Published: Nov 28, 2012

November, 2012 -- Interprotein Corporation (President, Masato HOSODA; Headquarters: Osaka, Japan; hereinafter “Interprotein”) today announced the result of assessment of small molecule PPI inhibitors that were designed by INTENDD (Interprotein’s Engine for New Drug Design), a platform technology of Interprotein, under the collaborative research between Takeda Pharmaceutical Company Limited (Headquarters: Osaka, Japan; hereinafter “Takeda”) and Interprotein.

The compounds designed by Interprotein were assessed at Takeda for binding to the target protein at the molecular level, and approximately 11%*) of the compounds tested were confirmed to bind to the target protein. Takeda will proceed with further evaluation of the compounds based on the results.

*) It is generally recognized that hit rates of compounds against protein targets through computational drug design methods are well below 11%.
