PRX-08066 is a drug discovered and developed by Predix (later Epix) Pharmaceuticals [Dale S. Dhanoa et al. Patent US 7,030,240 B2], which acts as a potent and selectiveantagonist at theserotonin5-HT2Breceptor, with a 5-HT2Bbinding affinity (Ki) of 3.4nM, and high selectivity over the closely related5-HT2A and5-HT2C receptors and other receptor targets. PRX-08066 and other selective 5-HT2B antagonists are being researched for the treatment ofpulmonary arterial hypertension, following the discovery that the potent 5-HT2B agonistnorfenfluramine produces pulmonary arterial hypertension and subsequent heart valve damage. In animal studies, PRX-08066 has been found to reduce several key indicators of pulmonary arterial hypertension and improved cardiac output, with similar efficacy to established drugs for this condition such asbosentan,sildenafil,beraprost andiloprost.[1] It is also being researched for potential anti-cancer applications, due to its ability to inhibitfibroblast activation.[2]
