Research Interests

Synthesis and Biological Evaluation of Biologically Active Natural Products, Rational drug design, bioorganic chemistry, Development of Enzymatic Assays of Small Molecules, and New Chemical Tools.

Rational Drug-lead Design

Target Selection & Validation
We are working primarily on MDR-TB and MDR-Gram-positive drug targets whose 3D structures have not been previously determined. We are interested in electron transport associated proteins, glycosyltrasferases, fatty acid synthease, peptidoglycan synthease, and kinases.

Lead Generation
Based on (hypothetical) biosynthetic intermediates we design lead compounds for target proteins. We try to eliminate possible cross-reactivates against off-target proteins at early stage of drug discovery. We use a variety of lead generation techniques, including scaffold-based chemical screening, and a computational technique known as virtual ligand screening with closely related target proteins that have been characterized by X-ray crystallography.

Lead Optimization
Generation of small optimized library is our foundation for optimizing lead compounds. We typically deliver 100-150 molecules on polymer-support or in solution.

Natural Product Synthesis
We are interested in the development of efficient synthesis of biologically active natural products which are difficulty in obtaining enough amounts for in vivo assay. We are primary interested in anti-infective or anti-cancer natural products.

Bioorganic Chemistry

We are interested in unusual biological transformation found in bacterial system. We are currently elucidating a formal decarboxylative carbon-aromatic bond forming reaction found in the electron transport systems.

Development of Polymer-supported Chemistries

We are developing novel linkers for polymer-supported chemistries. Novel linkers possessing appropriate spacers are indispensable for generating library molecules efficiently. We are currently demonstrating our linkers in the syntheses of lipid I and II, and their analogues.
