A perception of structural similarities between two independent series of leukotriene antagonists (one emanating from FPL 55712 and one based upon the leukotrienes themselves) led to the discovery of a novel class of indole and indazole derived antagonists of peptidoleukotrienes. A systematic exploration of C-6 substituted 4-(indol-1-ylmethyl)-3-methoxybenzoic acids identified cyclopentylacetamide and cyclopentylurethane as preferred substituents. The corresponding indazoles were equipotent. These compounds are selective leukotriene antagonists with pKB values of 7.5-7.8 vs LTE4 on guinea pig trachea.
