RIKEN Center for Sustainable Resource Science Drug Discovery Chemistry Platform Unit
Unit Leader: Hiroo Koyama (Ph.D.)
Research Summary
The main focus of our unit is to identify small molecule drug candidates suitable for animal safety studies and subsequent human clinical trials. Our dedicated scientists conduct lead compound generation, and multi-dimensional lead compound optimization on potency to target receptor/enzyme, PKPD profiles, and off-target activities through SAR development. By capitalizing on RIKEN's available expertise in X-ray crystal structure analysis, in-silico modeling studies, and HTS, we strive to expedite the drug discovery process by rational drug design. Our current therapeutic targets include rare genetic diseases and hard-to-treat cancers.
