Radiation Chemical Biology Lab
Machine-translated · View original
A lab studying drugs that treat cancer with alpha radiation, and the functions of sugar- and lipid-related molecules.

AboutAbout the lab
Targeted alpha therapy and functional analysis of sugar- and lipid-related molecules.
The Radiation Chemical Biology Lab studies drug development for targeted alpha therapy (TAT) and the functional analysis of sugar- and lipid-related molecules.
Targeted alpha therapy is a drug-based treatment that delivers nuclides emitting high-energy alpha particles to cancer cells and kills them, and it is attracting attention as a new treatment for intractable cancers.
The lab develops drug candidate compounds labeled with astatine-211 and conducts research with a view to a first-in-human clinical trial.
In addition, in collaboration with synthetic organic chemists, the lab creates fluorescently labeled bioactive molecules and investigates the functions of sugar- and lipid-related molecules involved in diseases such as infections, cancer, and diabetes.
Key terms
- Targeted alpha therapy (TAT)
