natural products are made so that the organisms that produce them can be manipulated to produce 'non-natural' natural products. Nonactin is a macrocyclic polyether ionophore antibiotic. The structure is a tetramer composed of two monomers of(+)-nonactic acid and two monomers of (-)-nonactic acid. We are currently making new analogs of nonactin by genetic engineering of the nonactin biosynthesis gene cluster and through the use of recombinant, overexpressed biosynthesis enzymes in a synergistic approach with synthetic organic chemistry. The work also encompasses the synthesis and use of stable isotope labeled precursors to elucidate the mechanism of the reactions catalyzed by the nonactate poyketide synthase. The anthracycline compounds daunorubicin and doxorubicin are significant anti-cancer chemotherapeutics. We are studying the details of their biosynthesis which includes the chemistry catalyzed by the type II anthracycline PKS and the post-PKS modifications. Two emphases of the research are the enzymes DoxA (P450 monooxygenase) and DnmS (a glycosyl transferase) which are important enzymes catalyzing post-PKS processing steps. Other research includes the cloning and analysis of the biosynthesis gene clusters responsible for making a number of other polyketide metabolites and the use of combinatorial methods for producing large libraries of complex, stereo-rich, potential lead structures based upon natural product scaffolds. More information on the individual research projects can be found on the personal web pages.
