Research Interests
The major research efforts of our group are directed toward the development of new synthetic strategies for biologically interesting natural products and heterocycles. To understand the relationships between small molecules and biological systems, combinatorial approaches are applied in our diverse molecule library synthesis (core diversity, substituent diversity, and configuration diversity) with the assistance of automated or semi-automated equipment. Research interests include: Organic chemistry, Synthetic methodology, Natural product and bioactive molecule synthesis, Matrix-supported organic synthesis, Combinatorial chemistry, Synthesis of new glycophospholipids, Synthesis and functional study of Novel iminosugar alkaloids, Natural product-like library synthesis, Synthesis of bacterial (mycobacterial) cell wall components, Development of new chemical probes for biological applications, Pathogen host interaction, New molecules for innate immune study, Bioorganic chemistry, Chemical biology, Small molecules as chemical chaperones or specific stabilizers of protein drugs for potential treatments of lysosomal storage diseases, Development of new antibiotics, and Drug discovery. Recently, our lab is dedicated to “natural product inspired combinatorial chemistry” and its applications.
