The preliminary SAR of a series of novel 1,5-biaryl pyrrole EP1 receptor antagonists derived from compound 1 is described. Replacement of the benzyl group of 1 with isosteric groups was investigated. The most effective replacement was found to be the isobutyl group. The cyclopentylmethyl and cyclohexylmethyl groups were also effective benzyl replacements. The cyclohexylmethyl derivative 19 demonstrated the lowest metabolic clearance within this series. In addition, several high affinity substituted benzyl analogues were also identified. Compound 39 was found to have good bioavailability in rats and demonstrated efficacy in the established FCA preclinical model of inflammatory pain with a calculated ED50 of 9.2 mg/kg.

Replacement of the carboxylic acid group in a series of previously described 1,5-biaryl pyrrole EP1 receptor antagonists led to the discovery of various novel non-acidic antagonists. Several analogues displayed high binding affinity and high binding efficiency indices. (c) 2006 Elsevier Ltd. All rights reserved.
