A sustained antiplatelet effect plus target selectivity are the two major requirements for developing new antithrombotic therapies. Increasing the levels of cAMP in the platelets by the action of a prostacyclin receptor (PTGIR) agonist is a possible approach for this purpose. Researchers from the University of Michigan have presented preclinical data on their PTGIR agonist CS-585, which has shown higher blood stability, as a potential therapeutic for thrombosis.
