The discovery of a series of selective EP1 receptor antagonists based on a 1,2-diaryleyclopentene template is described. After defining the structural requirements for EP1 potency and selectivity, heterocyclic rings were incorporated to reduce logD and improve in vitro pharmacokinetic properties. The 2,6-substituted pyridines and pyridazines gave an appropriate balance of potency, in vivo pharmacokinetic properties and a low potential for inhibiting a range of CYP450 enzymes. From this series, GW848687X was shown to have an excellent profile in models of inflammatory pain and was selected as a development candidate. (c) 2006 Elsevier Ltd. All rights reserved.
