New compound Eucommicin A

Discovered a new compound suppressing the growth of cancer stem cells from Tochu
Named "Eucommicin A"
Utilizing artificial cancer stem cells produced by IPS cell technology.
Expectations for new drug development

We found a new compound that specifically suppresses the proliferation of these cells in the components of Tochu leaf by using artificial cancer stem cells that also have the characteristics of stem cells, This research was carried out using Hekizanen's Tochu Cha tea (Eucommia Tea). Hekizanen also holds a substance patent jointly with the university.
