RESEARCH INTERESTS:

Natural product chemistry

Research in the Li lab encompasses a broad spectrum of natural product chemistry in particular in the scopes of elucidation and manipulation of biosynthetic pathways to vital natural products. Natural product chemistry had its genesis in the study of naturally occurring substances, and this remains intellectual challenge and certainly a constant source of information. Current targets include glycopeptides (mannopeptimycin, enduracidine, A40926, teicoplanin, chloroeremomycin), aminoglycosides (moenomycin, minosaminomycin), and marine toxin (tetrodotoxin).

Microbial pathogenicity

The lab is also involved in a multidisciplinary study for characterizing mechanisms of microbial pathogenicity. The current targeted microbe is Klebsiella pneaumoniae K1, which is the major causative bacterium of hospital-acquired, debilitated and immuno-compromised infections in Taiwan. Its complete genome has been sequenced recently. The overall goal of the program project is to understand the relationship between virulence, CPS (capsular polysaccharide) structure, and biosynthesis of the CPS.
