Natural Products and Related Compounds

The focus of current research is upon inventing and developing general tactics and strategies for the synthesis of natural and unnatural products of biological or structural interest. A variety of architecturally complex alkaloids, polyketides, and terpenes are selected to serve as targets of opportunity to discover novel chemistry that will have broad utility. For example, we develop new aspects of rearrangements, ring forming reactions, and iminium ion chemistry to elaborate functionalized nitrogen and oxygen heterocycles that comprise structural subunits of a diverse array of natural products. We also have a program in which we design and develop efficient strategies to prepare collections of novel small molecules having substituted heterocyclic scaffolds found in natural products and drugs for biological screening. We are particularly interested in compounds that may be used to study function and mechanism in pathways associated with cancer and neurological disorders, the ultimate goal being to discover leads for developing therapeutic agents.


Molecular Recognition in Protein-Ligand Interactions

The design and synthesis of small molecules that exhibit high affinities and specificities for selected proteins is a key step in the process of identifying potential enzyme inhibitors and receptor antagonists or agonists. Toward this goal, we have adopted a unique, multidisciplinary approach wherein synthetic organic chemistry, microcalorimetry, protein crystallography, NMR spectroscopy, and computational chemistry are integrated in systematic studies to investigate explicitly how specific variations in ligand structure affect energetics, nonbonded interactions, dynamics, and kinetics in protein-ligand interactions. The focus of current studies is upon investigating the detailed effects of introducing conformational constraints and nonpolar substituents into small molecules that bind to SH2 domains, hepatitis C viral protease, and several other proteins of biological or medicinal interest.
