A novel series of oxadiazole EP1 receptor antagonists was identified by replacing the amide of a known glycine sulfonamide derivative with a 1,3,4-oxadiazole. Optimization of the substitution patterns on the three aromatic rings led to the identification of high affinity EP1 receptor antagonists. The derivative with highest affinity displayed a binding IC50 of 2.5 nM (pIC(50) 8.6). (c) 2007 Elsevier Ltd. All rights reserved.
