The design, synthesis, and biological activity of novel α 4β1 and α4β7 integrin antagonists, containing a bridged azabicyclic nucleus, are reported. Conformational analysis of targets containing an azabicyclo[2.2.2]octane carboxylic acid and known integrin antagonists indicated that this azabicycle would be a suitable molecular scaffold. Variation of substituents on the pendant arylsulfonamide and phenylalanine groups resulted in potent α 4β1-selective and dual α4β 1/α4β7 antagonists. Potent compounds 11i, 11h, and 14 were effective in the antigen-sensitized sheep model of asthma. 2003 Elsevier Science Ltd. All rights reserved.
