Abstract
CRTh2 (DP2) is a prostaglandin D2 receptor implicated in the recruitment of eosinophils and basophils within the asthmatic lung. Here we report the discovery of a novel series of 3-indolyl sultam antagonists with low nM affinity for CRTh2. These compounds proved to be selective over the other primary prostaglandin D2 receptor (DP1) as well as the thromboxane A2 receptor (TP).
