Promotion of life science and drug discovery researches by world’s first innovative chemistries

In order to promote life science and drug discovery researches, it is necessary to develop new methods and tools based on innovative chemistries. Through collaboration researches with many scientists of different disciplines, we are trying to develop 1) useful molecular probes for in vivo imaging of target molecules, 2) novel synthetic strategies for functional molecular probes, 3) chemical tools and methods that facilitate chemical biology researches, and 4) efficient synthetic methods for valuable compounds.

Research Theme

  • Development of world’s first strategies for efficient molecular probe synthesis
  • Development of practical molecular probes specific for target molecules
  • Development of sequence specific chemical modification methods for biomolecular probe synthesis
  • Development of novel synthetic methods of valuable compounds
