Development of chemical tools for the OZ research

Research abstract

Aim of our group is to develop useful chemical tools and methods that contribute to the elucidation of molecular mechanism of biological phenomena and drug discovery. Major research interests include 1) development of chemical modification methods of biomolecules using strained alkynes, 2) synthesis of diazido photoaffinity probes for target protein identification of bioactive compounds, 3) development of multicomponent conjugation methods for synthesis of multifunctional molecules based on azide chemistry, 4) synthesis of bioactive aromatic compounds via highly reactive benzyne species, and 5) development of molecular probes for bioimaging.
