Research Summary

Takamitsu  Hosoya(Ph.D.)

In order to achieve the promotion of human live science and drug discovery, it is necessary to develop new methods and tools realized by the innovative chemistries. Through the researches under collaboration with a number of scientists of different disciplines, we are looking to face with significant challenges including development of useful PET probes for in vivo imaging of target molecules, novel strategies for efficient PET probe synthesis, chemical tools and methods that facilitate chemical biology researches, and development of efficient synthetic methods of valuable compounds.
