What we do.
Circle Pharma initiated operations in June 2014 with seed funding from Pfizer, Inc. and Mission Bay Capital, LLP; we received additional seed funding from ShangPharma Investment Group Limited in November 2015. We design and develop bioavailable macrocyclic peptide therapeutics against important clinical targets. We do this by applying a computational structure-based design approach that combines physics (conformational modeling), chemistry (innovative molecular components) and biology (protein target structure and function). We have selected intracellular protein-protein interactions that play key roles in cancer as the initial target group for our internal pipeline development.
