Long-acting β₂ agonists

Abstract

Two applications claim very closely related arylsulfonamide β₂-agonists. The basic generic claim is the same in both cases with subsidiary claims covering different permutations of the same Markush structure. The claimed compounds are potent β₂-agonists whose structures suggest that they would have a long duration of action. These applications represent part of what is now a significant chemical programme at Pfizer.
