A series of 4-(2-[alkyl(phenylsulfonyl)amino]phenoxy}methyl)benzoic acids were identified as functional PGE2 antagonists with selectivity for the EP1 receptor subtype starting from a chemical lead 1, which was found while screening our in-house compound library. Discovery of the optimized analogs 21-23 is presented here and structure-activity relationships (SAR) are also discussed. (c) 2006 Elsevier Ltd. All rights reserved.
