RaQualia and Interprotein Announce Collaborative Research Agreement on Drug Discovery Research for PPI Inhibitors

Published: Feb 01, 2013

February 1st, 2013 – RaQualia Pharma Inc. (RaQualia) and Interprotein Corporation (Interprotein) today announced that the both companies entered into a collaborative research agreement. The partnership will focus on drug discovery research for a specific protein-protein interaction (PPI)* inhibitor in the disease domain of pain.

Under the agreement, RaQualia and Interprotein will collaborate to identify new drug candidates, combining RaQualia’s core expertise in drug discovery and development, and Interprotein’s platform technology, INTENDD, on in silico screening of PPI inhibitors.

Interprotein will be eligible to receive upfront payment, contingency payment and further research milestones from RaQualia under the agreement. RaQualia will be eligible to receive the world-wide exclusive rights of all results from this collaborative research.

*About PPI:

Protein-protein interaction (PPI) is the general term of biological responses that are produced by binding of two or more protein molecules. For instance, it indicates a binding of cytokine to its receptor followed by intracellular signal transduction from the receptor. Thus, PPI plays an important role in the pathophysiology of many diseases.

About RaQualia:
